Prevent noise: Manhole cover and frame seal perfectly, preventing vehicle noise.

Security: No recycling value for the products and hence doesn’t encourage thievery.

Fall prevention: Bearing capacity is strong, carrying capacity is highly superior to double covers as per standards.

Antiskid: Covering non-slip texture increases the friction force and hence prevents the skid because of rain, snow, and ice.

Material: High quality fiber glass material which improves the density of the product. The product has strong compressive length, impact resistance, cold resistance, wear resistance, acid and alkali resistance, ageing resistance and is not easy to deform.
