The annealed steel pipe need soft performance to be bent or shaped; so the steel strip material have to be annealed in good quality after cold rolled.

Processing mode: Hot-rolled or cold-drawn
Surface: Varnish coating or according to customers' demand
Ends: According to clients' required

In the construction, building and structure of the industry, the key to success is its stainless steel with good corrosion resistance
