4 Integrate Modular Building Integrate modular building is the result of new technology innovation. Compared with traditional building construction, it can save 50% labor cost, improve 60% project period. Advantage: Thermal Insulation The product is made of polyurethane foam, which provides the module house of good thermal insulation feature. Fire Resistance The sandwich panels with PU in both side, can protect the building safety due to PU fire rated feature. Impact Resistance The PU filter can provide support to the panel, with the impact resistance of finishing materials like MGO,FC sheet, wood, the shock strength is 10 joules.

5 Water and Moisture Proofing PU foam can prevent moisture absorption, water absorption is only 3%, that also protects steels from being corrosion. Sound Insulation PU foam is optimal deadening. The wallboard made of high injection pressure, is of airtight structure to assure peaceful life space. Energy-saving and Environmental More than 90% of material is recyclable to be used again, which won t produce any waste to damage the environment. Duration The product can be customized design. The structure design durable period much exceeds the scope of national law. Modular assemble construction All products are made as modular production, to assure the field construction with fast installation and low labor intensity.

6 Building Principals: Based on Structural System Supported by Exterior Protected Construction and Interior Installation 3 principles Building Design acted as Core Core----- Building Design Design Philosophy Steel Construction Structure Building Building Design Exterior Construction Interior Installation Body Structure House Layout Facades Design Pipeline System Floor System Anti-fire System Lateral Resisting System Design is the soul of building. We have advanced design management system and professional vision design team with international experience. Retrodict design, focus on customer s expectation, to design house layout, facades, interior decoration and installation.

Wallboard Sound Insulation Thermal Insulation Integrated board of Steel structure with Weighting sound insulated 45db 3.9 R insulation layer (75mm PU board, 35kg/m 3 Integrated Structural System Integrated Structural System, adopts small section H-steel or hot-rolling welding H-steel etc such steel structural parts. Such lattice beam column, makes the full structure bear uniform press, which reduces the stress concentration probability, and improves the house duration under earthquake action. Wall Body and Surface Filler System High density, rigid foam PU 2 Outside base wallboard 3 Inside base wallboard 4 lattice beam column structure. As filler of wall body, PU is made of advanced full water base cyclopentane blowing agents, green environment saving. Through Multipoint high pressure foaming technology, PU play its bonding role to integrate both steel frame and in/outside base board together, also reduce the building weight to save cost.
