Hybrid profiles are made by combining dissimilar materials in order to achieve a thermal, acoustic, magnetic or electrical decoupling. On a beam, for example, Montanstahl uses a special glass fiber reinforced polyamide (GRP) as web material and 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. In a first step a very precise stainless steel U-shaped adapter is fused on the flanges. The fixing of the GRP web is achieved by a continuous crimping process which squeezes the steel against the web. The result is 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 hybrid profiles is very flexible and allows us to produce small batches of only 2000 lbs. For larger projects it is possible to customize the GRP profiles by pultruding undercuts or dovetails in to the web to accommodate special fittings like gaskets or seals.

Apart from standard geometries like wide flange, S-beams and tees we have the ability to create asymmetric beams and double web beams for higher structural performance. For technical reasons, it is necessary to maintain a minimum distance from the edge of the flange when joining with the web (5/16”). Furthermore we are in the process of developing hybrid sections made from dissimilar materials for thermal, acoustic, magnetic and electric isolation.

This technology is the same as the press fit technology but adds flexibility in the inclusion of dissimilar materials. Again, prior to joining, the individual flat components can be polished which is more cost-effective than polishing a complex shape. The maximum production length is 40 feet with a maximum profile width of 7-7/8" and a height of 15". Small sections down to 2” x 2” can be produced as well.
