Press lock grating is also called pressed grating or pressure lock grating, which is made of low carbon steel, stainless steel or aluminum. The press-locked grating is constructed with two close-tolerance slotted bars bonded together by tremendous hydraulic pressure. And this production can let press-locked grating be a permanent locking. With high strength and firm structure, it's widely used in industrial factories or parks, commercial buildings, municipal engineering as stair treads, platforms, walkways, security screens, tree covers, trench covers, drainage covers and so on. Serrated surface is also available for anti-slide effect.
