Mezzanines

Structural steel elevated platforms adding usable floor space within existing buildings.

29 manufacturers

Fabricated mezzanines are intermediate elevated platforms within buildings that add usable floor space without expanding the building footprint. They are constructed from structural steel columns, beams, joists, and decking (bar grating, concrete, or steel deck) with integrated stairs, handrails, and gates for material handling access.

Mezzanines FAQ

What load capacity can mezzanines support?

Standard mezzanine designs typically support 125 PSF (pounds per square foot) for storage and 150-250 PSF for manufacturing or heavy equipment. Custom designs can support significantly higher loads. Load capacity depends on the column spacing, beam sizing, and decking type specified by the structural engineer.
