GENERAL INFO
All prefabricated modular type buildings are constructed on the reinforced concrete foundations. After completion of the erection of all external – internal walls, roof and suspended ceiling; leveling concrete (screed) must be prepared to install floor covering materials.
Foundation and leveling works should be prepared by the client.

5. Bracing: Bracing made with thread tapping and hot-dipped galvanizing finishes.
6. Main elements and typical connection details:
WALL AND ROOF PANELExterior Walls : Prefabricated sandwich panel made up from pre-colored galvanized steel plate of 0.5 mm. in thickness at inner/outer face and EPS (R Value 33.30) insulation of 100mm in thickness and 12kg/m3 in density. Wall frame will be constructed of steel profiles.
Interior Walls : Prefabricated sandwich panel made up from pre-colored galvanized steel plate of 0.5 mm. in thickness at inner/outer face and EPS (R Value 33.30) insulation of 75mm in thickness and 12kg/m3 in density. Wall frame will be constructed of steel profiles.
Polystyrene foam sandwiched panel constructed by 2 layers of pre-painted steel plate and high density polystyrene foam jointed by strong adhesive, under high compressed process to form solid panel.
EXTERNAL COATING (Optional Item)
Specification of Texture Coating (Grey stone appearance):
Elastic exterior coating is flexible coating used to help protect and maintain the appearance of exterior masonry walls. It is designed to bridge existing and future cracks in masonry by stretching and shrinking as exterior walls expand and contract with changes in temperature. Use of elastic exterior coating is an excellent way to help prevent wind driven rain, acid rain and freeze-thaw conditions from damaging a building’s appearance and structural integrity.
Application Reference:
a) Surface preparation: Previously unpainted surface clean of dust, grease and loose matter. Remove unstable old film by high pressure wash or scraper. The substrate should be clean, dry and stable, ensure the surface moisture < 10%,PH<9.5.
b) Primer: sealer. Theoretical spreading rate: 6-8m2
.
c) Finish: Stir well before use, brush 1-2 elastic coating. Theoretical spreading rate: 1-1.5m2
(two coats). Interval: ≥6h. The temperature of application environment and substrate should ≥5oC.
CEILING1. For Dry Area: 9.5mm thick gypsum board suspended ceiling of with galvanized concealed grid.
2. For Wet Area: PVC suspended ceiling of 8 mm. in thickness with concealed grid.
