DSI Underground Systems Inc. can bend I, WF, H sections ranging from 4" to 27" in depth (DSI has formed W14x287 lb ft with 2" flanges). Curvatures range from a minimum radius of 10 times the beam depth for 4" and 6" sections to 14 times the depth of section for larger beams. While DSI Underground Systems Inc. has worked with 30' sections, it is recommended the sections not exceed 22'. DSI also recommends against the use of lighter-weight sections when the radius of curvature is less than 25 times the depth of section.

 

DSI Underground Systems Inc. also fabricates straight beams, forepoling sheets, steel lagging, tie rods, foot plates and pipe spacers.
