Container House Accessories
The main accessories for container houses include steel structural frames, enclosure panels, floors, corner fittings, connectors, and various auxiliary accessories. The following provides an introduction based on different accessory types:
Steel structural frames are the core supporting structures of container houses, typically made of C-shaped steel or square steel. The strength of the frame directly affects the load-bearing capacity and service life of the house. For example, to meet the requirements of multi-story combinations, some suppliers increase the thickness of the column steel from 4 millimeters to 6 millimeters and add reinforcing ribs at connection nodes, improving the overall compressive strength by approximately 50%.
Enclosure panels include roof panels, side panels, and front panels, often designed with corrugated or ribbed sheets. In terms of materials, common options are galvanized steel sheets, color-coated steel sheets, or weather-resistant steel sheets, with some products incorporating rock wool sandwich layers to enhance thermal insulation. For instance, in areas with long winters like Jining, suppliers use a combination of 100-millimeter rock wool sandwich panels and 0.8-millimeter corrugated steel sheets to meet insulation requirements at -30 degrees Celsius and reduce the risk of condensation by adjusting the coating formula (e.g., using high weather-resistant polyester resin on the outer layer and moisture-proof aluminum foil on the inner layer).
Floor materials are primarily wooden plywood, with some products undergoing waterproof treatment or having an additional load-bearing layer. For example, the floors used in container repair and construction often combine weather-resistant steel rear sills with wooden plywood, ensuring structural strength while controlling costs.
Corner fittings and connectors are crucial for the modular assembly of container houses. Standard corner fittings must comply with the GB1835-2006 specification and are used for vertical and horizontal connections between containers. Additionally, accessories such as positioning rings, locking rings, and hole lock seats enable rapid assembly, with some products featuring quick-connect designs that embed water and electrical lines within the container chassis to reduce on-site construction errors.
Auxiliary accessories include seals, hinges, wind hooks, and lashing rings. For example, ethylene propylene diene monomer (EPDM) rubber seals offer better weather resistance than ordinary silicone seals, with a service life of over 5 years; the bending angle of door frames must be controlled within plus or minus 0.5 degrees, and when combined with a uniform and continuous glue application process, this effectively improves the airtightness of the container, making it suitable for sandy and dusty weather conditions.
Regarding special-requirement accessories, for mobile houses, suppliers offer expandable shells, side-opening structures, or lightweight frames; for multi-story buildings, thicker frame materials and reinforced connection nodes are required to ensure structural stability.
