What this class covers
ANZSIC class 2221 covers Australian businesses primarily engaged in fabricating structural steel components for buildings and engineering structures. These operations transform raw steel materials into finished or semi-finished products that form the skeletal framework of construction projects. The classification applies to manufacturing activities conducted in factory settings rather than on construction sites.
Typical businesses in this class include specialized steel fabrication workshops that produce components for commercial buildings, industrial facilities, bridges, and infrastructure projects. These operations typically work from engineering drawings to cut, bend, weld, and assemble steel into the specified structural elements. The classification focuses on the fabrication process rather than the final installation or erection of these components.
Examples of operations classified under 2221 include: a workshop producing custom steel roof trusses for residential developments; a manufacturing facility creating reinforcing mesh for concrete construction; a specialised fabricator making structural girders for bridge projects; a factory producing prefabricated steel scaffolding systems; and a metal works manufacturing perforated steel plates for architectural applications.
Primary activities in plain English
Businesses in this class typically engage in one or more of the following activities:
- Manufacturing fabricated structural steel components as ready-made parts for buildings and structures
- Producing prefabricated steel girders, joists, and rafters
- Creating welded steel reinforcing mesh for concrete construction
- Processing reinforcing steel rods from wire bar or merchant bar
- Fabricating prefabricated steel roof trusses
- Manufacturing prefabricated steel scaffolding systems
- Producing perforated steel plates
Exclusions and nearby codes
Several related activities are specifically excluded from this classification and fall under other ANZSIC codes:
The manufacture of complete steel-framed and clad structures such as prefabricated sheds and garages is classified under ANZSIC 2222 (Prefabricated Metal Building Manufacturing).
The erection or installation of completely prefabricated buildings (including those prefabricated off-site to a substantially complete state) falls under Division E (Construction) rather than manufacturing classifications.
The construction, including on-site assembly, of complete pipelines or steel towers is included in ANZSIC 3109 (Other Heavy and Civil Engineering Construction).
The erection, installation, or on-site fabrication of structural steel components for buildings or other structures is classified under ANZSIC 3224 (Structural Steel Erection Services).
Practical guidance
For Australian businesses operating in structural steel fabrication, correct ANZSIC classification is important for various regulatory and administrative purposes. When registering for an ABN, businesses should ensure they select the appropriate classification that matches their primary activity.
On tax returns and Business Activity Statements, businesses in this class should use Business Industry Code (BIC) 22210, which corresponds directly to ANZSIC 2221. This ensures consistent reporting across government systems.
Workers' compensation insurance premiums are typically calculated based on industry classification rates. Structural steel fabricators generally fall under manufacturing industry rates, which vary by state and territory. Businesses should verify their classification with their relevant state workers' compensation authority.
When applying for manufacturing grants or industry assistance programs, businesses may need to demonstrate their ANZSIC classification eligibility. Some programs specifically target manufacturing sectors, making correct classification important for access to potential support opportunities.
