Pre Galvanized Iron C-shaped Channel Steel 41x41 & 41x21 Sizes High Strength Anti-Corrosion Customizable
Core Parameters (Common Specifications)
Material: Q235B (Mainstream) / Q345
Wall Thickness: 1.5mm / 2.0mm / 2.5mm (Customizable 1.0 - 3.0mm)
Surface: Hot-dip Galvanized (≥80μm, Salt Spray Resistance 1000h+), Electro-galvanized, Powder-coated
Length: 3m / 6m (Customizable 1 - 12m)
Hole Type: Long Round Hole (14×28mm), Adjustable Hole Spacing
Theoretical Weight: 1.5mm ≈ 1.6kg/m; 2.0mm ≈ 2.1kg/m; 2.5mm ≈ 2.6kg/m
Production Process
Cold-formed bending: Continuous roller pressing of steel strips, with a tolerance of ±0.3mm and a straightness of ≤1.5mm/m
Square corner design: Different from rounded corners, it offers higher bending stiffness and tighter joint fit
Internal sawtooth: Enhances bolt engagement, prevents slippage and resists shearing
Main Applications
Photovoltaic support: Main beams and struts for distributed photovoltaic rooftops and ground-mounted power stations
Cable trays: Specialized C-shaped steel for 41×21 cable trays, used for supports and hangers
Seismic supports: Main components of seismic supports and hangers for mechanical and electrical pipelines (air ducts, water pipes, and cable trays)
Building curtain walls: Secondary beams, connectors, and column covers
Equipment bases: Small equipment frames, shelves, and maintenance platforms
The 41×21 angle Metal Strut Channel is an ideal type of material for lightweight, high-strength, quick-installation, anti-corrosion, and cost-effective applications. It is particularly suitable for three major scenarios: photovoltaic systems, cable trays, and seismic supports. Replacing traditional angle steel or channel steel with this type of material can significantly reduce costs, increase efficiency, and extend the lifespan.
