Used banding steel grating to design and manufacture. Widely used in urban road, square, garden, docks and airports, parking lot, highway, railway, industrial engineering and other kinds of industrial and civil architecture.
Line forthright, silver appearance, modern trend.
Leakage area is 83.3%, which is more twice than cast iron.
Rustproof force is powerful, free maintenance and replacement.
Cover and frame connecting with hinge, guard against theft, safety, and easy to open.
When big span, and heavy load, the price is lower than cast iron, economizing the expenses of stolen or replacement.
The strength and toughness are far higher than cast iron, and can be used in docks, airports, and other large span and heavy load places.
Meets different environmental conditions, loads, spans, sizes, and shapes.
Our company thanks every customer for their trust in us, and is very happy to be able to provide customers with a full range of engineering solutions through Alibaba. The customer's previous supplier had problems, so he looked for suppliers again in Alibaba. After seeing our factory certification and technical design scheme, the customer decided to place an sample order. After receiving the goods, he was very satisfied. Now he has become our long-term partner. We are committed to serving customers and creating greater value for customers.

Steel drain grating offers a much higher drainage leakage area (83.3%, more than twice that of cast iron), significantly higher load-bearing strength and impact toughness, better anti-theft design with hinged frames, and lower comprehensive cost for large span installations.
We manufacture using Mild Steel (ASTM A36, Q235, S275JR), Stainless Steel (304/316), and 6063 Aluminum Alloy. For steel products, hot-dip galvanizing is standard to ensure long-term rust protection and zero maintenance.
Yes, full customization is supported. We can adjust bearing bar thickness, pitch spacing (metric and US standards), frame configuration, and overall geometry to match your project load requirements.
Our MOQ is 1 piece, allowing customers to evaluate quality with a sample order. We provide a 2-year quality warranty on our steel drain grating products.
They are widely used in urban roads, municipal squares, gardens, dock facilities, airports, parking lots, railways, expressways, and diverse heavy-duty industrial and civil construction projects.
The steel grate cover and the embedded outer frame are connected securely with structural hinges, ensuring anti-theft security while maintaining ease of opening for regular municipal and industrial cleaning.
