U 40x40x2 Tecnometal · Weight & Dimensions

Tecnometal, cold-formed sections (Italy) · 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 40x40x2 (UK / Australia)
