K-type Prefab House Basic Introduction
I. Core Structure
Frame System
Utilizes a light steel structure (K-shaped steel or C80# steel) as the main framework, enabling modular assembly via standardized modules (e.g., 1820mm or 2000mm). Components are bolted for rapid installation and disassembly.
Single-story clear height: up to 2760mm; adjustable for double- or triple-layer designs (e.g., 2560mm per layer for double-story).
Enclosure System
Walls: 50mm-thick double-sided color steel sandwich panels.
Roof: 20mm-thick PU tiles or color steel sheets, offering waterproofing, insulation, and thermal retention.
Flexible placement of doors/windows; external staircases to save indoor space.
II. Primary Applications
Construction Sites: Temporary dormitories, offices, warehouses, and command centers.
Public Facilities: Emergency shelters, mobile hospitals, schools, and exhibition halls.
Commercial Use: Pop-up stores, outdoor camps, and mobile showrooms.
III. Key Performance Features
Load-Bearing & Seismic Resistance
Floor live load: 150 kg/sqm; seismic resistance up to Grade 7, complying with safety standards.
Wind Resistance
Sloped roof design with reinforcement withstands Grade 10 winds, outperforming flat-roof prefab houses.
Installation Efficiency
A 4-person team can install 80-100 sqm/day; reusable for over 10 cycles with minimal wear.
Eco-Friendly & Cost-Effective
Recyclable materials; annual operating costs lower than traditional temporary structures.
New units: ~220 RMB/sqm; second-hand market: 30-50 RMB/sqm.
IV. Advantages
Flexible Layout: Adjustable partitions, doors, and windows; expandable from single to triple stories.
Durability: Anti-corrosion-treated steel components; lifespan exceeds 10 years.
Aesthetic Appeal: Wall colors (white-gray, beige, camouflage) and roof options (red, blue).
Transport Efficiency: 40-ft container holds 200-300 sqm, suitable for inland logistics.
V. Differences from T-type Prefab Houses
K-type: K-shaped steel frame for superior wind/seismic resistance; ideal for harsh outdoor environments.
T-type: T-shaped steel frames prioritize mobility; better suited for long-term commercial/residential use.
