Durable material: load-bearing steel mesh for the trench cover, galvanized and rust-proof, durable, versatile and versatile, the overall grid is evenly distributed and the load capacity is high, beautiful appearance, accurate diameter Strong Load Capacity The welding and bending process has a high load capacity and uses a mechanical welding method to improve quality and efficiency. Twisted square steel, increases the tensile force of the structure Wide application: stainless steel sieve grid drain cover, suitable for kitchens, patios, to use around swimming pools, paths, gardens, paths and landscape areas, etc., quick and easy to install Craft: professional welding process, metal grilles for drainage have strong welded joints, so it is difficult to break at the weld, the drain cover for rolling driveways will not be deformed or dented, you can use it without hesitation Rectangular structure: the holes of the grate are dense and well sized to stop leaves and dirt, drain quickly without clogging, and at the same time no snow and dust accumulate
