Galvanized steel grating are required to be machined to any size and shape

Galvanized steel grating external quality has uneven color, exposed white, impurities, bubbles (surface, middle, bottom), stratification, thickness deviation, insufficient curing degree, rich resin layer, cracking (curing, rich resin, mold), thimble defects, warping, repair defects and other defects, must establish a set of strict quality inspection standard system and specifications. Insert and pull type steel mesh frame, also known as reverse insert and pull type steel mesh frame, is made of ordinary low-carbon flat steel, stainless steel, brass plate and a certain size of aluminum plate by grooving (hole), insert and pull, welding, finishing and other processes. Product solder joint firm, hole spacing uniform, beautiful design, convenient and practical. The insert type steel mesh frame has the characteristics of high strength, corrosion resistance and maintenance free, uniform and precise combination, light and delicate structure, natural harmony and elegant style. It is both a usable product and a work of art. It is widely used. The material of steel grid plate can be made of flat steel with a width of 20-70 mm and a thickness of 2-10 mm and twisted square steel (cross bar) made of 6-8 mm by drawing and twisting. The flat steel is placed side by side and parallel, and the twisted square steel is placed vertically and horizontally on top of the flat steel, which is pressed together by a high-power welding Transformer model and a high-pressure piezoresist welder. Flat steel mainly plays the role of load-bearing, twisted square steel mainly plays the role of fixing flat steel and anti-skid. Products mainly implement the requirements, the material is ordinary carbon steel. Products generally have two types (i.e. horizontal bar spacing of 50mm and l00mm), there are three main series (i.e. vertical bar spacing of 30, 40, 50mm) and more than 159 varieties. Can also be processed into any size and shape according to user requirements.
