Name the frame and the secondary members
State whether the alternative should be a rigid frame in hot-rolled steel or a cold-formed steel system, and record the primary frame, secondary framing, purlin profile and girt lines.

CivicGate Sourcing does not select the member sizes; the quoting factory does, against the loads you supply.
