Expertise
Real product knowledge for coastal conditions. Specs, guides, and compliance — so you get it right the first time.
Spec it once.
Spec it right.
The Sunshine Coast sits almost entirely within AS 3566 corrosion zones Class 3 to 5. NCC 2025 has tightened requirements. Chain of responsibility means everyone in the supply chain carries liability — with penalties that run well into six figures.
That's why no fastener leaves our counter on a guess. We spec the correct class for your zone, check galvanic compatibility, and put it in writing when you need it. Specced right, documented, defensible.
Compliance Documentation
Spec documentation available with your order — fastener class, AS standard, zone suitability, galvanic compatibility notes. Just ask, and file it with your QA records.
Galvanic Compatibility Check
Proactive at the counter. We flag bi-metal corrosion risks before product leaves the shop — not after it fails on site.
Spec My Job Service
Complete fastener specification for any job — correct class, head type, material compatibility, quantities per m². Delivered as a written spec sheet.
Knowledge that keeps you compliant
Practical guidance on corrosion classes, material selection, and coastal building requirements.
What's Your Corrosion Zone?
Type your build address and see the AS 4312 corrosivity band it falls in — distance to surf and calm salt water, what it means for your fasteners, and the stocked lines that suit the zone.
Read the guide → AS 3566Corrosion Zone Compliance
The Sunshine Coast sits almost entirely within AS 3566 Class 3-5 corrosion zones. We'll help you select the right fastener class for every zone — so your build meets the standard, not just the price.
Read the guide → Fastener ClassClass 3 vs Class 4 Screws
When do you step up from Class 3 to Class 4? It depends on proximity to the coast, salt exposure, and material combinations. We break down the specs so you make the right call on site.
Read the guide → Stainless Steel304 vs 316 Stainless Steel
304 handles most environments. 316 handles marine and high-chloride exposure. The price difference is significant — here's when the upgrade is worth it and when it's not.
Read the guide → Bi-MetalGalvanic Corrosion Prevention
Different metals in contact accelerate corrosion. Bi-metal screws, isolation washers, and correct alloy pairing prevent the premature failures that cost you rework on site.
Read the guide → Fibre CementFC Screw Selection
Fibre cement requires specific fasteners — wrong screws crack the board, strip the frame, or corrode within months. We spec the correct screw for every FC application.
Read the guide → AnchoringChemical Anchoring Systems
Epoxy, vinylester, or hybrid — each chemistry has a purpose. Substrate type, load requirements, and cure time all drive the right selection. We'll spec the correct system for your application.
