I suppose you could drill and tap holes for attaching this plate to your frame as you would on an aluminum frame, but I would not recommend it as it would be my concern that the long term integrity and safety of the hinge reinforcement installation would not equal the long term installation benefit of welding the place to the frame.
I am familiar with these parts and the process of installing so if there a follow up question that we can perhaps attempt to answer? We take pride deep in our technical expertise, as we know it separates us from our competition, so don't hesitate to ask.
