The press-locked aluminium grating is a special groove punched out in advance on the bearing bars, inserting the aluminium bars into the bearing bars groove, and pressing the inserting bars into the bearing bars by hydraulic press, thus forming a solid network structure by bearing and inserting bars.

Aluminum grating is a new type of platform material. It uses aluminium alloy material to form a net-like integral structure through rod piercing and extrusion. It has the advantages of light weight, beautiful appearance, corrosion resistance and high strength. It is widely used in marine engineering, architectural decoration and other industries. Aluminum gratings are generally made of 6063 Aluminium alloy, or 6061 or 6082.
