GNEE STEEL supplied a batch of hot-dip galvanized steel grating covers for the construction of a road drainage system. The high rainfall in the area demanded high load-bearing capacity, excellent anti-slip properties, and long-term corrosion resistance. We carefully considered drainage efficiency and safety during the design phase, utilizing a staggered welded structure of standard flat steel and twisted square steel to ensure high strength and drainage efficiency. Since its implementation, the product has effectively improved the drainage capacity of urban roads, reduced water accumulation and slip accidents, and has received widespread praise from municipal authorities.

What is Steel Grating​？

Steel grating, also known as bar grating or metal grating, is an open grid assembly of metal bars. The bearing bars run in one direction and are spaced by rigid attachment to perpendicular cross bars or by bent connecting bars extending between them. This design is intended to hold heavy loads with minimal weight. Steel grating is widely used for floors, mezzanines, stair treads, fencing, trench covers, and maintenance platforms in factories, workshops, motor rooms, trolley channels, heavy loading areas, boiler equipment, and heavy equipment areas.

Raw Material：

1.Galvanized steel grating:A36 is the common grade. After welding is completed, surface treatment will be carried out: mild steel grating will be hot-dip galvanized or painted to make it look beautiful or corrosion-resistant.

2.Stainless steel grating:Common grade is SS201, 304, 316, 316L. Stainless steel grating itself has a strong corrosion resistance, suitable for food processing and chemical fields.

3.I Bar Steel Grating:With its unique I-section design, it exhibits excellent bearing capacity and stability, and is suitable for heavy-loaded industrial platforms, bridges and other places, and has both ventilation and light transmission properties.
