Xian Ke Hua Steel Co., Ltd. is a professional angle, channel retail galvanized square tubes, galvanized angle steel, galvanized channel steel, square tubes, rectangular tubes, galvanized pipe, galvanized rectangular tubes, welded pipe, galvanized pipe galvanized round steel, galvanized square tube beam cutting, steel production and sales. Cold drawn rectangular tube, used as a starting material is a hot-rolled coil, in use, the first with an acid, said oxidation transdermal absorption, followed by cold rolling, so that the products of the cold-rolled, steel pipe, hardness and strength, are improved, but the toughness drops slightly. Therefore galvanized square tube cutting, which will result in a stamping when performance is reduced, cold-rolled production can only be a simple rectangular tube deformation parts manufacturer. Xian Ke Hua Steel Co., Ltd. is a professional angle, channel, galvanized angle steel, galvanized channel steel, square tubes, rectangular tubes, galvanized pipe, galvanized rectangular tubes, welded pipe, galvanized pipe, galvanized steel bar , I-beam, steel production and sales. Hot-rolled square and rectangular tube galvanized pipe, billet, plate rolling early as the raw material, and then through the furnace, even when using high-pressure water, surface phosphorus removal work, then use the roughing mill, the roughing mill is to cut off the head of the main and the tail tube moments, and then in the pipeline, and then fed to the precision finishing rolling mill, a computer-controlled. Square tube layer after cooling, after rolling winder, then curl. However, when re-curl, thickness often, and as some kind of error accuracy. Xian Ke Hua Steel Co., Ltd. is a professional angle, channel, galvanized angle steel, galvanized channel steel, square tubes, rectangular tubes, galvanized pipe, galvanized rectangular tubes, welded pipe, galvanized pipe, galvanized steel bar , I-beam, steel production and sales. Torque tube is a hollow rectangular strip steel, also known as flat tubes, flat square tube or pipe name implies flat square and rectangular tube, pipe storage site or warehouse, should be selected in the clean, smooth drainage area, away from harmful gases or dust factories and mines.
