B-Line Eaton series runway tubular, 119" height, 119" length, 6" width, Steel, ASTM A513 steel, 11 gauge, Tubular stringer, Yellow zinc

Yes. The rungs are 1/2 x 1 steel channel, welded to the tubular stringers, so the section arrives as a finished ladder rack piece. You do not assemble rungs in the field; what you still need to buy separately is the mounting hardware, splice kits and wall or ceiling supports for your run.

Yellow zinc is a plated finish over ASTM A513 steel, intended for dry indoor use such as equipment rooms, telecom closets and data centers. It is not a coating for wet or corrosive exposure. If the job spec on the drawing calls out a painted or hot dip galvanized runway, the yellow zinc version is not a finish substitute.

One section weighs 23.6 lb bare. Add the cable load you plan to run when you size threaded rod, trapeze supports or wall angle spacing, because in most telecom runs the cable bundle far outweighs the 11 gauge steel rack itself.

Order Eaton B-Line part number SB1606AYZ. That covers the 6 inch wide tubular stringer section in yellow zinc with welded rungs. Width is the number that changes across the family, so confirm 6 inch is what your pathway drawing calls for before you commit the quantity.

A tubular stringer uses closed steel tube side rails, which gives a cleaner look and a smooth edge for cable to lay against. Flat channel or tubular versus solid bar racks differ mainly in how accessories clamp on and in the look above an open ceiling. The SB1606AYZ is the tubular type in 11 gauge ASTM A513 steel with welded 1/2 x 1 channel rungs, so accessories you buy must be rated for the tubular stringer profile.
