3 QUALITY ASSURANCE DECK PRODUCTS New Millennium Building Systems produces a wide range of floor and roof deck at the Butler, Indiana and Lake City, Florida manufacturing facilities. Our Salem, Virginia location will also be producing deck by the third quarter of This catalog contains information on all the products currently being produced, for use by specifying engineers and architects. The load tables shown herein have been calculated using Allowable Stress Design. Deck is available in lengths from 6'-0 to 50'-0. Extra charges are applied to lengths less than 6'-0. DECK FINISHES New Millennium Building Systems offers primer-painted or galvanized deck finishes. The standard primer-painted finish is gray on both the top and bottom sides. The galvanized finish is available in G40, G60, & G90 coatings. Deck can also be furnished with a two coat bright white primer bottom side combined with either a primer-painted or galvanized top side. The primer-painted finish is intended to protect the steel for a reasonable installation period while exposed to ordinary atmospheric conditions and shall be considered an impermanent and provisional coating. Always store deck off the ground with one end elevated and protected from the elements with a weather-proof covering that is ventilated to avoid condensation. DECK CERTIFICATIONS Steel Deck Institute Member Company fully approved to manufacture roof deck, form deck, and composite floor deck. B deck is Factory Mutual approved for use as a component in Class 1-60, 1-75, & 1-90 wind uplift steel roof deck construction. Deck products are approved by Underwriters Laboratory and listed in the UL Fire Resistance Directory. All acoustical deck has been tested in accordance with ANSI ASTM C423 & E795 to determine the noise reduction coefficient (NRC) rating. 171

Type B deck provides the best balance of strength and economy of all the 1 1/2" deep roof decks. 1" (minimum) rigid roofing insulation is required to be used with type B deck. Available with nested side laps only. Available as an acoustic deck. Type BA deck is manufactured with perforations in the vertical ribs, having a NRC rating of 0.60 with 1 1/2" (minimum) rigid roofing insulation. Available as a vented deck. Type BV deck is manufactured with slot vents in the bottom flutes. The openings equal 0.5% of total surface. Type BV deck is to be specified when venting is required for cementitious insulation fills. Type BV deck is manufactured at our Lake City, FL facility only. Type B deck is Factory Mutual approved. Type BA and BV decks are not Factory Mutual approved. Type B, BA and BV decks are manufactured from steel conforming to ASTM A Grades C, D or E or from A653/A653M-00 structural quality grade SQ33 or higher. The minimum yield strength used by NMBS is 33 KSI. Minimum attachment to supporting structural members requires connections at all side lap ribs plus a sufficient number of interior ribs to limit the spacing between connections to 18. Side laps are to be fastened together between supports, at a maximum spacing of 36" o.c. whenever the deck span exceeds 5'-0". Connections can be made either by welding using a minimum 5/8" diameter puddle weld or properly designed mechanical fasteners. 172

Perforations which are placed in the vertical ribs of type NA deck reduce the strength less than 5%. Type N deck is well-suited for applications where it is desirable to space the supporting members as far apart as possible. This is often the case in structures such as gymnasiums where it is usually more economical to minimize the number of long span structural members by using type N deck to span large spaces. Available with nested side laps only. Available as an acoustic deck. Type NA deck is manufactured with perforations in the vertical ribs, having a NRC rating of 0.65 with or without rigid roofing insulation.

Connections can be made either by welding using a minimum 5/8" diameter puddle weld or properly designed mechanical fasteners. Side laps are to be fastened together between supports, at a maximum spacing of 36" o.c. whenever the deck span exceeds 5'-0". Side lap connections can be made by button punching. 187
