The core innovation of this product is the plug-in assembly structure, which connects bearing flat bars and cross bars via slotting and inserting, eliminating the need for resistance welding during production and avoiding structural deformation caused by high-temperature welding. The polyester spray coating provides additional color customization and anti-corrosion protection, while the thicker bearing flat bar (8mm) improves the load-bearing capacity to Class D level. The closed grid design reduces noise generated by pedestrian and vehicle passing, with a sound insulation coefficient of ≥25dB, making it suitable for noise-sensitive working environments.
The bearing flat bar has a height of 60mm and thickness of 8mm, with cross bars made of square steel with 12mm side length. The grid opening size is 60×120mm, and the standard panel size ranges from 1.5 ㎡ to 15 ㎡ per piece. The unit weight is 28.1kg per square meter, meeting the Class D heavy load requirements. It complies with the heavy duty steel grating standard GB/T 38512.
This composite plug-in steel grating is mainly used in heavy logistics loading platforms, large industrial factory floors, airport walkways, and freight yard access roads. It is suitable for scenarios with heavy vehicle and high pedestrian traffic, providing stable and quiet working and walking surfaces.
