Steel Conduit Systems,mous extent for carcassing purposes on building sites. In spite of keen competition from ingenious alternatives, heavy-gauge screwed conduits probably are fitted in the majority of public buildings and factory installations. This is largely because of its great . and ease of rewiring.
