Detail Information
1.Roof material:We use blue or white gray color steel sheet with thickness at 0.45mm~0.8mm.
Special color:Red,brown and other color are optional upon customers’ request.
The form of layer structure adopts field composite and factory precast, and the field composite exposed purlin and non-exposed purlin. Glass fiber wool and rock wool sandwiched in the middle;
   

2.Unit weight of fiberglass cotton: 10kg/m3 12kg/m3 14kg/m3 16kg/m3
Advantage:Flame retardant, no open fire, only smoke.
The unit weight of rock wool is big. The outer wall we generally use 140~150kg/m3, and the inner wall (including marble filler, etc.) is 80~120kg/ m3. The layer (with compression resistance) is 180kg/m3.The heat preservation effect of 120kg/m3 is the best.
Fixed color sheet is hidden type and lap joint, and other optional types.The nail we use is self-drilling hexagonal rear-end nail (M5).
Roof lighting system design,:Lighting system has clear and mutual invisible sandwich, and so on.
Day-lighting material glass and transparent polyurethane day-lighting belt.
Roof secondary steel structure is C purlin and square steel, there are also steel and wood structure.
Roof drainage system:also known as organizational drainage.Gutter is made of steel sheet,color sheet,white steel sheet etc.The downpipe shall be PVC or steel plastic spraying pipe (round pipe and square pipe).
C purlins are divided into black and galvanized, black secondary processing, hot galvanization and cold galvanization.Usually we use hot dip.Its corrosion resistance is better and it’s working life can be more than 10 years, cold ones only can be used for one year. Zinc content of the steel plate will be not less than 25 mg / ㎡ to 120 mg / ㎡.
     

3.Interior decoration: color board or bamboo fiber board, gypsum board and other materials.
Color plate heat insulation effect is not too good, but construction is convenient, fast, and low cost.
Compared with color board,the Bamboo fiber board is better in heat insulation, fire retardant, while cost a little higher.
Color board, gypsum board are better in heat insulation than the other two kinds but not very well in waterproof performance.Its cost will be slightly higher. 
Advantages: It can be brushed and paint, easy to open holes and install modeling;If indoor space is big, also can hang marble,but the weight of house will be big.


4.When will we use the crane?
In the plant,the common use crane are single bridge and double bridge.They'll be used in manufacturing processing , riveting and equipment producing.
The tonnage and span of the crane affect the overall quotation of the plant. The reasonable and economic span is 18 meters to 24 meters. The double bridge has good stability but high cost.
Single bridge cost lower.Design size of the crane will be customized according to customers’ request.
