As specialist steel manufacturers, we are able to supply a wide range of high-performance Decking Beams suitable for a variety of slab and shear wall formwork systems. The Decking Beams we supply offer a popular alternative to traditional timber squares for the construction industry. Like all of our beams, these steel decking beams have a unique telescopic length extension facility to cater for all different room sizes. The beams have a solid 2.75mm wall for maximum stability during the formwork process and a ‘fair-faced’ finish to the finished slab surface.

Features
■ Telescopic & Extendable Design
Our decking beam system comes complete with an internal connector, which allows the system to be extended to any length and connected to other systems. The connectors allow beams to be exactly sized to the building opening without the need for on-site cutting or welding.
■ Superior Load-Bearing Performance
Our standard framing is typically 100 x 60mm or 110 x 75mm with a 2.75mm wall thickness, giving exceptional bending and torsional strength, allowing walls and floors to be built to “no-plastering” and with a perfectly flat finish.
■ "Steel-Instead-of-Wood" Efficiency
Our steel decking beams can save up to 40% in labour costs by simplifying the building process through easy-to-erect, handle, and strip modular components that don't require professional carpentry skills.
■ Durable Surface Treatment
These parts are available in high-visibility blue or in a galvanized finish and can be modified to meet your unique needs. Our coating finish resists both the harsh alkaline environment of the concrete it is being inserted into and the harsh outdoor environment. Because of this, the parts will remain rust-free for hundreds of uses.
Applications
- Concrete Slab Formwork (Decking Support)
- Shear Wall and Column Reinforcement
- Tunnel and Bridge Construction
- Industrial and Residential Infrastructure Projects
FAQ
What are the primary advantages of your Steel Decking Beam compared to traditional timber beams?
Our steel decking beams offer significantly higher load-bearing capacity and a much longer lifespan (300+ cycles). Unlike timber, steel beams do not warp, crack, or rot. This ensures higher precision in concrete pouring, leading to a "fair-faced" finish that eliminates the need for expensive secondary plastering.
Does the 2.75mm thickness apply to all dimensions?
Yes, we strictly maintain a 2.75mm real thickness for our standard 3000mm, 2000mm, and 1500mm models. This thickness is the "golden standard" in the industry, balancing structural safety with ease of handling on-site.
How does the extendable/telescopic mechanism work?
Each beam is designed to work with our specialized internal connector. This connector slides into the profile of two beams, allowing them to be joined seamlessly. It provides flexibility to adjust the total length to fit any room span or wall width precisely, reducing the need for custom-sized beams.
