B-LINE B22SHA-240GLV – Frequently Asked Questions

1) What size is B22 strut channel and will standard 1-5/8 strut nuts and fittings fit it?
B22 measures 1.62 inches in both height and width, which is the standard 1-5/8 inch strut face. Fittings, spring nuts, and channel hardware built for 1-5/8 inch strut engage the open face normally. What makes B22 different from a single 1-5/8 x 1-5/8 channel is that it is two channels welded back to back, so you get an open slot facing both directions and roughly double the section for load.
2) What is the exact part number for B-Line 20 foot back-to-back B22 pre-galvanized strut?
The Eaton B-Line part number is B22SHA-240GLV. Read it as B22 channel, SHA hole pattern, 240 inch length, GLV pre-galvanized finish. If you need a different length or a solid back, only the middle and trailing segments of that number change.
3) What does the SHA hole pattern mean on B-Line strut channel?
SHA is B-Line's designation for the slotted hole pattern punched in the channel back. It gives you pre-made openings to bolt the strut to structure, beam brackets, or another piece of strut without field drilling, and it lets you thread all-thread or hanger rod through the back where a solid channel would force you to drill. If you want a solid-back channel with no punching, SHA is the wrong suffix.
4) How heavy is a 20 foot stick of B22 back-to-back strut and can one person handle it?
Each 240 inch length weighs 72.8 pounds, so it is a two-man carry at minimum and realistically a job for a lift or pipe rack when you are setting it overhead. At 20 feet the stick also wants support along its length when it is moved, since the weight is spread out and the ends will flex and whip.
5) Is pre-galvanized strut channel OK for outdoor or wet locations?
Pre-galvanized (sometimes called mill galvanized or GLV) is a zinc coating applied to the steel coil before the channel is rolled and punched, so the cut ends and the punched slots are bare steel. It holds up well indoors, in parking structures, and in covered exterior work. For direct weather exposure, chemical process areas, wastewater plants, or coastal sites, spec hot-dip galvanized or stainless instead, because those protect the cut edges too.
6) Why use back-to-back welded strut instead of two single channels bolted together?
The welded pair acts as one section, so there is no slip between the two halves and no line of bolts to install, torque, and inspect. It also gives you a channel slot open on both sides for mounting equipment on either face. Bolting two singles together gets you close on strength but costs you labor and adds hardware in the load path. For a single run of conduit or light pipe, a single 1-5/8 channel is plenty and back-to-back is overkill.
7) What gauge steel is this B-Line strut and is 12 gauge the heavy-duty version?
It is 12 gauge steel, which is the standard heavy-duty thickness for structural strut channel. Lighter 14 and 16 gauge channel exists for light conduit and low-load hanging; 12 gauge is what you use for equipment racks, trapeze hangers carrying large conduit banks, and mechanical equipment support.
8) Can I cut this 240 inch strut to length in the field?
Yes, it cuts with a bandsaw, chop saw with an abrasive or metal-cutting blade, or a portaband. Because the zinc is applied before forming, the fresh cut leaves bare steel, so hit the cut ends with a cold galvanizing compound if the run sees any moisture. Deburr the cut too, since 12 gauge steel leaves a sharp edge.
