Over the last 30 years, the Govt. of India has recognized & encouraged the use of sub tute building material for wood in order to save forest wealth & environment. The Central Building Research In tute, Roorkee and National Building Organization, New Delhi (both Govt. Of India research organizations) had been engaged in developing door & window frames of a versatile building material other than wood.
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).
Through research it was found that for Doors, RCC Door Frames were the best o on. The smooth surface finish, precise dimensional accuracy & the ease of Casting were the prime features that put RCC Door Frames at a much advantageous Position as compared to Traditional wooden door frames
