Metal Cat Ladder Materials Compared

Choose the right grade for your site. Every metal cat ladder is cut, welded and finished in our Shijiazhuang plant, and every grade ships with an MTC 3.1 material certificate traceable to the heat number. Tell us the environment — we'll spec the grade in your 24-hour quote. Specifying the wrong material for the atmosphere shows up as coating failure within the first inspection cycle.

Talk to a Material Engineer

Hot-dip galvanized steel cat ladder material on the factory floor

Q235B HDG Steel

HDG steel ladders with 85–100 µm zinc to ISO 1461. Best value in dry to moderate outdoor exposure; the standard choice for most roof, tank and plant walkway installations.

SS304 Stainless

18/8 austenitic for coastal, food-grade and washdown sites. mill-certified for grade traceability, acid-pickled finish — no coating to maintain.

SS316 Marine

2.5% molybdenum resists pitting and crevice corrosion in chloride, chemical and marine splash zones — the choice for offshore and process plants.

Aluminium & GRP

6061-T6 aluminium for weight-critical access; GRP/FRP for corrosive process plants and electrical areas where non-metallic, non-conductive is required.

Metal Cat Ladder FAQ

What materials are available for a metal cat ladder?

A metal cat ladder can be built in Q235B hot-dip galvanized steel (HDG 85–100 µm to ISO 1461), SS304 or SS316 stainless, aluminium, or GRP/FRP. HDG steel is our standard for roof, tank and plant walkway access; stainless and GRP are specified for marine, chemical and food-grade sites. Every grade ships with an MTC 3.1 material certificate.

What is the difference between HDG and stainless steel cat ladders?

Hot-dip galvanized steel gives the best cost-to-corrosion value for dry to moderate outdoor exposure, with a sacrificial 85–100 µm zinc coating per ISO 1461. Stainless SS304/SS316 is specified where chloride, chemical or washdown exposure would attack coating cut-edges and is mill-certified for grade traceability. Send your site environment and we confirm the right grade within 24 hours.

Can I get a steel cat ladder with cage?

Yes. Steel cat ladders with cage are fabricated to OSHA 1910.28 and EN ISO 14122-4, with safety hoops spaced at ≤1500 mm and a 1.5 kN rung rating. Cage hoops can be supplied in HDG steel, stainless, or an anti-slip GRP back hoop for process plants. Maximum single section is 25 m; taller climbs use rest platforms.

Do metal cat ladders come with compliance documents?

Every metal cat ladder order ships with a Declaration of Conformity (OSHA, BS 4211, EN ISO 14122-4), an MTC 3.1 material certificate, and engineer-signed structural calculation sheets — at no extra cost.

What is the minimum order for a metal cat ladder?

Trial orders start from 1 unit — a single caged run on one roof often opens a multi-site program. Container mixes of ladders, cages, gates and brackets are quoted per load plan, so staged orders combine into one container instead of paying for half-empty shipments.

Do rung spacings differ between OSHA and EN standards?

They do. EN ISO 14122-4 and BS 4211 call for rung spacing in the 225–300 mm band and we build 225–230 mm as standard; OSHA permits 254–356 mm. Name your governing standard in the RFQ and the jig is set to it, with spacing recorded on the drawing.

Which metal grade should we choose for a coastal site?

For marine and coastal chlorides, SS316 is the specified grade; aluminium 6061-T6 also performs well where weight is limited. Q235B HDG at 85–100 µm serves inland and general industrial sites. Send the site atmosphere and we confirm the grade in your 24-hour quote.

Can we order replacement rungs and brackets later?

Yes — spare rungs, brackets and gates are available in the grade and finish of the installed ladder, from HDG steel to SS316. They ride along in your next container or ship as a small LCL lot, quoted per load plan.
