Steel Bar Grating

Steel bar grating is a rigid, open-grid flooring product made from bearing bars and cross rods, welded or forged at each intersection. It is widely used for industrial walkways, platforms, stair treads, trench covers, and drainage grates where high load capacity and open drainage are required.

Product Structure

Steel bar grating consists of load-bearing bars spaced at regular intervals, welded to transverse cross rods at right angles. The open grid allows light, air, water, and debris to pass through while providing a strong walking surface. Bearing bars may be plain, serrated, or I-bar shaped depending on the application and slip resistance required.

Key Features

• High load capacity: supports pedestrian, forklift, and vehicular loads depending on bar size and spacing.

• Open design: 70% to 85% open area for drainage, light, and air flow.

• Non-slip options: serrated bearing bars for wet or oily environments.

• Durable finishes: hot-dip galvanized, painted, stainless steel, or aluminium.

• Low maintenance: galvanized grating requires no painting for decades.

• Lightweight yet strong: weighs less than solid plate while supporting heavy loads.

Types and Materials

Carbon steel grating (hot-dip galvanized) is the most common and economical choice for industrial platforms and walkways. Stainless steel grating is used in corrosive environments such as food processing, chemical plants, and coastal areas. Aluminium grating is selected for lightweight, non-sparking applications.

Applications

Steel bar grating is used in refineries, chemical plants, wastewater treatment works, power substations, ship decks, offshore platforms, parking garages, stadiums, and commercial building floors. It is the standard choice for industrial flooring where drainage and ventilation are required.

Custom Sizes

Grating panels are custom-manufactured to project requirements: bearing bar heights from 20 mm to 100 mm, bar spacings from 20 mm to 60 mm, and panel lengths up to 6 m. Special shapes, cutouts, and stair treads are available on request.

Conclusion

Steel bar grating is a versatile, high-strength flooring solution for industrial and commercial applications. Its open design, load capacity, and low-maintenance galvanized finish make it the preferred choice for walkways and platforms worldwide.
