Commercial hollow metal borrowed lites are constructed from corrosion resistant galvannealed steel and are adaptable to drywall, masonry, or concrete wall designs. They are widely used in offices, schools, hospitals, retail spaces, and industrial facilities they are typically installed in areas where creating a full window opening is impractical or where security must be balanced with light transmission. These frames accommodate various glass types making them perfect for non-fire rated and fire rated openings while providing a practical solution that combines light transmission, visibility, and safety.
