The door is the main part of the building which provides safety and privacy. Different varieties of doors are available according to the material, manufacturer, etc. There are different types of doors like flush doors, sliding doors, revolving doors, collapsible doors, rolling shutter doors, etc.

A steel door allow us opening or passage into a house, building, room, apartment or closet by which persons enter. It is more strong other then normal wood door or others type of doors. Steel Doors

Steel or other such metal construction has been used for years as they are efficient and are a sturdy option for exterior and interior doors alike. These doors can be either be solid or hollow.

It has been found to be a good substitute for wood and is being used extensively for making frames. The frames can be made out of angles, Tee, channels or pressed steel plates. Holdfasts and hinges are normally welded to the frame in case of steel frames.
Normal shutters made out of wood etc can be fixed on these steel frames.

Steel frames are quite popular and are being used extensively for houses and other locations as they are economical than the conventional wooden frames.

Shutters can also be made out of Mild Steel (MS) sheets, welded or riveted to a frame of angle iron or channel section, properly braced.

Steel doors can also be made in high quality in cold rolled mild steel, precision engineered. They are long lasting requiring minimum maintenance. They are available in beautiful shades with various wood grain texturing.

These can invariably be used where security is of a greater concern.

Steel doors are widely used in houses, apartments and in places where door operating conditions require a higher resistance to loads, mechanical damages and corrosion. The use of metal materials does not preclude the creation of interesting and structurally advanced products. Well integrated doors may constitute an architectural detail that bonds the whole interior. The precision of performance combined with a high-quality powder coating in any color, enables manufacturing of a product adapted to individual needs.

TYPES OF STEEL DOOR

(A) INTERNAL DOOR

(B) EXTERNAL DOOR

(A) INTERNAL DOOR: This types of doors manufacturer specially for Passage of sound and fire are important criteria.

(B) EXTERNAL STEEL DOOR: This types of doors are designed specially for wheather resisitence and now it also comes in various designs

ADVANTAGES OF STEEL DOOR

They're relatively inexpensive and can offer the security and weather resistance of much pricier fiberglass and wood doors. Steel doors require little maintenance—unless dents are a part of your home scenario. They're energy-efficient, though adding glass panels cuts their insulating value.

DISADVANTAGES OF STEEL DOOR

Steel doors didn't resist weather as well as fiberglass and wood doors in our abuse tests and the laboratory equivalent of torrential rain, strong winds, and a decade of wear and tear. And while they're typically low-maintenance, dents are hard to fix, and scratches may rust if they aren't painted promptly.

PARTS OF STEEL DOOR

(1) FRAME:- It is an assembly of horizontal and vertical members, forming an enclosure, to which the shutters are fixed.

(2) SHUTERS:- These are the open able parts of a door or window.
