Why Hot Dipped Galvanised for Cat Ladders

Hot Dipped Galvanised Cat Ladder Material Comparison

The finish that survives an exposed roof longest wins the budget. We compare the coatings we fabricate in-house — so you pick on corrosion protection, not marketing claims. Specifying the wrong material for the atmosphere shows up as coating failure within the first inspection cycle.

Hot dipping after fabrication means the entire welded assembly — rungs, stiles, brackets and bolt holes — is coated inside and out, where pre-galv strip leaves bare edges.

Hot Dipped Galvanised Cat Ladder FAQ

What does hot dipped galvanised mean on a cat ladder?
Hot dipped galvanising (HDG) immerses the fully welded steel cat ladder in a bath of molten zinc at about 450°C, forming a metallurgically bonded coating of 85–100 µm per ISO 1461. Unlike a painted or powder-coated finish, zinc is sacrificial: if a cut edge or weld is scratched, the surrounding zinc corrodes first and protects the steel, giving decades of exterior service life (see ISO 14713 guidance).
How thick is the zinc coating on a hot dipped galvanised cat ladder?
Post-fabrication HDG at 85–100 µm is substantially thicker than pre-galvanised strip. For aggressive coastal or chemical environments we offer an optional powder topcoat over the zinc. A coating thickness report ships with every order.
Is a hot dipped galvanised cat ladder OSHA, EN ISO 14122 and BS 4211 compliant?
Yes — hot dipped galvanised cat ladders are built to OSHA 1910.28 / 1910.23, EN ISO 14122-4, BS 4211 and AS 1657 with 1.5 kN rung load, 225–230 mm rung spacing and fixing centres at 1500 mm or less. Every order ships with a DoC, MTC 3.1 material certificate and engineer-signed structural calculations.
How much does a hot dipped galvanised cat ladder cost and how fast do you quote?
A 6 m hot dipped galvanised cat ladder with safety cage and hinged gate is quoted per configuration, factory-direct ex-works — far below US catalog prices for the equivalent unit. We return an itemized factory quote within 24 hours; production runs 15–25 working days from approved drawing.
Can you build custom heights and configurations?
Custom heights are engineered to your drawing — single runs up to 25 m with rest platforms above, in knock-down or assembled sections. The drawing review is free within the 24-hour quote, and the coating report follows the finished geometry, not a catalog length.
Can we order spare parts in the same finish?
Yes — spare rungs, brackets and gates are available and hot-dip galvanized with the same 85–100 µm coating run, so replacement parts match the installed ladder. Standard items are listed in the accessory parts range; they pack into your container or ship LCL, quoted per load plan.
Why is hot-dipping after fabrication better than pre-galvanised strip?
Pre-galvanised strip carries a much thinner barrier that chips and rusts through at damaged spots. We fabricate the Q235B ladder completely, then immerse it, so welds, drillings and cut edges carry the full 85–100 µm coating per ISO 1461 — sacrificial zinc where scratches happen.
What maintenance does a hot dipped galvanised ladder need?
Very little — zinc corrodes sacrificially, so scratches self-protect rather than spread rust. Decades of service life follow the exposure class under ISO 14713 guidance, and touch-up zinc at cuts and welds covers deep scars. The coating report issued per order gives your inspections a measured baseline.
