AS 1163
AS/NZS 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
In AS/NZS 1163 grade designations, “L” indicates guaranteed impact properties, while “0” indicates a low-temperature impact test at 0°C. For example, C350 and C350L0 have the same nominal minimum yield strength, but C350L0 includes specified impact-performance requirements.

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.

FAQs
What is the difference between AS/NZS 1163 C350 and C350L0?
C350 and C350L0 have the same nominal minimum yield strength of 350 MPa and minimum tensile strength of 430 MPa. The difference is impact performance.
C350L0 has specified impact properties at 0°C, while ordinary C350 does not carry the same L0 designation. The applicable testing or verification route can depend on the section thickness and the provisions of the standard.
If a drawing specifies C350L0, it should not be changed to C350 without the project engineer’s approval.
What do “L0” and “L4” mean in AS/NZS 1163?
They refer to different requirements.
In a grade such as C350L0, “L” indicates guaranteed impact properties and “0” indicates a test temperature of 0°C.
L4 appears in the non-destructive examination provisions associated with ISO 10893-2. It is an NDE acceptance level, not a steel grade or a separate “L-grade weld seam.”
AS/NZS 1163 does not classify hollow sections as “Grade L” and “Grade H.”
Does every AS/NZS 1163 order require ACRS certification?
No. Whether ACRS certification is required depends on the project specification, tender conditions and customer approval process.
When ACRS is specified, checking the certificate name alone is not enough. The buyer should verify the manufacturing company, production location, product type, applicable grade and current certificate scope.
PANDAPIPE can provide the relevant certification details for review where ACRS documentation is required. The scope should be confirmed against the exact products in the order before purchase approval.
What projects use AS/NZS 1163 structural hollow sections?
AS/NZS 1163 CHS, SHS and RHS are commonly specified for building frames, columns, trusses, supports, industrial structures, bridges and general engineering fabrication in Australia and New Zealand.
The standard defines the product requirements, but it does not select the correct section for the project. The grade, dimensions and wall thickness must still be determined by the responsible engineer according to the design loads, service conditions, fabrication method and project specification.
What information is needed for an AS/NZS 1163 quotation?
A quotation-ready RFQ should include:
- Standard edition and complete steel grade
- CHS, SHS or RHS profile
- Outside dimensions and wall thickness
- Random, mill or fixed length
- Quantity by size
- Black or galvanized surface
- Cutting, drilling or other processing
- MTC, ACRS and inspection requirements
- Destination port
- Required delivery date
Attach the material schedule or drawing when possible. PANDAPIPE can then check the specification, production route and documentation requirements before preparing the quotation.
