Frequently Asked Questions
25+ years in typical industrial environments (C3). 15+ years in coastal/marine (C4). Much longer than painted finishes at similar cost.
HDG is more cost-effective for most outdoor applications. Stainless is necessary only for direct chemical exposure or food-grade requirements. For \tropical climates, HDG is usually the right choice.
The zinc coating adds approximately 85μm per surface. This is accounted for in our fabrication tolerances — your ladder will fit as specified.
