Frequently Asked Questions

Can I get a ladder with custom dimensions not listed here?
Yes. Custom heights (any value, not just standard intervals), widths (e.g., 500mm for narrow access, 800mm for wide platforms), non-standard rung spacing, and custom surface treatments are all available through our custom engineering service. MOQ for custom dimensions is 5 units. Send your drawing or specification to sales@dtsteelladder.com for an engineering review within 24 hours. CAD drawings are provided for approval before production begins.

What does “per meter” pricing include?
The per-meter price includes: the ladder assembly (stiles, rungs), wall brackets, fixing hardware (SS304 anchor bolts), specified surface treatment (HDG, brushed, or passivated), compliance documentation package, VCI vacuum packaging, and wooden crate. It does not include: sea freight, destination customs duties, installation labor, or optional accessories (ladder safety systems, intermediate platforms, security gates, anti-climb shields).

How do I choose between HDG and stainless steel for my project?
For dry indoor and non-coastal outdoor environments, HDG Q235B offers excellent corrosion protection at the lowest cost ($23-30/m). For food-grade, pharmaceutical, or mildly coastal environments, choose SS304 ($61.50-77/m). For heavy coastal (<5km from saltwater), offshore, chemical processing, or water treatment environments, choose SS316 ($73-115/m). See the complete material selection guide for lifecycle cost analysis, including a 30-year coastal installation scenario where SS316 costs less than half of HDG in total ownership cost.

What is the difference between single-section and multi-section caged ladders?
Single-section ladders (2-6m) are one continuous piece, factory-assembled. Multi-section ladders (>6m, CL-HDG-MULTI) are fabricated in 3-6m sections that bolt together on-site at flanged joints. Multi-section configurations include intermediate landing platforms at 6-9m intervals per EN ISO 14122-4 section 4.3.2, with guardrails and self-closing safety gates. The per-meter product price is the same; the cost difference is from additional platforms and installation labor.

How do I get a complete specification sheet for a specific model?
Email sales@dtsteelladder.com or WhatsApp +86 155 1187 9488. Request spec sheets for specific models (e.g., “CL-HDG-STD and CL-SS316-STD specification sheets”) and we will send the PDF within 24 hours. For multi-model project submittals, we can compile a consolidated specification package.
