High Loading Strength Black Steel Bar Grating, Grating Steel for Airfields, Industrial Plants, Truck and Bus terminals

Welded galvanized grating. The cross bars are welded onto bearing bars with the high pressure resistance welding machine and then cutting, banding, surface treatment.
Press-locked galvanized grating. The cross bars are pressure locked onto the bearing bars with grooving and then welding and hot dipped galvanizing.
Features & Characteristics

High strength. The strength and the toughness are much higher than cast iron. Can be used for terminals, airport and other large-span and heavy loading condition.
Hot-dip galvanized treatment. Good rust-proof property, maintenance-free replacement.
Anti-theft design. The cover and the frame is joint with hinge offering security, safety and open convenience.
Savings investments. Large-span. Less lost for heavy load compared with cast iron products. Cost can be saved for the risk of being stolen or crushing one if cast iron is uses.
Aesthetic outlook. Simple lines and silver appearance meeting the modern trend.
The best drainage. Leakage area of 83.3 percent, more than twice of cast iron products.
Applications

Galvanized grating are designed and manufactured for various industrial and civil constructions in city road, gardens, yard, airport, railway and industrial engineering.
