Product Description
When industrial safety and heavy load-bearing capacities are non-negotiable, our hot dipped galvanized steel grating is the premier choice. Constructed from high-strength Q235B or Q345B steel, this grating features a robust matrix of flat steel bars and twisted square steel, automatically pressure-welded for maximum structural integrity. The core advantage lies in its dual function: offering immense impact resistance and load-bearing strength while maintaining an open, breathable design for ventilation, heat dissipation, and natural lighting. This makes it vastly superior to ordinary wire mesh or standard steel plates in demanding industrial environments.
Our factory's surface treatment process elevates this product from standard to exceptional. After welding, the grating is immersed in a 450-460℃ molten zinc bath, creating a dense, highly adhesive zinc layer exceeding 80μm (approx. 600g/m²). This phenomenal corrosion resistance guarantees a lifespan of 20 to 50 years even in harsh, exposed outdoor environments. As a trusted partner to major state-owned infrastructure giants like China Railway and China Communications Construction Company (CCCC), we manufacture hot dipped galvanized steel grating that defines modern industrial safety, offering peace of mind for high-altitude walkways and heavy machinery platforms.

Customization & Factory Strength
Our 3,000-square-meter facility is equipped to handle complex OEM/ODM requirements. We can customize the thickness and height of the flat bars to perfectly match your specific load-bearing calculations. Our R&D team provides complete solutions, transitioning seamlessly from your CAD blueprints to finished, galvanization-ready modules, ensuring zero installation issues on-site.
Packaging & Shipping
Gratings are stacked horizontally, bound with heavy-duty steel straps, and placed on robust pallets suitable for forklift and gantry crane handling. Delivery is typically initiated within 1-2 months for standard dimensions, ensuring your construction schedule remains uninterrupted.
FAQ
Q: Do you perform 100% inspection before packing the gratings?
A: Yes, every batch undergoes a 100% visual and dimensional inspection, along with zinc coating thickness verification, prior to being cleared for packing.
Q: Can you provide a sample before I place a mass production order?
A: Yes, we can provide prototype samples. Depending on the specific specifications, samples can be arranged flexibly (free or at a nominal charge) to ensure it meets your project standards.
Q: What happens if the zinc coating or structure is damaged upon arrival?
A: We strictly honor our commitments regarding the storage and transportation phases under our responsibility. We will resolve any transit damage issues in accordance with the agreed-upon trade terms and our quality warranty.
