Q235 Metal Building Materials Rain Water Drainage Trench Driveway Galvanized Grating
The press-lock steel grid is constructed with two close-tolerance slotted bars bonded together by tremendous hydraulic pressure. This production method creates a permanent locking mechanism. With high strength and firm structure, it's widely used in industrial factories or parks, commercial buildings, and municipal engineering as stair treads, platforms, walkways, security screens, tree covers, trench covers, and drainage covers.
Only the bearing bars are notched, while the cross bars are common plain steel. They have different heights to accommodate various applications.
