HAZ Metal has designed an improved cast in channel to withstand dynamic loads with a cold-rolled channel. The HMPR-40/26 P has the same dimensions as the original 40/25 channel but with a wider radius for the purposes of bearing dynamic loads. With a stud that is wider and longer than the original version, the HMPR-40/26 P cast in channel can be used in applications where dynamic loads are specified. Elevator shaft connections, Machinery, and any connections that required dynamic loading can be connected with the HMPR-40/26 P channel.
