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.
