They suit very well in the handling of heavy loads. Our shipping container flooring aluminum extrusions are very tough, thanks to the alloying elements, heat treatment and the design. By using the best profiles, we manage to achieve the best strength-to-weight ratio. The result is a product that can rival even some that use steel. Apart from the strength of the alloys which is good, the design also determines how much the extrusions can hold. Important elements that we consider are wall thickness and the uniqueness of the shape.
