The Dengtai Story
Our Story Since 2004
One category, one focus, two decades. Dengtai Staircase Manufacturing Co., Ltd. began in the Jingxing Mining District of Shijiazhuang with a narrow brief: build steel fixed ladders and caged ladders that survive industrial duty.
That focus never changed. No side product lines, no spread — every production line, every weld station, every QC record is about one thing: a fixed ladder you can specify with confidence.

2004
Founded in Shijiazhuang, Hebei
Dengtai starts in the Jingxing Mining District with a single category: steel fixed ladders and cage ladders for industrial and municipal access.
-
2004 – 2015
Building the Single-Category Shop
Two production lines, 14 weld stations, a 25-strong team of designers, QC staff and fabricators — all focused on one product family, not ten.
-
2015 – 2020
Export Discipline
Export packing standardised (VCI rust protection, ISPM 15 heat-treated crates), Incoterms expanded to EXW / FOB / CIF, and the first 50+ country project base built.
-
2021 – 2025
A Documented Track Record
23 representative projects across 15 countries — water, power, industrial and food — each with an order-level Declaration of Conformity.

One Focus: Fixed Ladders
We do not build stairs, platforms or handrail packages to fill a catalogue. The whole factory exists for fixed ladders — and that is why spec quality stays consistent order after order.
Three Core Materials
Q235B galvanized steel, SS304 and SS316. If a project needs duplex or engineered load ratings, we source and certify to spec.
All configurationsCompliance in the DNA
Every ladder ships against OSHA, BS 4211, EN ISO 14122-4 or AS 1657, with order-level DoC, MTC 3.1 and structural calcs included free.
