Steel bar grating with high strength and firm structure is made up of carbon steel, aluminum steel, or stainless steel. According to the manufacturing methods, it can be divided into four types: welded, press-locked, swage-locked, and riveted gratings. According to the surface shapes, it can be divided into smooth and serrated gratings. With various styles and sizes for choice, steel gratings are widely used in everyday life, such as stair treads, walkways, platforms, floors, various covers, wheeled equipment, security screens, heavy-duty constructions, and so on.
Welded bar grating
Welded bar grating is also called metal open ba!grating. Welded bar grating, also known as metaopen bar grating, comes in two types: smoothand serrated. Smooth, or plain steel bar grating, ismore popular, but serrated grating offers betterskid resistance.
Press Lock Grating
Made from low carbon steel, stainless steel. 0aluminum, is created by bonding slotted barsunder hydraulic pressure. lt's strong, durable, andwidely used in industrial and commercialapplications like stair treads, platforms,walkways, and covers.Serrated surfacesenhance anti-slip properties.
Swage Locked Grating
Swage locked grating, mainly made of aluminumor stainless steel bars, is formed by insertingcross bars into pre-punched bearing bars andlocking them under hydraulic pressure.lt comesin three bearing bar types: rectangular, T and lbars, with l bars being lighter and moreaffordable.
