A1 Class Fireproof Prefab Container Office China manufacturer factory supplier quality, Ante House provides modular office buildings with insulated sandwich panels, galvanized steel frame, fast installation and customized layouts. The product supports multi-layer design, energy saving performance and long service life for project offices.

Efficient Modular Space Solution

A1 Class Fireproof Prefab Container Office is designed for fast deployment, flexible layout planning, and long-term stable use in different working environments. The structure combines cold galvanized steel frame systems with insulated sandwich wall panels to provide reliable performance for temporary and permanent office applications.

The product supports customized room arrangement and can be used as a single office unit or connected into larger office complexes. Multi-layer configurations are also available according to project requirements.

Stable Structural Design

The main frame uses cold galvanized steel with multiple thickness options including 2.2mm, 2.5mm, 3.0mm, and 4.0mm. The reinforced structure improves overall stability during transportation, installation, and long-term use.

The top and bottom frame use precision-processed steel plates. Structural connection parts with 8.0mm thickness help improve connection strength between columns and frame sections.

Four integrated downspouts are included in the column system to improve rainwater drainage performance and reduce water accumulation.

Reliable Fire Protection Performance

A1 Class Fireproof Prefab Container Office adopts fire-resistant wall systems designed to improve safety in industrial zones, project camps, temporary offices, and construction sites.

The wall panels are available in 50mm, 75mm, and 100mm thickness options. Glass wool insulation materials provide stable thermal insulation and improved fire resistance performance.

The insulated wall structure helps reduce heat transfer while maintaining interior comfort under different climate conditions.

Practical Interior Space

The standard unit external size is 5810mm × 2330mm × 2540mm, while the internal usable space is 5650mm × 2170mm × 2160mm.

The interior layout can be adjusted according to application requirements. Independent office rooms, meeting rooms, staff rooms, reception areas, and management spaces can all be integrated into the design.

Optional interior systems include:

- Power supply system
- Water supply system
- Drainage system
- Distribution box
- Lighting system
- Socket configuration
- Wash basin
- Toilet system
- Shower facilities
- Washroom cabinet

Window and Door Configuration

The standard steel door size is 950mm × 1970mm. Window systems use PVC frame glass windows with 5+9+5 double-layer glass structure.

The window size is 1150mm × 1150mm and can also be customized according to ventilation and lighting requirements.

The double-layer glass design helps improve sound insulation and thermal performance while maintaining interior brightness.

Floor System

The floor adopts 18mm cement board for stable support and long-term durability.

Additional floor finish options include:

- Leather floor
- Floor tile
- Wood floor

The standard leather floor thickness is 2.0mm. Different floor materials can be selected according to project environment and maintenance requirements.

Fast Installation Process

The product is developed for efficient assembly and transportation. The packing size is optimized to reduce shipping volume and improve loading efficiency.

20GP containers can load 6 units, while 40HQ containers can load 12 units.

The modular structure allows quick installation with simplified connection methods. Four workers can complete installation of one unit within approximately one hour under normal conditions.

Detailed installation drawings and video guidance are available for project support.

Climate Adaptability

The product can be adjusted for different environmental conditions.

For strong wind regions, the internal structure can be reinforced to improve wind resistance performance.

For cold climate areas, thicker insulation walls and higher thermal performance materials can be selected.

For high corrosion environments, anti-corrosion coating systems and corrosion-resistant materials are available.

Energy Saving Design

A1 Class Fireproof Prefab Container Office uses energy-saving wall panels and modular manufacturing technology to reduce material waste during production and installation.

The modular design also supports repeated use and relocation, helping improve long-term utilization efficiency.

The product can be dismantled, transported, and reinstalled multiple times while maintaining structural integrity.

Application Scenarios

This product is suitable for:

- Construction site office
- Temporary project office
- Mining camp office
- Industrial management room
- Engineering command center
- Commercial modular office
- Staff administration building
- Remote area office space

The modular system allows flexible expansion according to changing project requirements.

Production and Quality Inspection

Every production stage follows strict inspection procedures including raw material inspection, frame processing inspection, welding inspection, and final assembly inspection.

The factory uses complete prefab house production lines including steel sheet press machines, welding lines, baking paint systems, and sandwich panel production equipment.

The manufacturing process helps maintain product consistency and stable quality control.

Long Service Life

Under standard climate and environmental conditions, the steel structure service life can reach 30 years.

The galvanized steel frame and protective coating system help improve durability and reduce maintenance frequency during long-term use.

Technical Support Service

Technical support includes:

- CAD drawing support
- 3D layout design
- Installation guidance
- Technical consultancy
- After-sales support

For large projects, on-site installation support and supervision can also be arranged according to project conditions.

Flexible Appearance Customization

Standard wall and frame colors use white coating, while additional colors can be customized according to project style requirements.

The modular appearance design allows the product to integrate into industrial, commercial, and temporary office environments.

A1 Class Fireproof Prefab Container Office combines fast installation, modular flexibility, insulated wall systems, and stable steel structure performance for modern workspace projects.
