Uses of Steel Sandwich Panel

What Is Sandwich Panel?

A sandwich panel is made with a core of thermal insulating material and is covered with two pieces of metal sheets. Our sandwich panels use GI, GL, PPGI, PPGL steel sheets. GI sandwich panel will be cheaper than the PPGI sandwich panel. Generally, the types of sandwich panels are grouped by core materials, for example, EPS (expanded polystyrene),  PIR, RW, XPS, PU, and PF. The main differences between them lie in their fire resistance, sound-heat-insulating performance, etc.

Benefits of Color Steel Sandwich Panel

1. Easy Installation

Its lightweight and beautiful appearance make it easy to install. Figures show that a worker can install 150 m² per day. Besides, there is no need for secondary processing, which can shorten the construction period. A building using the traditional material may take 6 to 7 months to complete. While if using steel insulated sandwich panels, it needs only 1 to 2 months.

3. Durability

The corrugated sandwich panel keeps the strength of steel, which is strong and durable to use. Both PPGI PUF panels and GI sandwich panels are corrosion resistant so that they are suitable for different use environments. Especially, we use fluorocarbon paint for color-coated sandwich panels, which largely prolong its service life. Also, it is almost free of maintenance.

4. Heat & Sound Insulation

Compared to the PPGI roofing sheet, PPGI sandwich panels has an excellent thermal resistance. The λ-values range from 0.024 W/(m·K) for polyurethane to 0.05 W/(m·K) for mineral wool. The temperature difference is more than 10 degrees. It is suitable for both extreme cold and hot conditions.

5. High Fire Resistance

A sandwich panel will slow down the spreading of fire to ensure the safety of life and property in the building. Please note that for fire insulation aims, you need to take the core material into consideration.
