Square Ductile Iron Rainwater Grate

Urban infrastructure relies heavily on unobstructed drainage-and KSHD's ductile iron square rainwater grate is the indispensable core component for reliable system performance.

Crafted primarily from ductile iron (matching cast steel in strength), our grates withstand heavy pressure, impacts, and frequent vehicle traffic while retaining structural integrity-boosting safety and dependability. Superior to cast steel in corrosion and oxidation resistance, they're ideal for coastal or rainy regions. Enhanced by spheroidization treatment and surface finishes (hot-dip galvanizing or asphalt coating), our grates resist chemical erosion, extending service life and slashing maintenance costs-your cost-effective, long-lasting procurement solution.

Ⅰ. Widely applicable to various scenarios

Urban road drainage: The rainwater grate on the road is an important entrance to the urban drainage system. The square ductile iron rainwater grate can quickly guide the rainwater on the road into the drainage pipe, prevent water accumulation on the road, and ensure the safe passage of pedestrians and vehicles.

2. Community drainage: In residential communities, underground garage drainage ditch covers and rainwater grates bear the heavy responsibility of collecting and discharging rainwater and sewage. And our rainwater grates can withstand the frequent rolling of vehicles in the community to ensure the safety of vehicles and personnel. Ensure the long-term stable operation of the drainage system and create a safe and comfortable living environment for residents.

3. Garden landscape facilities: The square ductile iron grate is not only practical, but its simple appearance can be integrated with the garden landscape, and it does not affect the overall landscape effect while draining water. Whether it is a park, green space or scenic spot, different products can be used to meet drainage needs.

Ⅱ. Product Features

High load-bearing capacity: The product has undergone strict quality inspection, and its load-bearing capacity far exceeds similar products. In the test, some ductile iron grates can even bear 500KN pressure without damage, which far exceeds the national standard and EU EN124 standard, and can effectively prevent safety accidents such as grate rupture and vehicle falling caused by insufficient load.

2. Anti-theft design: To prevent the product from being stolen, we have adopted a variety of anti-theft measures. The ordinary anti-theft design connects the grate and the well ring with high-strength bolts to form an integrated structure; the new anti-theft design uses a special lock and key. The lock is made of high-strength, rust-proof copper, which not only ensures the durability of the lock, but also prevents the grate from being unable to open due to rust.

3. Anti-slip design: Considering the safety of pedestrians walking in rainy days, the surface of the grate is designed with different anti-slip patterns or textures, which greatly increases the friction, effectively prevents pedestrians from slipping due to rain, snow, and ice, and ensures the safety of pedestrians.

Ⅲ. Quality Assurance

We have advanced production equipment and a professional technical team. From raw material procurement to product production and testing, every link strictly follows national standards and industry specifications. The raw materials are made of high-quality ductile iron to ensure the stability and reliability of product quality.

In the production process, advanced casting technology and processing technology are used to ensure the dimensional accuracy and appearance quality of the products. Before leaving the factory, the products undergo strict quality inspections, including load-bearing capacity tests, corrosion resistance tests, appearance inspections, etc., to provide customers with reliable products.
