B-Line B22SH-240SS6 Eaton series strut channel, 1.62" channel height, 240" channel length, 1.62" channel width, Steel, 12 Gauge, SH hole pattern, B22 channel type, Stainless steel type 316

It's type 316 stainless steel, not a plated or painted carbon channel. That's the grade you want for coastal, wastewater, chemical, and washdown environments where 304 or plain galvanized strut will pit. The base material is listed as steel in 12 gauge, finished as stainless steel type 316.

B22 measures 1.62 inches high by 1.62 inches wide, which is the nominal 1-5/8 by 1-5/8 profile. So it takes the standard 1-5/8 strut nuts, clamps, straps, and fittings a contractor already stocks.

Salt air, chlorides, wastewater treatment, pool decks, food processing washdown: that's where 316 stainless earns its cost, because galvanized strut will bleed rust at every cut end and slot edge. For a dry indoor mechanical room or an interior conduit rack, pre-galvanized B22 does the same structural job for less. This B22SH stick is the 316 option at 12 gauge.

SH is the slotted hole pattern punched through the back of the channel, as opposed to a solid, unpunched back. The slots let you through-bolt the channel to structure, hang threaded rod, or join channel to channel anywhere along the run instead of only where you drill. If your spec calls for solid-back strut for maximum section strength, SH is the wrong pattern to order.

The manufacturer part number is B22SH-240SS6 from Eaton's B-Line series. Reading the code: B22 channel profile, SH slotted hole pattern, 240 inch length, SS6 for type 316 stainless. That's the number to put on a submittal or a purchase order.

Yes, it's cut to length like any strut, but use a stainless-dedicated blade or wheel. A wheel that has touched carbon steel embeds iron particles in the cut and those rust spots will show up within weeks on a 316 channel. Passivate or clean the cut edge after. Each stick is 240 inches, so you're typically getting several hanger lengths out of one piece.
