Press-Locked Bar Grating is a steel grating product that tightly locks the cross bars (typically shorter than the bearing bars) and bearing bars together using high-pressure mechanical equipment. Compared to traditional welded steel gratings, press-locked grating offers higher strength, durability, and better aesthetics and stability. The unique manufacturing process ensures uniform hole spacing and a smooth surface, making it widely used in commercial buildings, landscape designs, industrial platforms, and municipal facilities.
