• Description:
CLIMA prefabricated house is composed of pre-coated steel structure. 50mm thickness color-coated steel PU sandwich boards have been chosen for wall panels which can obtain a high heatl insulation and offer a good environmental comfort.
Wall boards are interchangeable in case doors and windows may be fitted in any perimetric position.
• Configuration:
• Roof plate: double-sided color-coated steel plate with PU foam (Polyurethane) insulation
•Thickness: 20mm
•PU density: 14kg /m3
• Wall panels: Color-coated steel sandwich plate with XPS (Expanded Polystyrene) or PU foam insulation
•Thickness: 50mm
•XPS density: 14 kg /m3
•PU density: 14 kg /m3
•Doors: same as wall panel
• Windows: Aluminum alloy framed window with sliding glass, standard type windows are 800* 1000mm dimensioned, band type windows are 800* 450mm dimensioned,.
• Steel structure: Pillars are bolted with the foundation bolts. The bolts are grouted in concrete footing foundation.
Steel structure columns: 2C -80X40X20X2.0 (C type steel) are two kinds: Corner Column and Frame Column
Steel columns frame will be bolted. The square shape steel ground beam will connect to the pillars to give extra strength to the entire structure against loads under:

The configuration of flat roof prefabricated house is basically the same as that of slope-crest prefabricated house. The difference lies in the its flat roof, which costs less and is common in regions with little rain falls.
