Load-bearing capacity is always taken into consideration when choosing the type of sandwich panel to be used on buildings. Agents such as self-weight, wind load, the weight of snow and heat or a combination of these agents have an impact on buildings. 

Sandwich panels are composite materials consisting of a polyurethane/rockwool-filled core between two metal sheets and their behaviour under different weights must be carefully taken into consideration. 

Metal surfaces of limited elasticity and core filling materials can barely carry their own weight as simple substances. However, when it is a composite material thanks to resistance to slide and bending, a new system emerges with a load carrying capacity that increases in every layer.

Strength of sandwich panels’ filling material and their trapezoidal shape are crucial in determining load carrying capacity.
