B-Line Eaton series strut channel, 1.62" channel height, 240" channel length, 1.62" channel width, 12 Gauge steel, B22 channel type, Stainless steel t

This B22 channel is type 304 stainless steel rather than painted or plain galvanized, which is why it gets specified for food processing, washdown rooms, pool and natatorium spaces, and exterior runs where painted strut rusts at the cut ends. For chloride-heavy service, like coastal or pool chemical rooms, buyers often move up to 316; 304 is the standard corrosion-resistant grade.

Yes. The channel itself is 304 stainless, and mixing plated or galvanized nuts, bolts and fittings into it puts dissimilar metals in contact and gives you corrosion at every connection point, which defeats the reason you bought stainless. Spec stainless channel nuts, fittings and threaded rod to match. The channel does not come with any fittings.

Yes. B22 uses the standard 1-5/8 inch channel opening, so any 1-5/8 inch strut nut, conduit clamp, pipe strap or fitting seats in it. The difference between B22 and the shallower profiles is the 1.62 in back depth, not the slot width, so accessory fit is unaffected.

Eaton B-Line part number B22-240SS4. That breaks down as B22 channel type, 240 inch length, and SS4 for type 304 stainless.

Yes, 12 gauge is the standard structural thickness for B-Line strut and what most commercial trapeze and pipe support drawings call for. Lighter 14 and 16 gauge channel exists for light duty conduit and small runs. If the spec sheet says 12 ga 1-5/8 x 1-5/8, this B22 matches.

Field cutting is normal with 12 gauge strut, using a bandsaw or abrasive chop saw. Because the material is solid 304 stainless rather than a coating over carbon steel, cut ends stay corrosion resistant with no touch-up paint needed, unlike pre-galvanized channel where every cut has to be cold galvanized.
