U 250 x 34,4 Tecnometal · Weight & Dimensions

Tecnometal, hot-rolled 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 250 x 34,4 (UK / Australia)
