Bayan Signage welds, laser cuts, powder-coats and installs galvanised and mild steel sign boards for construction sites, yards, plant gates, farms and feature walls across the UAE. Frames are welded in our Ajman factory, every coating system is chosen for its exposure, and outdoor steel signs carry our 5-year warranty on finish and structure.
A steel sign board is the toughest flat sign we make: a galvanised or mild steel face on a welded frame, bolted to posts, fences or hoarding. Galvanised steel, often called GI sheet, is mild steel coated with zinc for rust protection. Mild steel without zinc is cheaper and welds more easily, but rusts quickly outdoors unless fully coated. Both suit contractors, logistics yards, quarries, farms and industrial plants, and mild steel is also the base for laser-cut feature signs in restaurants and showrooms.
Steel signs fail at their weakest point, which is rarely the face. Welds burn off zinc, drilled holes and cut edges expose bare steel, paint flakes off fresh galvanising without the right pre-treatment, and zinc-plated bolts rust long before the board. In our Ajman factory we treat every weld, edge and hole with zinc-rich paint, pre-treat before powder coating, specify galvanised or stainless bolts and size frames and posts for the real weight. A 2,400 by 1,200 mm board in 2 mm steel weighs around 45 kg before its frame.
Bayan Signage is the production arm of Bayan Advertising, which has 15 years in the UAE, and we have run our factory at Alam Square, Industrial Area 2, Ajman, since 2016. Galvanised steel frame welding for pylons, totems and wall structures is core work for us, so steel sign boards come from the same welders, laser cutters and powder coating line as our largest structures.

Most steel work falls into one of these groups. We choose galvanised or mild steel by exposure, and aluminium where weight or salt air is the main issue.

We check the wall, fence or ground, measure the position and note wind exposure and traffic. Fence-mounted boards need the fence itself checked for the extra wind area. The survey is free in Dubai, Sharjah and Ajman.
Draftsmen detail sheet gauge, frame section, post size, base plates and foundations, plus the coating system, so the drawing works for fabrication and any approval submission.
Faces and cut-out lettering are laser-cut; frames are cut and welded from galvanised sections in our workshop. Welds are ground and every weld, edge and hole is treated with zinc-rich paint.
Steel is cleaned and pre-treated so powder bonds to the zinc, then powder-coated in-house to your RAL colour. Graphics are applied or laminated panels riveted on.
Each board is checked against the approved artwork for size, colour and text, and the coating is inspected at edges and fixing points before dispatch.
Our crew sets posts in concrete or bolts base plates, fixes the board with galvanised or stainless bolts and plans lifting for heavy boards, then hands over the warranty document.
This is our usual specification for a permanent outdoor steel board. Short-term site boards can be lighter, and every change is itemised.
| Component | Our standard | Upgrade options | Why it matters |
|---|---|---|---|
| Face | 1.5 to 2 mm pre-galvanised sheet | 3 mm mild steel for laser-cut panels | Thicker sheet resists denting and stays flatter when welded to a frame. |
| Frame | Welded galvanised hollow section | Hot-dip galvanised after fabrication where specified | The frame keeps large faces flat and carries the fixings. |
| Edges and welds | Zinc-rich paint on every cut, hole and weld | Full duplex system on all surfaces | Corrosion always starts where the zinc has been broken. |
| Finish | Polyester powder coat over pre-treated zinc | Two-pack paint, sealed rusted finish | Correct pre-treatment stops powder flaking off galvanised steel. |
| Graphics | Laminated vinyl or laser-cut lettering | Reflective sheeting, riveted printed panels | Laminate survives dust and pressure washing on working sites. |
| Posts and bolts | Galvanised posts, galvanised or stainless bolts | Base plates with chemical anchors | Cheap plated bolts rust first and streak the face below. |
Steel is forgiving in the workshop and unforgiving outdoors. These are the points we check on every steel brief.
Welding burns the zinc off around every joint, so a frame welded from galvanised section must have its welds treated afterwards. Where a specification calls for hot-dip galvanising after fabrication, the frame needs small vent and drain holes in every hollow section so molten zinc can flow in and out. Without them, frames come back with bare patches inside or are refused outright.
Paint and powder do not grip new galvanising well. Without the correct cleaning and pre-treatment, the coating can peel off in sheets within a year or two, taking the graphics with it. That is the most common failure we see on steel boards made elsewhere, and it is entirely preventable in the factory.
A single coat of paint on mild steel looks fine at handover and shows rust streaks after the first humid summer. For outdoor boards, use galvanised steel with powder coat on top. Plain mild steel belongs indoors, in sheltered positions, or in deliberately rusted feature signs that are sealed and detailed with a drip gap.
Steel is roughly three times as heavy as aluminium. A heavy board on a light fence or a thin block wall can pull its support down in a strong shamal. We check the support first, size posts and foundations for weight plus wind, and plan lifting on site. Near the sea, we usually suggest aluminium faces on galvanised steel frames instead.
Rusted-finish steel releases orange water when it rains or is washed, and the stain on limestone or light paving is very hard to remove. We seal rusted finishes and leave a gap and drip channel beneath them, or move the sign away from pale surfaces.
We quote each board from its drawing. Send the size, artwork, quantity and a photo of where it will go, and you receive an itemised quote for fabrication, installation and any permits, usually within 24 hours.
Steel is bought by weight. Heavier sheet and larger boards add material, handling and sometimes lifting equipment on site.
Welded frames, base plates and hollow-section posts add material and welding time. A fence-mounted board costs less than a freestanding one.
Plain galvanised is economical. Duplex powder coat, multi-coat paint and sealed rusted finishes each add preparation and coating steps.
Cut-out logos and lettering add cutting time, and fine detail in thick plate adds deburring and hand finishing.
Pre-galvanised sheet with treated welds is standard. Hot-dip galvanising after fabrication adds transport and lead time.
Excavation, concrete, a crane or forklift and work beside live traffic or operating plant all affect installation cost.
Construction site boards usually have their content, size and position set by the authority, the master developer or the main contractor's HSE plan, and boards facing public roads may need RTA or municipality approval. In free zones such as JAFZA, the zone authority normally sets its own requirements for site and yard signage.
Permanent steel signs on buildings and gates follow the same approval routes as other outdoor signs: Dubai Municipality, Sharjah or Ajman Municipality, or the relevant free zone. Our draftsmen prepare the drawings and structural details for submission. Requirements vary by location and change over time, so we confirm the current rules for your exact site.
Galvanised steel frame welding for pylons, totems and wall structures is core work in our Ajman factory, along with laser cutting and powder coating.
Outdoor steel signs carry a 5-year warranty on powder coat finish and structure, with a written warranty document handed over when the sign is installed.
Treated welds and edges, correct pre-treatment and powder coating in-house stop the peeling and rust streaks that ruin cheap boards.
Draftsmen detail posts, base plates and foundations for weight and wind, and our crews plan lifting before arriving on site.
Drawings for municipality, RTA-facing and free-zone submissions are prepared by our own technical draftsmen, who confirm the current requirement for your exact site.
Steel, coating, installation, lifting and permits are listed separately, usually within 24 hours, so you can compare like for like.
It depends on steel thickness and area, frame and posts, coating system, laser-cut detail and site work. A fence-mounted galvanised board costs far less than a large freestanding board with foundations and a crane. Send the size, artwork and a site photo, and we will send an itemised quote, usually within 24 hours.
Galvanised steel is mild steel with a zinc coating that protects it from rust. Mild steel has no coating and rusts quickly outdoors unless fully painted. Galvanised is the better choice for most outdoor signs; plain mild steel suits indoor feature signs and controlled rusted finishes.
Yes. Galvanised steel can be powder-coated in almost any RAL colour, but it needs correct pre-treatment so the coating bonds to the zinc. Done properly, zinc plus powder coat lasts much longer than either alone. Done badly, the paint starts peeling within a year.
For a heavy board on a busy site with trucks and plant moving, galvanised steel is usually better because it resists knocks and is economical in large sizes. For a lighter board, a short project or a site near the coast, aluminium is often enough and easier to move.
A 2 mm steel sheet weighs about 16 kg per square metre, so a 2,400 by 1,200 mm board is around 45 kg before its frame. With a welded frame and posts, a freestanding sign can pass 100 kg, which is why posts, foundations and lifting are planned on the drawing.
Yes. Logos, lettering and patterns are laser-cut from mild or stainless steel, then powder-coated, blackened or given a sealed rusted finish. Cut-outs can be backed with acrylic and lit with LED modules. Very fine detail in thick plate is limited by the cut width, so we check artwork before quoting.
A galvanised and powder-coated board with treated edges typically gives many years of service, and our outdoor steel signs carry a 5-year warranty on finish and structure. Within sight of the sea, steel weathers faster at edges and fixings, so we often suggest aluminium faces on steel frames there.
Yes. Our crews install across all seven emirates from our Ajman factory, including post-mounted boards with concrete foundations, fence and hoarding boards and wall-mounted signs. We coordinate access and HSE requirements with the site's main contractor.
