400mmW X1000mmL Hinged Grating 2 Pannel without Chequer Plate
Description:
Galvanized Steel Walkway Grating is 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.
Galvanized Steel Walkway Grating has strong impact resistance, strong corrosion resistance and heavy load capacity, elegant and beautiful, and has excellent performance in municipal subgrade and steel platform construction projects. The high cost performance is the construction project of the hot galvanized steel lattice plate widely used in the pavement of the old and new subgrade.
It has long service life is, it is generally within the range of 40 years -50 years. The hot-dip galvanized steel plate is a very good steel frame structure and bearing platform without the participation of the destructive factors.

Specific application:
Steel grating products are designed and manufactured for various industrial and civil constructions in city road, gardens, yard, airport, railway and industrial engineering, and they offer the following the features:
Features:
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.

| Castings<6mm | 60 | 430 | 70 | 505 |
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.
Surface Treatment:
Steel grating untreated: Allowing quicker delivery to customers whom fabricate and galvanize the grating on their own.
