41×41 Rib-Reinforced High Tensile Anti-Rust C Steel Strut Channel for Heavy-Duty Construction

Pre-Galvanized 41×41 Rib-Reinforced C Steel Strut | High Tensile Anti-Rust Custom Metal Channel

Product Overview:

This 41×41 square-edged rib-reinforced metal strut channel, also known as serrated C steel or seismic support channel, is a heavy-duty cold-rolled lightweight structural steel profile with 41mm web height and 41mm overall wing width. Featuring built-in corner reinforcing ribs, elongated oval perforations and internal serrated teeth, this upgraded profile delivers higher rigidity than standard plain C-channels, and is widely used in heavy solar PV mounting frameworks, large cable tray supports, heavy seismic bracing assemblies and comprehensive pipe gallery engineering.

Core Technical Specifications:

• Raw Material: Standard Q235B carbon steel; optional Q345 high strength grade
• Wall Thickness: Regular options 1.5mm, 2.0mm, 2.5mm; custom thickness range from 1.0mm to 3.0mm available
• Surface Anti-Corrosion Treatments: Hot dip galvanizing (zinc layer ≥80μm, salt spray testing over 1000 hours), electro-galvanization, electrostatic powder coating
• Standard Length: 3m & 6m stock lengths; custom cut lengths ranging 1m–12m supported
• Hole Format: Standard 14×28mm elongated oval holes, adjustable hole spacing upon request
• Theoretical Unit Weight:
  • 1.5mm thickness ≈ 2.0kg per meter
  • 2.0mm thickness ≈ 2.6kg per meter
  • 2.5mm thickness ≈ 3.2kg per meter

Production Manufacturing Flow:

1. 1. Cold Roll Forming: Continuous strip rolling molding process, dimensional tolerance controlled within ±0.3mm, straightness less than 1.5mm per meter
   2. Rib-Reinforced Square Edge Profile: Distinct from rounded corner channel steel, the built-in corner ribs deliver stronger bending rigidity and tighter fitting between connecting components
   3. Inner Serrated Teeth Structure: Boosts bolt clamping friction, effectively prevents fastener sliding and improves overall shear resistance

   Wide Application Fields

   1. Solar PV Mounting Systems: Main load-bearing beams and support struts for rooftop distributed solar stations and ground photovoltaic power plants
   2. Heavy Cable Tray Support: 41×41 reinforced C channel for heavy-duty cable tray hangers and main supporting frames
   3. MEP Seismic Bracing: Core structural component for heavy anti-seismic pipe hangers, suitable for ventilation ducts, water pipelines and cable tray fixing
   4. Building Curtain Wall Works: Main cross beams, connecting fittings and outer column wrapping materials
   5. Heavy Equipment Base Frames: Medium-large machinery support frames, heavy storage racks and maintenance operating platforms
