Description

According to different flat bar specifications, press-locked steel grating can be made into lightweight ceiling panels or heavy-duty load-bearing gratings.

Press-locked Steel Grating is manufactured through a press-locking process, where flat bars are mechanically locked with cross bars under high pressure without welding. According to different flat bar specifications, it can be produced as both lightweight ceiling panels and heavy-duty load-bearing grating systems.

It offers a clean appearance, high precision structure, and excellent versatility for industrial and architectural applications.
