Royal Steel Group supplies AS 1074 pipes with three wall thickness grades: Light, Medium and Heavy. Your proper selection needs to consider pipe dimensions, mechanical load, site installation environment and local service codes.
Light Series
This thin-wall grade can only be adopted when your design specification permits. It is not suitable for gas, water or pressure piping under regulatory control unless you verify full compliance with application standards and local codes.
Medium Series
This is the most widely used grade for general piping works, as long as dimensions and installation regulations are met.
Heavy Series
Featuring thicker walls, this grade is reserved for scenarios demanding higher wall strength, subject to design calculation and service requirements.
Key Note: Wall thickness alone cannot define a pipe’s allowable working pressure. Pressure rating must be evaluated comprehensively based on relevant design standards, pipe size, operating temperature, material performance and actual service conditions.
Royal Steel Group’s AS 1074 steel tubes cover multiple common application scenarios as outlined below.
Water Supply and Distribution
AS 1074 steel pipes can be used for water delivery systems, provided the selected pipe class, corrosion protection method, fittings and plumbing standards all meet project requirements.
Building Services
Qualified pipe variants work well for building utility systems and general mechanical installations, subject to compliance with local building codes.
Industrial Fluid Piping
These carbon steel pipes serve as a cost-effective piping choice for standard industrial fluid transfer. Projects with high operating temperatures, heavy pressure loads or hazardous media will need alternative or upgraded pipe specifications.
Agricultural and Infrastructure Projects
This steel pipe range is applicable to eligible utility, infrastructure and farm projects, as long as the design approves the selected material and pipe class.
Galvanized Steel Tube Applications
Hot-dip galvanized pipes feature a zinc coating to resist rust. When placing orders, please double-check coating quality, operating environment and required coating standards.
Royal Steel Group understands that reliable steel tube procurement requires clear specifications and consistent quality documentation.
Depending on the ordered product and applicable requirements, quality checks may include:
Dimensional inspection and wall-thickness verification
Visual inspection of the tube surface and ends
Verification of marking and product identification
Applicable mechanical or leak-tightness testing
Review of agreed inspection and material documentation
Confirmation of surface treatment and packaging requirements
The precise inspection and acceptance criteria depend on the applicable edition of AS 1074, the product configuration, and the purchase order. Additional testing should be specified before production.
Project-Focused Product Selection
Our team works with purchasers to lock down key details including nominal size, wall thickness, pipe end type, surface finish and certification requirements prior to issuing quotations.
Flexible Supply Options
Get in touch with our sales team to share your target dimensions, order volume and delivery location, and we will tailor suitable supply solutions for your project.
Clear Technical Communication
We can review your engineering drawings and purchase specs, minimising technical discrepancies during quoting, manufacturing and shipment stages.

Required inspection reports or material documentation
Providing these details helps our team evaluate product suitability and prepare a more accurate offer.
Q1: What does AS 1074 cover?
AS 1074 sets out requirements for ordinary-service steel tubes and tubular products. This standard covers both threaded pipes and plain-end pipes that can be threaded. It also defines three wall thickness classes across its size range: Light, Medium and Heavy.
Q2: Are AS 1074 steel tubes suitable for pressure applications?
Whether these pipes fit pressure service depends on your project and applicable design codes. Compliance with AS 1074 alone does not mean the pipe can be used for all pressure systems. Always verify design standards, operating conditions and local regulations before installation.
Q3: Are galvanized AS 1074 steel tubes available?
Hot-dip galvanized variants are available subject to pipe size and end configuration. When requesting a quote, please specify your coating needs and the galvanizing standard you require.
Q4: Can AS 1074 tubes be supplied with threaded ends?
The standard includes both threaded and plain-end pipe options. When placing your order, confirm thread style, end form and matching fittings to avoid mismatch.
Q5: What is the difference between Light, Medium, and Heavy tubes?
These classifications refer to different wall thickness values for each nominal pipe size. You must select the correct class according to your project design and service conditions; no single class works for all scenarios.
Q6: What details do you need to prepare a quotation?
To provide an accurate quote, please share pipe size, wall thickness class, length, order quantity, surface treatment, end type, intended use and delivery port. Also mention any special inspection or certification requirements for your project.
