All-close panels produced with German Technology and Machines, adhesive structure with the type of building block, Freon-free polyurethane vesicant material is our innovation,which are very different from traditional open sandwich panel with connect by metals, injected polyurethane at site with Freon.Our surfaces of panels are FRP, the middle with PU foam sheet, The Both surface FRP is connected by FRP stiffener to the whole, During producing, the E-glass fiber, UPR(unsaturated polyester ester resins) and fluorine-free PU foam structured together after heating and pressing , which also makes a layer of UV protection, waterproof, anti-aging, Anti-corrosion in the outer side surface of the panels at the same time.

The main characters are as follows:

1. Light in weight:40% lighter than metal body.

2. Better insulation: K value less than 0.3w/sqm*k.

3. High in strength and long life: 5 times longer than metal body.

4. Non-corrosion, non-pollution, anti-brine, acid and soda-resisting.

5. Easy to assembly and repair at site.

It is also very easy to assemble our insulated bodies, because applying polyurethane adhesive to the joint area of the all-closed sandwich panels, which ensures the joint reliability and optimum insulation, forms them. All bodies CKD we provide have included all necessary accessories such as aluminum angles, aluminum corner, sealing glues, screws, side guards, etc. Therefore, you can assemble them by yourself without purchasing any material. Generally, 3-4 workers can assemble 5-6 bodies everyday. Moreover, at the beginning we will assign our engineers to supply you some technical guidance.
