FIRE RATED DOORS

COMMERCIAL DOORS

METRO commercial steel doors are manufactured corresponding/adhering to the specifications set abroad with quality as its backbone and tested with internationally recognized laboratories such as UL and BS. As standard, the doors are 44 mm thick, made of premium galvanized metal sheets or Galvalume for the door panels (Ga18 or Ga20 depending on the requirements), doors are insulated with either Rockwool, honeycomb, Polyurethane foam or fiber glass for sound deadening, and most importantly, for fire retardant purposes. Door frames are fabricated from Ga16 premium galvanized metal sheets or Galvalume with 3 standard models. As standards, steel doors and frames are primer coat finished.

Flush/ Plain

The term “flush,” when used to describe a door type, refers to a door without glass or louvers. (PLAIN TYPE)

Half glass doors

Doors with glass located at the upper half of the door face;

In accordance with ANSI/ICC A117.1, doors containing one or more glass panels shall have the bottom of at least one glass panel a maximum of 43″ from the finished floor.

Full glass doors

A maximum 7″ rail and stile occur at the top and at the vertical edges of this door. An 8″ minimum rail occurs at the bottom.

To comply with ANSI/ICC A117.1 specification, the bottom rail shall be specified as minimum 10” measured vertically from the floor and shall be a smooth surface on the push side extending the full width of the door.

Narrow lite door

The glass cutout in these doors are located near the lockset. The width of the glass glass size and glass location from the finished floor to the glass opening will vary with the door size or specifications.

Louvered/ Grille door

There are a number of louvers and grilles available. The choice of which one to use must be determined by the architect on aesthetic, functional and economic grounds as well as fire protection. A louver is an opening in the door with a series of non-visionary slats or blades to allow passage of air. This louver frame is inserted into the opening in the door prepare to receive the louver. Fusible link louvers are used to control passage of flames and heat.

Louver Windows

Louvers are commonly installed in doors or used as windows; a louver is basically an assembly of slanted blades designed to permit airflow from one area of the building to another. The amount of air from movement through the louver depends on the louver profile. Metrotech Steel Industries, Inc. manufactures and supplies different types of louvers depending on the requirements of the specific area or architectural specifications.

Louvers Manufactured to Fit Your Requirements

Metro louvers are manufactured through a series of metal forming process rather than through a metal roll forming/extrusion process. Our process gives us the flexibility required to custom manufacture your louver requirements according to size, louver profile, design, tolerances, etc.

As our standards for louvers, we manufacture using Ga.18 galvanized steel, however other materials and thicknesses are available.

Why Galvanized Louvers?

Galvanized louvers are economical and effective choice for many applications. Galvanized steel (coated with a layer of zinc) is corrosion resistant and remains rust free for decades. Galvanized louvers have excellent weather resistance, making it suitable for exterior exposure. The zinc alloy coating on galvanized steel is also abrasion and impact resistant, and harder than base steel. Overall, galvanized louvers are stronger than their mild steel or aluminum counterparts.

Metro louvers, as standard, are primer coated. However, we can also supply in powder coated, lacquer painted, or acrylic painted depending on the client’s request and specification.

Galvanized Louver Types

Over the years, Metrotech Steel Industries, Inc. has developed different profiles of louvers depending on its application. Although generally the louvers are custom fabricated to fit your needs, we classified our louvers into several categories:

• Interior Louvers: Recommended for areas requires low velocities of air. Usually installed in interior applications.
• Heavy Duty Louvers: Reinforced to withstand high velocities of air. Recommended for Exterior applications.
• Patented-Storm Louvers: Designed to withstand strong winds and water from entering your building. Recommended for exterior applications.
• Patented-Acoustic Louvers: Insulated to minimize noise/sound while serving its function as ventilation. Recommended for gen-set rooms.
