Back to back channel and welded configurations
For the greatest design flexibility, combined with cost and time savings, Eaton offers one of the largest welded configurations of strut and welded combination strut/channel options available in the industry today.
These configurations and combinations can be incorporated into any project that employs Eaton’s B-Line series strut system, including B-Line series strut fittings.
Channel and strut made for long-term service and convenience
B-Line series channels are fabricated using components that are cold-formed in modern rolling mills. Metal framing channel is made from 12-gauge (2.6mm), 14-gauge (1.9mm) and 16-gauge (1.5mm) low-carbon steel strips. A continuous slot with inturned lips provides the ability to make attachments at any point.
- Slotted channel helps eliminate need for precise measuring for hole locations
- Eaton offers a variety of pre-punched slot patterns that eliminate the need for precise field measuring. These hole locations and slots provide a wide range to make adjustments when using hardware.

- Pre-punched hole patterns provide cost-effective means over field drilling
- B-Line series channels feature a variety of pre-punched 9/16" (14.3mm) diameter hole patterns
- B-Line series B217-20 closure strips provide cost-effective U.L. listed surface raceway
Core features
Quality-control testing means high-quality welding
The welding processes used for B-Line series back to back channel and channel configurations adhere to the standards of the America Welding Society (AWS) code. A statistical quality control program, combining destructive and nondestructive testing, is used to help ensure high quality welds on every B-Line series back to back channel configuration.
- Spot welding manufacturing drives consistency in design
- Spot welded back-to-back channel is manufactured using a DC powered resistance welder controlled by a microprocessor which produces a series of spot welds with speed and consistency. Variables such as weld sequence, speed and duration are carefully controlled and monitored by a sophisticated electronic control system.
- MIG welding provides quality weld on special configurations
- MIG welded, also known as gas metal arc welded (GMAW), combination channels and fittings, are produced when physical dimensions or certain combinations require a weld process other than automatic spot welding.

Quality assurance
Eaton’s quality assurance program is in compliance with ISO 9001:2008, as well as many other industry standards and specifications.
Materials and finishes
Unless otherwise noted in our strut system catalog, the material used is steel. Multiple finishes are available for maximum design flexibility. A minimum order size may be required for special materials or finishes. Finishes include:
- Plain - ASTM A1011 33,000 psi minimum yield
- Dura Green finish
- Pre-galvanized - ASTM A653 33,000 psi minimum yield
- Hot-dipped galvanized - ASTM A123
- Yellow zinc chromate - ASTM B633 SC3 Type II)
- Stainless steel Type 304 - ASTM A240
- Stainless steel Type 316 - ASTM A240
- Aluminum 6063-T6
Design load
The design loads given for strut beam loads are based on a simple beam condition using an allowable stress of 25,000 psi. The allowable stress results in a safety of 1.68. The safety factor is based on virgin steel minimum yield strength of 33,000 psi cold worked during rolling to an average yield stress of 42,000 psi. For aluminum channel loading, multiply steel loading by a factor of 0.38.
