The PU sandwich panel has some featured advantages:

1. Outstanding climate-resistance and temperature-adaptability

The steel plate of the panel is a kind of cold-rolled, after degreasing, phosphating, chromating the surface is coated by organic coating and made by baking. The coated layer can stand high temparture without any change of color, it has no peeling when being bent or punched. The surfaces of the plate is coated by polyester paint, this makes the surfaces of the panel very wear-resistant, acid-resistant, alkali-resistant and salt-resistant, oxidation protection, and anti-rusting. Such climate-resistant panel have a good durability of useage for over 15-20 years.

2. Good performance

The core layer in the middle of the panel is shaped by special binder and pressed at a high temperature. The bulk density is 15kg/m3 for EPS foam panel, 35kg/m3 for PU panel, 120kg/m3 for rock wool panel, the material is non-poisonous and fireproof, sound insulation and heat-insulation, anti-corrsive, steam resistance.

3. Light in weight and easy to process.

The panel is light in weight and easy to process. Its core board is of low density, high intensity and high toughness. Because of the panel is light in weight, it will reduce the damage in earthquakes and be transported easily. Besides, the panel is very easy to process, so the cost of the project will be reduced.

4. Various colors

The board is rich in color style, which provides many selections for customers. It can also be adjusted according to clients request, and satisfy the varied designs of the architects.
