Powder coating and galvanising are covered by recognised British and European Standards (BS EN / BS EN ISO) that define coating quality, durability, and corrosion protection. Following these standards ensures steel products perform reliably in outdoor environments.
Galvanising standards
- BS EN ISO 1461
Hot dip galvanised coatings on fabricated iron and steel articles- Defines coating thickness, finish quality, and inspection criteria
- Ensures full internal and external coverage
- Provides long-term corrosion protection, even in harsh environments
Powder coating standards
- BS EN 13438
Powder organic coatings for hot-dip galvanised steel products- Covers coating performance, adhesion, and durability
- Designed specifically for duplex systems (galvanised + powder-coated steel)
- Includes resistance to UV, weathering, and impact
Additional commonly referenced standards
- BS EN ISO 12944
Corrosion protection of steel structures by protective paint systems- Used to define environment categories (C1–C5) and expected lifespan
- BS 3900 (series)
Performance testing for paints and coatings- Covers coating behaviour, durability, and application testing
Practical takeaway
- Galvanising (BS EN ISO 1461) protects the steel from corrosion
- Powder coating (BS EN 13438) adds durability, colour, and extra protection
- Combined, they form a duplex system — one of the most effective finishes for long-term outdoor use
At Aremco Barriers, our steel products are hot-dip galvanised to BS EN ISO 1461 and can be powder-coated to BS EN 13438, ensuring a high-performance, long-lasting finish suitable for UK weather and demanding environments.
