Leading the metal structure industry with high-load capacity, corrosion-resistant drainage solutions and bespoke industrial steel grating.
Defining the gold standard for heavy-duty industrial gratings.
◆ As a global leader in the gully grid market, we specialize in the manufacturing of high-performance metal structures. Our HEAVY-DUTY STEEL GRATINGS are designed to withstand extreme pressure while ensuring optimal drainage efficiency for urban and industrial infrastructure.
◆ Our gully grid production incorporates HOT-DIP GALVANIZATION and precision laser cutting. By combining metallurgical excellence with structural analysis, we provide solutions that eliminate deformation and resist chemical corrosion in the harshest environments.
Three fundamental pillars ensuring the longevity of our metal structures.
Engineering the highest stability for heavy traffic zones.
Advanced chemical barriers for long-term outdoor durability.
Zero-tolerance manufacturing for seamless installation.
Data-driven validation of our gully grid engineering superiority.
Detailed measurements for standard gully grid configurations.

Depending on the environment, our hot-dip galvanized gully grid systems typically last between 15 to 25 years, with stainless steel options extending up to 40 years in corrosive areas.
Yes, we offer full customization including bespoke lengths, widths, and load-bearing specifications using precision CNC laser cutting technology.
We use serrated bar profiles and specialized surface texturing that increase friction, ensuring safety for pedestrians and vehicles even in wet conditions.
For coastal regions, we strongly recommend Stainless Steel 316L or high-grade Titanium alloys due to their superior resistance to chloride-induced corrosion.
Yes, every shipment includes a detailed technical manual and installation guide to ensure the grid is perfectly seated and locked.
Standard bulk orders typically ship within 15-30 days, depending on the complexity of the customization and the material grade selected.
