Lakshmi Metal Tech > Solutions > Commercial Steel Doors
We specialize in providing the steel door products for commercial and residential applications at the most competitive prices. These doors can be custom made to meet specific requirements like Vision Lites and Louvers in various sizes. Our commercial steel doors are complemented with a diverse assortment of the most commonly used architectural door hardware. This includes Hinges, Butt Hinges, Locks, Cylindrical Locks, Mortise Locks, Exit devices, Door Closers and Finish Door Hardware in both heavy duty and medium duty. We provide our steel doors with infilling of Honeycomb or Mineral rockwool.

  • Honeycomb Infill
    The core within the door gives it unique characteristics that may set it apart from another door that appears identical on the surface. When structural rigidity with light weightiness is the primary criteria of door requirement, honeycomb infill is the best option. Honeycomb was developed as a structural core for military aircraft wings during World War II and first used in standard metal doors in 1957. The rigid honeycomb structure is integrated with the door to form hundreds of small I-beams with the door, with a uniform thickness and flat surface that make it easy to add lites, louvers or other features. It reinforces the full width and height of the door thus avoiding steel stiffening of doors.

  • Mineral Rockwool Infill
    Rockwool infill is used in the steel stiffened doors. The high density Rockwool board insulation produced from molten basalt rocks spun to fine fibers and bonded with heat resistant binder. The rockwool infill board meets the requirements of the technical standard ASTM C-612. Steel stiffed door has vertical steel-stiffeners throughout the height of the door. The cavities between two stiffeners are filled with mineral rockwool. The combination of optimized density, fibre direction and excellent fit of mineral rockwool provides ideal thermal and acoustic insulation for steel doors.
