Cast Iron Grating

Cast Iron Grating Product Features:

Soundproofing

No noise, meets environmental protection requirements. This is a new requirement for the design of new manhole covers. The new five-protection manhole cover design adopts a design concept that allows vehicles to hit the edge of the manhole ring instead of the cover itself upon passing, preventing the overall sinking of the manhole cover. Effectively addresses the "deteriorated edge" issue around urban manhole covers.

2. Anti-theft

Features anti-theft design; locks and keys are made of high-hardness, corrosion-resistant brass to prevent rusting during daily use; manhole cover cannot be opened.

3. Fall Protection

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

4. Anti-slip

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

5. Materials

Increase the density of the products, enhancing their resistance to compression, bending, impact, heat, cold, wear, acidity and alkalinity, aging, and deformation.
