**************************************************************************
NOTE: These paragraphs will be edited to retain
only the materials and finishes for the type of
rolling counter door required for the project. If
finishes other than those specified are required,
the specification will be revised accordingly.
Generally G40 minimum galvanized coating with prime
coat is sufficient for interior applications on most
projects. Aluminum or stainless steel should be
selected for esthetics. Aluminum should not be
chosen for high use applications. Fire rated doors
shall be constructed only of steel or stainless
steel.
Fire-rated doors are not normally available in sizes
as large as non-rated doors. Coordinate with
manufacturers on available heights and widths.
Add requirements for weatherstripping and
weather-tight installation for rolling counter doors
located on exterior walls.
