Expanded Metal Security Fabrication

Steel Masters NYC custom fabricates expanded metal and welded wire mesh security products for commercial, industrial, and institutional buildings throughout New York City. From security cage rooms and storage enclosures to expanded metal doors, window guards, and HVAC protection cages, every product is fabricated in our Brooklyn shop and installed by our own crew.

Expanded metal is the most cost-effective open metal product for security applications — stronger than wire mesh, allowing airflow and visibility while providing a genuinely impenetrable barrier. Steel Masters has been fabricating expanded metal security products for NYC buildings since 1972, serving restaurants, retail storefronts, warehouses, schools, hospitals, and government facilities across all five boroughs.

Expanded Metal Security Products We Fabricate

Security cage rooms and storage enclosures are the most common expanded metal request — full floor-to-ceiling cage rooms with lockable doors for storage, server rooms, utility areas, and controlled-access spaces in warehouses, schools, hospitals, and commercial buildings. Expanded metal security doors are fabricated with tube steel or angle iron frames and expanded metal or welded wire mesh infill — used as secondary security doors for basement entries, mechanical rooms, and storefront access. Window guards and vent covers use expanded metal panels welded into frames for basement windows, ventilation openings, and HVAC equipment protection. HVAC dunnage protection cages enclose rooftop mechanical equipment against theft and vandalism. Partitions and dividers use expanded metal panels to divide storage areas, separate loading dock spaces, and create secure zones within larger commercial spaces.
