Packaging Container Houses, also known as modular container houses or shipping container houses, are constructed with steel frame structures and cold-bent galvanized steel. The structure is composed of top frame components, corner column systems, and bottom frame components. All system modules are manufactured in the factory and assembled on-site. They are a type of modular building that can be easily moved and reused, representing an upgraded generation of temporary buildings in the temporary construction industry. They are widely used for offices, dormitories, meeting rooms, bathrooms, kitchens, access control, and more. With diverse application fields, they can be used for construction sites, commercial housing, public utility buildings, camps, tourism, municipal temporary housing, disaster relief housing, temporary isolation rooms, and more. There are no special requirements for the site of packaging container houses. If not used in combination, the placement of the container houses does not require foundation work; even on muddy ground, they can be placed, connected to an external power source, and used immediately without any on-site installation or wiring needed. They have a lifespan of at least 20 years, can be reused and moved repeatedly, and do not require disassembly or material loss. They are environmentally friendly, save labor, and are versatile. Packaging container houses are sturdy and durable, entirely made of steel, with strong seismic and deformation resistance, good sealing performance, and excellent water-tightness due to strict manufacturing processes. They are easy to disassemble and assemble, have superior performance, stability, and vibration resistance, are waterproof, fireproof, and corrosion-resistant, lightweight, and the houses are of an integrated structure with an internal frame and steel walls that can be clad with wood panels. They are easy to migrate as a whole, and their lifespan can reach over 20 years.
