The appearance of container prefab houses is no longer monotonous

Color steel panel prefab houses, when relocated, involve far less material waste than traditional fixed housing: the same materials can be used to build another house elsewhere, and they are typically used as short-term temporary residences. The following outlines the development of movable houses. The earliest movable dwellings were those left by our ancestors—wood frames covered with straw, corn stalks, and plastic sheeting. Such houses were still common two hundred years ago; some vegetable farmers would build them in the fields while tending crops, then dismantle them after harvest and rebuild the next year. The arrival of color steel panel prefab houses thoroughly transformed temporary housing with greater flexibility, easier installation, and stronger durability. Today there are roughly 2,778 companies producing color steel panel prefab houses nationwide, having evolved gradually from the era of cement-board mobile houses. As a new building material, color steel panel is formed by bonding thin sheets with an auto-formed core on a roll-forming press, offering major advantages: it is waterproof, thermally insulating, brightly colored, and reusable. Cores treated with flame retardants provide better fire resistance. Most temporary buildings on construction sites are now color steel panel prefab houses, with a service life of up to 20 years. Later, in the installation process, a house frame would be enclosed and then wrapped with a rain canopy, making it easier to move without material loss. The drawback is inadequate heating—fine for summer use, but this tent-style shelter is unsuitable in cold winters. In the past two years, container-based container prefab houses have also appeared. Early container prefab houses were converted by welding and installing doors, windows, air conditioning, and similar fittings during the build-out. There are now also units made with color steel panels to match the look of a container.
