PU Sandwich Panels are composed of 3 layers, the external and internal is two dyed Galvanized or Aluminum corrugated plates, and core Polyurethane (PU) rigid foam. Due to the advantages as heat and sound insulation, high load capacity, light weight (about 10kg/m2), quick movement and easy to install, PU Sandwich Panel are procured with the best prices and used in the buildings whose load-bearing system is of steel and prefabricated concrete, such as industrial buildings, military buildings, social buildings, agricultural buildings, sports facilities, construction sites, silos, hypermarkets, shopping malls, cold storage depots and marketplaces. The products to meet the requirements of any kind of architectural project are produced with aluminum or dyed galvanized sheet metals, in requested amounts and dimensions at BRD Sandwich Panel.

SUPER FLAME RETARDATION
The coefficient of thermal conductivity is 0.023w/(m.k), which ensures better thermal insulation efficiency. In practice, this effectively keeps the building absorbing heat and brings enormous economic benefits.

PU sandwich panels are applied as external walls and internal division walls, installed vertically or horizontally on single- or multi-span structure. Thanks to its hidden joint the panel ensures very aesthetic look of the wall or façade.
In particular the panels can be applied in
Industrial buildings,
Store houses and logistic centres,
Commercial buildings and offices,
Food industry facilities,
Agricultural objects
Sport halls.
Sandwich Panel Assembly
1, First of all, it must carry on the construction preparation before installation, include personnel, materials, etc. All will be well prepared.
2, Before the installation of wall panel, it should check whether the verticality and levelness of metope purlin installation requirements, wall frame column vertical degree meets the requirement.
3, Before installation polyurethane wall panel, it should first mounting plate bottom water retaining plate and the bottom of the window to block water board, water retaining plate and wall frame beam connection with self tapping screw fixation.
4, Polyurethane wall panel links with ground.
Lateral links: fixed polyurethane sandwich panel with the ground at the other end of the round hole with steel frame fixed, connection between the two plate mouth involution, if occurrence crack of the connectors available heat preservation to fill.
Vertical links: the gap between plates, using the dedicated button concave groove in the fixed wall panel.
