Cast Iron Grating Product Features:

Noise-proof

Noiseless and environmentally compliant. This is a new requirement for the design of new-style manhole covers. The innovative five-protection manhole cover design incorporates a design concept that allows vehicles to collide with the edge of the manhole ring instead of the cover itself, preventing the entire cover from sinking. Effectively addresses the "rusted edge" issue around city manholes.

2. Anti-theft

Utilizing anti-theft design, the lock and key are made of high-hardness, anti-rust brass to prevent rusting during daily use, rendering the manhole cover inoperable.

3. Fall Protection

High load-bearing capacity. During testing, a ductile iron manhole cover withstanding 500KN of pressure remained undamaged, far exceeding the capacity of (360KN). It can bear various heavy-duty trucks, effectively preventing accidents caused by the manhole cover falling.

4. Anti-slip

Exquisite casting techniques ensure a clear product line. The manhole covers feature common anti-slip patterns, enhancing friction to prevent pedestrians from slipping on rain, snow, or ice.

5. Materials

Increase the density of the products to enhance their compression, bending, impact, heat, cold, wear, acid and alkali resistance, aging resistance, and deformation resistance.
