Frequently Asked Questions
What is the minimum order quantity for steel ladders?
Standard models: 1 unit. Custom-engineered ladders: 5 units minimum. This is one of the lowest MOQs in the Chinese steel ladder manufacturing industry. Most competitors require 10-20 units.
What payment terms does Dengtai accept?
Standard terms: T/T 30% deposit with 70% balance before shipment. For orders exceeding $10,000, L/C at sight is available. We do not accept D/A or open account terms for first-time buyers.
How long does delivery take?
Standard models ship within 15-20 working days of order confirmation. Custom or bulk orders require 30-45 working days. Ocean freight transit adds 15-35 days depending on destination.
What compliance documentation is provided?
Every order includes: Certificate of Origin (CCPIT-issued), Commercial Invoice, Packing List, Bill of Lading, material certificates (EN 10204 Type 3.1), weld inspection reports (ISO 5817), coating thickness reports, dimensional conformance report, and Declaration of Conformity. Additional documentation (Form A/E, fumigation cert, CE/UKCA package) available on request.
Can I get a sample before placing a bulk order?
Yes. Standard model samples can be shipped for evaluation. Freight cost is borne by the buyer (FedEx/DHL). The sample cost is refunded against your first production order.
What is the warranty on Dengtai ladders?
5-year manufacturing defect warranty. Corrosion warranty by material: HDG 2 years, SS304 5 years, SS316 10 years. After-sales: 48-hour response to any issue. If a dimensional error is our fault, we bear the full replacement cost including freight.
How do I start the ordering process?
Send your specification to sales@dtsteelladder.com including: ladder type, height, material, quantity, destination port, and applicable standard. Receive a detailed quotation within 24 hours.
The Dengtai Procurement Process
When you source steel ladders from Dengtai, the process follows six clear stages:
Stage 1: Inquiry and Specification — Send your requirements (ladder type, height, material, quantity, destination port, applicable standard) to sales@dtsteelladder.com. Our engineering team reviews your specification and returns a line-item quotation within 24 hours.
Stage 2: Engineering Review — Senior Engineer Jouth Zhao reviews technical feasibility. For standard products, we confirm the specification. For custom products, we return CAD drawings for your approval. This stage typically takes 1-3 business days.
Stage 3: Order Confirmation — 30% T/T deposit confirms your order. For orders over $10,000, L/C at sight is available. Production scheduling begins immediately upon deposit receipt.
Stage 4: Production and QC — Standard models: 15-20 working days. Custom/bulk: 30-45 working days. Our five-step QC process runs throughout: (1) raw material certification verification, (2) ISO 5817 weld inspection at each joint, (3) coating thickness measurement per ISO 2808, (4) pre-assembly fit check with bracket matching, (5) VCI + vacuum-sealed packaging inspection.
Stage 5: Pre-Shipment Review — Before shipment, you receive: QC documentation package (material certs, weld reports, coating reports, dimensional conformance), container loading photographs, and the container seal number. Review and approve before we release the shipment.
Stage 6: Shipment and Delivery — Container loaded at Tianjin port. Shipping documents sent via courier. Customs clearance support documentation provided. After-sales: 48-hour response to any question or issue.

How to Get the Best Value from Dengtai
1. Provide complete specifications upfront — A complete initial inquiry (ladder type, height, material, quantity, destination, standard) produces the fastest, most accurate quotation.
2. Order in container-friendly quantities — For standard 6m caged ladders, a 40ft container holds 55-70 units. Freight per unit in a full container is $40-70; LCL is $150-300+.
3. Combine multiple ladder types — A mixed order of fixed ladders, caged ladders, and platforms optimized for container utilization saves freight.
4. Standardize where possible — Every custom dimension increases cost and lead time. Check whether a standard height can meet the requirement.
