Thickness of Iron Sheets in Container Houses

The thickness of iron sheets in container houses varies depending on their purpose and components, commonly ranging from 0.326mm to 0.6mm, with some special structures being thicker.

I. Thickness of Corrugated Sheets (Walls/Roofs)
Corrugated sheets are the primary covering material for container houses, typically pressed from thin steel sheets. According to common market specifications, their minimum thickness is 0.6mm, with materials including black iron (ordinary carbon steel) and galvanized sheets. Galvanized sheets, being more corrosion-resistant, are more suitable for long-term outdoor use. For example, the quick-assembly container walls produced by Shaanxi Huateng Residential Container Company use 50mm-thick clean-faced sandwich panels with an iron sheet thickness of 0.326mm. However, such sandwich panels may contain internal filling materials, and the actual steel sheet thickness may be thinner.

II. Thickness of Columns and Channel Steels
Columns and channel steels form the skeletal structure of container houses, playing a decisive role in overall load-bearing and stability. Column thickness is typically not less than 1mm and requires professional equipment for shaping. Channel steel specifications are mostly 5X10mm, used for welding the main crossbeams around the top and bottom of the container. Some high-end products use thicker materials, such as the requirement for column wall thickness not less than 2.3mm in professionally customized container mobile homes in Beijing, with frames requiring full-weld treatment to meet the load and anti-overturning requirements in the JGJ/T 435-2018 standard.

III. Thickness of Special Components

1. Packing Box Columns: Some products use galvanized special-shaped materials with a thickness of up to 3mm, such as the steel column specifications of 210mm×150mm×2555mm with a 3mm wall thickness in the packing box-type mobile homes produced by Farile Group.
2. Quick-Assembly Container Profiles: Profile thickness may be 2.3mm or 2.5mm, with a width of 20 centimeters, featuring built-in drainage grooves.
3. Ground and Fireproof Layers: The ground base may use 18mm fireproof boards, with the top insulation cotton thickness reaching 18 square meters (likely a typo, actually 18mm), and the waterproof board thickness being 0.4mm.

IV. Factors Influencing Thickness Selection
The selection of iron sheet thickness requires comprehensive consideration of cost, durability, and usage scenarios. For example, temporary buildings may use 0.6mm corrugated sheets to reduce costs, while long-term residential or high-rise combined buildings will choose thicker columns and channel steels to ensure safety. Additionally, corrosion protection treatments (such as galvanizing) can extend the service life of thin steel sheets, indirectly reducing reliance on thickness.
