Sandwich Panel
A sandwich panel is any structure made of three layers: a low-density core, and a thin skin-layer bonded to each side. Sandwich panels are used in applications where a combination of high structural rigidity and low weight is required.
The structural functionality of a sandwich panel is similar to the classic I-beam, where two face sheets primarily resist the in-plane and lateral bending loads (similar to flanges of an I- beam), while the core material mainly resists the shear loads (similar to the web of an I-beam). The idea is to use a light/soft but thick layer for the core and strong but thin layers for face sheets. This results in increasing the overall thickness of the panel, which often improves the structural attributes, like bending stiffness, and maintain or even reduce the weight.
Sandwich panels are an example of a sandwich structured composite: the strength and lightness of this technology makes it popular and widespread. Its versatility means that the panels have many applications and come in many forms: the core and skin materials can vary widely and the core may be a honeycomb or a solid filling. Enclosed panels are termed cassettes.

PU/PUR/PIR Sandwich Composite Panel.
As a green, environmental-friendly, light and high-strength new building cladding material, PU/PUR/PIR sandwich composite panel is a commonly used composite building material. The steel plates as outer skins offer this composite panel great strength, and the PU insulation material provides it with great thermal insulation, which is the best solution to energy conservation of buildings.
Glasswool & Rockwool Sandwich Composite Panel
Glass wool & Rockwool sandwich composite panel. The product uses high-quality glass wool& rockwool as the core material. Through the super long precision double-track curing, the product is excellent in terms of fire prevention, thermal insulation, noise reduction and environmental protection.
EPS Sandwich Composite Panel
In order to meet the suitable price requirement of buildings, the high-quality EPS sandwich wall panel. The product uses high-quality water-proof EPS as the core material. Through the super long precision double-track curing, the product is very good in terms thermal insulation, noise reduction and environmental protection.
Performance Description
Water Prevention:high-quality water-proof.
Thermal Insulation:the low coefficient of heat conductivity and the excellent node design guarantee the sealing performance and the thermal insulation effect.
Beautiful Design: multiple color , bright in color and attractive in appearance, there is no need to make the outer ornament. The panel adopts hidden-screw node design and has diversified panel effects.
Convenient Installation: Easy, flexible and fast. Compared with civil construction, it can cut down over 40% construction period.
Corrugated Steel Sheet
The most economical cladding for these structures is light corrugated metal sheeting, on both the roof and the external walls. These steel sheets, barely 0.5mm thick, are coated with an aluminum-zinc alloy for corrosion protection on both sides, and come with an attractive, durable paint finish on the outside. These sheets are installed over a grid of purlins, a steel member that rests on the main structural frame and supports the roofing material. In pre-engineered buildings, cold formed Z sections are the member of choice for purlins.
Before installing the sheets, contractors will install layers of insulation and vapor barriers. Rolls of glass wool or mineral wool are the most common type of insulation for such buildings. Since there is no inner wall over which to fix these layers, a layer of galvanized chicken wire mesh is first laid over the purlins. Over this, the insulation and vapor barriers are laid, and then the corrugated sheets are laid. The sheets are fixed with self tapping screws that run through the sheets and layers of insulation directly into the purlins. The purlins, chicken mesh and insulation are thus visible from below, and can be left as such or covered with a false ceiling. Polycarbonate skylights can be installed in the roof sheeting to create natural lighting.
It is common for industrial buildings to have a masonry wall upto a height of 2 to 5m. This allows doors and windows to be easily fitted, and provides security. This wall can be built behind the metal sheeting, making it invisible from the outside.
