Standard Steel Gratings

Steel grating is a durable, load-bearing open grid assembly, typically made of carbon or stainless steel, designed for platforms, walkways, drainage covers, and stair treads. It is widely used in industrial and commercial settings for high strength-to-weight ratios, allowing light, air, and liquid passage. Common types include welded, press-locked, and heavy-duty, with galvanized coatings for corrosion protection.

Product Introduction

Stainless Steel Bar Grating provides a long-term durable grating solution for caustic atmospheres where corrosion resistance and minimum carbide precipitation are important considerations. Typical applications include stairs and platforms within chemical production and storage, food processing plants, and water and wastewater treatment facilities. It is also used in many other commercial and architectural applications. Your choice of 304, 304L, 316, or 316L Stainless Steel grades are available.

Serrated：Another method for improving slip resistance is the use of serrated grating. The serrations are made up of small notches cut into the load bar during the slitting of the material as one process, providing a low cost solution for improving slip resistance.

Advanced manufacturing technology ensures the flatness and precision of the steel grating surface. Strict quality control during the production process of steel grating ensures its uniformity and stability. The successful development of 5800×1000mm steel grating reflects a leap in industry technology and demonstrates the excellent innovation ability of the R&D team.

The widespread application of such large steel grating will significantly enhance the performance and efficiency of related equipment, driving technological advancements in more fields.

Welded Steel Grating: The most popular type, manufactured by electro-forging, where bearing bars and cross rods are welded to create a robust, permanent grid.

Press-Locked Grating: Features interlocking bars pressed together, ideal for architectural applications where a clean, smooth appearance is needed.

Heavy-Duty Grating: Utilizes deeper, thicker bearing bars to handle higher loads, suitable for high-traffic areas, vehicle loading, and large spans.
