Overview

If "Danger Demolition in Progress" needs saying clearly, this is the sign, and danger demolition in progress sign printing is what we do. It warns that a structure is unsafe or coming down, and you will find it in demolition sites and damaged buildings.

Danger demolition in progress sign printing: choosing the board

There is a board for each kind of spot in our danger demolition in progress sign printing range:

  • 3.5mm Correx, the fluted plastic board: light, waterproof and cheap to replace, which is why it is the site-sign favourite
  • 3mm Dibond, aluminium skins on a solid core, the one to pick for a sign that stays outside for years
  • 3mm Foamex, a rigid PVC foam board that screws or sticks up easily and is happiest indoors or out for a season

Short job, Correx. Indoors, Foamex. Long job outdoors, Dibond.

The message

It reads "Danger Demolition in Progress". White board, strong coloured header: the layout people expect to see at a site gate. DANGER is kept for hazards that could kill or seriously hurt someone.

Where to fix it

On the hoarding or fence round the structure. Put the board at the site entrance where every visitor has to pass it.

The right size for danger demolition in progress sign printing depends on the reading distance. Rule of thumb from ISO 3864-1: each 25 mm on the short side of the sign gives roughly a metre of reading distance. That makes A1 to about 24 m, 700 x 1000 to about 28 m and A0 to about 34 m. Anything read from a distance or a moving vehicle wants the larger sizes.

One board with all the site rules saves a row of separate signs on the gate.

The Construction (Design and Management) Regulations 2015 expect the site rules and hazards to reach everyone on site, visitors included. A single board at the gate does that in one go.

Send a print-ready PDF, build it in the online designer, or pay for our artwork service (you get 1 design and 2 rounds of changes). Whichever you pick, a person checks the file before it prints. Every danger demolition in progress sign printing order is made to order and dispatched from the UK. We charge £7.95 to send it anywhere on the UK mainland, and nothing once your goods come to £100 or more after discounts. Mainland Highlands postcodes add £10; Northern Ireland, the islands, the Isle of Man, the Channel Islands, Scilly and the Isle of Wight are quoted. Full details are on the delivery page.

Which size do I need?

A safety sign must be large enough to read from where people will see it. Our conservative guide, based on the distance-factor method in ISO 3864-1, is about 1 metre of viewing distance for every 25 mm of sign height (the shorter side). Use it with your own risk assessment.

SizeReadable from up to about
A1 (594 × 841 mm)24 m
700 × 1000 mm28 m
A0 (841 × 1189 mm)34 m

Well lit or internally lit signs can be read from further away; dim areas need larger signs.

Questions

Quick answers about danger demolition in progress sign printing.

How big should the Danger Demolition in Progress sign be?

Think about the furthest point someone needs to read it from. For "Danger Demolition in Progress", A1 (594 × 841 mm) for readers up to 24 m away, 700 × 1000 mm for readers up to 28 m away and A0 (841 × 1189 mm) for readers up to 34 m away. Those distances assume ordinary light, so if it is gloomy or people are driving past, step up one size.

Is there a standard pictogram that says "Danger Demolition in Progress"?

Not one that fits this wording, so the "Danger Demolition in Progress" sign is a text-only design in the standard site board header colours.

Where should the "Danger Demolition in Progress" message go so people act on it?

The right place is on the hoarding or fence around the structure. Walk the route yourself and make sure it is seen from the direction people come.

Am I legally required to display "Danger Demolition in Progress"?

The Construction (Design and Management) Regulations 2015 expect site rules and hazards to reach everyone on site, visitors included. One board at the gate carrying several messages does that in a single place. How many you need and where comes down to your own risk assessment.

Will the Danger Demolition in Progress sign survive outdoors?

Yes, if you order it in Dibond or Correx; both cope with rain. Foamex is better kept indoors or somewhere sheltered. Pick the material in the options before you order.

Why is the Danger Demolition in Progress sign in these colours?

Site boards gather several safety messages under one coloured header. The "Danger Demolition in Progress" sign uses that standard layout, so people read its meaning before the words.

Is anything added to the price of the "Danger Demolition in Progress" sign at checkout?

Only delivery, where it applies. The figure on the page is the one you pay at checkout. The £51.39 starting price for the "Danger Demolition in Progress" sign is the full price of the goods. Postage to the UK mainland is £7.95 per basket, not per item, and free when your goods total £100 or more.

Asked by buyers

How cheaply can I get hold of the Danger Demolition in Progress Sign?

Picked the way the page first loads, with A1 (594 × 841 mm) and 3.5mm Correx, the Danger Demolition in Progress Sign comes to £51.39. Any other mix of options, a faster turnaround included, gets its own price the moment you choose it, and that figure is what you pay at checkout. Only delivery is left to add. On its own the opening price of £51.39 would add £7.95 for mainland delivery; reach £100 of goods and that goes to zero.

Which turnaround speeds can I choose for the Danger Demolition in Progress Sign?

Allow 5 working days on Saver, 3 on Standard or 2 on Express before the Danger Demolition in Progress Sign is handed to the courier, based on the options the page opens with. Weekends and bank holidays are not counted, and nothing starts until the order is paid and the artwork is confirmed. Pick another size or material and the days beside each speed update, sometimes by a day. After it leaves us, the courier normally delivers in one to three working days and you get the tracking link by email.

Is delivery extra on top of the price of the Danger Demolition in Progress Sign?

Send it to a UK mainland address for a flat £7.95, or for free when the goods in the basket add up to £100 or more after discounts; artwork and design charges do not count towards that. An order of just this at the opening price of £51.39 is under £100, so it pays the £7.95. We price delivery first for Northern Ireland and for the Isle of Wight, the Channel Islands, Scilly, the Scottish islands and the Isle of Man; Highland addresses on the mainland just pay £10 extra, one time per order.

Which artwork services are offered with the Danger Demolition in Progress Sign?

Several routes, all chosen under Artwork on this page. Send your own finished file (no charge), we set your words and logo on a tidy layout, called typesetting (£15), we design it from your brief (£35), we redraw a blurry or low quality logo as sharp vector art (£30) or we create a brand new logo (£50). Typesetting and design from a brief each come with one first draft and two rounds of changes. The fee is the same whatever quantity you order and shows separately in the basket. Sizes for this site board go from A1 (594 × 841 mm) at the small end to A0 (841 × 1189 mm), 3 in all.

Which sheet material goes into this site board?

You can have "Danger Demolition in Progress" made on 3mm Foamex, 3mm Dibond aluminium composite and 3.5mm Correx. Foamex, a foamed PVC board, is light with a smooth face and best indoors or somewhere sheltered; a thicker sheet stays stiffer at larger sizes. Dibond, an aluminium composite, keeps flat and rigid in all weathers and is the pick for permanent outdoor signs. Correx, a fluted polypropylene, weighs least and costs least, copes with rain and suits short-term signs.

Which is the smallest and which the biggest site board I can order here?

The table has 3 sizes. At the small end, A1 (594 × 841 mm) costs from £51.39; at the top, A0 (841 × 1189 mm) costs from £85.17. Each figure is for the cheapest set of options at that size. Unsure? Measure where it will go and check the view from the spot people will stand.

Can I leave this site board outside?

Out of doors, the board decides how long "Danger Demolition in Progress" lasts. Dibond is built for long spells outdoors. Foamex belongs indoors or under cover; out in hot sun and rain it can start to bow over time. Correx shrugs off rain and is fine outside for temporary signs. All print fades gradually in strong sunlight, so if a sign is staying up for a long time, point it away from the midday sun where you can. For this site board, the material can be 3mm Foamex, 3mm Dibond aluminium composite or 3.5mm Correx.

Where is the best spot to put up the Danger Demolition in Progress Sign?

Right by the main way in, turned towards people as they walk up, at a height they can read from outside the site. Fix it firmly to the hoarding, the gates or the Heras fence panels so wind cannot swing it or lift it off. A site with two or more ways in needs one board at every entrance. For this site board, the material can be 3mm Foamex, 3mm Dibond aluminium composite or 3.5mm Correx.

How do people usually fix up this site board?

Putting up "Danger Demolition in Progress" takes very little kit. A drill, for a hole near each corner. Then a handful of cable ties for a fence, or a stake or two; ties through the flutes hold firmly. If the wall is smooth and indoors, double-sided foam tape or sticky pads avoid drilling altogether. For this site board, the material can be 3mm Foamex, 3mm Dibond aluminium composite or 3.5mm Correx.

And the largest site board, A0 (841 × 1189 mm): how much is that one?

From £85.17, with the cheapest settings and the Saver service. Material by material, it is 3.5mm Correx at £85.17, 3mm Dibond aluminium composite at £135.35 and 3mm Foamex at £98.13. Add £7.95 for UK mainland delivery, or nothing at all once the goods reach £100. Select it on the page and swap materials, finishes and speed to watch how the figure moves.

I am not a business. Can I buy just one site board?

Of course. Anyone can order, with no trade account and no minimum beyond one. Prices for the Danger Demolition in Progress Sign begin at £51.39, checkout works without an account and you pay by card. Parents, clubs, churches and small shops order single items all the time. On its own the opening price of £51.39 would add £7.95 for mainland delivery; reach £100 of goods and that goes to zero.

I need several site boards, some in different sizes. How do I buy them?

Each price on the page is for a single site board in the size and material chosen. Put the number you want in the box beside Add to basket and the total multiplies. For a different size or material, add it as a separate line; the basket keeps them apart. An artwork fee is charged once per line, whatever the quantity, and choosing to reuse the artwork from another item in your basket costs nothing more. Very large runs can go through Get a quote. Before delivery, this site board costs from £51.39.

Could you price a 700 × 1000 mm site board for me?

From £77.03, with the cheapest settings and the Saver service. Material by material, it is 3.5mm Correx at £77.03, 3mm Dibond aluminium composite at £117.85 and 3mm Foamex at £86.03. Add £7.95 for UK mainland delivery, or nothing at all once the goods reach £100. Select it on the page and swap materials, finishes and speed to watch how the figure moves.

Could the total go up after I reach the checkout?

No surprises: what the page shows for this site board is the goods figure you pay at checkout. Delivery is the one extra, £7.95 to a UK mainland address, and it drops away when the goods reach £100 after discounts. Paid artwork help shows up as its own basket line, so you can check each amount before paying. Before delivery, this site board costs from £51.39.

Do you send to Northern Ireland or the islands?

Yes, anywhere in the UK, though the price differs by area. A Highlands postcode on the mainland pays the usual rate plus a single £10 for the order, and that £10 still applies when the rest of the delivery is free. Northern Ireland gets a price worked out first, as do the Isle of Wight, the Channel Islands, Scilly, the Scottish islands and the Isle of Man: send your postcode through our Get a quote page or the Contact page. We cannot send anything outside the UK. Before delivery, this site board costs from £51.39.

Our event is close. Can the Danger Demolition in Progress Sign be rushed?

Yes. Choose Express and the Danger Demolition in Progress Sign can be on the way in 2 working days on the opening option, for £68.52, where Saver is £51.39 and takes 5 days. Then give the courier one to three working days, and send the artwork with the order, because the clock does not run until the file is sorted. If the date is really tight, message us on the Contact page before paying and we will tell you honestly.

Someone else is putting our file together. How does it reach you?

Easiest route: they send the finished file to whoever placed the order, and it gets uploaded after ordering. Up to 3 files of 25 MB each are fine. They can also reach us through the Contact page, as long as they quote your order number so it lands on the right job. Production waits for the checked file, so a late file means a later dispatch date. For this site board, the material can be 3mm Foamex, 3mm Dibond aluminium composite or 3.5mm Correx.

How many pixels does a photo need to print well on this site board?

Big items seen from a distance only need 100 to 150 dpi at full size. So an A0 (841 × 1189 mm) layout wants about 3,311 by 4,681 pixels. Keep lettering and logos as vectors if you can. An image copied off a web page or a social post rarely has enough pixels; if yours looks likely to print soft, our file check flags it.

Will anyone look at my file before it is printed?

Yes, a real person on our team opens every uploaded file and checks the size, the bleed and the resolution. If something is off, you hear from us before anything is made. We print what you send, though, so read the spelling, numbers and dates yourself as well. Making starts when the order and the file are both confirmed. Sizes for this site board go from A1 (594 × 841 mm) at the small end to A0 (841 × 1189 mm), 3 in all.

I am not a designer. What if the file I send turns out to be unusable?

That is why a person looks at every upload before anything is printed. Typical snags are a document at the wrong size, missing bleed, blurry photos and words sitting too near the trim. If we spot one, we explain what to change and you send a fresh file. Or hand it over to us: for £15 our typesetting places your wording and logo on a neat layout, with one first draft and two rounds of changes. Sizes for this site board go from A1 (594 × 841 mm) at the small end to A0 (841 × 1189 mm), 3 in all.

Can I send a Word or Canva file for the Danger Demolition in Progress Sign?

Word, PowerPoint and Canva are a fair place to start, but export a high quality PDF from them before uploading. Our first choice is always a PDF at the ordered size with fonts embedded or outlined, followed by AI, EPS or SVG, then high resolution JPG, PNG or TIFF. You can add three files, each up to 25 MB, on this page, or upload them after ordering from the email we send. Make the artwork for this site board the same size as the one you order, such as A1 (594 × 841 mm).

What thickness is the Danger Demolition in Progress Sign, and does it feel sturdy?

That depends on the board you tick: Correx at 3.5 mm, Dibond at 3 mm and Foamex at 3 mm. Dibond feels stiff because a plastic core is sandwiched between two thin aluminium sheets, yet it is still simple to screw or stick up. Foamex is foamed PVC, so it weighs very little in the hand. For this site board, the material can be 3mm Foamex, 3mm Dibond aluminium composite or 3.5mm Correx.

Do builders and contractors buy the Danger Demolition in Progress Sign from you?

Yes: the Danger Demolition in Progress Sign sits in our Builders & Construction section, next to other things builders and contractors buy for sites, extensions and renovations. Prices begin at £51.39. 3 sizes are listed, starting at A1 (594 × 841 mm). The material choices are 3mm Foamex, 3mm Dibond aluminium composite or 3.5mm Correx. Also in that section: Scaffold Banners and Caution Fragile Roof Sign. One basket can hold the lot, and delivery is free once the goods reach £100.

We are putting up a full set of signs at our premises. Which ones sit well next to this one?

A school corridor, a shop floor or a club house rarely needs just one notice. Two that often go up beside this one: Site Safety Notice Sign and Warning Construction Site Sign. Keep every sign in one board type so the set matches, look up sizes and prices on each page, then check out once: one delivery charge for the whole basket, free over £100 of goods. You will also find this site board in our Builders & Construction section.

It gets dark early in winter. Can people still read the Danger Demolition in Progress Sign in the evening?

Not in pitch darkness. Pick Correx, Dibond or Foamex and it is the same story: nothing on this page reflects headlights or glows by itself. Fix it where a street light, porch light or security lamp already shines, or fit a small light above it. Where a risk assessment asks for photoluminescent or reflective signs, those need to come from a specialist maker rather than from us. For this site board, the material can be 3mm Foamex, 3mm Dibond aluminium composite or 3.5mm Correx.

Does the material change the price of the Danger Demolition in Progress Sign?

Taking the smallest size, A1 (594 × 841 mm), as the example: 3mm Foamex at £71.71, 3mm Dibond aluminium composite at £83.74 and 3.5mm Correx at £51.39. Larger sizes follow a similar pattern, and the full grid sits in the size table further up the page. Think about where it is going first: a cheap material in the wrong spot can end up costing more.

I am ordering this site board for a school or charity. Do I need to open an account?

No account is needed. Guest checkout lets a parent, volunteer or club secretary order once and pay by debit or credit card through Stripe. The price you see is the price you pay at checkout, and the confirmation email you receive lists the items and the amount paid for your records. If the committee needs a price agreed before anyone pays, the Get a quote page is the better starting point. Nothing is printed ahead of time: each site board is made to order for you.

Next year we will want the same site board again. Is reordering easy?

Very. Choose the same product with the same options and upload the same file, and it is made again exactly as before. Save the final print file somewhere safe, as that makes a repeat order a two-minute job. Before you repeat it, read the wording again: dates, prices, opening times and contact details are the things that go out of date. Sizes for this site board go from A1 (594 × 841 mm) at the small end to A0 (841 × 1189 mm), 3 in all.

Do I pay delivery on each item in my basket?

No. One delivery charge covers the whole basket, so adding the Danger Demolition in Progress Sign to other items does not add a second one. It is £7.95 to a UK mainland address and nothing once the goods total £100 after any discount code. Using the same design on two items? Pick the reuse-artwork option on the second one and you pay the artwork fee just once. Each line keeps its own size and quantity.

Do I have to register before I can buy?

There is no need to sign up. Pay as a guest with a bank card, handled securely by Stripe, and you still get an order confirmation email and a tracking email on dispatch. An account is optional; it just keeps your order history in one place. Nothing is printed ahead of time: each site board is made to order for you.

We need a few different designs. Do they each need their own order?

No. Each design goes into the basket as a separate line with its own file or online design, and you pay for them all in one checkout. Delivery is counted once for the whole order and costs nothing when the goods reach £100. If two lines share the same artwork, pick the artwork option that reuses a file already in your basket, so any design fee is only paid once. Sizes for this site board go from A1 (594 × 841 mm) at the small end to A0 (841 × 1189 mm), 3 in all.

Our treasurer needs a receipt for the accounts. What do we get?

Keep the order confirmation email we send: it itemises the purchase and the payment, and works as a plain receipt for your records. The total at checkout for this site board is the goods price on the page plus delivery, so the email matches what left the account. Need something more formal for an audit or a grant claim? Message us from the Contact page with your order number. Before delivery, this site board costs from £51.39.

I am not sure which options to pick for this site board. Can someone advise me?

Yes. Type your question into the box on this page and a real person replies. Mention where the site board will be used, how long you need it to last and the date you need it by. Answered questions may be shown on the page for other buyers, so leave personal details out of it. Private questions can go through the Contact page, and anything the options here cannot price can go through the Get a quote page. Before delivery, this site board costs from £51.39.

Can I send this site board back if I no longer need it?

If it arrives faulty, damaged or not what you ordered, yes: under the Consumer Rights Act 2015 we reprint or refund. A change of mind is different. Each order is made to your specification, and reg. 28(1)(b) of the Consumer Contracts Regulations 2013 takes those goods out of the 14-day right to cancel. Before production starts, though, you can cancel for all your money back. Sizes for this site board go from A1 (594 × 841 mm) at the small end to A0 (841 × 1189 mm), 3 in all.

The parcel turned up damaged. How do I sort it out?

Take photos of the damage and the box it came in, then send them through the contact form within 48 hours of delivery, with your order number. Hold on to the item rather than posting it back; we reply and arrange a reprint or refund. This sits alongside your legal rights, which the returns page covers. Choose Saver and this site board leaves us after 5 working days; Express brings that down to 2.

Bleed and dpi mean nothing to me. Can I still get printing done?

Yes. You do not need any print knowledge to order the Danger Demolition in Progress Sign. Send us your words and logo with the typesetting option (£15) and we build the layout, then you get a first draft and two rounds of changes. Whatever you choose, a real person looks at the file before printing.

Can the Danger Demolition in Progress Sign carry wording in two languages, for example English and Welsh?

Yes. Choose the typesetting option (£15) and send us the words in every language you want on it. That covers one first draft and two rounds of changes. We lay out the text exactly as you supply it but we do not translate, so have the translation done first. Leave the symbol and colours as they are, so the meaning is clear whichever language someone reads. Sizes for this site board go from A1 (594 × 841 mm) at the small end to A0 (841 × 1189 mm), 3 in all.

What if A0 (841 × 1189 mm) is still too small for the Danger Demolition in Progress Sign?

We can still help. Put the size you need, the material and the quantity into the quote request form and we will send a price. For reference, the listed range ends at A0 (841 × 1189 mm), and that size costs £85.17 or more. Bear in mind that anything past A0 goes by oversize courier, a one-off £15 on the order.

Could the Danger Demolition in Progress Sign go on a door, say an office or classroom door?

Start with the position: eye level, on the push side or on the wall next to the frame, so the message is still visible with the door open. Fix it with double-sided foam tape or screws. A 3mm Foamex board on foam tape also sits well on a flat door. On a fire door, get the go-ahead from whoever looks after the building before any screws go in. For this site board, the material can be 3mm Foamex, 3mm Dibond aluminium composite or 3.5mm Correx.

What is the safest way to clean this site board?

Treat "Danger Demolition in Progress" gently: a soft cloth and soapy warm water, a rinse, then a dry. Strong cleaners, solvents and scourers can take the shine off the print or lift it, so leave them in the cupboard. Store spares flat, not leaning, to stop them bowing. For this site board, the material can be 3mm Foamex, 3mm Dibond aluminium composite or 3.5mm Correx.
