This standard specifies the dimensions, manufacturing details, and material requirements for standard hot-rolled steel doors, windows, and ventilator frames. It is utilized by architects and engineers to ensure uniform, modular sizing and quality control during fabrication and site installation.
Specifies dimensions, materials and manufacturing requirements for steel door, window and ventilator frames.
Quick Reference Values

Practical Notes
This code specifies the frames themselves; for proper installation, fixing, and glazing guidelines on site, engineers must refer to IS 1081.
Always ensure the hot-rolled steel sections used by the fabricator explicitly conform to the profiles specified in IS 7452.
Steel frames must be properly treated for rust prevention and receive a priming coat of red oxide zinc chromate before leaving the factory.
