blend of premium polyester resins and silicone. 'SP' provides a <br />high resistance to ultra - violet rays as a durable coating over <br />G -90 (1.25 oz [275 g /m2]) galvanized steel. 'SP' shall meet the re- <br />quirements of a long -term exterior finish with.excellent weather- <br />ability. 'SP' finish shall provide an optimum use of silicone to- <br />gether with a premium quality polyester resin for long life. Alter- <br />nately, the panel shall be color coated in fluorofinish which is a <br />premium fluorocarbon called polyvinyledine fluoride, (KYNAR 500 70 %). <br />It is applied to G -90 (1.25 oz [275 g/m2]) galvanized steel. Exterior <br />performance characteristics should include color integrity, film flexi- <br />bility and resistance to chalking. Other important properties of finish <br />shall be high resistance to ultra - violet radiation, and resistance to <br />weathering. <br />The panel profile that is encouraged to be used is deep profile rib <br />18 gauge minimum run horizontally. Maximum permissible deflection is <br />to be 1/120. Hat shaped and "Z "- shaped subgirts should be placed at <br />every structural support and not more than C-011 (1.22 mm) on center <br />between supports. Trueness of material and quality of workmanship, <br />with proper detailing of material termination, shall be of the utmost <br />importance. <br />7. Plaster: <br />Smooth plaster (stucco) may be used but is not highly recommended <br />because of uncertainty in surface quality control. If plaster is used, <br />- 7 - <br />8 -218 <br />
