IS 1038:1994 is the Indian Standard (BIS) for steel doors, window and ventilator frames. 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.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
