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.
Raw Material Cost Breakdown
Understanding the cost structure of a steel ladder helps buyers evaluate whether a quotation is reasonable and where value engineering opportunities exist.
Material Cost Per Tonne (2026 Indicative)
| Material | Raw Material | Fab Cost | Labor | Surface Treatment | Total/tonne |
|---|---|---|---|---|---|
| Q235B HDG | $692 | $180 | $210 | Included in fab | $1,082 |
| Q345B HDG | ~$750 | $200 | $230 | Included in fab | ~$1,180 |
| SS304 | $2,538 | $400 | $480 | Passivation ~$150 | ~$3,568 |
| SS316 | $4,615 | $600 | $850 | Passivation ~$200 | ~$6,265 |
A standard 6m caged ladder (CL-HDG-STD) weighs approximately 80-100 kg depending on configuration. At Q235B HDG total cost of ~$1,082/tonne, the material cost is approximately $87-108. The remaining cost in the $180 retail price covers direct labor, factory overhead, packaging, compliance documentation, and margin.
Pricing Formula for Custom Orders
For large-volume or custom orders (>100m total length), Dengtai uses the formula:
Price = Material Cost + Sheet Metal Processing + Labor + Surface Treatment + 15% Margin
This transparent pricing methodology allows buyers to understand what drives cost and identify opportunities for value engineering:
- Wider rung spacing (300mm standard): No cost change — standard spacing is already optimized
- Non-standard width: Proportional material increase
- Different material grade: Cost changes per the raw material differential above
- Additional surface treatment (duplex coating, special paint): Incremental cost quoted separately
- Volume discount: Applied progressively based on total project quantity

Lead Time Management and Optimization
Factors That Extend Lead Time
| Factor | Impact | Mitigation |
|---|---|---|
| Custom engineering | +15-25 working days | Provide complete specifications upfront; approve drawings promptly |
| Non-standard material procurement | +7-15 working days | Use in-stock materials where possible (Q235B, Q345B, SS304, SS316 are standard stock) |
| High order volume (>500m) | +10-20 working days | Split production lots if partial delivery is acceptable |
| Peak season (Aug-Oct) | +5-10 working days | Order in Q1-Q2 for Q4 delivery |
| Third-party inspection scheduling | +3-7 working days | Book the inspector when production starts, not when complete |
| Classification society involvement | +10-20 working days | Engage the surveyor at the drawing approval stage |
Lead Time by Product Category
| Product Category | Standard Lead Time | Notes |
|---|---|---|
| Standard fixed ladder (FL series) | 15 working days | 1-50 units; for >50 add 5 days per additional 50 |
| Standard caged ladder (CL series) | 15-20 working days | Cage fabrication adds 0-5 days |
| Multi-section caged ladder | 20-25 working days | Platform fabrication and pre-assembly check add time |
| Custom ladder (CS-ENG) | 30-45 working days | Includes engineering, drawing approval, custom fabrication |
| Accessories only (brackets, hoops) | 10-15 working days | Shorter if combined with ladder order |
| Spare parts | 5-7 working days | In-stock parts ship immediately |
Rush orders: For time-critical projects, we can evaluate rush production. Rush orders typically add 15-25% to the product cost and reduce lead time by 5-10 working days for standard products. Rush production is subject to current production schedule availability.

FAQ
Q: Why T/T 30/70 instead of 100% upfront?
The 30% deposit confirms your order and covers raw material procurement. The 70% balance before shipment ensures the order is complete and QC-approved before you make full payment. This is standard practice in Chinese industrial manufacturing export.
Q: Is L/C (Letter of Credit) available?
Yes, L/C at sight is available for orders over $10,000. The L/C must be issued by a reputable international bank and be irrevocable. L/C terms must be confirmed before order acceptance.
Q: Can I pay after receiving the goods?
D/A (documents against acceptance) and open account terms are not available for first-time buyers. After establishing a purchase history, alternative payment terms may be considered on a case-by-case basis.
