Stainless steel grating for sale from China

We are selling stainless steel grating from China.

Stainless steel grating is a kind of steel grating product which is made of stainless steel flat steel and cross bars arranged at a certain interval, and welded by high-voltage resistance welding machine automation equipment or manual welding. Its surface is polished to remove welding slag or scars left in the welding process , and the surface can be spray-painted, which has the characteristics of beautiful and durable, non-slip, and strong load-bearing capacity.

Stainless steel grating, also known as stainless steel bar grating or SS grating, is a load-bearing metallic grid manufactured via electrical resistance welding, press-locking, or swage-locking of stainless steel bearing bars and cross bars. It provides excellent airflow, light transmission, and drainage, while offering durable strength and clean aesthetics.

1.Grades & Surface Treatments

304 Stainless Steel Grating: Most cost?effective, suitable for indoor/mild outdoor use

316 / 316L Stainless Steel Grating: High-performance for coastal, corrosive, and chemical environments

Finishes Available:

Mill/As-pickled

Brushed (Satin)

Mirror-polished

Serrated (anti-slip)

Powder-coated or painted

2. Load-bearing capacity: Depending on the model and specifications, the stainless steel grating can withstand different loads from light pedestrian traffic to heavy vehicles. The load-bearing range is wide, ranging from tens of kilograms to several tons per square meter. The specific parameters are customized according to your choice.

3. Surface treatment: The stainless steel grating becomes matte grayish white after pickling and passivation treatment, while electrolytic polishing makes the surface bright and smooth . The surface can be painted or sprayed with plastic to make the color richer.

4. Crossbar spacing: Reasonable crossbar spacing design, such as 50mm and 100mm, can not only ensure the stability of the structure, but also effectively prevent objects from falling.

5. Flat Iron Type: The Bearing Bar types of stainless steel grating can be divided into flat type, toothed type and I type. The serrated surface can enhance the anti-slip ability of the stainless steel grating.
