Introduction

The base frame of a shipping container is the foundation upon which its structural integrity and load-bearing capacity depend. It is typically constructed using robust steel components and is designed to withstand significant stress, making it crucial for shipping, storage, and repurposing applications.

Materials and Design Considerations

The primary material used in constructing shipping container base frames is COR-TEN steel, known for its corrosion resistance and tensile strength. The frame generally features cross-members and beams that form a rigid, rectangular structure. Typically, steel with a minimum yield strength of 235 MPa is employed. Galvanization is often applied to prevent rusting.

Construction Process

The construction of a shipping container base frame involves several meticulous steps:

  1. Cutting: Steel components are cut to specified dimensions using CNC plasma cutting to ensure precise size and angles.
  2. Welding: The components are welded together using MIG welding techniques to ensure strong joints, particularly at the corners where the structural load is concentrated.
  3. Reinforcement: Additional steel sections, such as cross-members, are welded to distribute loads evenly across the base.
  4. Surface Treatment: A coat of primer and paint is applied to protect against environmental exposure.

Numerical Analysis and Parameters

The standard shipping container base frame is typically designed to possess the following parameters:

  • Length: 20 to 40 feet (approx. 6 to 12 meters)
  • Width: 8 feet (approx. 2.44 meters)
  • Height: 8.5 feet (standard) or 9.5 feet (high cube)
  • Load Capacity: Up to 30,480 kg (67,200 lbs)

Finite Element Analysis (FEA) is often employed to simulate stress distribution and optimize the design for maximum efficiency and safety.
