Hollow Metal Doors
Our hollow metal doors combine 16/18-gauge steel construction with polystyrene or polyurethane cores for superior impact resistance. Channel-reinforced panels maintain structural integrity in high-traffic areas while fire-rated options provide up to 3-hour protection. These low-maintenance solutions outperform wood and aluminum alternatives in institutional and industrial settings.
Athletic Lockers
Engineered for schools and sports facilities, these lockers feature 1" double-pan construction with continuous piano hinges. The patented single-point latching system eliminates moving parts, reducing maintenance costs. Optional powder-coated finishes provide chemical resistance while perforated panels ensure ventilation.
Bathroom Partitions
Available in powder-coated steel, stainless steel, and HDPE materials, our partitions withstand extreme moisture and abuse. Stainless steel models contain 91% recycled content while HDPE options offer 25-year warranties. All designs meet ADA accessibility requirements with adjustable height configurations.

Custom-fabricated hollow metal frames accommodate various wall types with knock-down or welded assembly options. Fire-rated frames maintain integrity up to 3 hours while adjustable anchors ensure proper installation in challenging substrates. Available in 16 or 18-gauge steel with galvanized reinforcement.

Designed to allow natural light between rooms, our transoms feature 16-gauge steel construction matching door frame specifications. The welded box design prevents warping while accommodating various glass installation methods. Ideal for creating open yet partitioned commercial spaces.
