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.

1. What is press locked steel grating?
Press locked steel grating is a type of steel grating where the cross bars are tightly locked to the bearing bars using high-pressure mechanical equipment. This process enhances strength, stability, and aesthetics compared to traditional welded gratings, making it ideal for commercial, industrial, and municipal applications.
2. How does press lock grating differ from press welded gratings?
Unlike press welded gratings, which join bars using heat and welding, press lock grating relies on mechanical pressure to lock the bars together. This method results in a more uniform surface, better load-bearing capacity, and longer-lasting durability.
3. What are the advantages of using press locked steel grating?
Press locked steel grating provides higher strength, improved durability, and a smooth, aesthetically pleasing surface. Its precise hole spacing and stability make it suitable for industrial platforms, walkways, landscape designs, and municipal projects.
4. Where is pressure locked grating typically used?
Pressure locked grating is widely applied in commercial buildings, industrial platforms, pedestrian walkways, drainage covers, and urban infrastructure. Its strong load-bearing ability and reliable structure make it a preferred choice over traditional gratings.
5. Can press lock gratings handle heavy loads?
Yes, press lock gratings are designed to withstand heavy loads due to their tightly locked cross bars and bearing bars. This makes them suitable for industrial, commercial, and municipal environments where strength and safety are critical.
