Our Door Designs

Our Door Designs

Scientific Door

Scientific doors are designed to meet strict USFDA, WHO, and CGMP standards for clean and hygienic applications. They are ideal for industries such as pharmaceuticals, biotechnology, food and beverages, electronics, and hospitals, which demand high hygiene standards. Available in galvanized and stainless steel, these fully flush-type doors come with a variety of stainless-steel ironmongery, both domestic and imported. They can be customized with special features, vision panels, and a wide range of color finishes to suit specific project needs.

Scientific Door

Fire Rated Door

Fire-rated doors are crucial in buildings, factories, and commercial spaces for containing fires and saving lives and property. Studies show that smoke asphyxiation causes more deaths than the fire itself. Steel fire-rated doors act as barriers against fire and smoke, helping to restrict the spread of fires caused by arson, short circuits, gas leaks, or negligence, thereby saving lives.

Fire Rated Door

General Door

General steel door sets offer superior protection against vandalism, fire, and burglary, and require minimal maintenance. More robust than timber, PVC, or aluminium, they are favoured by residential and commercial enterprises for their design options and adherence to safety and security standards. These doors are durable, maintenance and eco-friendly.

General Door

Duct / Shaft /Access Door

Access doors, also known as access panels or shaft doors, provide secure entry in restricted areas. Available in various colours and with optional vision panels or louvers, they suit diverse customer needs. They are used in drywall, plaster, plumbing, electrical systems, valve boxes, floor hatches, security applications, and larger installations like roof hatches and walk-through doors. Duct access doors offer economical access to duct components, featuring insulated panels and gaskets for a tight seal. These doors come in hinged or double-cam constructions.

Duct / Shaft /Access Door

Louvered Door

Louvered doors are ideal for interiors requiring cross-ventilation. Uniquely designed to offer visual privacy and ventilation, they provide security for high-risk areas. Available in partial or fully louvered, single or double leaf configurations. These doors are used in maintenance rooms, utilities, power generator stations, electrical substations, swimming pools, office cabins, closets, plant rooms, and other commercial areas.

Louvered Door

Wood Finish Door

Metal doors offer significant advantages over traditional wooden or plastic doors. They are stronger, more secure, and available in a wide range of customizable designs, colors, and finishes to enhance aesthetic appeal. While wooden doors may initially appear more attractive and economical, they are prone to warping, bubbling, peeling, twisting, and bowing due to weather conditions, leading to frequent replacements and higher long-term costs. Considering these factors, metal doors are a prudent investment for both residential and commercial buildings, fitting seamlessly into any architectural theme.

Rockwool with Stiffer

  • High-density rock wool board insulation is made from molten basalt spun into fine fibers and bonded with a heat-resistant binder.
  • The rock wool infill board meets ASTM C-612 technical standards.
  • Optimized density, fiber direction, and excellent fit provide ideal thermal and acoustic insulation for steel doors.
  • Rock wool infill is used in steel-stiffened doors.
Rockwool with Stiffer

Polyurethane Core

  • Insulated foam is injected into the core, expanding to fill all available space within the hollow metal door.
  • Polyurethane offers the best insulation value but cannot be fire-rated.
  • These insulated doors are typically used for clean room applications.
  • Rock wool infill is used in steel-stiffened doors.
