construct The veneer core:
　 self-die polystyrene, glass fabric cotton, and rock-cotton. It is a kind of new type building material. The surface is heat-zinc color plating (double) and high tense adhesion agent. The steel board is a kind of new type building or decoration material. The form of the sandwich steel board: first the heat-zinc color steel board's surface layer (double) and the high-intension connected glue through raising temperature and pressure-compound of high-speed continual automobile make-up machine, then through trimming the side, notching, and falling material, finally the steel board is formed.

Specification：
width:1200mm
Breadth: 50,75,1000,150,200,250mm
Length: make the size according to the engine's requirements and the carrying conditions
Color: picking up according to the engine's requirements. Varieties: H steel board (flat steel board, die-mould), matchboard.

Performance:
1. Self-weight: 10.0~13.6kg/m2
2. Heat condition coefficient:0.57~0.114kcal/m2h℃
3. Mechanical intensity (refer to the parameter chart)
4. Limited temperature: -50℃~+120℃
5. Oxygen index (OI): 34.0 (the station of provincial fire protection product quality testing)

The fix is quick and convenient:
　　The width of the steel board is length, which can reduce more than 60% joists; several workers needed to fix the steel board, which can save over one time work-dates

The model is beautiful:
　　The room of the building, which is combined with the color steel board, is clean. The outside of the building is majesty and pageantry; the color is abundant. Various types color compound steel board made the buildings become new scenery.

The building-price is low:
　　The load ability is strong and the span is big. The color steel board's node span is 3.0X3.0m, which compares with the structure of the common span of 1.5~3.0 that is needed two joists, can save the cost about 2/3.
