U 166.4x60x3.2 Acindar · Weight & Dimensions

Acindar, cold-formed sections · Cold-formed Channel

Cold-formed channels (U shapes) are similar to C shapes but without stiffening lips. Used for light structural framing, supports, and secondary members.

Also known as: U 166.4x60x3.2 (UK / Australia)
