Overview of Housing Container Types

Housing containers are mainly classified into the following categories, each with distinct characteristics and uses:

I. Classification by Material

1. Aluminum Alloy Containers: Lightweight, aesthetically pleasing, corrosion-resistant, flexible, easy to process, low repair costs, and long service life. However, they are expensive and have poor welding performance.
2. Steel Containers: High strength, sturdy structure, good weldability, water-tightness, and low cost. However, they are heavy and have poor corrosion resistance.
3. Fiberglass Reinforced Plastic Containers: High strength, good rigidity, large internal volume, good thermal insulation, corrosion resistance, chemical resistance, easy to clean, and simple to repair. However, they are heavy, prone to aging, and have reduced strength at bolt holes.

II. Classification by Structure

1. End-post and Side-post Containers: Primarily referring to aluminum alloy containers, the difference lies in whether the side posts (or end posts) are located inside or outside the end walls.
2. Collapsible Containers: The main components (side walls, end walls, and roof) can be easily folded or disassembled and conveniently reassembled for reuse.
3. Thin-shell Containers: All components are combined into a single steel body, lightweight, and can adapt to torsional forces without permanent deformation.

III. Classification by Purpose

1. General-purpose Containers: Also known as dry cargo containers, mainly used for transporting piece goods, accounting for 70-80% of the total number of containers.
2. Refrigerated Containers: Available in external and internal types, with adjustable temperatures ranging from -60℃ to +30℃, suitable for transporting items that require low temperatures.
3. Open-top Containers: Lack a roof but have a foldable top beam supporting a canopy made of canvas, plastic cloth, or coated plastic cloth, suitable for loading goods that are not excessively tall or bulk cargo.
4. Flat-rack Containers: Lack a roof and side walls, primarily used for transporting oversized and over-width cargo, as well as facilitating the loading of livestock and steel products that can be shipped without packaging.
5. Tank Containers: Also known as liquid containers, they consist of a liquid tank fixed within a metal frame, mainly used for transporting liquid cargo such as chemicals.
6. Garment Containers: Equipped with hanging devices inside, used for transporting garments and other items that require hanging.
