All steel decking is available in lengths ranging from 6’-0” to 40’-0”. Extra charges are applied to lengths less than 6’-0”. Contact New Millennium if lengths exceeding 40’-0” are required.
Roof, form, and composite decking is manufactured from steel with a yield strength of up to 80ksi, conforming to ASTM A1008/A1008M for uncoated and painted deck and A653/A653M for galvanized deck. Refer to published tables for the minimum yield strength used for each deck type; contact New Millennium for availability of higher yield strengths when required.
Primer-painted or galvanized finishes are available for New Millennium steel decks. The standard primer-painted finish is gray on both the top and bottom sides. The galvanized finish is available in G30, G40, G60 and G90 coatings. Decks can also be furnished with a two-coat bright white primer bottom side combined with either a primer-painted or galvanized topside. 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 steel deck off the ground with one end elevated and protected from the elements with a weatherproof covering that is ventilated to avoid condensation.
Roof deck, form deck, and composite deck attachment to supports can be made either by welding using a minimum visible 5/8" diameter puddle weld or properly designed mechanical fasteners, spaced an average of 12” on center, not to exceed 18” on center. Weld washers must be used on all deck units that are less than 22 gage. Side laps are to be fastened together between supports at a maximum spacing of 36" on center whenever the deck span exceeds 5'-0".
All New Millennium decks are approved by UL, LLC and listed in the UL and ULC Fire Resistance Directories.
