    Rolled Steel Beams and HPS 70W Steel

    Is it possible to get W18, W14 rolled beam shapes in HPS 70W steel or are they available only in Grade 36W and Grade 50W steel. I am trying to minimize my section depth due to hydraulic concerns on a small bridge project. Any help would be greatly appreciated. Thanks!

    Drilled Caisson/Rock Socket Costs

    I am doing a project for a DOT in the Pittsburgh area. I am looking for costs for a 9'-0" drilled caisson rock socket (20' in length) and a 10'-0" drilled caisson (about 40' in length). I found information for smaller diameters but would like to know how much the costs increase for the larger...

    HPS 70W Costs

    I am doing a project for a DOH and utilizing HPS 70W steel. My question is what price per lb. is HPS 70W steel versus Grade 50W? Also, are there any limitations to the length of HPS 70W steel? I am working with plates sizes up to 20"x 1" and 26" x 1 3/8". Thanks
