⚡ At a Glance
- • Section Profile: 41x41mm square section, 2.5mm thick, pre-galvanised mild steel, 4 metre length supplied as two pieces
- • Best for: Structural framing, fencing rails and general-purpose channel runs where corrosion resistance is useful
- • Not ideal for: Applications requiring stainless steel finish or a decorative exposed aesthetic
41x41mm plain channel made from mild steel with a 2.5mm wall and pre-galvanised coating. Supplied as two 4 metre lengths for structural and exterior-friendly use.
Strong structural support – Thanks to 2.5mm wall thickness
2.5mm wall thickness increases section stiffness and resistance to bending under typical loads for shelving and light framing. Heavy-gauge mild steel reduces deflection compared with thinner channel sections.
Reliable bracing and better load control for shelving runs, handrails and basic framing, reducing flex under load.
Lower corrosion risk – With pre-galvanised (PG) finish
Pre-galvanised coating applies a zinc layer across the surface of the mild steel to slow oxidation prior to installation. The coating protects both faces and edges during storage and handling.
Reduced need for early repainting or rust treatment, making the section suitable for damp or outdoor-exposed runs.
Fewer joins on site – Thanks to 4 metre lengths supplied as a pair
Four-metre supplied lengths allow longer continuous runs with fewer connection points, lowering the number of cuts and fixings required. Two lengths enable immediate installation of parallel runs.
Faster installation with fewer joints and less time spent aligning and fixing multiple short lengths.
