About Dorsmith

Dorsmith doors have been at the forefront of design and manufacture of bespoke steel doors for the commercial, industrial and public sectors. Designs have been developed by our experienced in-house team to provide customers with door and frame solutions that offer high performance and quality with long life and low maintenance.
STANDARDS :Dorsmith designs and manufactures doors as per ANSI ,SDI&CPWD Standards.
We manufacture all steel doors at our production plant in Puducherry using up to date computer technology and modern machinery under the stringent control of the ISO 9001 quality system. This enables us to supply a variety of specifications depending on the application required together with a wide range of options and sizes complete with factory-fitted hardware for ease of installation.
A beneficial byproduct of the strength and durability of hollow metal is the low total cost of ownership. Properly installed and maintained hollow metal doors often last 30 years or longer. As the years pass, steel doors can be inexpensively repaired in the field while softer, less durable wood and aluminum doors will have to be replaced.
Today’s steel doors offer endless options for attractive appearances. Whether you are looking for a modern stainless steel appearance, a vibrant colored finish, or even a faux finish, steel’s versatility allows it to satisfy the aesthetic requirements of most projects. And don’t forget all those advantages of performance and longevity!
Steel doors and frames even help the environment, as steel is the most recycled material in the Planet.

Unique Operations

SANDING
Sanding ensures the honeycomb is the proper thickness to fit within the door panels. The sanding also increases the surface area to which the contact adhesive can be applied, therefore improving the lamination.
EXPANDING
Expanding the honeycomb ensures that the cell structure is at its optimum size. Honeycomb strength is determined by the cell size and structure.
RESIN IMPREGNATION
The kraft honeycomb material is impregnated with a phenolic resin. The phenolic resin enhances the honeycomb by making the material resistant to decay, insects and vermin. The resin also makes the honeycomb resistant to moisture. The amount of the impregnation is controlled to prevent a brittle condition.
CURING
The honeycomb must be fully cured to ensure the strength, moisture, decay, vermin resistance and bonding strength are achieved.
ADHESIVES
Contact adhesives are used to bond the impregnated honeycomb to the door panels. Since contact adhesives are designed to adhere to one another, the contact adhesive is applied to both door panels and to both faces of the honeycomb. By coating all surfaces in their entirety a true bond is achieved across the width and height of the door.
BONDING
A true bond is further ensured by passing the door and honeycomb assembly through a pinch roller process that exerts 500 pounds pressure per square inch.
POLYSTYRENE
Polystyrene solid core doors mounted in a frame that has been fully weather-stripped will provide an efficient insulating assembl for extreme weather conditions. The tested U-factor of the asser is .23.
POLYURETHANE
Polyurethane solid core doors mounted in a frame that has been fully weather-stripped are designed to provide efficient insulating assembly for arctic weather conditions. The calculated U-factor the door is .09.
Baked-On Prime Paint
All Steel craft doors are supplied with a baked-on prime paint fini in accordance with ANSI A250.10. Before applying the primer, ft doors are thoroughly cleaned and phosphatized to ensure proper paint adhesion. The primer is an attractive, environmentally friendly neutral beige color and is suitable for field-applied finish paints.

Wall Anchors

Corner Connection

DRYWALL FRAME
Drywall frame corners lock together as the frame is installed. The tab design prohibits the head from raising and keeps the head and jamb members in the same plane.
FLUSH FRAME
Flush frame corners are designed to lock together by bending over four integral tabs. The frame can also be welded and ground smooth.

Handing

To determine the hand of a door, view the door from the outside(the side that hinges are on is the hand of the door).
If the door swings away from the viewer, the hand is regular hand, i.e., right or left hand.
If the door swings to the viewer, the door is reverse swing or left hand reverse swing.
