Galvanized Columns for Container Houses

The common specifications, characteristics, and purchasing considerations for galvanized columns in container houses are as follows:

Common Specifications and Thickness

The steel thickness of galvanized columns for container houses varies depending on their intended use and design requirements. Among common specifications, ordinary suppliers may use 4mm thick square steel, but there is a risk of deformation in the bottom columns due to excessive local pressure when stacked in two layers. Suppliers that have undergone transformation typically use 6mm thick square steel and add reinforcing ribs at connection nodes, increasing overall compressive strength by approximately 50%. Additionally, some products use 3mm thick galvanized columns, such as the packaged modular temporary buildings from Far East Leasing Group, which have steel columns with dimensions of 210mm150mm2555mm and a thickness of 3mm. When purchasing, it is also important to note the wall thickness of the columns, with common specifications ranging from 1.5mm to 3mm. Thicker walls provide greater load-bearing capacity but also increase the self-weight.

Galvanizing Process and Corrosion Resistance

The galvanizing process is crucial for the corrosion resistance of container house columns. Hot-dip galvanizing offers a longer corrosion-resistant lifespan than cold galvanizing, especially in areas with significant temperature variations between day and night and humidity changes, where the quality of the coating directly determines the rate of rusting on the container body. Therefore, when purchasing, priority should be given to columns that have undergone hot-dip galvanizing to ensure long-term stability and safety.

Structural Design and Load-Bearing Capacity

The columns of container houses serve as the skeleton of the entire structure, providing support and playing a decisive role in the sturdiness of the house. When purchasing, in addition to considering the thickness and galvanizing process of the columns, attention should also be paid to their structural design. For example, details such as the steel thickness of the main beams and columns, and whether the welding process is full and free of cold welds, determine the safety of the container house during lifting, stacking, and transportation. Additionally, some products enhance overall compressive strength by adding reinforcing ribs to meet higher load-bearing requirements.
