Back to Back Channels are structural elements used to support cavity walls above openings in construction projects. Two parallel flange channels (PFCs) are bolted together with a spacer in between, providing strength to the walls. The gap between the sections matches the width of the cavity, ensuring proper support and alignment.

These channels may be specified by structural engineers to provide greater support for brickwork or blockwork, enabling the support of both internal and external masonry. Depending on the design requirements, the spacing between the bolts can vary, typically around 600 mm from center to center. Back to Back Channels offer flexibility in spacing due to the C shape of the channels, allowing for closely twinned configurations or wider separation with spacers. They can be supplied primed for painting and customized with service and timber holes for easier installation. Back-to-back steel channels are commonly used in various applications including structural support beams in buildings, bridges, warehouses, and machinery. The strength and stiffness of these channels are influenced by factors such as size, thickness, and cross-section shape, ensuring they can effectively support significant loads in construction projects.
