Core strengths

1. Direct shaping: Through precise control of multi-step cold bending, ultra thick steel plates are directly pressed into squares, solving the pain points of long-term dependence on inefficient processes or high priced imports.

2. Reduce costs: Eliminate the secondary processing of "round to square" to reduce intermediate links, improve material utilization, and reduce energy consumption and working hours.

3. Product performance: Achieve continuous production of large-diameter and ultra thick walled square rectangular pipes, with significantly better mechanical properties and dimensional accuracy than traditional processes.

Applicable scenarios

1. High rise steel structure and station construction.

2. Mechanical equipment, ship equipment.

3. Smart logistics, three-dimensional garage.
