Why This Page Exists
Where Residential Steel Quotes Go Wrong
We talk to Melbourne residential builders every week. Same four complaints keep coming up about most fabricators. Here's the pattern — and what we do instead.
Slow, vague quotes
✕ Typical shop
Verbal estimates, no line items, ambiguous lead time. By the time you have the quote, you've moved on or your client has cooled.
✓ How 8 Star handles it
Send engineer drawings, get back a written quote with materials, labour, finish, delivery and lead time — every line itemised so you can see exactly what's costing what.
Lead time slips after deposit
✕ Typical shop
"Sorry, materials delayed", "had a bigger job come in", "we'll get to it next week". Your concrete cures, your trades stand around, your client gets the bill.
✓ How 8 Star handles it
Delivery date locked at quote stage with weekly progress check-ins. If anything risks the date, you hear about it before it slips — not after.
Shop drawings don't match engineer's
✕ Typical shop
Members get fabricated, arrive on site, and your engineer red-pens them. Rework on the truck, delay on site, fingers pointed everywhere.
✓ How 8 Star handles it
Stamped shop drawings issued to your engineer for sign-off. No steel gets cut until your engineer signs. Mismatches caught on paper, not on site.
No mill certs or welder records
✕ Typical shop
Building surveyor wants compliance documentation, fabricator can't produce mill certs, your handover stalls until something gets retroactively cobbled together.
✓ How 8 Star handles it
Mill certs, batch traceability, welder qualifications, weld inspection records — handed over with the steel. Whatever your certifier asks for.
Pricing Transparency
How Residential Steel Quotes Are Structured
Every quote we issue is broken into five line items so you can see exactly what you're paying for — and which line items move when scope or finish changes.
Material
UB / UC / PFC / plate / hollow sections — supplied to length, mill-certified, sized to the engineer's schedule.
Fabrication Labour
Cutting, drilling, coping, welding, connection details — the engineering hours that turn raw material into your specified members.
Finishing
Hot-dip galvanising, two-pack paint, mill finish or powder coat — line-itemed by finish spec, not bundled.
Delivery
Crane-truck delivery to your site — coordinated to your trade sequence. Tail-lift if site access is tight.
Install (Optional)
On-site erection with our crew — bolt-up, weld-out, hand-over to your carpenter. Or supply-only if you've got a crew.
Quote Faster
Information We Need for an Accurate Quote
Most quote back-and-forth happens because the fabricator chases for missing information. Send these upfront and we can lock in a quote without the back-and-forth.
Engineer-Stamped Drawings
PDF or DWG. Member schedule on first page if you have it.
Steel Schedule / Member List
Sizes, lengths, quantities. Even a rough takeoff helps.
Connection Details
Cleats, bolts, welds — engineer's preferred connection types.
Finish Requirements
Galvanise / paint / mill finish. Internal vs external members.
Site Access Notes
Crane-truck clearance? Narrow drive? Lift restrictions? Easement?
Build Program Context
Where does steel sit in your trade sequence? After concrete cure? Before brickwork?

Project Flow
How a Residential Steel Project Flows
Six stages, six artifacts exchanged. Each stage gates the next — nothing skipped, nothing assumed. The artifacts give you a clear paper trail at every step.
Stage 01
Drawings In
Engineer-stamped drawings arrive — PDF or DWG. We review structural scope, weldability and access.
Stage 02
Itemised Quote
Quote returned with materials, fabrication, finish, delivery and install line-itemed. Lead time and delivery date committed in writing.
Stage 03
Shop Drawings
Stamped shop drawings issued for your engineer's sign-off. Connection details, hole positions, member marks — checked before any cutting starts.
Stage 04
Fabrication
Cut, weld, drill, finish — in-house workshop. Welder qualifications match member class. Progress updates issued weekly while in fabrication.
Stage 05
Delivery
Crane-truck delivery to your site, coordinated to your trade sequence. Pre-delivery call to confirm slab readiness and lift plan.
Stage 06
Install & Hand-Over
On-site install with our crew (or supply-only to yours). Mill certs, batch numbers and compliance documentation handed over at completion.
Site Integration
Coordinating With Your Trade Sequence
Steel doesn't arrive in isolation. It lands into a build program that's juggling concrete cure, frame-up, brickwork and roof. Here's how we sequence with the trades that matter most on residential jobs.
Concreter
Steel goes in after slab cure or footing pour. We confirm slab readiness, anchor bolt positions and set-out marks with your concreter before delivery — we don't install steel onto green concrete.
Carpenter / Framer
Frame goes up around installed steel. We deliver with carpenter sequence in mind — beams accessible for fixing, and live members don't block frame paths.
Bricklayer
Lintels, exposed posts and structural beams sit at brick-course critical points. Member positions confirmed with bricklayer before site install — so there are no last-minute adjustments mid-course.
Roofer
Roof beams and structural members hand off to roofer for sheet, gutter and fall. Beam top heights and bolt-up details confirmed against roof spec before fabrication signs off.
Builder FAQ
Questions Melbourne Residential Builders Ask Us
Eight common questions. If yours isn't here, call 03 7064 0780 — we'd rather answer it before you quote out the job.
How are residential steel quotes structured?
Every quote is broken into five line items — material, fabrication labour, finishing, delivery and install (optional). You can see exactly what each component costs, which makes scope changes easy to price transparently.
How much does residential structural steel typically cost in Melbourne?
Cost depends on tonnage, connection complexity, finish spec and site access. We quote line-by-line so you can see exactly what's costing what. For an indicative budget on your specific job, send engineer drawings and we'll come back with a written quote.
Can I send hand sketches or do I need engineer drawings?
For a budget estimate, hand sketches work. For a binding quote with lead time committed, we need engineer-stamped drawings. If you're early in design, we can give you a budget number to feed into your client conversation and refine when engineer drawings come through.
Do you supply mill certificates with residential packages?
Yes — standard with every residential package. Mill certs, batch traceability and welder qualification records come with the steel. Your building surveyor and certifier will ask for these at handover.
What if my engineer changes the design after fabrication starts?
It happens. If it's a minor change before cutting, no problem — we re-issue shop drawings. If steel's already cut, we'll cost the variation upfront so you can decide whether to absorb, pass through, or negotiate with the engineer. Variations are priced against the affected line item, not bundled into the next invoice.
Do you install or just supply?
Both — your choice. End-to-end (supply + on-site install with our crew) is the default. Supply-only is available if you've got a crew lined up. We coordinate crane-truck delivery either way.
Can you fabricate around existing concrete or framing on a renovation?
Yes — extensions and renovations are core work. We can do a site visit before fabrication if dimensions are unclear or if you've got existing brick walls / concrete slab that fabrication needs to integrate with. Site measure included for tricky renos.
Can you work directly with my engineer for technical queries?
Absolutely — and we prefer it. RFIs and shop drawing sign-offs go direct between our drafter and your engineer, with you cc'd. Saves you relaying messages between parties and avoids info getting lost in translation.
