An accurate steel frame quote starts with complete plans and site details, because wind class, spans, roof form and delivery all change the price. Send architectural drawings, your address and any engineering to a free quote request, then check the itemised pricing covers engineering, detailing and delivery. Comparing quotes like for like also protects you under QBCC contract and deposit rules.[42][43]

TL;DR

• Send full plans, site address and wind class if known

• Expect an itemised breakdown, not a single number

• Check engineering, detailing and delivery inclusions

• Compare supply only with supply only

• Know the QBCC deposit caps before you sign

Frametek gives clear upfront quotes with a breakdown of what is and is not included. Send your plans through our free quote form, read our pricing approach, see our services, check FAQs or contact us.

What to send with your quote request

The more complete your information, the fewer surprises later. Include floor plans, elevations, sections, roof pitch and cladding, and your site address so the supplier can assess the wind class under AS 4055.[27] Note whether you want wall frames, roof trusses, a floor system, rolled sections or fabricated steel.

Tell the supplier about your floor type, slope and any coastal exposure. YourHome explains slabs can be on ground, suspended or both, and that challenging slopes need careful design.[46][45] BlueScope classifies marine environments as surf, exposed or calm.[19] These details shape design, engineering, specifications, locations and project builder pricing.

What an itemised quote should include

A quote should name the steel and standard used. TRUECORE comes in G450, G500 and G550 grades to AS 1397, and NASH standards are the NCC’s deemed to satisfy path.[16][1] Eligible frames may carry a BlueScope warranty of up to 50 years, often with pre approval before construction.[20] Confirm compliance documents, downloads, manufacturing standards, supplier terms and installation help.

Comparing quotes fairly

Compare supply only against supply only, and check whether engineering, detailing, delivery and termite or thermal break items are priced. Steel always needs a thermal break, which affects other trades.[11] Steel is not subject to termite attack under the NCC, while susceptible timber elements need management.[21] Look at benefits of steel, manufacturers, project builder needs, owner builder pricing and renovation pricing.

Contracts, deposits and protection

QBCC requires a written contract for domestic work over $3,300.[42] Maximum deposits are 10 percent for $3,301 to $19,999 and 5 percent above $20,000, and QBCC lists made to measure items among off site work examples.[43] Most residential work over $3,300 needs home warranty cover.[40] Fixed price contracts support non completion claims under the scheme.[41] Check pricing, quote terms, services, contact details and FAQs.

Owner builders cannot access the home warranty scheme and need a permit above $11,000.[10] Certifiers inspect stages against approved plans.[38] Keep quotes, engineering, detailing, delivery dockets, compliance certificates and specs together.

Timing and lead times

Prefabricated wall frames and trusses can shorten timeframes and cut waste.[47] Lead times still depend on approvals and workload, so ask for a date. Brisbane City Council notes that new houses always need building approval.[44] Plan manufacturing, installation, delivery, design changes and project schedules.

Energy and code rules can change frame details late in design. Queensland adopted the NCC 2022 Modern Homes standards.[49] The QDC runs alongside the NCC.[61] Thermal break strips often need R0.2.[13] Lock details in with design, wall frames, roof trusses, floor systems and granny flat kits.

Common reasons quotes change after you accept them

Most price changes after acceptance come from design changes, not the frame supplier. Moving a window, changing the roof pitch, switching cladding or adding a deck can all alter member sizes, connections and engineering. The fix is simple: finalise the plans before asking for a firm price. Use our design service to settle details early, then confirm engineering, detailing, steel wall frames and roof trusses so the quote reflects the home you will build.

Site conditions are the other common cause. A steep driveway, tight backyard access or a change in wind class after a site assessment can affect delivery and design. Mention access limits, slope and the site address in your request so they are priced from the start.[45] Our delivery locations page, floor systems, steel house frames, granny flat frames and shed frames pages show what to include.

Finally, check that every quote you compare has the same scope. One quote may include engineering and delivery while another lists them as extras, and one may cover supply only while another includes installation. Put the line items side by side and ask questions before you sign a contract.[42] Read our pricing and quotes guide, FAQs, services, learn about Frametek and contact the team if anything is unclear.

Once you have chosen a supplier, confirm the delivery date in writing, check the order against the approved plans and ask who to call if something is missing on site. A short checklist at this stage prevents most delays. Our delivery locations, detailing, steel house frames, engineering and contact options pages explain what to expect.

Remember that the cheapest quote is not always the best value. A complete, clear quote from a supplier that answers questions quickly can save far more in time and rework than a small difference in price. Compare our steel frame suppliers, steel frame manufacturers, project builder supply, industries and design service pages as you weigh up your options.

Labelled scenario: two quotes that differ

Hypothetical example only: one quote excludes delivery and engineering while another includes both. The builder asks each supplier to restate engineering, delivery, detailing, installation support and warranty eligibility before comparing.[20]

Decision checklist

• Full plans and site address

• Wind class, or ask the supplier to assess

• Floor type and slope

• Coastal distance

• Products and standard named

• Engineering and detailing included

• Delivery and unloading

• Deposit within QBCC limits

FAQs

How long does a steel frame quote take?

It depends on plan complexity and workload; complete plans speed it up. See free quotes, pricing, services, FAQs and contact.

Can I get a quote without engineering?

Yes, the supplier can often assess the wind class and engineer the frame.[27] Ask about engineering, detailing, design, compliance and specs.

What deposit is normal?

QBCC caps deposits at 5 percent for most contracts over $20,000.[43] Review supplier terms, owner builder rules, project builders, renovations and developers.

Does the quote include delivery?

Always check; access affects cost. See transportation, locations, installation, manufacturing and projects.

Can I get a quote for frames only and arrange my own installer?

Yes, supply only quotes are common, and many builders and owner builders use their own installers. See owner builders, project builders, fabrication, steel frame suppliers and request a free quote.
