MSP is a fully integrated
steel manufacturer producing high grade TMT construction
rods. MSP uses fully killed steel manufactured from virgin
raw materials. The mill is technologically advanced and uses
automatic rolling to ensure the quality. All raw material
used is tested to ensure the high MSP quality standards.
Bendability, Weldability
and Bonding
Due to low carbon and strict
control over the highly advances Thermex TMT process MSP
Gold TMT bars do not lose strength at weld joints. It is also flexible
and gives high elongation. Due to the special design of the
bars they provide excellent bonding between the bar and
concrete for superior life.
Corrosion, Earthquake and
Fire Resistance
Cold twisting leads to stress
in the bars. Due to the special thermo mechanical treatment MSP Gold TMT bars are highly corrosion resistant and suited
for coastal areas. High ductility and elongation make these
bars earthquake resistant and suitable for use in seismic
zones 4 & 5. Due to its surface layer it resist huge loads
and can also withstand high temperatures of 500oC
to 600oC ensuring safety.
Cost Saving
MSP Gold TMT bars give value
for money. having excellent strength it saves steel upto 20%
over normal cold twisted bars. It is technically superior
and has high tensile strength.
International Standards
MSP Gold TMT bars are
manufactured conforming to various international standard
viz. IS : 1786 Grade Fe 415/ Fe500/ of BIS, ASTM A615
Grade 60 of USA, BST 500 of DIN 488 of Germany, BS 444
Grade 460 of Great Britain, among others.
