Overview
The short answer, then the detail.
A Caution Concealed Entrance sign warns drivers of an entrance that is hard to see. Choose 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite in sizes from A3 landscape (420 × 297 mm) to A1 landscape (841 × 594 mm); the largest reads at about 24 metres.

"Caution Concealed Entrance" is a message people need to take in at a glance. This sign warns drivers of an entrance that is hard to see and suits site accesses, yards and driveways onto roads or car parks. The design uses a yellow warning triangle with black text.
Concealed Entrance Sign: sizes and materials
The CAUTION header flags a hazard people need to look out for; the text underneath says exactly what it is.
The legal background: under the Construction (Design and Management) Regulations 2015 the principal contractor must take steps to prevent unauthorised access to the site, and safety signs are part of that.
For signs that stay outdoors for a long time, Dibond is the most durable choice. The options are 3.5mm Correx fluted polypropylene, light and waterproof, ideal for temporary and site signs, 3mm Foamex (rigid PVC foam board), light and easy to fix indoors or for short-term outdoor use and 3mm Dibond aluminium composite, rigid and weatherproof for long-term outdoor use.
How far away will people be? As a guide we allow about 1 metre of viewing distance for every 25mm of sign height, based on the distance-factor method in ISO 3864-1: A3 landscape (420 × 297 mm) (reads at about 12 m); A2 landscape (594 × 420 mm) (reads at about 17 m); A1 landscape (841 × 594 mm) (reads at about 24 m).
Where to put it: On the approach, before the entrance comes into view.

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.
| Size | Readable from up to about |
|---|---|
| A3 landscape (420 × 297 mm) | 12 m |
| A2 landscape (594 × 420 mm) | 17 m |
| A1 landscape (841 × 594 mm) | 24 m |
Well lit or internally lit signs can be read from further away; dim areas need larger signs.

Frequently asked questions
About caution concealed entrance sign.
What size Caution Concealed Entrance sign do I need?
Pick the size by how far away people will read it. A3 landscape (420 × 297 mm) reads at about 12 m, A2 landscape (594 × 420 mm) reads at about 17 m, A1 landscape (841 × 594 mm) reads at about 24 m. These distances are a conservative guide for normal lighting.
Is there an ISO 7010 symbol for "Caution Concealed Entrance"?
No ISO 7010 symbol covers this exact message, so the sign pairs the text with the ISO 7010 W001 general warning sign.
Where should the Caution Concealed Entrance sign go?
On the approach, before the entrance comes into view. Keep it clear of anything that could block the view.
Is a Caution Concealed Entrance sign a legal requirement?
Under the Construction (Design and Management) Regulations 2015 the principal contractor must take steps to prevent unauthorised access to the site, and safety signs are part of that. Your own risk assessment decides where signs are needed.

Yes, as a custom job. Tell us the wording you need instead of "Caution Concealed Entrance", or send your logo, using the question box on this page or by calling 0161 315 1151.

Standard production is 3 working days (express 2) after you order. UK mainland delivery is £7.95 per order, free on orders of £99 and over.
Which material should I choose?
For a sign that stays up for months or years outdoors, choose Dibond aluminium composite. Correx is light, waterproof and the lowest cost for temporary use. Foamex suits sheltered spots.

Questions
Buyer questions about this product, answered. Can't see yours? Ask below and our team will reply.
How far away can the Caution Concealed Entrance Sign be read?
Work back from how far away people will be when they need to read it. Using our guide of about 1 m of viewing distance for every 25 mm of sign height: A3 landscape (420 × 297 mm) reads from about 12 m, A2 landscape (594 × 420 mm) reads from about 17 m and A1 landscape (841 × 594 mm) reads from about 24 m. In poor light, or where people are moving quickly, go a size up. The guide is based on the distance-factor method in ISO 3864-1; use it with your own risk assessment.
Which sizes can I order the Caution Concealed Entrance Sign in?
The Caution Concealed Entrance Sign comes in 3 listed sizes, from A3 landscape (420 × 297 mm) at £28.97 up to A1 landscape (841 × 594 mm) at £57.10. In between: A2 landscape (594 × 420 mm). Prices are the lowest option for each size.
I do not have artwork. Can you design it for me?
The Artwork choice on this page offers: "I will upload print-ready artwork" (free), "Add my text and logo to a clean layout (typesetting)" (£15), "Design it for me from my brief" (£35), "Redraw or vectorise my logo from a low-res file" (£50) and "Design a new logo for me" (£100). Design fees are fixed, show as their own line in the basket and cover the whole quantity of that item. Typesetting includes 1 proof and 2 rounds of changes; design from your brief includes 1 design and 2 rounds of changes. For the Caution Concealed Entrance Sign, set your file up at the size you order, for example A3 landscape (420 × 297 mm).
How much does the Caution Concealed Entrance Sign cost?
The Caution Concealed Entrance Sign starts from £28.97 with size A3 landscape (420 × 297 mm) and material 3.5mm Correx on the Saver turnaround. The price in the calculator changes live as you pick the size, material, finishing, quantity and turnaround, so you see the final price before you add to basket. No VAT is added because we are not VAT registered. Delivery is added at checkout: UK mainland delivery is £7.95 per order and free when your goods total is £99 or more after any discount code (artwork and design fees do not count towards it).
Do you charge for delivery?
UK mainland delivery is £7.95 per order and free when your goods total is £99 or more after any discount code (artwork and design fees do not count towards it), so one sign at £28.97 on its own pays £7.95, and the charge disappears once your basket reaches £99. Mainland Scottish Highlands postcodes add £10 once per order. Northern Ireland, the Scottish islands, the Isle of Man, the Channel Islands, the Isles of Scilly and the Isle of Wight are quoted before you order.
How long does the Caution Concealed Entrance Sign take to make?
On the option the calculator opens on, Saver is ready to dispatch in 5 working days, Standard in 3 and Express in 2. These are working days to dispatch, counted from when your order and artwork are confirmed, and other sizes or materials can take a day more or less: the calculator shows the exact days next to each turnaround. Courier delivery usually takes 1 to 3 working days after dispatch, and we email the tracking details when the parcel leaves us. The Caution Concealed Entrance Sign starts at £28.97 before delivery.
What type of sign is the Caution Concealed Entrance Sign?
"Caution Concealed Entrance" is a warning sign: a yellow triangle with a black border, warning of a hazard. It carries the ISO 7010 W001 symbol (general warning sign), so people understand it even if they do not read English. The colours and shapes follow the scheme set out in the Health and Safety (Safety Signs and Signals) Regulations 1996.
How thick is the Caution Concealed Entrance Sign?
The board options are 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite, so the board version is as thick as the figure in its name. Dibond is two thin aluminium skins with a plastic core, so it is rigid but still easy to fix. Foamex is a light foamed PVC board.
Will the Caution Concealed Entrance Sign show up at night?
Only where there is light on it. We print on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite, which are not reflective or glow in the dark. For car parks, yards and routes used after dark, position signs under existing lighting, or light them. Where your risk assessment calls for reflective or photoluminescent signs, you will need a specialist supplier.
Can the Caution Concealed Entrance Sign be used outside?
Yes, in the right material. Dibond is the best choice for signs that stay outside long term. Correx is weatherproof and fine outside for temporary use. Foamex copes with sheltered outdoor spots but is happiest indoors. All printed signs fade slowly in strong sun over time; check them as part of your routine and replace any that are hard to read. The Caution Concealed Entrance Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
How do I fix the Caution Concealed Entrance Sign to a wall or fence?
Foamex and Dibond boards can be screwed to a wall through holes drilled near the corners; use washers and do not overtighten, especially on Foamex. On smooth indoor walls and doors, double-sided foam tape or adhesive pads avoid drilling. Correx is best cable tied to fencing or fixed to posts. The Caution Concealed Entrance Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
Can I order now and send my artwork later?
Yes. You can upload your file on the product page, or place the order and upload later: we email you after you order. Your designer can send the file to us by email or WhatsApp with your order number, so it does not have to come through you. The turnaround clock starts once your order and artwork are confirmed, so send the file early if you have a deadline. The Caution Concealed Entrance Sign comes in 3 listed sizes, from A3 landscape (420 × 297 mm) to A1 landscape (841 × 594 mm).
What happens if my file is not good enough to print?
Our file check catches the usual problems: the wrong size, no bleed, low resolution images and text too close to the edge. We tell you what needs fixing before anything is printed, and you can send a new file. If you would rather we sort it, the typesetting option (£15, 1 proof and 2 rounds of changes) sets your text and logo on a clean layout. For the Caution Concealed Entrance Sign, set your file up at the size you order, for example A3 landscape (420 × 297 mm).
Do you check my file before printing?
Yes. A person from our team checks every uploaded file for size, bleed and resolution, and tells you if something needs fixing before anything is made. We print what you supply, so check spelling, phone numbers and dates yourself too. Production starts once your order and artwork are confirmed. For the Caution Concealed Entrance Sign, set your file up at the size you order, for example A3 landscape (420 × 297 mm).
What file should I upload?
A PDF at the finished size is best, with fonts embedded or converted to outlines. We also take AI, EPS and SVG, and high resolution JPG, PNG or TIFF files. Word, PowerPoint and Canva files are fine as a starting point, but export a full-quality PDF if you can. You can upload up to 3 files of 25 MB each on the product page, or upload later: we email you after you order. The Caution Concealed Entrance Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
What resolution does my artwork need for this sign?
For items read close up, aim for 300 dpi at the finished size. At 300 dpi an A1 landscape (841 × 594 mm) design needs about 9,933 × 7,016 pixels. Logos and text are best as vector artwork, which stays sharp at any size. Photos taken from websites or social media are usually far too small; our file check flags images that may print soft.
How do I order several of this sign?
The price shown is for one sign in the size and material you pick. Set the quantity box next to Add to basket and the basket multiplies it. If you need several different sizes or materials, add each one to the basket separately. One artwork fee covers the whole quantity of a line, and "Same artwork as another item in my basket" adds no second fee. For large runs, ask for a quote. The Caution Concealed Entrance Sign starts at £28.97 before delivery.
Will the price change at checkout?
Only delivery is added. The goods price you see in the calculator is final, with no VAT added. UK mainland delivery is £7.95 per order and free when your goods total is £99 or more after any discount code (artwork and design fees do not count towards it). Any artwork or design fee you choose shows as its own line in the basket, so you can see exactly what you are paying for. The Caution Concealed Entrance Sign comes in 3 listed sizes, from A3 landscape (420 × 297 mm) to A1 landscape (841 × 594 mm).
How much is an A2 landscape (594 × 420 mm) sign?
A A2 landscape (594 × 420 mm) sign starts at £38.33 on the lowest priced options and Saver turnaround. Pick that size in the calculator to see the price with your own material, finishing and turnaround. By material: 3.5mm Correx £38.33, 3mm Foamex £45.17 and 3mm Dibond aluminium composite £64.39. UK mainland delivery is £7.95, free once your basket reaches £99.
Can I pay for express production on the Caution Concealed Entrance Sign?
Yes. Express makes this sign ready to dispatch in 2 working days on the opening option, priced at £38.64 against £28.97 on Saver (5 days). To plan back from a date, add 1 to 3 working days for the courier after dispatch and allow for artwork: production starts once your order and artwork are confirmed. If the date is very tight, call 0161 315 1151 before you order.
Do you deliver Caution Concealed Entrance Sign to the Scottish Highlands?
Yes, with a difference in price. Mainland Scottish Highlands postcodes, for example around Inverness, Fort William, Oban and Thurso, pay the mainland rate plus £10 once per order, even when the order qualifies for free delivery. Northern Ireland, the Scottish islands, the Isle of Man, the Channel Islands, the Isles of Scilly and the Isle of Wight are quoted before you order: use Get a quote or call 0161 315 1151. We do not deliver outside the UK. On the opening option, the Caution Concealed Entrance Sign is ready to dispatch in 5 working days on Saver or 2 on Express.
How do the material prices compare on the Caution Concealed Entrance Sign?
At A3 landscape (420 × 297 mm): 3.5mm Correx £28.97, 3mm Foamex £34.56 and 3mm Dibond aluminium composite £50.09. The gap stays similar on bigger sizes, which the Prices by size table on this page shows in full. Choose on where the sign goes rather than price alone: the cheapest material is not always the one that lasts in that spot.
What other signs go with the Caution Concealed Entrance Sign?
Signs that are often needed alongside it include Caution Fragile Roof Sign, Danger Deep Water Sign, Caution Construction Entrance Sign and Caution Drain Covers Removed Sign. Each has its own page with sizes, materials and live prices, and ordering them in the same material keeps a set looking consistent. Add them to one basket: delivery is charged once, and it is free once the goods total reaches £99. The Caution Concealed Entrance Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
Is the Caution Concealed Entrance Sign portrait or landscape?
This design is landscape, in A3 landscape (420 × 297 mm), A2 landscape (594 × 420 mm) and A1 landscape (841 × 594 mm). Landscape suits wide spaces such as fences, above doors and along corridors. If you need the other way round, choose a design option and we will lay it out for you.
Can I get the Caution Concealed Entrance Sign bigger than A1 landscape (841 × 594 mm)?
The largest listed size is A1 landscape (841 × 594 mm), from £57.10. For a bigger sign, use Get a quote with the size, material and quantity, and we will price it. Boards larger than A0 travel as oversize items, which adds £15 once per order.
Will this sign bend or bow in the sun?
Foamex is a foamed plastic, so in strong sun and heat a large, thin board can bow, especially if it is only fixed at the corners. Dibond has aluminium skins and stays flat, which is why it is the choice for long-term outdoor signs. Fixing Foamex flat against a wall, or choosing a thicker board, keeps it straighter. The Caution Concealed Entrance Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
Can I trim or drill this sign myself?
Foamex and Correx cut with a sharp craft knife and a straight edge: score a few times, then snap or cut through. Dibond has aluminium skins, so it needs a fine-toothed saw and a steady hand. Drill fixing holes with an ordinary drill bit, going slowly, and keep holes at least 10 mm from the edge. Cutting into the print loses the bleed, so allow for it in the design. The Caution Concealed Entrance Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
Can I have the Caution Concealed Entrance Sign in another language, or in two languages?
Yes. Choose "Add my text and logo to a clean layout (typesetting)" (£15) and send the wording in each language; you get 1 proof and 2 rounds of changes. Keep the symbol and the sign colours the same so the meaning stays clear to everyone. Please send the translation yourself: we lay out the text you give us, we do not translate. The Caution Concealed Entrance Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
Will my brand colours print exactly?
Supply CMYK where you can. RGB files are converted to CMYK for print, which can make very bright greens, blues and oranges look slightly duller. If you need a brand colour matched, give us the Pantone reference and we match it as closely as the material allows. Small differences between a screen and the printed item are normal, because screens give off light and print reflects it. The Caution Concealed Entrance Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
Will this sign be easy to read for people with poor sight?
Strong contrast, a plain bold typeface and a size to suit the viewing distance make the biggest difference. Our standard safety sign designs use the high-contrast colour pairs set by the safety sign scheme. Place signs at eye level, well lit and without glare, and keep the wording short. The Caution Concealed Entrance Sign is printed on 3.5mm Correx, 3mm Foamex and 3mm Dibond aluminium composite.
Can someone help me choose the right options for this sign?
Yes. Call us on 0161 315 1151 or message us on WhatsApp and tell us where the sign will go, how long it needs to last and your deadline. You can also ask a question on this page; our team answers and the question may be published to help other buyers. For a price on something the calculator does not cover, use Get a quote.

Yes. Use the Get a quote page and tell us the size, quantity, material, deadline and delivery postcode, and attach any artwork you have. We reply by email or WhatsApp with a price. A quote is also the way to go for delivery to Northern Ireland and the islands. The Caution Concealed Entrance Sign is printed in our Manchester workshop or by our UK production partner, depending on the size and material.
Can I order several different designs in one order?
Yes. Add each design to the basket as its own line with its own file or online design, then check out once. Delivery is charged once per order, and becomes free when the goods total reaches £99.

The Caution Concealed Entrance Sign is printed in our Manchester workshop or by our UK production partner, depending on the size and material.
How many Caution Concealed Entrance signs do I need?
Walk the route people take and put a sign wherever someone needs the message and would otherwise miss it: each entrance, each approach to the hazard and each change of direction. Larger areas usually need the same sign more than once, in the size that suits each viewing distance.
