Wheatland controls the manufacture of its hot dip galvanized steel rigid metal conduit (RMC), electrical Metallic tubing (EMT) and Intermediate metal conduit (IMC) every step of the way. we fabricate our own tubing from flat steel coils, weld it and do our own galvanizing. Then to be sure you get the same quality throughout the raceway system, we make our own nipples, elbows and couplings to match. in fact, we're the only conduit manufacturer who does.
