Acrylic Site Notice Boards for Construction Sites

Large custom acrylic site notice board by Gigantic Signs mounted on a construction site hoarding, with fabricated clear acrylic document sleeves holding pre-start checklist sheets and a leaflet holder -- gigantic signs adelaide

Need a site notice board for an Adelaide construction site? The short answer: Gigantic Signs builds custom acrylic notice boards at our Kent Town workshop -- the printed board plus fabricated document sleeves, checklist pockets and even a built-in lost-time-injury counter -- made as one turnkey unit rather than a bare frame you have to add holders to yourself.

We've been making signs for Adelaide businesses for over 30 years, and site notice boards are a job our construction and facilities customers come back for again and again. Everything is designed, printed and fabricated in-house at Kent Town, so when a site manager needs the board to do more than just display a printed layout, we can build that in rather than send you off to source it separately.

What goes on a site notice board?

A site notice board is the single point where a construction or industrial site posts the information every worker and visitor needs to see before they start. On an acrylic board that content is usually a mix of a permanently printed layout and swappable documents held in pockets. The common elements are:

  • Site rules and safety induction -- printed straight onto the acrylic so it can't be pulled down or go missing.
  • Pre-start checklists and SWMS -- the paperwork that changes daily or per task, held in clear document sleeves so crews can read and swap it.
  • Emergency and evacuation information -- assembly points, first-aid contacts and the site map, often paired with standard compliant safety signs elsewhere on site.
  • Notices and leaflets -- toolbox-talk handouts, contact cards and updates, held in angled leaflet holders so they can be taken.

The printed acrylic panel is the backbone. Everything else -- the holders, the pockets, any built-in display -- is fabricated around it so the whole board arrives as one finished unit.

What size should a site notice board be?

Site boards run large so they can be read at a glance and carry several documents at once. A common size we build is around 1400 x 1300mm, which comfortably fits a printed safety layout down one side and a grid of document sleeves and holders down the other. Smaller boards suit a site office or a lunchroom wall; bigger ones suit a main gate or a muster point where a whole crew gathers. Because the board is printed acrylic, you're choosing a panel size first and then deciding what gets fabricated onto it. You can price a plain acrylic panel in your exact dimensions instantly below, then talk to us about the holders and extras.

Can you add document holders and checklist pockets?

Yes. This is the part that separates a real site board from a printed sheet screwed to a wall, and it's where we do the most custom work. We fabricate clear acrylic document sleeves, A4 checklist pockets, angled leaflet holders and pen holders, and we fix them to the board wherever your site process needs them. These aren't picked from a standard options list -- we make them to suit the board, so the pockets sit where your crews actually reach for the paperwork.

A good example: a cadet at a national infrastructure contractor came to us for a large acrylic notice board, then realised they also needed somewhere to hold pre-start checklists and leaflets on the same board. Rather than tape a hardware-store holder onto the front, they asked us to build the lot. Their words were basically "I want you to make my whole sign, please." So we fabricated the document sleeves and holders in acrylic and mounted them as part of the board, and it left Kent Town as one clean, finished unit ready to hang on site.

Can you build in an LTI counter?

We can. A lost-time-injury counter -- the "365 days since our last lost time injury" display you see on safety-conscious sites -- can be built into the board as an electronic LED counter rather than a number someone changes by hand each morning. That means the count is always current and visible, and it becomes a feature of the board instead of a sticker that peels.

A large FMCG manufacturer asked us for exactly this: their safety board needed the LTI figure built in as an electronic display so it updated cleanly and stood out. Because we fabricate the whole board in-house, integrating an LED counter into the acrylic layout is a design job we handle rather than outsource. If you want a live counter, a QR code panel, or any other element built into the board, tell us what the site needs and we'll work out how to make it part of the one unit.

Frequently asked questions

Do you supply site notice boards across Adelaide?

Yes. We build them at our Kent Town workshop and supply construction, industrial and facilities sites right across Adelaide and regional SA. For a repeat program of boards across multiple sites, talk to us and we'll set up a consistent layout you can reorder.

Can the printed layout match our branding and safety colours?

Absolutely. The board is printed to your artwork, so your logo, site name, safety colours and layout all go on exactly as you want them. Send us your design or brief and we'll set the print up to suit.

Are the document holders a standard option I select online?

No -- the holders, sleeves and any built-in counter are custom fabrication, so they're a quick conversation rather than a checkbox. You can price the base acrylic panel online instantly, then call us to add the holders and extras your site needs.
