Cast Iron Grating Product Features:
Noise Reduction
Noise-free and meets environmental protection standards. This is a new requirement for the design of the new type of manhole cover. The innovative five-protection design of the manhole cover incorporates a design concept that ensures vehicles collide with the edge of the ring rather than the cover itself upon passing, preventing the entire cover from sinking. Effectively addresses the "worn edge" issue around urban manhole covers.
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, a 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 manhole cover falls.
4. Anti-slip
Exquisite casting techniques ensure a clear product line. 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 compressive, bending, impact resistance, heat and cold resistance, wear resistance, acid and alkali resistance, aging resistance, and deformation resistance.
