1. Product Overview: A Heavy-Duty Logistics Solution Purpose-Built for Height-Restricted Scenarios

The 20ft low-height container is a specially designed standard container tailored for height‑restricted routes, low‑clearance warehousing, and special transport conditions. While retaining the universal compatibility of a standard 20ft container, it breaks through traditional height limitations with an ultra‑low external height of 2,438mm and combines it with an 28,420kg extra‑large payload, perfectly solving the industry challenge of "height‑restricted but heavy‑load required transport". It is the ideal choice for bridge/culvert transport, low‑clearance factory storage, and heavy equipment export.

Core Advantages:

• Low height without sacrificing strength – payload far exceeding conventional 20ft containers; tare weight of only 2,060kg; lightweight design achieves higher loading efficiency.

• Scenario advantage – fits transport routes with height restrictions under 2.5 metres, eliminating the need for special permits or detours, significantly reducing transport costs and time.

• Universal compatibility – ISO‑compliant dimensions allow direct interfacing with global standard container spreaders, trailers and yard equipment without modification.

2. Product Features & Applications: Low Height, High Capacity – Full Scenario Coverage

✨ Key Features

• Ultra‑low height – easily handles height‑restricted scenarios – external height of only 2,438mm, suitable for the vast majority of roads, culverts and tunnels with height limits under 2.5 metres – eliminating "over‑height" concerns.

• Super‑heavy payload – maximised transport efficiency – maximum gross weight 30,480kg, maximum payload up to 28,420kg – far exceeding the load capacity of ordinary 20ft containers; more cargo per container, lowering per‑unit transport costs.

• Standard universal design – adaptable to all logistics scenarios – length and width identical to conventional 20ft containers; directly compatible with standard spreaders, trailers and yard equipment; suitable for sea, road and rail intermodal transport.

• Robust and durable – full safety protection – high‑strength corrugated steel body + fully welded structure; allowable stacking weight of 192,000kg ensures multi‑layer stacking without deformation; excellent water, dust and corrosion resistance.

🛠️ Typical Applications

• Height‑restricted road transport – heavy cargo such as steel, building materials and chemical raw materials requiring passage through low culverts, bridges and tunnels; the low‑height design eliminates detours.

• Low‑clearance factory / warehousing storage – for facilities with insufficient ceiling height; can be used directly as storage containers without building modifications, flexibly storing equipment, spare parts and raw materials.

• Heavy equipment export – heavy machinery, machine tools, metal components; the ultra‑high payload allows full loading in a single shipment, reducing transport batches.

• Special condition logistics – materials for mining and tunnel projects; temporary offices and tool storage in low‑clearance sites, adapting to complex operational requirements.

4. Production Equipment, Quality Certifications & Customer Cases

🏭 Production Equipment & Processes
We use an industry‑leading automated special‑container production line – from steel plate pre‑treatment, CNC cutting, box welding to full‑body sandblasting and coating – with end‑to‑end MES system control. Key welds undergo 100% ultrasonic flaw detection, and each unit is factory‑tested with rigorous stacking tests, lifting tests and watertightness tests, ensuring box strength and sealing meet international standards.

📜 Authoritative Quality Certifications
The product is ISO 9001 certified, holds China Classification Society (CCS) approval, and we can provide the CSC (International Convention for Safe Containers) certificate, meeting global shipping export standards for direct use in international logistics without additional testing.

📦 Customer Case Studies
