What is a Structural Steel Supplier?
A Structural Steel Supplier provides fabricated steel beams, posts, brackets, and fixings that form critical load-bearing components of your residential build. These components are pre-cut, drilled, and often pre-primed based on engineering specifications.
They are usually delivered before framing begins and installed early in the structural phase of the build.


What does a Structural Steel Supplier do?
Your Structural Steel Supplier will complete works according to your agreed scope of works.
Typically, a Structural Steel Supplier will:
- Review your engineering drawings and structural specifications
- Provide a detailed steel takeoff (list of required beams, columns, and connections)
- Fabricate and prepare structural steel components to size
- Apply primer or galvanising as required
- Deliver materials to site in line with the framing schedule
- Supply compliance documentation and structural steel certificates
Install is usually done by your builder, carpenter, or a steel installer on-site.

Barry's Toolbox
Always ask your steel supplier to confirm whether their quote includes fixings and base plates. These are often left out, but without them, your steel can’t be installed.
What to look for in a Structural Steel Supplier
When reviewing quotes, look for:
- Detailed takeoff and quote: Includes beam lengths, angles, cleats, and any bracing
- Lead time accuracy: Steel delays can block framing and roof installs
- Coating options: Red oxide primer or galvanised depending on exposure
- Transport coordination: Must suit your site access and crane/lift requirements
- Compliance paperwork: Certificates of compliance and mill certificates on request
Before You Begin: What You’ll Need Ready
To get quotes from Structural Steel Suppliers, you’ll need:
- Engineering and architectural drawings (PDFs preferred)

- Site address and delivery access details
- Installation schedule (to coordinate delivery)
- Paint or finish requirements (e.g., primed, galvanised)
Average Timeframe
For this task, Pros typically provide quotes within
7-10 business days.
When Can I Expect Quotes?
Timeframes often vary based on demand and the type of Pro you're engaging (e.g. a plumber). If additional communication or clarification is needed is needed, the quoting process may take longer.
Don't be alarmed if you don't receive quotes or communication from any Build Buddy Pros straight away. Some work is more complex and the Pro may need time to comprehend your documents or scope of work. Depending on the job, there may even be some work required by the Pro before they are able to quote (e.g. a site visit might be required).
If the average timeframe indicated here has passed, and you have not received any messages or quotes, please feel free to contact the Build Buddy Expert Guidance and Support team for an update on quoting for this task.
Frequently Asked Questions
Do steel suppliers install the beams too?
No — most are supply only. Your builder, chippy, or a steel installer will coordinate erection on-site.
