Sandwich panels are composite materials made of two thin panels or skins, usually made of metal, plastic, or composite materials, and core material in between them. The core material is usually made of foam or a lightweight honeycomb structure, which helps to provide insulation and structural support to the panels.
The weight of sandwich panels can vary widely depending on the size, thickness, and type of materials used in construction. Generally, sandwich panels are lighter than traditional solid panels because they use less material overall. However, the weight of a sandwich panel can also be influenced by factors such as the density of the core material, the thickness of the skins, and any additional features like coatings or insulation layers.
As a general guideline, sandwich panels made with foam cores tend to be lighter than those made with honeycomb cores. For example, a 50mm thick sandwich panel with a foam core and 0.5mm thick metal skins could weigh around 3-4 kg/m2, while a panel with a honeycomb core and the same skin thickness might weigh around 6-7 kg/m2. However, these numbers are just estimates and the actual weight of a sandwich panel can vary depending on the specific materials used and the panel's design.
The weight of sandwich panels per square meter produced by polyurethane sandwich panel production line can vary depending on several factors such as the thickness of the panel, the type of core material, and the type of facing material used.
On average, a sandwich panel with a thickness of 50mm - 100mm and made with a polystyrene (EPS) or polyurethane (PU) core, and steel or aluminium facing sheets, can weigh between 10 kg/m2 and 20 kg/m2.
However, it's important to note that this is just an estimate, and the weight may vary depending on the specific type and brand of sandwich panel manufactured by the sandwich panel production line. It's always best to check the manufacturer's specifications for the exact weight of the panel you are considering.
