Common Uses and Sectors: Structural Steel Beams

Structural steel beams are ubiquitous in construction and can be used anywhere a strong horizontal support is needed. In home building and renovations, steel beams often serve as floor bearers, strutting beams, verandah supports, lintels above wide openings, or even roof rafters. They allow for open-plan layouts and support additional storeys in residential projects. In larger commercial and industrial builds, structural beams form the skeletal frameworks of warehouses, offices, and factories and support infrastructure like bridges and mezzanines.

A wide range of industries rely on structural steel beams. Edcon Steel has supplied beams for residential housing developments, retail and education buildings, and heavy industries like mining and defence projects. Builders and engineers appreciate the high strength-to-weight ratio of steel beams, which ensures safety and stability in multi-storey constructions and long-span structures. Structural beams provide the robust support needed to get the job done, from home DIY projects to large infrastructure works.

For more information, read our blog about Builders Steel. Additionally, the OneSteel guide for builders and owner-builders provides support in the design, sizing, and applications of structural steel beams for domestic and house building.

Frequently Asked Questions

Does Edcon Steel deliver structural steel beams outside of Sydney and Regional NSW?

Yes. We deliver across Sydney daily and throughout the Central West from our Bathurst and Orange stores. Outside NSW, we ship nationwide with trusted freight partners. Our online ordering system and variety of freight options make it easy to get steel beams wherever you need them. We also offer Click & Collect from any of our NSW stores if you prefer to pick up in person.

Can I pick up my order in-store?

Yes. Use our free Click & Collect service from Brookvale, Revesby, Blacktown, Bathurst or Orange. We’ll prepare your order and notify you when it’s ready for pickup.

Where can I buy structural steel beams in Sydney?

Visit Edcon Steel in Brookvale, Revesby or Blacktown, or shop online 24/7 for delivery anywhere in Sydney.

What sizes of structural steel beams can I buy?

Edcon Steel supplies structural beams in a wide range of sizes. We stock standard Universal Beam sizes from roughly 150 mm up to 250 mm deep in-store, which covers many residential and light commercial needs. Larger beam sizes (up to ~610 mm depth) are also available by special order, so we can accommodate heavy structural requirements as well. All beams are cut to the exact length you need, so you don’t have to buy more than necessary.

Can I get steel beams cut or drilled to my specifications?

Absolutely. Edcon Steel specialises in custom cutting and fabrication for steel beams. We will cut your beam to the precise length you require and can also perform services like drilling holes or welding on cleats, end plates, brackets, and other components as needed. Simply provide your measurements or drawings, and our fabrication team will take care of the rest. This saves you time on-site and ensures the beam fits perfectly when you receive it.

What finish or coating should I choose for my steel beam?

That depends on the environment. For indoor use or dry environments, the standard mill finish (raw steel) is often sufficient (though applying a primer can offer basic corrosion resistance). A hot-dip galvanised coating is recommended for outdoor or exposed structures, especially in coastal or humid areas, to protect against rust and weathering. We can arrange to have your beams primed or galvanised on request – just let us know your preference when ordering. If unsure, our team can advise on the best protective coating for your project’s conditions.

What is the difference between an “I-beam” and an “H-beam”?

In practice, “I-beam” and “H-beam” refer to the same type of structural steel beam. These terms describe the shape of the beam’s cross-section viewed from the end, which resembles the letter “I” (a central web with top and bottom flanges). Some people use “H-beam” to describe a heavier or wider-flange profile, but in Australia, the standard term is Universal Beam (UB) for all these profiles. So whether you ask for an I-beam, H-beam, UB, or even an RSJ (Rolled Steel Joist), you’re generally talking about the same product. Edcon Steel will understand what you need, no matter which term you use.

Are Edcon’s steel beams certified to Australian standards?

Yes. All our structural steel beams meet Australian Standard AS/NZS 3679.1 for hot-rolled structural sections. We primarily stock Australian-made steel and can provide material test certificates upon request to verify compliance. Our beams have a minimum yield strength of 300 MPa (Grade 300) and are manufactured to rigorous quality requirements for structural use. When you buy from Edcon Steel, you can be confident you’re getting genuine, certified steel suited for Australian building conditions.

Can I buy only one steel beam for a small project?

Definitely - we have no minimum order quantity. Edcon Steel caters to DIY enthusiasts and one-off projects as well as large commercial jobs. You can order exactly what you require if you just need a single beam (or a few). We’ll cut it to size and even deliver it to you. Our goal is to help you get the job done, no matter how big or small the project.
