PU Sandwich wall panels are widely used in commercial and industrial building construction as external wall. Due to the excellent performance of the insulation, PU(polyurethane) sandwich panels are commonly adopted for heat insulation and deadening applications in these buildings,such as food cold stores,industry halls, warehouses, logistic centers, offices, sport halls as well as rural buildings.
Wemet Industry’s sandwich panels consist of two steel sheets facings and an insulation core.Panel facings are made of galvanized steel sheet, coated with polyester paint, thickness from 0.3 to 0.7 [mm] made in accordance with norm PN-EN 10346:2009. The steel we use to produce our panels are delivered by top china steel suppliers.
The core of the panel can be made of polyurethane (PUR) foam with density of about 40 ± 2 [kg/m3] or more is produced by our own factory.
It is a highly heat insulating wall plate system with excellent flexural capacity. It is preferred for the walls of high-end buildings

Product advantages of PUR(polyurethane) sandwich wall panels
1. The products are connected by blind nails and have no exposed screws on surfaces, promising beautiful and smooth appearances for walls of buildings.
2. Their extremely great flexural capacity and excellent mechanical properties can lower the dependence on auxiliary steel structures
3. Their excellent heat preservation performance can cut down the cost of the interior air-conditioning devices of buildings.
4. There are multiple appearance effects (ripple effect, plat effect, relief effect and square wave effect) for your choice to make wall surfaces beautiful
5. Energy-saving & insulated
Excellent insulation properties (average thermal conductivity is 0.020W/m.k). In the protective effect of formula and outer color steel plate based on the stable condition, in three years, its thermal performance can still keep its first 180 days of the above thermal insulation performance of 95% core obturator rate >=97%
