LTA PUB HDB DIC Galvanized Steel Walkway Grating for City Road Airport Railway House
Galvanized Steel Walkway Grating s the product in accordance with customers requirements that is lined by load flat steel and horizontal rod alternately in a certain space, welded into primary plate in the high voltage resistance welding machine, then through the deep-processing of such working procedures as cutting, slitting, tapping, bordure, etc.
Standard welded steel bar grating is resistance welded to create a rugged, one-piece constructed panel, the bearing bars are automatically resistance welded at the contact point with the cross bars and, under a combination of high heat and pressure, are fused together to form a permanent joint, the cross bars provide a high degree of rigidity, yet retain a smooth flat surface for free and easy walking.

Series 3 grating is mainly used in the mining industry as it minimises the build-up of spillages on the flooring. The openings let small matter fall through while larger matter is caught on the grating. Series 3 is a very lightweight design and is not recommended for high-impact load.
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.
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.
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.
Specifications: More specifications and sizes optional for meeting various environment, load, span, sizes and shapes.
Steel grating untreated: Allowing quicker delivery to customers whom fabricate and galvanize the grating on their own.
