Rounds are available in
straight lengths. Plain Rounds/ TMT rebars/ TMT-HCR rebars in sizes
8,10 and 12 mm are available in coils. The other sizes of Plain Rounds/
TMT rebars/ TMT-HCR rebars are available in straight lengths.
High
Temperature Strength
SAIL TMT-HCR
reinforcement bars exhibit higher thermal resistance even at
temperatures up to 600 0 C. The retention of significant
strength or, in other words, resistance to softening, is attributed
to design of steel chemistry, presence of tempered martensite layer
on the rebar surface and absence of any cold worked structural zone.
Thus the thermally hardened SAIL TMT-HCR rebars are ideal for use in
places prone to fire hazards.
