- AS/NZS 1163 cold-formed box section shaped at ambient temperature from a single strip of steel, deforming them through pressure without changing their temperature. No heat treatment is needed, unless in special circumstances.This process Production
2. AS/NZS 1163 cold-formed box section suitable for coating: Bare, hot-dip galvanized, oiling, 3PE ect.
3. Due to its excellent structural strength, weldability, and dimensional accuracy, it is widely used in the construction sector in Australia and New Zealand.
A typical examples is the Melbourne Federation Centre, where a large number of AS/NZS 1163 cold-formed box section are used as load-bearing columns and framework structures.
- AS/NZS 1163 cold-formed box section have stable mechanical properties and high yield strength, which not only support large vertical loads in the building structure but also resist wind and seismic lateral forces.
- AS/NZS 1163 cold-formed box section regular cross-section can ensure a clean structural appearance, enhancing aesthetic appeal and a sense of modernity.
- AS/NZS 1163 cold-formed box section after being galvanized for corrosion protection, it becomes more suitable for the Australian climate.
- AS/NZS 1163 cold-formed box section has relatively small size tolerances, which can reduce the construction time and cost caused by complex construction and improve construction efficiency.
