Duanzhou Build Container House

When building container houses in Duanzhou, it is necessary to comprehensively consider factors such as product type, manufacturer qualifications, safety performance, and cost-effectiveness. The specific key points are as follows:

I. Selection of Container House Types Container houses can be divided into three categories according to their functions:

1. Packing-box Container Houses: These use hot-dip galvanized cold-formed steel frames paired with fire-resistant polyurethane sandwich panels, offering thermal insulation and fire resistance. They are suitable for scenarios such as construction site dormitories and office areas. Their advantages include the ability to be used independently or stacked in multiple layers, and modular design supports rapid assembly and disassembly.
2. Light Steel Keel Houses: These use cold-formed thin-walled light steel keels for load-bearing, with walls filled with insulation materials such as rock wool. The appearance and layout can be customized, making them suitable for long-term use scenarios such as cultural tourism homestays and scenic area facilities.
3. Functional Supporting Houses: Such as security guard posts and eco-friendly public toilets, with flexible adjustment of size and layout to meet specific scenario requirements.

II. Manufacturer Qualifications and Production Capacity

1. Qualification Verification: Prioritize manufacturers with qualifications in steel structure processing and fire-resistant material production, avoiding small workshops without self-developed production capacity. For example, Shandong Xinhao Integrated Housing Co., Ltd. provides standardized and modular production, with products verified through large-scale projects by China Railway and China Construction.
2. Production Process: Regular manufacturers use standardized production lines to complete processes such as steel structure welding, wall panel composite processing, and pre-embedding of water and electricity pipelines. Trial assembly before leaving the factory ensures component compatibility. For example, Shengshan Integrated provides full-chain services including production, transportation, and assembly, shortening construction periods and strictly controlling costs.

III. Safety Performance and Material Standards

1. Fire Protection Requirements: Filling materials must meet Class A fire protection standards, such as rock wool boards and fire-resistant cotton, avoiding the use of flammable materials like polystyrene and polyurethane foam.
2. Structural Stability: The frame uses hot-dip galvanized cold-formed steel, offering excellent rust and corrosion resistance; wall panels use rock wool and glass wool sandwich panels, providing both sound insulation and fire protection functions.
3. Electrical Safety: Wires and cables are equipped with protective sleeves, sockets and switch boxes use metal galvanized boxes and are surface-mounted, and simple fire-fighting equipment is provided.

IV. Cost-Effectiveness and Long-Term Use

1. Full Life Cycle Cost: Modular container houses can be repeatedly assembled, disassembled, and relocated, significantly reducing construction waste and pollution, with overall costs lower than traditional prefabricated temporary buildings. For example, the modular houses built by China Construction Integrated Architecture for an Australian project reduced the construction period by more than half.
2. Service Life: High-quality products can have a lifespan of up to 30 years and support recycling, aligning with low-carbon and environmentally friendly trends.
