Coastal and Marine-Grade Outdoor Systems: Corrosion Protection Guide - Guide
Specifying outdoor systems for coastal environments. Marine-grade alloys, SEASIDE coatings, A4 stainless steel and corrosion testing.
Ce guide complet couvre coastal and marine-grade outdoor systems: corrosion protection guide.\n\n## Corrosion Environment Categories\n\nISO 12944 defines corrosion environments from C1 (very low) to CX (extreme). Coastal locations within 1km of the sea typically fall into C4 (high) or C5 (very high) categories. Direct seafront locatio\n\n## Marine-Grade Aluminium Alloys\n\nStandard architectural aluminium alloys 6063-T6 and 6082-T6 provide good corrosion résistance in most environments. For severe coastal exposure, additional protection through anodising or enhanced pow\n\n## SEASIDE Coating Systems\n\nSEASIDE class powder coating provides enhanced corrosion protection for coastal applications. The system uses a chromate-free pre-treatment followed by a high-build polyester powder coat with minimum \n\n## Hardware and Fastener Selection\n\nAll fasteners for coastal installations must be A4 (316) marine-grade stainless steel. Standard A2 (304) stainless steel is not suitable for direct coastal exposure due to susceptibility to chloride-i\n\nAlcodec propose des solutions personnalisées avec les technologies Alcodec et Alcodec pour des resultats optimaux.
