Efficient Contruction: Sandwich panel provide easy installation which can be triple faster than usual  concrete  building. It can also has less affection from weather during construction. It allows large span, the supporting  structure can be lighter.

Perfect Energy Saving  :  Sandwich panels provides high thermal insulation by means of PUR, PIR, EPS and Mineral Wool insulation materials. It has lower U value and higher insulation capability .

Environmental Friendly:  Sandwich panels require less maintenance than concrete an brick structure; repainting  is not required. It is more economical and environmental friendly.

Safe, Durable and Reusable:  Sandwich panels are light weight that are easy and safe to handle during con- struction. Also can be easy assembly and disassembly.

Versatility:  Sandwich panel can be used for various applications, such as pre-fabricated steel buildings , warehouse, walk-in cold storgaes, cleanroom, farm, food processing plant and etc.

Benefit and Value:  Compare with traditional construction, sandwich panel are more economical in terms of labours,machines,time, maintenance.cost etc. It enables big saving in future operation costs.
