Mechanical crimping allows us to combine dissimilar materials in order to achieve a thermal, acoustic, magnetic or electrical decoupling. We use a special glass fiber reinforced polyamide (GRP) as web material and combine it with solid metals like mild steel and stainless steel for the flanges. Special metals such as bronze, copper and brass can also be used for the flanges. A stainless steel U-shaped adapter is fused to the flanges, and the GRP web is added by a continuous crimping process. This process squeezes the steel of the adapter against the web material, creating a strong frictional joint. The thickness and the width of the flanges can be specified according to the structural requirement. The GRP webs have a standard thickness of 1/8” and the height can be freely chosen. The manufacturing process for mechanically crimped profiles is very flexible, and this allows us the freedom to offer small minimum quantities for orders . For larger projects, it is possible to customize the GRP profiles by pultruding undercuts or dovetails into the web to accommodate special fittings like gaskets or seals.
Apart from standard geometries like wide flange beams, S-beams and tees we have the ability to create asymmetrical beams and double webbed beams for higher structural performance. These profiles can be produced with either sharp or rounded corners, and they come in lengths of up to 27 feet.
