CONSTRUCTION: The 900 Series is constructed of 24 gauge pre-finished galvanized steel. Horizontal meeting rails are rolled-formed with a shiplap joint acting as an integral strut and weather joint. Section faces are deep ribbed for added strength. End stiles are "U" shaped formed from 18 gauge galvanized pre-painted steel and completely encloses and protect the end of the door from damage and also serve as a flat smooth service for exterior weather seal. 18 gauge galvanized intermediate stiles are permanently attached at each end as well as midpoints as required for long life and rigidity. Bottom section is furnished with a full width aluminum reinforcing angle/retainer fitted with compressible loop-type weather seal design for continuous contact at sill.
