P14 Common Steel Grating Selection Guide
Grating Steel Plate Characteristics
1. Beautiful appearance: simple lines, silver appearance, modern trend;
2. Best drainage: Water leakage area of 83.3%, is more than twice that of cast iron;
3. Hot dip galvanizing: strong rust resistance, maintenance free and replacement;
4. Anti-theft design: cover and frame are connected with hinge, anti-theft, safe, easy to open;
5. Save investment: large span, heavy load, lower than the price of cast iron and save the cost of stolen or crushed replacement;
6. High strength: the strength and toughness are much higher than that of cast iron, which can be used in wharf, airport and other long-span and heavy load environment;
7. Specifications: to meet the needs of different environments, loads, spans, sizes and shapes.
Hot Dip Zinc Steel Plate Grating Usage
In metallurgy, mining, petroleum, electric power and industrial fields as well as some civil fields, the grid plate as a new building material is being increasingly widely used. The so-called new materials, in fact, have a history of more than decades abroad, but it is only in the last 10 years that they have been widely used in China. But RESEMBLE ALUMINUM-ALLOY DOOR WINDOW SAME, COMPARED WITH TRADITIONAL MATERIAL, PEOPLE STILL CALL ITS NEW MATERIAL HABITUALLY ON.
