What Actually Arrives With Your Order
Catalog sellers ship a ladder in a box. Every Dengtai order arrives as a documented access system — here is the complete manifest, item by item, as your receiving crew would check it in.
| In the Crate | What It Is | Why Your Inspector Cares |
|---|---|---|
| Pre-assembled, trial-fitted ladder | bolts aligned at the factory, photographed | no site rework — install is hours, not days |
| Declaration of Conformity | cites OSHA 1910.28 / EN ISO 14122-4 / BS 4211 / AS 1657 — your choice | the compliance citation your audit asks for |
| EN 10204 3.1 MTC | mill certificate for every heat of steel | photos archived for 10 years |
| Structural calculation sheet | engineer-signed for your project loads | proof the 1.5 kN/rung rating is engineered, not claimed |
| HDG coating report | ISO 1461, 85–100 μm measured on your parts | your long-term corrosion budget, documented |
| Anchor plan & torque sheet | M12 layout matched to your substrate | a two-person crew installs with hand tools |
| Loading photos | your exact lot, photographed at container | claims evidence before it ever sails |
Every item above is included at every price point — from a single 3 m ladder to a 24-unit container program. No line item for paperwork, ever.

Who Factory-Direct Fits — And Who It Doesn't
We would rather lose a mismatched order than win one that fails your expectations. Three honest checks before you send us an RFQ.
Buy factory-direct if…
- you can plan 15–25 working days + sea freight
- your climb needs custom height, exit or standard — or volume pricing at 10+
- your crew can bolt-to-install (or your installer accepts our anchor plan)
- documentation matters: audits, tenders, insurer questions
Buy local catalog instead if…
- you need it on site this week — stock beats specification
- your climb matches a catalog size exactly and volume is 1–2 units
- you require a local installer's warranty on labor, not just product
Expect to pay 2–3x for that convenience — US catalog $1,325–7,400 vs our $600–900 ex-works at 6 m. Both are fair deals for different buyers.
| What You Get | The Advantage | Your Outcome |
|---|---|---|
| One factory, every configuration | 2–20 m+, HDG/SS304/316/aluminium/GRP, four standards | one supplier for the whole site, one QC file |
| 24h engineer-reviewed quote | free CAD proposal before you commit a dollar | budget numbers you can take to procurement same-week |
| Full compliance manifest | DoC + MTC + calcs + coating report included | audit-ready from day one, decade of traceability |
| 500+ projects, 50+ countries | water, petrochem, power, food programs shipped | your application has been built here before |
