B-Line B52A-120GLV Eaton series strut back-to-back welded channel, .81" channel height, 120" channel length, 1.62" channel width, Steel, 12 Gauge, B52 channel type, Pre-galvanized

It's pre-galvanized steel, which is the standard finish for indoor and protected/dry locations. Pre-galvanized coating is applied to the coil before forming, so cut ends and weld seams are bare steel. For exposed exterior, corrosive, or wash-down areas, specify a hot-dip galvanized after fabrication or stainless channel instead.

B52 is the back-to-back welded configuration: two channel sections welded spine to spine so slots face both directions. That gives you a stiffer member for long spans and trapeze runs, and lets you bolt hardware on either face. A single-sided channel of the same .81 in height is the lighter choice for short pipe hangers or wall-mounted runs where you only need one usable face.

The B52A is a 1.62 in wide channel, which is the standard 1-5/8 in strut profile. Strut nuts, clamps, brackets, and fittings made for 1-5/8 in channel engage its slot in the normal way. The shallow .81 in depth means it is the half-height profile, so depth-specific fittings such as end caps and closure strips must be ordered for the shallow channel, not the 1-5/8 in deep one.

B52A-120GLV. The B52 is the back-to-back welded channel type, 120 is the 120 in length, and GLV designates the pre-galvanized finish.

Yes, 12 gauge steel channel cuts with a bandsaw, chop saw with a metal blade, or portable band saw. Because the finish is pre-galvanized rather than hot-dipped after fabrication, the cut end will be bare steel; touch it up with a cold galvanizing compound if the run is anywhere damp.
