History of R.C.C Door Frame

It was some 30 years back Central Building Research Institute, Roorkee and National Building Organization, New Delhi (both Govt. Of India research organizations) were engaged in developing door & window frames of a versatile building material other than wood. Govt. Of India has always encouraged use of substitute building material for wood in order to save forest wealth & environment.

For windows rolled steel sections, pressed steel sheet sections, aluminum sections & lastly fiber glass material were found to be the best alternatives. However for doors, RCC Door Frames were found to be the best & last option. The ease of casting in three pieces, usage of quality moulds to obtain precise dimensional accuracy & super smooth surface revealed that conventional wooden door frames can be conveniently replaced by precast RCC Door Frames.

Studies & researches finally recognized the suitability of RCC Door Frames which compelled Bureau of Indian standard to formulate standard specification of RCC Door & Window Frames (IS: 6523 of 1983).

Most of the manufacturers of precast RCC Door Frames belong to Vidarbha region. Reason being the sand required for RCC door frames has to be super fine & silt less. It is Kanhan, Pench, Vainganga rivers in Nagpur district where the required quality sand is available. Attempts from other regions for manufacturing the RCC door frames with available sand from nearby rivers were failed as the product did not meet expectations.

The item of RCC Door Frames have been included since long in the Schedule of Rates and Specification of CPWD, PWD (Maharashtra), other State PWD, MES, HUDCO,CIDCO, Indian Railways, MHADA, Housing Boards of Maharashtra & other States, PSU & other Semi Govt. Departments etc.
