Inserted steel grating, also known as interlocking steel grating or compression steel grating, is a steel grating product made from materials such as carbon steel, stainless steel, brass, and aluminum through processes such as grooving, insertion, and welding. According to the insertion method, interlocking steel gratings can be divided into four categories: pressed type, heavy-duty type, integral type, and sunshade type. The pressed type uses crossbar flat steel for press-locking, with a maximum processing height of 100mm; the heavy-duty type is pressed under 1200 tons of pressure and is suitable for high-load-bearing locations; the integral type has a flat steel groove depth of 1/2 height; the sunshade type is formed by press-locking with 30° or 45° inclined grooves.
Interlocking steel gratings have many advantages, including strong welds, uniform hole spacing, flat mesh surface, beautiful design, practicality, lightweight, high strength, corrosion resistance, and maintenance-free operation. They are widely used in civil and commercial buildings, theaters, subways, urban rail transit, and other municipal engineering fields. They can be used for ceilings, interior and exterior decoration, platform walkways, ventilation windows (wells), billboards, and various covers. Interlocking gratings feature strong welds, uniform hole spacing, flat mesh surface, and beautiful and practical design, making them both functional and artistic products.
Over the years, hundreds of varieties have been developed, with sixteen exported products that are highly favored by customers. Interlocking steel grating is widely used in factory lobbies, theaters, shopping mall ceilings or interior decoration, and can also be used for platform walkways.
