Inside a supply run
From cutting list to crane truck: how a re-roof package leaves on time.
It starts with a cutting list — profile, colour, lengths to the millimetre. The quote comes back within two business hours with a firm price and a dispatch window, not a guess. Custom-cut sheets only go to production once the list is signed off.
Long-sheet loads ride with carriers equipped for them. Flashings, fasteners, sarking and ridge capping travel on the same docket, so the crew is not waiting on a second delivery to start. The docket matches the order; the invoice matches the docket.
That is the whole promise: material that turns up when the job needs it, correctly specified, with the paperwork your certifier asks for.
Shop by category
Nine ranges. The whole envelope.
Roofing through to purlins — every range carries pricing where available, with custom and volume orders quoted by the trade desk.

Trade accounts
Run your supply like a procurement system.
A CSA trade account is more than a discount. Pricing, quotes, orders, invoices and job references live in one portal — built for crews where more than one person buys.
Account pricing
Approved trade accounts see their account pricing applied when signed in to the portal, with volume pricing reviewed for the lines you buy on repeat.
Saved lists & re-ordering
Save recurring material lists against your account, then re-order the same schedule for the next job without re-keying every line.
Quotes that convert to orders
Accepted quotes carry straight into orders — products, lengths and colours move from quote to purchase without retyping.
Invoices & statements
Tax invoices and account statements live in the portal, attached to the right order and job reference, ready for your accounts team.
PO references at checkout
Add your purchase order number at checkout so it follows the order through confirmation, delivery docket and invoice.
Multi-user access
Add estimators, supervisors and accounts staff to one trade account so ordering and approvals are not stuck with one person.

Construction supplies in Australia
Building materials and trade supply, starting with the envelope
Construction Supplies Australia is a trade supply specialist for builders, contractors, owner-builders and commercial projects across Australia. The first catalogue category focuses on the building envelope: steel roofing, walling, facade products, flashings, rainwater systems, fixings, insulation, ventilation, battens and purlins.
Current catalogue
Our catalogue includes the four major Australian steel brands — BlueScope COLORBOND, Lysaght, Stramit and Fielders — across products Australian builders already specify: corrugated iron, TRIMDEK®, Spandek, Klip-Lok 700, Monoclad®, Longspan®, flashings, gutters, downpipes, screws, sarking, insulation and structural sections.
More than a roofing shop
Roofing and facade products are the first category because that is where CSA has supplier depth today. The business direction is broader construction supply: the same catalogue, quoting, account and delivery model will be extended into additional building-material categories so trade buyers can source more of the job through one account.
Order online or request a quote
CSA is built around how the building trade actually buys. Standard catalogue products, lengths, fasteners and accessories can be ordered online with availability confirmed at acceptance. Custom-cut materials, mixed-category orders and full commercial project supply are quoted with a firm lead time and the NCC and Australian Standard compliance documentation that engineers and certifiers require. Trade account holders receive volume pricing, 30-day terms and priority processing.
Specified for Australian conditions
Every product we supply is specified to suit Australian conditions: corrosion-rated fasteners for coastal sites under AS 3566, non-combustible steel for bushfire-prone BAL zones tested to AS 1530.1, wind-rated fastener schedules under AS/NZS 1170.2, and NCC Section J thermal documentation for commercial buildings. The current steel range complies with AS 1562.1 where applicable and is made from steel manufactured to AS/NZS 1397. Whether you are ordering a roof package, cladding a city apartment block, fitting out a shed or sourcing job essentials, CSA aims to supply the right product, correctly specified, delivered on time.
Common questions
Buying construction supplies, answered.
Does CSA sell construction supplies online?
Yes. CSA is an online construction-supply shopfront for trade buyers. The current catalogue focuses on building-envelope steel, cladding, flashings, rainwater, fixings, insulation and related job essentials. Broader construction material categories will be added as supply lines come online.
Can I open a trade account for recurring projects?
Approved builders, roofers, facade contractors, owner builders and procurement teams can apply for a trade account. Accounts can support quote history, project references, repeat ordering, volume pricing discussions and net-30 terms where credit approval is granted.
Do you deliver outside Brisbane?
Yes. CSA arranges delivery through an Australia-wide freight network, including long-sheet and bulky construction material carriers. Delivery timing depends on product length, quantity, location, supplier availability and whether the order is a standard catalogue line, cut-to-length or project-specific.
Can CSA help with custom lengths and flashings?
Yes. For products that require custom length, project colours, fabricated flashings or bundled supply, submit a quote request with drawings, takeoff quantities or a product schedule. The trade desk will review the details before confirming availability and lead times.
Is CSA only a roofing supplier?
No. Roofing and facade products are the first catalogue category because that is where CSA has supplier depth today. CSA is positioned as a broader construction-supplies business, with additional building materials and trade categories planned as the catalogue grows.
