Prefabricated Finished Color Steel House

A prefabricated finished color steel house is an environmentally friendly and cost-effective building that uses light steel as its framework and sandwich panels as its wall materials, combined through bolts or welding. It features the ability to be quickly assembled and disassembled, as well as universal standardization.

I. Structure and Materials The framework of a prefabricated finished color steel house typically employs light steel H-beams or channel steels, with sandwich panels serving as the wall materials. Sandwich panels are mainly classified into four categories based on their internal core materials:

1. Polyurethane sandwich panels: These offer excellent thermal insulation but have a flammable core material that can produce toxic gases in fires, necessitating strict fire prevention management.
2. Polystyrene (EPS) sandwich panels: These are relatively low-cost but also pose a flammability risk, making them suitable for temporary scenarios with low fire safety requirements.
3. Rock wool sandwich panels: Using rock wool as the core material, these panels have an A-grade non-flammable rating, are heat-resistant, and provide good thermal insulation, often used in places with strict fire safety requirements.
4. Glass wool sandwich panels: These have fire resistance close to that of rock wool but slightly weaker sound insulation and thermal insulation performance, with a relatively lower price.

II. Types and Prices Common types of prefabricated finished color steel houses on the market include:

• Foldable container movable panel houses: These feature a modular design and can be folded for transportation, making them suitable for scenarios requiring frequent relocation. Prices vary significantly depending on specifications, with some products priced at ¥200.56 (possibly for small sizes or accessories).
• On-site temporary dormitory prefabricated assembled houses: These are mainly assembled over large areas to provide temporary living spaces, with prices possibly calculated per square meter, such as ¥7.4/square meter (specific prices depend on materials and configurations).
• Fixed color steel houses: These have a more stable structure and are suitable for long-term use, with higher prices. For example, some products are priced at ¥4800.0 (possibly for complete units or high-configuration models).

III. Construction and Safety During construction, the ground foundation should be compacted and leveled first, followed by concrete pouring and line marking to determine room dimensions. Then, columns should be erected and connected to the framework with transverse beams. Safety precautions:

1. Fire safety requirements: Color steel houses using flammable core materials (such as polyurethane and EPS) should be equipped with fire extinguishing equipment, avoid open flame operations, and maintain clear safety passages.
2. Wind resistance reinforcement: In areas with strong winds, additional ground anchors, diagonal braces, and other structures should be added, or the house height should be reduced to decrease wind resistance.
3. Regular inspections: After long-term use, checks should be conducted for loose bolts, wall deformations, and other issues, with timely repairs made to ensure structural safety.
