Minimum Order Quantity (MOQ) — Steel Ladder Orders
Dengtai maintains low MOQs to support both small-scale orders and large project procurement. Standard models start at 1 unit. Custom models start at 5 units (or single prototype with minimum project charge). This page details MOQ by product type and explains when ordering above MOQ reduces your per-unit cost.
MOQ by Product Type
| Product Type | MOQ | Notes |
|---|---|---|
| Standard fixed ladders (FL-HDG-STD, FL-HDG-EXT) | 1 unit | Single ladder orders accepted with no surcharge |
| Standard caged ladders (CL-HDG-STD, CL-HDG-MULTI) | 1 unit | Single caged ladder orders accepted |
| Stainless steel ladders (FL-SS304, FL-SS316, CL-SS304, CL-SS316) | 1 unit | Higher unit cost but no minimum quantity |
| Standard cat ladders (CT-HDG-STD) | 1 unit | BS 4211 models for UK/Commonwealth markets |
| Custom engineered (CS-ENG) | 5 units | Non-standard dimensions, materials, or configurations |
| Prototype / single custom | 1 unit (minimum project charge $300-500 applies) | Covers engineering time, material procurement, and production setup |
| Heavy-duty models (FL-HDG-HD, CL-HDG-HD) | 5 units | Q345B with >=100um HDG |
| Accessories with ladder order | 1 unit | Safety gates, anti-climb shields, lifeline systems |
| Accessories only (no ladder order) | 5 units | Minimum to cover handling and packaging |
| Spare parts | 1 unit | Replacement rungs, brackets, hoops — no minimum |
Why MOQ Matters for Buyers
Low MOQ Benefits
- Test before committing — Order 1-2 ladders to evaluate quality, packaging, and documentation before placing a bulk order for a large project
- Replacement orders — Replace a damaged ladder without over-ordering
- Small facilities — Purchase for a single building, small warehouse, or limited access point
- Sample evaluation — Request a standard ladder as a physical sample for your engineering team to inspect
When to Order Above MOQ
- Price per unit decreases — Above 10 units, volume efficiencies reduce per-unit cost in material procurement, production setup, and packaging
- Shipping cost optimization — At 20+ standard ladders, a 20ft FCL (Full Container Load) becomes cost-effective vs LCL (Less than Container Load). FCL reduces per-unit freight by 40-60% compared to LCL
- Production slot efficiency — Larger orders get dedicated production scheduling, reducing lead time variability
- Consistent quality batch — All ladders produced from the same steel batch, same coating run, same QC inspection — ensures uniformity across the project
Price Breaks (Illustrative Example: FL-HDG-STD)
| Order Quantity | Unit Price (USD/m) | Savings vs MOQ | Notes |
|---|---|---|---|
| 1-4 units | $23.00 | Baseline | Standard MOQ price |
| 5-9 units | $21.50 | -6.5% | Volume production efficiency |
| 10-19 units | $20.00 | -13% | Bulk material procurement |
| 20-49 units | $18.50 | -19.6% | FCL shipping viable |
| 50+ units | Contact for project pricing | — | Dedicated production scheduling |
Prices illustrative. Actual quotation depends on specifications, material costs at time of order, and destination.
Custom Orders Below MOQ
For single-unit custom prototypes or specialized designs, a minimum project charge applies (typically $300-500). This covers:
- Engineering time for design and CAD drawing
- Special material procurement (small-quantity mill orders cost more per kg)
- Production line setup and changeover
This is often more cost-effective than ordering 5 units of a custom design you only need one of. Contact us with your requirement for a case-by-case assessment.

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.
