Product Description

Seeking for a solution to your construction employee's official request? How about considering modular house?

For any construction enterprise, it is a common thing to deploy installation workers to local sites. The worker's safety and well-being must come first, providing satisfied accommodation, catering, and leisure options. Modular houses are a reliable choice due to high mobility and easy assembly.

Modular House System Definition

Modular House is a term used to describe factory-produced pre-engineered building units delivered to the site in modules. These units may form complete rooms or parts of rooms. They are generally made into six-sided boxes, delivered to the site, and set onto foundations using a crane. Modules can be placed side-by-side, end-to-end, or stacked in various configurations.

General Specifications

The modular unit or container is designed as a light solid construction consisting of floor and roof frames and corner profiles. The system enables compounding in longitudinal and transverse directions without limits, up to 2 floors in height (ground + 1) or 3 floors for warehousing.

Manufacturing Process

The manufacturing process involves high-precision steps: Steel plate cutting → H section assembly → Automatic welding → Strengthening → Manual welding → Shot blasting → Painting → Storage.

🛠️ Quality Control Standards

To ensure welding quality, appropriate groove forms are chosen based on metal thickness and welding method. Factors considered include minimizing filler metal, ease of beveling, and reducing after-welding stress.

Frequently Asked Questions (FAQ)

Q1: What exactly is a modular house system? A: It is a construction system using factory-produced, pre-engineered units delivered as modules. These can form entire rooms and are stacked or joined on-site to create complete buildings.

Q2: How many floors can be stacked with these modules? A: The system supports compounding containers up to 2 floors in height for living spaces and up to 3 floors for warehousing purposes.

Q3: What are the insulation materials used in the walls and floor? A: We primarily use noncombustible mineral wool with varying densities (50 Kg/m³ to 120 Kg/m³), ensuring excellent thermal resistance and fire safety.

Q4: Are these modular units certified for international shipping? A: Yes, dimensions, weight, and payload are RINA certified, and the units are designed to comply with ISO Standard 1161 for ease of transport.

Q5: What foundation is required for installation? A: Modular houses can be mounted on flat solid surfaces like asphalt or concrete, point foundations (concrete cubes), or band foundations along the circumference.

Q6: Can the electrical system be customized for different regions? A: The standard layout follows UK Specifications (220V, 50Hz), but the internal distribution system and fittings can be adapted to various voltage and socket requirements.
