MR468 Corrugated Steel Roofing Sheets for Prefabricated Metal Panel System
The MR468 High-Performance Metal Prefabricated Roofing System is a premium solution designed for large-span industrial roofs exceeding 20 meters. Engineered through high-precision roll-forming of galvanized steel, aluminum-zinc coated steel, and color-coated steel sheets, it integrates advanced insulation materials and base plates into a complete, durable roofing system. Ideal for warehouses and industrial facilities requiring maximum structural integrity.

Product details
- Corrugated Roofing Panels: High-rib profile for rapid water shedding.
- Sliding Clips / Supports: High-strength structural clips designed to break thermal bridges and absorb structural movement.
- Sub-structure Compatibility: Easily installs over standard Z/C Purlins and steel Structure.
- Insulation Integration: Can be seamlessly combined with fiberglass wool, rock wool, or PU/PIR boards to form an energy-saving sandwich roof system.
Why Choose MR468 Corrugated Steel Sheets?
1. Reasonable Section Design & Material Efficiency
With an effective coverage width of 468mm and a raw material width of 600mm, the MR468 achieves a high material utilization rate of 78%. The 70mm high wave peaks (ribs) ensure superior structural rigidity and exceptional drainage performance.
2. Wind-Resistant Capacity
Say goodbye to wind-uplift issues. Our corrugated sheets feature a sophisticated interlocking seam design. Once meshed with the high-strength steel sliding clips, the entire roof becomes a single, integrated monolithic structure capable of withstanding extreme wind loads.
3. Zero-Screw Concealed Installation
Unlike traditional corrugated sheets that require exposed screws (which eventually rust and leak), the MR468 system uses a completely concealed bracket installation. Not a single screw penetrates the exterior surface, guaranteeing a 100% leak-proof lifespan.
4. Superior Water & Air Tightness
Precision molding in our factory combined with on-site automatic seam-sealing technology (pre-applied sealant) vastly improves the water and air tightness of the roof, protecting your valuable internal assets.
