Bayan Signage fabricates overhead gantry signs and cantilever signs for industrial estates, ports, logistics parks, community entrances and mall ring roads. Our draftsmen prepare the shop drawings, our frame shop welds the galvanised steelwork, and our own crews lift it into place, with a 5-year warranty on structure and powder coat.
A gantry sign carries direction panels above the traffic lanes on a steel truss supported at both ends, while a cantilever sign reaches over one or two lanes from a single column. Both put the message where drivers can read it over the vehicles in front. We build them for private road networks that need lane-by-lane direction: port and free-zone gates, industrial estate spines, airport service roads, master community entrances and large retail ring roads.
Once a sign spans a road, the panel is the easy part. The truss has to resist wind on a large flat face, the foundation has to resist overturning in soil that may be saline or reclaimed, the connections have to allow for steel and aluminium expanding in 50 °C sun, and the clearance has to survive future resurfacing. We detail the panels and steelwork together, fabricate the steel in our own frame shop and trial-fit the panels in the factory before anything goes to site.
Bayan Signage is the production arm of Bayan Advertising, with 15 years in the UAE market, and our factory in Industrial Area 2, Ajman has fabricated galvanised steel frames for pylons, totems and large sign structures since 2016. One project manager takes a gantry from survey through drawings, approvals, fabrication and the night lift.

The road layout usually chooses the structure for you. These are the types we fabricate, with the related signs that often go with them.
A truss across the whole carriageway on two columns, carrying a panel over each lane. The right answer for multi-lane gates and roads where every lane leads somewhere different.
View details →A single column with an arm over one or two lanes, for narrower roads or sites with room for only one foundation, which is made larger to resist overturning.
View details →A frame over a single gate or entry lane that carries the site name, the height limit and the gate number, often paired with an entrance monument.
View details →A light frame ahead of a canopy or car park entry that carries the headroom sign and warns tall vehicles before they commit to the route.
View details →Large reflective gate and lane numbers for ports and logistics hubs, mounted on the gantry itself or on the canopy above each lane.
View details →New reflective panels for existing structures when destinations change or the sheeting has aged, made to the original fixing positions.
View details →We measure lane widths, verges and medians, record the tallest regular vehicle, and confirm the foundation and structural requirements for each column position with your project team or main contractor. The survey is free in Dubai, Sharjah and Ajman.
Panel size is fixed with the structure, not after it. Our designers keep each lane to one or two destinations, and our draftsmen produce shop drawings for the structural review and the approvals.
Truss chords, diagonals, columns and base plates are cut and welded in our frame shop from galvanised sections, with every weld treated and connection holes set out from the approved drawings.
Aluminium planks are faced with reflective sheeting and lettered, then bolted to the truss on the factory floor, so clashes and misaligned holes are found in Ajman rather than on a crane at night.
We make a steel anchor bolt template in our factory so the bolts set into each foundation match our base plates exactly, then check levels and bolt positions on site before any steel goes up.
Columns are erected and plumbed, the pre-assembled truss is lifted during an agreed road closure, bolts are tightened to the specified values, and the as-built clearance is measured and recorded before the road reopens.
Every overhead structure is designed for its own span, panel area and site, so these are starting points rather than fixed values. The structural calculations and the approved drawings always govern.
| Component | Our standard | Upgrade options | Why it matters |
|---|---|---|---|
| Panels | Extruded aluminium planks, bolted | Deeper planks for wide multi-destination panels | Planks join into flat panels several metres wide and can be replaced one by one later. |
| Sheeting | High intensity prismatic | Full-cube microprismatic | Overhead panels are read at an angle and at distance, where higher grades return far more light. |
| Truss or arm | Galvanised steel lattice or box section | Powder coat over galvanising for colour | Sized for wind on the panels and self-weight, with a small camber so the span never appears to sag. |
| Connections | Slotted panel clamps, galvanised bolts | Stainless fixings on coastal sites | Slots allow alignment on site and thermal movement between hot days and cooler nights. |
| Columns | Galvanised tubular or box columns on base plates | Crash barrier protection at the roadside | A column close to traffic needs a barrier so a vehicle strike does not become a structural failure. |
| Foundations | Reinforced concrete pads with cast-in anchor bolts | Piled foundations for poor or reclaimed ground | Coastal and reclaimed soils often change the design, which is why soil data comes first. |
Gantry projects are won or lost before the steel is ordered. These are the decisions we ask clients to settle first.
Vertical clearance under the lowest point drives the column height, the lift and sometimes the approvals. On roads it is commonly around 5.5 m or more; port and industrial sites with cranes, reach stackers or oversized loads may need much more. Ask what the tallest regular vehicle is, add a margin for one or two future resurfacing layers, and only then start drawing.
Panel area drives wind load, and wind load sizes the truss, the columns and the foundations. Adding a third destination to a lane panel can push the whole structure up a section size. Keep overhead panels to one or two destinations per lane and move secondary names to roadside signs, which are far cheaper to enlarge.
On reclaimed land, near the coast or where the water table is high, the ground decides how large each foundation must be, and a long span or a cantilever can change the answer. We confirm the foundation and structural requirements with your project team or main contractor at the survey stage, so the base plates and anchor bolt templates we fabricate match what is built on site.
Lifting a truss usually needs a crane, an agreed road closure and a traffic management arrangement, typically at night or over a weekend. On live estates and ports those windows are scarce. We fix the lift date at the start of the job and programme backwards to fabrication and site readiness, so the structure is ready when the window opens.
A cantilever looks simpler because it has one column, but that single foundation resists the whole overturning load and is usually much larger than either gantry foundation. Where both verges have room, a full-span gantry is often more economical above two lanes, and it gives every lane its own panel.
Overhead structures are priced from the survey, the message and the structure, never from a list. Send us the road layout, lane widths, the destinations for each lane and any known site constraints, and we will return an itemised quote, usually within 24 hours, separating design, steel, panels, approvals and installation.
Longer spans need deeper trusses and heavier steel. A cantilever saves one foundation but needs a larger one to resist overturning.
Panel area sets the wind load, which sizes the truss, the columns and the foundations. A modestly larger panel can mean a noticeably heavier structure.
Ground conditions, buried services and tight verges affect column positions and base plate sizes, which we confirm with your project team or main contractor at the survey.
Shop drawings, the structural review and developer or authority approvals are part of the scope and take time before fabrication can start.
Galvanised steel is the standard. A powder-coat colour over the galvanising, to match a brand or community palette, adds cost and finishing time.
Cranes, traffic management and night closures are planned and approved in advance, and their cost depends heavily on the site and the window available.
Overhead signs on public roads belong to the road authority's network, such as RTA in Dubai, and are normally designed and installed through approved contractors to its specification. On private estates, ports, free zones and master communities, the developer or free-zone authority, for example JAFZA or a community master developer, usually approves the structure, often with the municipality involved where a structural permit applies.
Our draftsmen prepare the shop drawings, general arrangement and panel layouts for the submission, and foundation and structural requirements are confirmed with your project team or main contractor at the survey stage. Requirements vary with location and with whether the road connects to a public one, so we confirm the approvals for your exact site before the design is finalised.
Truss, columns, base plates and reflective panels are all fabricated at our Ajman factory, so structure and sign follow the same drawings. Visits during fabrication are welcome.
Panels are bolted to the steel on our factory floor, so fit problems are solved in Ajman rather than on a crane during a road closure.
Our technical draftsmen produce shop drawings and submission packages for developers, free zones and municipalities, with one project manager following them through.
Overhead structures and panels are covered for 5 years on structure and powder coat, with the warranty document issued at handover.
Design, steel, panels, foundations and installation are priced as separate lines, usually within 24 hours, so engineers and clients can compare offers fairly.
More than 500 clients across the UAE, including national retail groups and international brands, with most of our work coming from repeat clients and referrals.
It depends on the span, the panel area, the soil and foundations, the finish and the lift arrangements. A short cantilever over one lane on good ground costs a fraction of a full-span gantry over a four-lane port gate. Send us the road layout and the message for each lane, and we will send an itemised quote, usually within 24 hours.
A gantry sign spans the whole road on two supports, one each side, and can carry a panel over every lane. A cantilever sign has one support at the roadside with an arm reaching over one or two lanes. Gantries suit wide multi-lane roads; cantilevers suit narrower roads or sites with space on only one side.
Yes, always. An overhead sign is a structure that must resist wind, its own weight and, on roads, the risk of vehicle impact. The structural and foundation requirements are confirmed with your project team or main contractor at the survey stage, and our shop drawings reflect them, together with the relevant developer or authority approvals, before fabrication starts.
On roads, clearance is commonly around 5.5 m or more, but the exact figure comes from the authority or project specification and can be higher on routes used by oversized loads. On private sites we start from the tallest regular vehicle and add a margin, including an allowance for future resurfacing.
Overhead signs on public roads are part of the road authority's network and are normally delivered through approved contractors to its specification. We fabricate gantry and cantilever structures for private estates, ports, free zones, communities and campuses, and we confirm the requirement for your site before design or pricing starts.
Design and approvals often take longer than fabrication. Once drawings are approved, fabrication and trial assembly in our factory run while the site is prepared, and the lift is scheduled around an approved road closure. We give you a realistic schedule with the quote and update it after the survey.
Most modern overhead signs rely on microprismatic sheeting rather than lighting, because it reads well in headlights and avoids maintaining lamps at height. Lighting may still be specified on unlit roads with complex junctions. The specification for the road or site decides, and we can supply either approach.
Yes. The aluminium panels are bolted to the structure, so they can be replaced when destinations change or the sheeting ages. Because the structure is designed for a given panel area, a larger replacement panel should be checked against the original calculations first. We keep the drawings for every structure we build.
