Stainless Steel I Beams

Penn Stainless Products supplies stainless beams in 304/304L and 316/316L. Stainless beams are primarily rolled or extruded up to 6″ height x 3.332″ flange with web thickness up to .232″. See our catalog for full product details. Larger beams in excess of 6″ can be manufactured utilizing laser fusion technology, which also enables engineers and metal buyers to mix thickness or even material grades. Laser fused beams can also be supplied in Duplex 2205 and lean Duplex 2101.

All beams can be cut to size. Stainless beams can be supplied with a polished finish. Contact a sales associate for details about processing stainless steel beams.
