Bayan Signage designs and welds the galvanised steel frames that hold rooftop signboards, building letters, pylons and large facade signs. Our draftsmen size each frame for the wind on your roof, our welders build it in our Ajman factory and our crews fix it to the slab. Frames supplied with our outdoor signs carry the 5-year structural warranty.
A steel structure for signboards is the welded skeleton that holds a sign face, a set of letters or a lightbox clear of the building and stops the wind pushing it over. On a flat roof it is usually a row of hollow-section posts with rails across the front and diagonal bracing behind; on a facade it may be an outrigger or a ladder frame hidden behind the parapet. Building owners, contractors, retailers and sign buyers need one whenever the wall or roof cannot carry the sign by itself.
Nobody photographs the frame, yet it decides whether a big sign is still straight, dry and safe in ten years. The common failures we are called to are predictable: base plates rusting where water sits, hollow sections filling with condensation, anchors drilled into screed instead of slab, and frames copied from a smaller job without any wind check. We design against each of those on the drawing, then weld and protect the steel under our own roof rather than buying it in from a workshop we cannot inspect.
Bayan Signage has fabricated signs and their structures at Alam Square, Industrial Area 2, Ajman since 2016, as the production arm of Bayan Advertising, a UAE group with 15 years in the market. Galvanised steel frame welding for pylons, totems and wall structures is one of our core trades. Our draftsmen produce the structural plans for authority submissions, and the crew that welds the frame is the crew that bolts it to your roof.

The fixing method and the sign it carries set the shape of the frame. These are the structures we weld most often in our Ajman factory.

We record the slab, beams and parapet, check the waterproofing and drainage, measure the sign zone and note access for lifting. Where drawings of the building exist, we ask for them. The survey is free in Dubai, Sharjah and Ajman.
Our draftsmen set the frame geometry from the sign face, its height above the roof and the wind exposure, then draw member sizes, connections, base plates and anchors for fabrication and the authority submission.
Hollow sections are cut to length and base plates, gussets and brackets are laser-cut from mild steel, so bolt holes line up exactly with the anchors set out on the roof.
Frames are welded in sections sized for the lift, then trial-assembled in the factory. Hollow sections are sealed or given drain holes so water cannot sit inside the steel.
Welds and cut ends are cleaned and treated with zinc-rich primer before paint or powder coat. Each frame is inspected against the drawing for dimensions, welds and finish before dispatch.
Once the plinths or slab agreed at survey are ready, our crew fixes the anchors, lifts and plumbs the frame, torques every bolt and restores the waterproofing around each penetration before the sign face goes on.
Member sizes always come from the load design for your sign, so the table shows the build-up rather than fixed sizes. Every upgrade is priced as its own line.
| Element | Our standard | Upgrade options | Why it matters |
|---|---|---|---|
| Main posts | Galvanised SHS or RHS sized to the wind calculation | Heavier sections or extra posts for exposed towers | Posts take the bending from the wind and carry it down to the base. |
| Face rails | Hollow-section rails at centres set by the face | Aluminium rails where weight must be saved | Correct spacing gives a flat plane so panels and letters do not ripple. |
| Bracing | Diagonal back struts and cross bracing | Moment frames where bracing would block access | Bracing turns a tall, flexible frame into a stiff triangle and keeps post sizes sensible. |
| Base plates and anchors | Laser-cut plates with chemical anchors into concrete | Bolted to steel beams, or a ballasted base | Anchors must reach structural concrete, not screed, with the embedment the design calls for. |
| Corrosion protection | Galvanised steel, zinc-rich primer on welds, paint or powder coat | Heavier zinc coating and duplex paint for coastal roofs | Rust starts at welds, cut ends and base plates, so those get the most attention. |
| Fasteners | Galvanised bolts with washers | Stainless bolts with isolation washers | Isolation stops galvanic corrosion where stainless meets galvanised steel or aluminium. |
| Access | Fixing points for safe maintenance | Grating walkway, handrails, caged ladder | A built-in walkway makes every lamp change cheaper and safer than hiring a crane. |
Most frame problems we are asked to fix were decided before the first weld. These are the points we raise at the start of every structural job.
Wind almost always governs. As a rough illustration, a modest design pressure of 1 kN per square metre puts about 36 kN on a 12 m by 3 m face. If the centre of that face is 3 m above the roof, the overturning moment is around 108 kN m, and the frame, the anchors and the slab all have to resist it with a margin. Height and open ground can double or triple the pressure, and corners are worse again.
Before we size a single post we want the slab thickness, beam positions, screed depth and the type of waterproofing. A frame anchored into 80 mm of screed above the slab is not anchored at all. If the roof carries a waterproofing warranty, the roofing contractor often needs to approve the detail around each plinth, so we bring them in early rather than after the drilling.
Ballasted frames avoid drilling a new roof, which landlords like, but the blocks must outweigh the overturning effect with a safety margin, and on a big sign that can mean several tonnes of concrete. The slab must be checked for that load. On older roofs or lightweight decks, an anchored frame down to the main beams is often the safer and cheaper answer.
We keep the bottom of the sign face roughly 300 to 600 mm above the roof so water drains and the roof can be cleaned under it. For anything above head height, a walkway with handrails behind the face lets a technician change a driver from the frame. Adding a walkway on the drawing costs a fraction of retrofitting one or booking a crane every time a light fails.
When we survey an existing rooftop sign, we start at the base plates, where water collects and rust spreads unseen under paint. Then we check inside hollow sections for trapped water and the welds at post heads. Corroded members can usually be cut out, replaced and re-protected, which often costs much less than a new structure, but only after the remaining steel is confirmed sound.
Every frame is priced from its drawing, so we do not publish a rate per tonne. Send the sign size, the building address and photos of the roof or wall, and we return an itemised quote, usually within 24 hours.
Larger faces on taller, open sites need heavier sections, more bracing and bigger anchors. Steel weight rises faster than face area once a sign gets large.
Anchored frames need plinths, drilling and re-waterproofing; ballasted frames need concrete blocks lifted to the roof. Each route carries its own labour and lifting cost.
Galvanised steel with primer and paint suits most inland sites. A heavier zinc coat, duplex paint or stainless fasteners for coastal roofs cost more and last longer.
Walkways, handrails, ladders and fall-arrest points add steel and fabrication hours, but cut the cost and risk of every future maintenance visit.
A crane, a long crane booking or a manual lift up a stair core changes the installation cost considerably, as do night-only working hours.
Structural plans, authority submissions and any consultant review of the roof loads are prepared and listed separately on the quote.
Rooftop signs and their structures usually need approval from Dubai Municipality, Sharjah Municipality or Ajman Municipality, or from the free-zone authority, such as JAFZA, DMCC or TECOM, where the building sits in their area. Authorities commonly ask for structural drawings with the application, and the building owner or original consultant may want to review new loads on the roof.
Our technical draftsmen prepare the elevation, structural plan, member schedule and fixing details for the submission and follow it through. Where an authority asks for additional structural documents, we flag it at the start and agree with your project team or main contractor how it is covered in the programme. Requirements differ between emirates and change over time, so we confirm what applies to your building at the survey.
Galvanised steel frame welding, laser-cut plates and powder coating happen at our Ajman factory, so we control every weld and every primed edge.
The same team designs the face, the letters and the frame behind them, so fixing points, cable routes and access are planned as one.
Frames supplied with our outdoor signs are covered for 5 years on structure, alongside LEDs and powder coat.
Our technical draftsmen prepare structural plans and submissions for municipalities and free-zone authorities across the UAE.
Installation crews trained for high access and site safety lift, fix and seal the frame, then fit the sign on the same programme.
Steel, protection, lifting, installation and permit work appear as separate lines, so a contractor or building owner can compare like for like.
It depends on the sign size, the height and exposure of the building, the fixing method, the corrosion protection and the lifting needed. A small frame on a two-storey roof costs a fraction of a braced structure for a tower. Send us the sign size, address and roof photos and we will send an itemised quote, usually within 24 hours.
There is no standard answer, which is why copying a frame from another job is risky. Member sizes come from the wind load on your sign face, its height above the roof and the exposure of the site. Our draftsmen size the posts, bracing, base plates and anchors for your building and show them on the structural drawing.
Usually, yes. Rooftop signs and their structures normally need municipality or free-zone approval, and authorities often ask for structural drawings with the application. The building owner may also need to consent to new loads on the roof. We prepare the drawings and confirm the current requirement for your location.
Yes, with a ballasted frame that sits on protection pads and is held down by concrete blocks. It avoids penetrating new waterproofing, but the ballast for a large sign can weigh several tonnes, so the roof slab must be checked for that load first. Where the slab cannot take it, an anchored frame is the safer choice.
A well-protected frame typically lasts many years, but life depends on detailing as much as on the coating. Water sitting on base plates, condensation inside hollow sections and unprotected welds are what shorten it. We prime welds and cut ends, seal or drain sections, and recommend a heavier coating system for coastal roofs.
For large rooftop and pylon structures, galvanised steel is usually the right choice because it is stiffer and stronger for its cost. Aluminium is lighter and does not rust, so we use it for fascia sub-frames, face rails and smaller signs where weight matters more than span. Many signs combine both, with isolation between the metals.
Often, yes. We survey the frame from the base plates up, cut out and replace corroded members, add bracing where it is missing and re-protect the steel before a new face goes on. If the remaining steel is not sound, we tell you plainly and quote a replacement. Our sign removal and relocation team handles old structures that must come down.
Yes. We weld frames in Ajman and install them across all seven emirates, including Abu Dhabi, Ras Al Khaimah, Umm Al Quwain and Fujairah. The site survey is free in Dubai, Sharjah and Ajman.
