Steel grating is made by welding bearing bars and cross bars at set intervals to form a strong, square-mesh structure. It is typically divided into stainless steel grating and carbon steel grating based on material. Most carbon steel grating is hot-dip galvanised to improve corrosion resistance.
Common sizes:
– Bar spacing: 25–60mm (custom)
– Cross bar spacing: 50mm or 100mm (standard)
Key features: high strength, corrosion resistance, low maintenance.
Typical uses: drain covers, platform flooring, stair treads, driveway, walkway and heavy duty grating. Industrial applications: petrochemical plants, power facilities, municipal engineering.

Product Overview
Steel grating (often called bar grating) is a steel structure made of load-bearing bars and cross bars arranged at right angles, joined by welding or press locking. The open-grid design gives it excellent strength, ventilation, light transmission, heat dissipation, slip resistance, and explosion-proof performance – making it the go-to choice for modern industrial platforms and building facilities.
To meet different working conditions, steel grating can be divided into several types by welding method, bearing bar shape, application, and material.

Core Structure & Benefits
– Strong and stable – uses high-quality flat bars and tough twisted square bars as cross bars.
– Great performance – open grids let light and air through, while the grid surface provides natural slip resistance, improving safety.
– Long service life – high load capacity, corrosion resistant, and easy to maintain. Low total lifecycle cost.
Thanks to these features, steel grating offers a unique combination of strength, safety, and economy.

Material Options – Choose what fits your site conditions
Carbon steel grating
Cost-effective. Usually hot-dip galvanised for good rust and corrosion protection. Suitable for most industrial environments.
Stainless steel grating
Made of stainless steel – excellent corrosion resistance. Ideal for food processing, chemical plants, coastal areas, or anywhere hygiene and high corrosion resistance matter.
After choosing the material, the next step is to decide the surface finishing – which directly affects product life in different environments.
