The straight thread metal fiber of the steel bar processed by it is continuous and dense, and the comprehensive mechanical properties are good. The tensile strength is increased by 20%-30%, the fatigue strength is increased by 40%-60%, and the corrosion resistance is increased by 50%-200%.

The steel rolling straight thread connection technology is suitable for industrial and civil buildings, and it is required to make full use of the strength and ductility of the steel for the connection construction of the rigid, oblique and horizontal steel bars in important parts of the structure. It has a simple and fast process, can be prefabricated, has no open flame operations, does not pollute the environment, has no hidden dangers of explosion and fire, is safe and reliable, can be constructed around the clock, and saves a lot of steel and energy. Connect the bars with only a wrench, about one minute per bar joint. The construction period of the structure is shortened, and the industrialized and civilized construction is realized.

The steel wire rolling machine has a novel design, advanced technology, light, and flexibility. The operation is simple, the degree of automation is high, and the straight thread is formed by stripping and rolling at one time. The thread profile is of good quality and high precision, and the length of the straight thread is the same as that of the specification.

Reinforcing bar thread rolling machine can directly roll and process ordinary bars HRB335, HRB400, RRB400~ bars with specifications such as Φ12, Φ14, Φ1 6, Φ1 8, Φ20, Φ22, Φ25, Φ28, Φ32, Φ36, medium 40, etc. Pretreatment of steel bar upsetting and rib stripping can directly process regular threads.
