Time:

2025-01-20

Steel gratings are versatile materials widely used in industrial, commercial, and municipal sectors. These products are designed with parallel or elongated regular spacing and offer exceptional strength-to-weight ratios. The gratings are easy to fabricate into nearly any configuration, making them ideal for flooring, walkways, stair treads, ventilation, and more.

Categories of Steel Gratings

1. Bar Grating

Bar grating is composed of parallel bearing bars and cross bars that are connected by various methods, including welding, press-locking, or swage-locking. This grating type is used for heavy-duty applications due to its strength.

Types of Bar Grating:

Type	Description	Common Applications
Welded Steel Grating	Bars are welded together for a strong, rigid structure. Available with plain or serrated surfaces.	Walkways, platforms, drainage covers, stair treads.
Press-Locked Steel Grating	Crossbars are pressed into slotted bearing bars for locking, offering a smooth surface.	Ceilings, platforms, floors, fences.
Swage-Locked Grating	Crossbars are inserted and swaged into pre-punched holes in bearing bars.	Platform ceilings, outdoor curtain walls.

2. Safety Grating

Safety gratings are designed to improve traction and reduce the risk of slipping. Made from perforated metal sheets, these gratings are ideal for walking surfaces in high-traffic areas.

Types of Safety Grating:

Type	Description	Common Applications
Diamond-Strut Safety Grating	Features a unique strut design that provides superior slip resistance.	Walkways, stairs, ramps.
O-Grip Safety Grating	Perforated with debossed holes to prevent slips, available in various materials like steel and aluminum.	Floors, walkways, platforms, working platforms.
Traction-Grip Safety Grating	Equipped with perforated buttons to maximize traction in all directions.	Stair treads, walkways, working platforms.
