B-Line Eaton series strut channel, 1.37" channel height, 240" channel length, 1.62" channel width, Steel, 12 Gauge, B32 channel type, Stainless steel

It is Type 304 stainless steel, not a plated or painted carbon channel. That matters for wet, washdown, coastal, and chemically aggressive areas where pre-galvanized or painted strut corrodes at cut ends and bolt holes. If the run is indoors and dry, a pre-galvanized channel does the same structural job for less.

Yes. At 1.62 inches across the open face, the B32 takes the 1-5/8 inch strut nuts, channel nuts, spring nuts, and pipe and conduit clamps built for standard strut. In a stainless install, pair it with stainless fittings and hardware, since galvanized or plain steel nuts in contact with 304 will rust and stain the channel.

Type 304 stainless is the usual choice for exterior, high-humidity, and food or pharmaceutical washdown environments because it resists corrosion without a sacrificial coating to breach. For chloride-heavy exposure such as pool chemical rooms or direct marine spray, specifiers often step up to 316 instead; 304 handles general outdoor and wet-interior duty.
