Dengtai Staircase Manufacturing Co., Ltd. is a Chinese steel ladder manufacturer founded in 2003 and headquartered in Shijiazhuang, Hebei Province. For over two decades, we have specialized exclusively in industrial fixed access equipment. We do not diversify — steel ladder manufacturing is our only business.
Who We Are
Operating from a 3,000 sqm factory with 25 employees — 20 production technicians, 3 engineers, and 5 international sales specialists — Dengtai has completed 500+ projects across 50+ countries. Our annual production capacity of 1,500 tonnes supports projects ranging from single-ladder orders to multi-container bulk shipments.
We are ISO 9001:2015 certified and manufacture to OSHA 1910.23, EN ISO 14122-4, BS 4211, AS 1657, and IS 3696. Every shipment includes full compliance documentation — material certs, weld inspection records, dimensional reports, and coating thickness measurements.
