AS 1163

AS 1163 (AS/NZS 1163) is one of the Australian/New Zealand steel pipe standards. The standard specifies the size/shape/strength/chemical composition of the steel pipe.AS 1163 standard steel pipe, which is mainly used in building and engineering construction, has high strength and durability.
PANDAPIPE specializes in the production and supply of steel pipes conforming to AS/NZS 1163.To achieve good structural integrity, the production process combines cold forming and resistance welding techniques, and a wide range of sizes are carefully designed and manufactured to meet the needs of different projects.

AS/NZS 1163 Standard steel grade

AS1163 C250

AS 1163 C250 has a minimum yield strength of 250 MPa. It is generally used in buildings, supporting frames, etc. and is a relatively low strength grade of AS 1163.

AS 1163 C350

AS 1163 C350 has a yield strength of 350 MPa. It is used for building structures, bridges, support frames, etc., where medium strength and durability are required.

AS 1163 C450

AS 1163 C450 indicates a minimum yield strength of 450 MPa for this tube. Higher strength and durability for structural applications with higher loads and challenging environments.

AS 1163 C250L0/ C350L0/ C450L0

 L0 is the state without special conditions, i.e. without special heat treatment applied. Tubes of this standard generally have a standard chemical composition and mechanical properties.

Chemical/ Physical Properties of AS 1163

Chemical Requirements of AS/NZS 1163

The materials used in our production of AS/NZS 1163 steel pipes are strictly screened to ensure that they meet the high standards of chemical requirements. This strict material selection method gives the steel pipe excellent durability, strength and resistance to environmental erosion. In the production process, we have carried out strict control of the chemical composition of the steel, each steel pipe has gone through a fine manufacturing process, and fully meets the chemical requirements specified in the AS/NZS 1163 standard. It is our extreme attention to detail that enables our products to show outstanding performance in a variety of complex conditions.

Mechanical Requirements of AS/NZS 1163

The mechanical properties of the AS/NZS 1163 steel pipe are particularly critical. During the production process, we ensure that each pipe meets the parameters of tensile strength, yield strength and elongation AS/NZS 1163. Ensure the bearing capacity and stability of each steel pipe.

Shape of AS/NZS 1163 Standard Steel Pipe

The standard AS/NZS 1163 specifies several common shapes of steel pipes, including round, square and rectangular.

Round steel pipe: Round steel pipe smooth section, easy to connect and install, suitable for a variety of structural projects, because it can evenly distribute pressure, ensuring strong compression and bending resistance.

Square steel pipe: with a regular square cross-section, square steel pipe is convenient for positioning and fixing, and its excellent torsional and flexural properties make it perform well in occasions where lateral forces are required.

Rectangular steel pipe: the length and width can be flexibly adjusted according to actual needs to meet diverse design needs, especially suitable for structural systems that need to withstand specific directional forces.
