Introduction
Sections made of various materials are rolled or drawn out of semi-finished goods such as billets or bars, and in many cases they are also welded from bar material. They are used in a vast number of applications, requiring a wide variety of mechanical tests. Together with the reinforcing steel and ribbed reinforcement bars (rebars) so vital to civil engineering they form a group of important structural materials, which in the case of concrete-reinforcing steel, are subject to regulatory control.
List of Material covered are as follow:-
- Reinforcement Bars & TMT Steel as per IS 1786
- Structural steel as ISMB, 1SMC, Plate, Beam (IS: 2026)
- Section (I, L and channel section)
- Cast Iron & MS pipes as per IS: 1161
- LDPE Sheets as per IS 2508
- Multilayer Cross laminated sheets as per IS 14611
- Fumigation Covers
- Aluminium Section Complete Test (IS: 733, 737)
- Aluminium Product, Anodic Coating (IS: 1285, 5523)
- Stainless Steel, Complete Test (IS; 6911)
