Stainless Steel Grating
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.
What Is Stainless Steel Grating?
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 costeffective, 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.
Construction Types
Welded Stainless Steel Bar Grating (WS type): Durable and cost-effective
PressLocked SS Grating: Smooth top, higher lateral stiffness
SwageLocked SS Grating: ADA-compliant low-profile design
Dovetail Style (DTS): Architectural-grade finish for visible installations

Application Fields
Stainless steel grating is widely used in power plants, chemical plants, refineries, steel mills, machinery manufacturing plants, shipyards, paper mills, cement plants, pharmaceuticals, food processing plants, as well as bridge projects, municipal engineering projects, sewage treatment and other environments with high anti-corrosion requirements. The selection of stainless steel grating is the same as that of carbon steel grating.
Product Advantages
Durability
Stainless steel grating has inherent corrosion and oxidation resistance, which greatly reduces maintenance costs. Its service life far exceeds that of ordinary steel grating, making it an ideal choice for long-term investment.
Safety
The stable structure and scientifically designed grid and crossbar spacing effectively prevent slipping and falling accidents, providing comprehensive protection for personnel and equipment.From pedestrian load (300–500 kg/m²) to heavy-duty vehicular load (>5000 kg/m²), our load-span charts comply with ASTM/ISO standards for safe design.
Aesthetics
Smooth lines and modern texture, easily integrated into various architectural and environmental styles, from industrial style to simple modern style, perfectly adapted. Optional serrated bearing bars reduce slip risk in industrial floors and wet environments such as industrial walkways, stair treads, and trench covers.
Environmental protection and energy saving
Good ventilation and drainage performance, conducive to air circulation, reduce water accumulation, in line with the concept of environmental protection, help create a green space.
