i bought these for wooden frame house building. then the first job i utilized them on was on a steel frame building. i cut 4 x 2×4 pieces of wood and routed out the sides to fit over the i beams , then screwed the veneer clamps to the wood. using a sliding clamp to lock it onto the i beam and adjust to where i wanted to use my profile. WAS WELL IMPRESSED WITH THE RESULT. would recommend all of your products to any bricklayer who wants to make money. would have given it a 10 just cant stop smiling.
