Heilongjiang Container House Materials

Container houses in Heilongjiang mainly use steel, sandwich panels, flooring materials, and door and window materials. The specific analysis is as follows:

Steel is the core material for the main frame and supporting structure of container houses in Heilongjiang. The first-floor frame typically uses high-strength steel, such as Q235 or Q345, to ensure structural stability and load-bearing capacity. In Heilongjiang, due to the cold winters and heavy snowfall, it is recommended to choose steel with a thickness of over 3mm to better withstand low temperatures and snowstorms. The steel is generally galvanized steel or weathering steel, with a thickness between 1.2 - 2mm, connected by welding or bolts, and complies with ISO standards. This type of steel not only has high strength but also good corrosion resistance and durability, ensuring long-term use of container houses in harsh environments.

Sandwich panels are commonly used materials for the walls and parts of the roof of container houses. They consist of two layers of color-coated steel sheets with an intermediate filling material, and the choice of the filling material determines the performance of the sandwich panel. Common filling materials include polyurethane, rock wool, or glass wool. Polyurethane has a fire rating of B1, while rock wool has an even higher fire rating of A. In Heilongjiang, due to the cold winters, container houses require good door and window sealing performance, so sandwich panels with insulation layers can be chosen to reduce heating costs. Sandwich panels not only have good thermal insulation and sound insulation properties but also certain fire resistance, meeting the usage requirements of container houses in different environments.

For flooring materials, container houses in Heilongjiang commonly use 18mm-thick multi-layer plywood or checkered steel plates. Multi-layer plywood has good load-bearing capacity and stability, while checkered steel plates are slip-resistant and wear-resistant. The floor surface is usually treated with anti-rust measures to extend its service life.

Door and window materials are selected from plastic-steel or thermal-break aluminum frames, paired with double-glazed units. This type of door and window material not only has good sealing performance but also effectively isolates external noise and cold air, improving the living comfort of container houses.
