65Mn Cold Drawn Ribbed Spring Steel Bar For Construction

Cold drawn ribbed spring steel bar is a steel bar with two or three crescent shapes formed by hot-rolled wire rod through multiple cold-rolling reductions, one rib pressing and internal stress relief. In prestressed concrete components, cold-drawn high carbon spring steel bar is an updated product of cold drawn low carbon steel wire. In cast-in-place concrete structures, it can replace grade I steel bars to save steel. It is a better cold-processed steel of the same kind.

Classification

1) According to the chemical composition classification
According to GB/T 13304 standard, spring steel is divided into non-alloy spring steel (carbon spring steel) and alloy spring steel according to its chemical composition.
①Carbon spring steel
②Alloy spring steel
In addition, some brands are selected as spring steels from other steels, such as high-quality carbon structural steel, carbon tool steel, high-speed tool steel and stainless steel.

Feature

1)The strength of the ribbed spring steel rebar is high, which can save construction steel and reduce the cost of engineering.
2)The bonding and anchoring performance between cold -rolled rib steel and concrete is good. Therefore, it is used in the component, which fundamentally eliminates the phenomenon of cracking, steel wire slippery, and improving the bearing capacity and cracking ability of the component; in the reinforced concrete structure Reinforced steel, even smaller than hot -rolled threaded steel bars.
3)The elongation of cold -rolled ribs is larger than the same cold processing steel.

Application

Cold-rolled ribbed 65Mn spring steel bar have been widely used in construction projects, highways, airports, municipal and hydro-power pipelines. For example, 65Mn cold-drawn ribbed spring steel bar can be used for making welded mesh, which is suitable for highway pavement, airport runway, large-diameter drainage pipe, drainage channel, tunnel, etc.

Application

As China metal materials industry leading enterprises, the national steel trade and logistics "Hundred good faith enterprise",China steel trade enterprises, "Top 100 private enterprises in Shanghai”. Shanghai Zhanzhi industry Group Co., Ltd.,(shorted to Zhanzhi Group) takes the" Integrity, Practicality, Innovation, Win-Win " as its sole operation principle, always persist in putting the customer demand in the first place.
