The 30mm pitch series plug-in steel grating is a more commonly used type, and its applications are products in various industrial fields. The center distance of the loaded flat steel of this series of steel grating is 30mm, which meets the requirements of American standards. It has strong resistance to surface impact. It is widely used in refineries, power plants, sewage treatment plants, granaries, chemical plants, highways, airports and docks and other platforms, walkways and drain covers, stair steps, etc. Among them, toothed steel The grid can be used in wet and slippery places, especially for offshore oil production platforms.


The 40mm-pitch series plug-in steel grating is more economical and lighter. It meets the specifications of fixed platforms, walkways and stairs specified by the British Standards. It is an ideal product for small spans, even in the aisles of transportation equipment. The load is no exception, and it can also be used to make warehouse shelves, pavilion panels, trestle bridges, protective fences, sun curtains, etc.


The 60mm-pitch series plug-in steel gratings are specially developed for the application of the mining industry. It solves the problem of mineral splashing on the board. This series of steel gratings has a nominal size of 50*60mm through the air, allowing Most of the splashing material falls through, thus ensuring the cleanness and safety of the board surface.This product is often designated for the board surface in the crushing system, the aisle on the conveyor line, the ball mill, the processing plant and the operation station.
