Structural Steel Building Systems

New Millennium standard steel joist products and bar joists are designed and manufactured at our six plant locations in accordance with the specifications of the Steel Joist Institute. All standard profile steel joists are available with either under-slung or square ends. LH-Series and DL H-Series steel joists are available with single-pitched or double-pitched top chords. The depth indicated in joist designation is determined by the depth of single-pitched joists at the center of span and at ridge centerline of double-pitched joists. When top chord slope exceeds 1/8':12', total and live top chord uniform loads must be provided. All standard profile steel joists will be furnished with standard SJI camber as indicated in SJI Table 103.6-1, unless specified otherwise in contract documents.

New Millennium special profile steel joist products and specialty joists are designed and manufactured at our six plant locations in accordance with the specifications of the Steel Joist Institute. We produce a broad range of special profiles, and make it easy to explore enhanced design possibilities.

Flex-Joist™ tension-controlled open web steel joist design gives building owners and specifiers the option of consistently higher steel joist performance at an affordable cost.

Increased steel joist performance metrics - when and where you need them Laboratory testing has consistently demonstrated the Flex-Joist™ design to exceed standard steel joist design for strength, reliability and ductility.

New Millennium engineers and manufactures the widest range of structural and architectural deck products and systems. Deck profiles are available in a variety of finishes and can be used in a wide range of applications requiring roofing and flooring and ceiling and cladding solutions. Deck products meet required steel deck certifications and are manufactured in accordance with the specifications of the Steel Deck Institute.

Type F (Intermediate Rib) roof deck provides an economical choice for applications where insulation requirements are lower. Where rigid roofing insulation is used with F deck, a minimum 1″ thickness is required.

Available with nested side laps only Type F roof deck is Factory Mutual approved for use as a component in Classes 1-60, 1-75 and 1-90 wind uplift construction. For additional information download FM Tables. When ratings above 1-90 are required, the Contract Documents must specify special requirements in accordance with Factory Mutual Data Sheet 1-29, Section 2.2.13

Steel Deck Institute Member Company fully approved to manufacture roof deck, form deck, and composite floor deck. F, B and N deck are Factory Mutual approved for use as a component in Class 1-60, 1-75, & 1-90 wind uplift metal roof decking construction. Steel 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.

The LEED (Leadership in Energy & Environmental Design) Green Building Rating System™ is a voluntary, consensus-based standard to support and certify successful green building design, construction and operations. LEED certification is available for all building types including new construction and major renovation, schools, healthcare, retail, homes, neighborhoods, core and shell, commercial interiors and even existing buildings.
