Steel bar grating made of 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.
Welded Grating
Dovetail Pressure Locked
The most commonly used and economical design suitable for most industrial applications.Manufactured by welding the bearing bar and cross bar intersection, typically with automated forge welding equipment or professional manual welding. Available in carbon steel or stainless steel.
Insert the cross bar into the pre-punched bearing bar and hydraulically deform it to lock it in place.The cross bar here is usually a straight plate shaped like a bearing bar.
Swaged Pressure Locked
Welded Swaged Pressure Locked
Assembled by inserting pre-punched bearing and cross bars into an "egg-crate" configuration and deforming the cross bars under intense hydraulic pressure. Available in all materials and ideal for architectural and ornamental applications.
It is an upgraded version of the swaged pressure locked,Each intersection is manually welded once to make it stronger and can withstand more loads.
