Packaging: Signode
strapping in bundles of 5 tonnes.
Rounds are available in straight lengths.
Plain Rounds/ TMT bars/ TMT-HCR rebars in sizes 8 and 10 mm are available
in coils. The other sizes of Plain Rounds/ TMT bars/ 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.
