Crimped Sections

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.
