Materials for Container Houses (Feug)
Container houses are primarily made of materials such as steel, sandwich panels, and fiberglass-reinforced plastic (FRP). The specific materials and their characteristics are as follows:
Steel is the core structural material for container houses, mainly used for the main frame and support structures. Typically, galvanized steel or weathering steel is selected, with a thickness of 1.2-2mm, connected by welding or bolts, conforming to ISO standards. Weathering steel forms a dense, dark brown oxide layer on its surface by adding trace amounts of alloying elements such as phosphorus, copper, chromium, and nickel, effectively preventing internal metal corrosion. It is particularly suitable for environments with high humidity and salt content, such as those along rivers and coasts, significantly extending its service life compared to ordinary steel.
Sandwich panels serve as the enclosure material for container houses, composed of inner and outer layers of color-coated steel plates with an intermediate filling layer. The filling material determines its performance: polyurethane has a fire rating of B1, while rock wool can reach A-grade, offering both thermal insulation, sound insulation, and fire resistance. For example, rock wool sandwich panels do not burn at high temperatures, effectively delaying the spread of fire, while polyurethane is characterized by its lightweight and efficient thermal insulation.
Flooring materials need to balance strength and durability. Common choices include 18mm-thick multi-layer plywood or checkered steel plates, with anti-rust treatment on the surface. Some high-end container houses use high-strength bamboo-wood composite flooring over 28mm thick, combining the elasticity of wood with the compressive strength of bamboo, capable of withstanding the碾压 (crushing) of several tons of forklifts, suitable for industrial or warehousing scenarios.
Door and window materials focus on airtightness and energy efficiency. Frames are mostly made of plastic-steel or thermal-break aluminum, paired with double-glazed units, effectively isolating noise and heat transfer. For example, thermal-break aluminum blocks heat conduction through internal thermal insulation strips, improving overall thermal insulation performance.
Among other materials, fiberglass-reinforced plastic (FRP) or aluminum alloy are used in high-end container houses to reduce weight and enhance corrosion resistance. Auxiliary materials include rock wool or polyurethane foam for filling sandwich panels, and ethylene propylene diene monomer (EPDM) rubber seals for box joints, which can withstand temperature changes without cracking or aging. The exterior coating often uses high-weather-resistant polyester powder, offering outstanding resistance to ultraviolet rays and corrosion, extending the service life of the house.
These materials, when scientifically combined, endow container houses with characteristics such as structural stability, diverse functionality, and strong adaptability, making them widely applicable in temporary buildings, mobile offices, residential renovations, and other fields.
