Scaffold Beams
A scaffold beam is also called a bridging beam. They are heavy-duty horizontal bridging components in the scaffolding industry, required for large-span construction. Standard scaffold beams are made from standard O.D. 48.3mm scaffold tubes.
According to the material used in scaffold beam manufacture, the scaffold beams include steel and alloy beams.
Steel Scaffold Beams
Steel scaffold beams are made of steel. The size of the steel scaffold is OD48.3mm, and the thickness of the steel scaffold beam is 3.2mm or 4.0mm. Steel scaffold beams include steel ladder beams, and steel unit beams(lattice beams). The steel for the scaffold beam is black or galvanized steel tubes. The grade of the steel scaffold beam raw is S235 or S355 grade, which with yield strength of 235 N/mm2 and 355 N/mm2. Steel scaffold beams are the strongest scaffold beams in construction.
How Much Weight Can Steel Ladder Beams Hold?

| No. | Items | Ultimade Concentrate Load | Main Tube |
| 1 | 6.0m Ladder Beam | 43.07 KN | OD48.3×4.0mm |
| 2 | 5.0m Ladder Beam | 34.75 KN | OD48.3×3.2mm |
| 3 | 4.0 m Ladder Beam | 42.16 KN | OD48.3×3.2mm |
| 4 | 3.0m Ladder Beam | 49.54 KN | OD48.3×3.2mm |
| 5 | 1.0 m Ladder Beam | 85.67 KN | OD48.3×3.2mm |
| 7 | 10.0m Ladder Beam | 24.45 KN | OD48.3×3.2mm |
Advantages of Steel Scaffold Beams
- Strong Strength
- Cheap Cost Than Alloy
- Hot Dip Galvanized For Anti-Corrosion
- Compatible with All System Scaffold
- Meet Up Load Requirement of All Construction & Shoring Requirement
- Can Be Fixed and Connected By Standard Scaffolding Couplers and Fittings
Disadvantages of Steel Scaffold Beam
- Self-finished (black), painted and electro-galvanized steel scaffolding beams are more susceptible to rust than alloy beams
- Higher weight-to-strength ratio. Steel scaffolding beams of the same size are heavier than alloy beams
- Difficult to handle on construction sites and projects due to heavyweight
- Need to be stored indoors without rain or wet
- Requires repeated painting/maintenance over a long period
Alloy Scaffold Beams
Alloy scaffold beams are fabricated from aluminium. The size of the alloy scaffold beams includes aluminium unit beams 450mm deep, aluminium X beams 750mm deep. The aluminium grade includes 6061 T6 or 6082 T6. The size of alloy beam are with out diameter of 48.3mm, the same as the steel beam. The wall thickness is in the range of 4.5-5.0mm.
Advantages of Alloy Scaffold Beams
- Strength to Weight Ratio is Higher. Lightweight but Similar Load As Steel Scaffold Beams
- Easy to Handle At Construction & Project Site
- More Resistance To Corrosion
- Less Paint/Maintenance
- Repeat Use and Save Cost In Long Period
- Easy Transportation and Load and Unload
- Compatible with All System Scaffolds. With a Standard Out Diameter of 48.3mm
- Can be Fixed By Standard Scaffold Couplers and Clamps
Disadvantages of Alloy Scaffold Beams
- More Expensive Cost for Aluminium/Alloy Raw
- Popular Used In Lighter Load Construction & Shoring
Both alloy and steel scaffold beams are compatible with the system scaffold of ringlock, kwikstage, cuplock and tube clamp scaffolding and fixing by scaffold couplers, connectors and joints.
