Steel hooks. There are three forms were semicircle hook, hook and straight oblique hook. After the steel bending, bend endothelial contraction, skin extending the length of the same axis, forming a circular bend, bent after a size larger than the sizes of materials should be considered bending adjustment value. Reinforced apex diameter 2.5d, the flat part of 3d. Steel hooks to increase the length of the theoretical value: to turn semicircle hook for 6.25d 10.5mm rod rebar manufacturing plant, to hook straight to 3.5d, for oblique hook for 4.9d. Welded into bonding and welding two forms. Including flash butt welding pressure, and pressure resistance spot welding; welding, including arc welding and electroslag welding. In addition, steel and embedded parts welded T-joints should be used submerged arc welding pressure 10.5mm rod rebar suppliers, but also electric arc or perforated plug welding, welding current but not large, reinforced to prevent burns. Flash butt welding is widely used in reinforced and prestressed steel connecting rods and screw terminal welding. Hot-rolled steel by flash butt welding should be a priority. 10.5mm rod rebar manufacturers, steel wire rod, cold rolled by Ding Ding Ding Ding Industrial Co., Ltd., Henan Province. Ding Ding Industrial Co., Ltd., Henan Province (www.hnddsy.com) strong, credible, and other industries in other Anyang accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Dingding cold rolling and you hand into the brilliant, for a better future!
