As a cold blender manufacturer, as well as a professional manufacturer of precision cold-bending sections, Sinowa can provide comprehensive precision steel profiles and systematic solutions for the partitions, doors and windows, and curtain walls covering all fields. Based on the low-cost advantage of China, it can offer most valuable system products, possessing competitive edge.

The precision cold-formed profile production line independently designed and developed by Sinowa has its own intellectual property rights and exquisite design, which realizes the co-production of a multitude of profiles with outstanding utility.

Compared with other traditional building materials, steel profiles have excellent mechanical forces.

First of all, as an important mechanical feature of structural steel, high yield strength can form an ideal elastic-plastic model within a large deformation range; secondly, due to a larger stress value, the steel has a larger residual deformation after yield, exceeding the normal range. The tensile strength guarantees structural safety; thirdly, elongation ratio is the plastic deformation of steel before fracture, which makes the steel become partially yield without obvious failure even by shearing, stamping, bending and hammering; fourthly, resisting to impact load, impact toughness is measured by the total absorbed energy during fracture, thereby it is a comprehensive indicator of steel strength and plasticity.

Besides its mechanical advantages, cold bending process maintains the physical properties of the steel, thus preserving the above prominent features.

A multiple times of cold bending can also greatly improve the strength and shear resistance of steel to meet the high specification requirements for materials in the building.

Based on the updating and optimization of market maturity, a series of precision doors and windows, partition and curtain wall profiles by Sinowa has relatively sound and compact structure with coordinated appearance. A number of innovative and marvellous upgrades endows predominant quality. Anti-counterfeit campaign and continuous innovative R&D make products take the lead in the forefront of the world.
