A sandwich Panel is any structure made of three layers: a low-thickness center, and a meagre skin-layer attached to each side. The sandwich panel is utilized in applications where a blend of high basic inflexibility and low weight is required.

　　The sandwich panel is a case of a sandwich-organized composite: the quality and softness of this innovation make it prevalent and across the board. Its adaptability implies that the panel has numerous applications and come in numerous structures: the centre and skin materials can shift generally and the centre might be a honeycomb or a strong filling. The encased panel are named tapes.

　　Metal-faced polyurethane sandwich puff panels are the system of choice of today for large industrial buildings refrigerated warehouses, office blocks, exhibition halls, fair pavilions, schools, and sports halls.

　　The aluminium or steel facings themselves are surface coated and can be manufactured with profiles of various depths leading to a higher load bearing.

　　Polyurethane sandwich puff panel comes complete with specially formed tongue-and-groove joints ensuring a perfect fit and maximum integrity, Assembly is fast, easy and cost-effective.

　　The resultant sandwich panel has a load-bearing capability many times greater than the achieved by adding together the load-bearing capacities of the individual layers. As a result, these thin, relatively lightweight sandwich panels can safely bridge wide spans. For Example, a panel just 100mm thick can easily bridge a clear span of some meters.
