These roll-formed steel sections are 2" thick, hot-dipped and galvanized 25 gauge steel with a baked-on polyester finish. Section joints on these - and all C.H.I. doors - are tongue-and-groove for a tighter weatherseal and structural rigidity. They are also constructed with heavy-duty 18 gauge stiles for enhanced longevity.

The models 3251 and 3252 come with a polystyrene insulation with a vinyl backer and an R-value of 6.81.
