40′ Double Door Container

Description

40′ Double Door Container for Sale – A Versatile, High-Cube Storage and Modification Solution

A 40′ double door container for sale is a highly versatile unit featuring full cargo doors on both ends, providing exceptional access, improved workflow, and easier loading/unloading compared to standard single-door containers. Built from heavy-duty CORTEN steel and equipped with marine-grade plywood flooring, these units offer outstanding strength, weather resistance, and long-term durability. Double door containers are typically sold in high cube (9’6”) height, giving you additional vertical clearance for larger equipment, tall pallets, or spacious modification projects.

These containers generally arrive in near-new (one trip) condition, showing only minimal cosmetic marks from transport. Both door sets are fully functional and equipped with secure locking bars, thick rubber door gaskets, and anti-corrosion protective coatings. Each end can be opened independently, making them ideal for applications that require flexible access, partitioning, or drive-through loading.

Whether used for storage, workshops, workflow-optimized warehousing, equipment access from both ends, or advanced modifications, a 40′ double door container from Seablox delivers top-tier usability, increased accessibility, and excellent long-term value.

Required Clearances for 40′ Double Door Container Delivery (Tilt-Load Truck)

1. Length Clearance

• 80–100 ft (24–30 m) needed
  Truck + tilt angle requires roughly double the container length.

2. Height Clearance

• 14–16 ft (4.3–4.9 m)
  Essential due to the steep tilt angle during unloading.

3. Width Clearance

• Minimum 12 ft (3.7 m)
  More space is preferred for precise placement.

4. Ground Conditions

• Firm, level ground required

• Avoid mud, soft soil, or slopes

• Gravel or pavement recommended

5. Turning Radius

• 50–60 ft (15–18 m) if maneuvering is required

Proper clearances prevent delays, unsafe drops, and extra handling charges.
