Dense steel grating refers to a pressed welded steel grating with a spacing of less than 25mm between flat steel plates. In addition to fully possessing the advantages of standard pressed welded steel grating in terms of aesthetics and easy installation, it also meets the strict requirements for the size of objects passing through or leaking in some special occasions. For example, in civil occasions with large pedestrian flow, dense steel grating can meet the requirements of women's high heels walking; For example, in industrial and mining enterprises with large pedestrian flow, it is required that no larger objects (such as steel balls with a diameter less than 20mm) are allowed to fall to meet safety needs, and so on.

Specification of dense steel grating: The spacing between flat steel bars is 12 or 20mm, and the horizontal bars are difficult, with a spacing of 30 or 50mm.

The application of dense steel grating is mostly used in places with high requirements for grid lattice, such as ships, drilling platforms, offshore work platforms, sidewalks, etc., to prevent objects from falling. Dense steel grating is also commonly used in places such as high-altitude work platforms in factories and high-rise work platforms in workshops to prevent injuries caused by high-altitude objects.
