Metal grating is collectively referred to a wide range of fabricated metal products that have essentially identical, parallel or elongated regular spacing. It is strong and durable with an exceptional strength-to-weight ratio and can be easily fabricated to nearly any configuration. It is widely used in various industrial and commercial applications and serves as platforms, walkways, ceilings, floors, stair treads, trench covers and sun shades in factories, building decorations and municipal works.
According to its manufacturing process, metal gratings are divided into two main categories: bar gratings and safety gratings.
Bar grating
Safety grating
Bar grating, also known as steel grating, is generally made up of parallel cross bars that are connected together with perpendicular bearing bars. As these bars are commonly connected through welding, press-locking or swage-locking, therefore, our bar gratings are divided into welded steel grating, press-locked steel grating and swage-locked grating.
Welded steel grating is the most popular and versatile of all the industrial grating types. It consists of bearing bars that are automatically resistance-welded with the cross bars via precise use of intense heat and pressure. This produces a rugged, one-piece panel with cross bars that are extremely rigid, yet smooth enough for easy, safe walking. Both plain and serrated surfaces are available. It is widely used as walkways, safety barriers, drainage covers, platforms, ventilation grates and stair treads.
Specification
19-W-2, 19-W-4, 15-W-2, 15-W-4, 11-W-2 and 11-W-4 are commonly used industrial grating sizes. Of which, for example, 19-W-4, W stands for welded steel gratings. 19 represents the spacing between bearing bars is 1-3/16 "on center while 4 means the spacing between cross bars is 4" on center. Other sizes are much similar to 19-W-4.
Instead of welding the joints together, press-locked steel grating relies on employing enormous hydraulic pressure that fuses the two close-tolerance slotted bars together. Permanent locking is achieved by forcing the deep cross bar into the notched bearing bar. Both plain and serrated surfaces are available. It is widely used for ceilings, platforms, floors, fences and all kinds of covers in the factories, civil and commercial buildings.

19-P-2, 19-P-4, 15-P-2, 15-P-4, 11-P-2 and 11-P-4 are commonly used industrial grating sizes. Of which, for example, 19-P-4, P stands for press-locked steel gratings. 19 represents the spacing between bearing bars is 1-3/16 "on center while 4 means the spacing between cross bars is 4" on center. Other sizes are much similar to 19-P-4.
Swage-locked grating, also known as aluminum grating, is mainly made of aluminum bars and manufactured by inserting cross bars into pre-punched holes in the bearing bars. The cross bars are then swaged forming a positive mechanical connection. The cross bars are recessed below the top surface of the bearing bars providing a uniform and attractive architectural appearance. It is mainly used for platform ceilings and outdoor curtain walls.
Specification
19-SG-2, 19-SG-4, 15-SG-2, 15-SG-4, 11-SG-2 and 11-SG-4 are commonly used industrial grating sizes. Of which, for example, 19-SG-4, S stands for swage-locked steel gratings. 19 represents the spacing between bearing bars is 1-3/16 "on center while 4 means the spacing between cross bars is 4" on center. Other sizes are much similar to 19-SG-4.
Safety grating is a type of metal grating that is widely used as walking surfaces to improve traction and reduce the risk of slips and falls. It is generally made from metal sheet that is perforated or cold stamped in a variety of patterns. According to its patterns, our safety gratings are divided into diamond-strut safety grating, O-grip safety grating and traction-grip safety grating.
Swage-locked grating, also known as aluminum grating, is mainly made of aluminum bars and manufactured by inserting cross bars into pre-punched holes in the bearing bars. The cross bars are then swaged forming a positive mechanical connection. The cross bars are recessed below the top surface of the bearing bars providing a uniform and attractive architectural appearance. It is mainly used for platform ceilings and outdoor curtain walls.
Specification
O-grip safety grating is made of carbon steel, aluminum and stainless steel and produced by cold processing. Its large debossed holes and perforated buttons help provide maximum slip protection and performance under practically all conditions and in every direction. It prevents rain, snow and dust from accumulating and is widely used as walkways, floors, slopes, stair treads, fashion shows and working platforms in commercial and industrial applications.
Specification
Traction-grip safety grating is generally made of is made of carbon steel, aluminum and stainless steel and produced by cold-shaped. It features a surface with hundreds of perforated buttons that provide slip-resistance in all directions making it a practical choice for industrial applications. It is widely used as walkways, floors, stair treads, and working platforms in commercial and industrial applications.
