Hollow Metal Frame
Hollow metal frames are engineered to provide maximum strength, durability, and fire-rated performance for demanding commercial environments. Fabricated from cold-rolled or galvanized steel, these frames are designed to accommodate a wide range of wall conditions, including drywall, masonry, and steel stud construction, ensuring reliable integration across different building types. Available in both welded and knock-down (KD) configurations, hollow metal frames offer flexibility in installation, with KD frames designed for post-drywall applications and welded frames providing a rigid, pre-assembled solution with seamless, ground-smooth corners. Reinforced hinge and strike preparations, along with multiple anchor options, ensure compatibility with standard and heavy-duty hardware systems. With fire ratings ranging from 20 minutes up to 3 hours, adjustable jamb depths, and precision manufacturing, hollow metal frames deliver a complete, high-performance solution for commercial openings where strength, safety, and long-term durability are essential.
