Zinc Plated Cat Ladder for Roof Access: HDG Performance
Our zinc plated cat ladders are fabricated from Q235B carbon steel and finished with hot-dip galvanizing to ISO 1461 at 85–100 µm. The zinc coating protects cut edges, welds and bolt threads by sacrificial action — even if the surface is scratched, the exposed steel stays protected. It is the most economical corrosion finish for exterior roof access ladders exposed to rain, humidity and light chemical atmospheres. Specifying the wrong material for the atmosphere shows up as coating failure within the first inspection cycle.
- Sacrificial zinc protection
85–100 µm HDG per ISO 1461; scratches and cut edges self-protect
- Economical for roof access
Lower cost per metre of climb than stainless — ideal for roof and parapet routes
- Full traceability
MTC 3.1 certificate certifies the HDG steel batch to EN 10204 3.1
