Worried about warping in hot dip galvanizing





Hello

We have a project cladding (2) arched doors with (6) recessed panels on each face with 18 ga sheet steel. The final finish is specified as hot dipped galvanizing. The faces are lasercut the recessed panels are created with custom 18 ga steel molding, similar to a wood profile, the formed and welded cladding covers all faces of the 2" thick doors.
How concerned should I be with warpage from the heat with Hot Dipping them ?

Is there a lower temperature alternative that will look the same?
Would adding temporary reinforcement to the assemblies hold them in place for the heating process?
