Product Title
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.

Avoid Pitfalls:
Profile Deformation: Avoid using "Mill Finish" or light-gauge (under 1.5mm) steel for main structural supports. Inadequate wall thickness will lead to channel "opening" under high torque from DIN 6923 nuts.
Corrosion Under-protection: Standard electro-zinc plating (5μm) will rust within 6 months outdoors. Always specify HDG (65μm+) o Anodized AL 6005-T5 for photovoltaic applications.
Slot Misalignment: Ensure the slot pattern is CNC-punched. Burrs in the slots can prevent channel nuts from seating properly, leading to hardware slippage during high wind events.
Perfect Fit Assembly:
Channel Nut Security: Always use serrated channel nuts that match the internal flange of the Strut Channel to ensure a vibration-proof mechanical lock.
Sequential Tightening: When building H-frames or multi-tier racks, tighten all DIN 6923 flange nuts to the specified torque (18-22 N.m) to ensure uniform load distribution across the Acero ranurado en U.
Quality Control & Logistics:
ISO 9001 Certified: 5-step QC including Anodizing/Galvanizing Thickness Gauge, Webster/Brinell Hardness Testing, y Straightness Verification.
Global Shipping: Packed in high-strength bundles with edge protectors. Optimized for container export from our Yongnian fastener and steel manufacturing hub.
Q: Can you provide back-to-back welded channels? A: Yes, we provide customized Strut Channel configurations, including back-to-back, side-to-side, and custom-punched profiles.
Q: Do your profiles match standard international accessories? A: Absolutely. Our Acero ranurado en U is designed to be 100% compatible with global strut nuts, clamps, and brackets.
