Steel sandwich panel is a common building material with great heat and sound insulation. It also keeps the features of color steel, like high strength, excellent corrosion resistance, easy installation, light in weight, less maintenance, and attractive appearance. It is widely used in the roof and wall systems of industrial plants, warehouses, gymnasiums, supermarkets, cold storage, mobile houses, and other applications. Wanzhi Steel offers GI, GL, PPGL, PPGI sandwich panels with different designs, core materials, specifications, colors, and patterns, etc. Welcome to contact us for a free quote.

Insulated sandwich panels are extensively used as roofing or wall panels, from factories to malls, such as:
1. Industrial Buildings
2. Cold Storages
3. Agricultural and Husbandry Buildings
4. Worksite Buildings
5. Residential Buildings
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.
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.
At Wanzhi Steel, you can find various steel sandwich panels in different steel sheets, core materials, colors, patterns, specifications, etc. You will find the one suit for your needs the best.
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.
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.
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.
While choosing sandwich panels, you need to depend on the use purpose, environment, etc. to select the suitable core materials, steel sheet, coatings, thickness, even the color. Below are some tips. The outer steel sheet shall be resistant to weather, including temperature, wind, ultraviolet rays, etc. While the inner sheet may be influenced by chemical and physical effects, such as acid or humid environment. Wanzhi Steel has various options to choose from. If you are confusing, please contact us for more details!
