SPAN - DECK is manufactured by a precision casting process providing dimensional control and uniformity unattainable in other concrete materials. Lengths are sawed rather than formed so that dimen- sional accuracy is assured to meet PCI Design Handbook tolerances. Because of larger core areas and thinner surface thickness required, SPAN -DECK weighs less per square foot than other similar concrete decking units available. As a result, SPAN -DECK offers reduced footing and foundation design require- ments and a lower section depth to span ratio. Load tables on the following pages will confirm this. SPAN -DECK has a smooth, steel -formed ceiling. A variety of textures are available at a nominal cost. r• In many floor applications, SPAN -DE.CK may be used without additional concrete topping. joints between slabs are grouted, suitable underlayment or padding applied, and finishing carpet, 1 - d floor, or the installed. SPAN -DECK is .n ideal material not only for floors, ceilings and roofs, but also for wall panels. Being plant fabri- cated, SPAN -DECK can be quickly erected year -around in virtually any climate. USE Of VOIDS SPAN-DECK's large core areas have been used for electrical raceways and for forced air supply and return. SPAN -DECK core areas are easy to penetrate for whatever application you have. Simply use a ham- mer and chisel, a core drill, or lust a hammer. rr r `FIRE SPAN -DECK meets the conditions for the i- re.w restrained and unrestrained fire rat- ings criterion of ASTM E119 and is listed by Underwriters Laboratories, Inc., for two-_ our tire -resistant classifications (un-__,:•>; topped), restrained and unrestrained con- ditions. Three and four-hour ratings are also available with the use of field cast -1 topping. See design numbers J914, 1915, J916, J917, 1918, 1949 and 1952 in U. L. Building Material List. ACOUSTICAL PROPERTIES ■--SPAN-DECK's hardiock surfaces and hot- , low cores resist air -borne noise and transmission of impact noise to provide Jqualities superior to those of a solid con- Crete slab of equivalent thickness.
