Hanxing DC-W750 Corrugated Roofing Sheet

The Hanxing DC-W750 corrugated roofing sheet is a profiled color-coated steel roofing panel specially developed for industrial buildings, warehouses, logistics centers, and large-span structures. It corresponds to the standard industry profile YX35-125-750 and is manufactured using fully automated CNC roll forming equipment, ensuring high dimensional accuracy, uniform profile shape, and stable structural performance.

This roofing sheet combines excellent structural strength, efficient drainage capability, and reliable corrosion resistance. It can be used as a standalone lightweight roofing solution or integrated with insulation materials such as glass wool, vapor barriers, and steel mesh to form a complete thermal insulation roofing system. It is suitable for both new construction and renovation projects across various climate conditions.

3. Structural Features and Mechanical Performance

The Hanxing DC-W750 roofing sheet adopts a trapezoidal high rib profile, offering higher moment of inertia and bending resistance compared to low-profile roofing sheets. This allows for larger purlin spacing and reduces the amount of supporting steel structure required.

• 35 mm wave height creates continuous and efficient drainage channels preventing water accumulation

• High rigidity profile provides excellent resistance to bending deformation and structural loads

• Strong panel integrity minimizes risks of deflection warping or bulging after installation

• Side overlap adopts one wave interlocking design ensuring tight connection and good sealing performance

• Lightweight structure reduces load on the main steel structure and lowers overall construction cost

• Non-combustible metal material with Class A fire rating meets basic building fire safety requirements

4. Waterproof and Weather Resistance Performance

As a roofing enclosure material, the Hanxing DC-W750 corrugated roofing sheet delivers reliable waterproofing and weather resistance under various environmental conditions including rain wind and strong sunlight.

• Longitudinal installation along slope with sufficient overlap effectively prevents water penetration

• Fasteners installed at wave crest combined with waterproof washers reduce leakage risk at fixing points

• Dual protection from metallic coating and surface paint provides strong anti-corrosion performance

• Suitable for long-term use in inland environments without rust or perforation issues

• For coastal or chemical environments galvalume base combined with PVDF coating is recommended for enhanced durability

• Stable dimensional performance under temperature changes reducing risks of cracking or deformation
