Corrosion Protection Standards
Building codes worldwide link fastener corrosion protection to the corrosivity of the site and the required service life. These are the main references our customers specify.
International (ISO)
- ISO 9223 / ISO 12944-2
- Atmospheric corrosivity categories, from C1 (very low) to C5 (very high) and CX (extreme).
- ISO 4042
- Electroplated coatings on fasteners, including hydrogen-embrittlement control for high-strength parts.
- ISO 10684
- Hot-dip galvanized coatings on fasteners.
Europe (EU)
- CPR (EU) 305/2011
- CE marking and Declaration of Performance for construction products covered by harmonised standards.
- EN 1993-1-4
- Corrosion resistance classes CRC I – CRC V for stainless steel.
- EN 14592
- Dowel-type fasteners for timber structures.
United States (US)
- IBC / IRC R317.3
- Fasteners in contact with preservative-treated wood must be hot-dip galvanized, stainless steel, silicon bronze or copper. Mechanically galvanized coatings to ASTM B695 Class 55 are permitted for some fasteners.
Australia & New Zealand
- AS 4312
- Atmospheric corrosivity zones.
- AS 3566.2
- Corrosion resistance classes for self-drilling screws.
- AS/NZS 2312 / AS/NZS 4680
- Protection of structural steel and hot-dip galvanized coatings.
Our Corrosion Protection
Proven options, matched to the corrosivity of your site and the service life your project requires.
Zinc Plated
AS 3566 Class 2
Yellow passivated zinc for interior and protected applications such as framing, chipboard and plasterboard.
HDG
Structural bolts & anchors
Thick zinc coating for AS 1252 structural assemblies, anchors and exposed steelwork.
Zinc-Flake Coating
1,000 h ASTM B117
Salt-spray tested with no red rust. Applied without an electrolytic process, so there is no process-induced hydrogen embrittlement in high-strength fasteners.
A2 (304)
ISO 3506 A2-70
Grade 1.4301, classed CRC II under EN 1993-1-4. For exterior and general building applications.
A4 (316 / 316L)
CRC III · EN 1993-1-4
Grades 1.4401 and 1.4404 for coastal, high-chloride and severe environments.
EN 10204 3.1 and 3.2 material certificates available for every order. Tell us the corrosivity category, applicable code and service life your project requires, and our engineers will recommend the right coating or grade. Final selection should always follow the project specification and local building code.
Quality & Certification
Material Certification
EN 10204 3.1 and 3.2 material certificates, with third-party inspection by SGS, Bureau Veritas or TÜV on request.
