stainless steel products are made from high-quality austenitic Type 304
and Type 316 material. Stainless steel contains large amounts of chromium and nickel,
is non magnetic and offers superior corrosion resistance. Tolerant to high-temperature
environments, Superstrut’s stainless steel framing provides dependable support, resulting
in reduced maintenance cost. The channel is roll-formed to shape when cold, enhancing
its structural strength for the most rigid of applications.
Stainless Steel Channel
Elements of sections are the same as shown on pages B-200–B-210 for standard
steel channel. Load ratings meet or exceed ratings for standard steel channel shown
elsewhere in this catalog.
Additional stainless steel and aluminum items are available. Contact your local Superstrut
®
representative.
