Sri Ranga Grating Works is a Chennai-based manufacturer of industrial steel gratings, founded by G. Adimulam in 1998. Our works at T.S. 50A, Thiru-Vi-Ka Industrial Estate, Ekkattuthangal supplies welded bar gratings, serrated non-slip gratings, heavy radial gratings, trench covers and stair treads to projects across India.
Every grating is designed to carry the desired live load (UDL) apart from its self-weight, in conformance with IS 800 and the National Building Code. Configurations are normally rectangular but we routinely produce circular and special shapes with cut-outs and toe plates to match the floor profile.
