BM Steel Mill: Our Products BM Supreme

Deformed re-rolling bars have become the most easy and effective material in the field of construction during modern times. Almost all the residential and commercial buildings and complexes are constructed with deformed steel bars. The beauty of BM lies in: First; the ability of cement concrete to take the desired shape easily without causing cracks and, Second; its ability to resist all types of forces acting upon a constructed building.

Plain cement concrete without deformed bars is like meat and muscles of the body without bones. BM is ISO 9001:2015 Certified products. The graded products of BM Re-rolling Steel Industry posses the quality to tolerate various damaging forces, acting upon the buildings, making the buildings safe from cracks. The specifications of our products are given in the chart below.

BM Grade-40 Deformed Bars


Deformed bars with a grade 40 designation offers minimum yield strength of 40,000 pounds per square inch (PSI) and conforms to ASTM A-615 performance standards. Its metric counterpart is grade 280 re-bar, with equivalent minimum yield strength of 280 mega Pascal. This makes grade 40 deformed bars an excellent choice for light to medium duty concrete reinforcing applications.

Deformed Grade-40 bars of BM Re-rolling Steel Industry do not only fulfill the laid criterion but even exceeds limits after the laboratory tests.




BM Grade-60 Deformed Bars


BM Deformed A615 Grade 60 deformed bars increases the tensile strength of concrete, and can be used for both primary and secondary reinforcement. It helps absorb stress and weight, and facilitates the more even distribution of the tension caused by the expansion and contraction of concrete when it is exposed to heat and cold respectively.

ASTM A615 Grade 60 rebar is most commonly used in high-stress and demanding applications, and makes an economical choice in situations where a tremendous level of tensile strength is necessarily needed. Its strength and performance characteristics are grade dependent, and A615 rebar is available in a full range of standard sizes from number 3 to number 16.
