Cast Iron Grating Product Features:
Noise Reduction
No noise, meets environmental protection requirements. This is a new requirement for the design of new-style manhole covers. The new five-protection manhole cover design incorporates a design philosophy that ensures vehicles 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.
Anti-theft
Equipped with anti-theft design, featuring high-hardness, rust-resistant brass locks and keys to prevent rusting during daily use, making it impossible to open the manhole cover.
3. Fall Protection
High load-bearing capacity. During testing, a ductile iron manhole cover withstanding 500KN of pressure was not damaged, far exceeding the capacity of (360KN). It can bear heavy-duty trucks, effectively preventing accidents caused by manhole cover falls.
4. Anti-slip
Exquisite casting techniques ensure the product line is clear. The manhole covers feature common anti-slip patterns, increasing friction to prevent pedestrians from slipping on rain, snow, or ice.
5. Materials
Increase the density of the products, enhancing their ability to withstand compression, bending, impact, heat, cold, abrasion, acidity and alkalinity, aging, and deformation resistance.
