The ditch cover plate, also known as the "ditch cover" or "manhole cover plate", was originally made of cement and cast iron. However, in normal use, it is easily damaged and has a high replacement cost. It is made of steel grating plates by pressure welding, which has the advantages of simple construction and installation, light weight, good bearing capacity, strong impact resistance, excellent drainage, beautiful use after hot dip galvanizing treatment on the surface of the product, rust prevention and anti-corrosion, and incomparable advantages compared to cast iron trench cover plates.
Characteristics of ditch cover plate
1. Adopting hot-dip galvanized surface treatment: with strong rust resistance.
2. Advanced cover design in China: The ditch cover made of steel grating is hinged to the frame, which is anti-theft, safe, and easy to open
3. Beautiful product appearance: simple lines, silver appearance, modern concept
4. Large mesh size provides optimal drainage: the leakage area reaches 83.3%, which is more than twice that of cast iron.
5. Material saving and investment saving: for large spans and heavy loads, the price is lower than that of cast iron; And it can save the cost of replacing the cast iron cover due to theft or crushing.
6. Adopting high-strength carbon steel, the steel grating has high strength: its strength and toughness are much higher than cast iron, and can be used in large-span and heavy-duty environments such as docks and airports.
7. Multiple product varieties: meet the needs of different environments, loads, spans, and shapes, and can provide sizes and shapes according to customers.
