Our Products
Grade 60 and Grade 40 deformed steel bars (saria) in sizes 3–8 sutar — manufactured per PS 1879 and ASTM A615 standards.
Every Umbrella Steels bar passes through quenching, self-tempering and atmospheric cooling — creating a hardened outer core and ductile heart. The result: reinforcement steel with superior strength, earthquake-resistant flexibility and excellent concrete bonding.
Grade 60High-Strength TMT — 60,000 psi
The workhorse of serious construction. Grade 60 bars deliver minimum yield strength of 420 MPa, making them the standard for high-rise buildings, commercial structures, bridges and infrastructure where load capacity is critical.
Grade 40Ductile TMT — 40,000 psi
Maximum workability for residential construction. Grade 40 bars offer minimum yield strength of 280 MPa with outstanding ductility and bendability — the dependable choice for homes and general-purpose reinforcement.
Standard bar length 40 ft. Weights per PS 1879 nominal mass (d²/162.16).

The soft ferrite-pearlite core absorbs seismic energy, giving structures crucial flexibility under stress.
Precision-rolled rib pattern maximizes grip between bar and concrete for a stronger composite structure.
TMT bars retain structural integrity at elevated temperatures better than conventional bars.
Low carbon content allows clean butt and lap welds without loss of strength at joints.
Passes 180° bend tests without cracking — bends and re-bends safely during fabrication.
The tempered-martensite surface layer formed by water quenching resists rust in normal exposure.
