Longze Punched C-Channel Support Systems | Slotted Steel Profiles | Professional Solar Fastener Manufacturer

Product Summary

Longze U Slotted Steel Strut Channels are the industry standard for modular framing and solar racking support. Available in high-strength Carbon Steel (HDG) or lightweight Aluminum Alloy 6005-T5,

our Slotted Steel Profiles feature precision-engineered hole patterns that allow for rapid, infinite adjustment and secure fastening in complex structural assemblies.

• ✔ Versatile Strut Design: The internal flange design provides superior grip for channel nuts, making it the ideal C-Channel foundation for electrical, mechanical, and PV solar racking.
  
  

• ✔ Precision Slotted Patterns: Standardized slots ensure compatibility with all international Strut Channel accessories, enabling tool-free alignment and fast installation.
  
  

• ✔ High-Load Stability: Engineered to resist torsional stress and vertical deflection, supporting heavy-duty conduits, piping, and photovoltaic module arrays.

• Standards: DIN 6923, ISO 4161, ASME B18.16.4.
  
  

• Material: Q235B Carbon Steel / Aluminum Alloy 6005-T5.
  
  

• Surface Finish: Hot-Dip Galvanized (65μm+) / Clear Anodized (12μm+) / Powder Coated.
  
  

• Application: Solar Racking Supports, Industrial Pipe Racks, Electrical Cable Tray Framing.
