Tips for You to Buy Steel Bars!
Construction of house needs different materials and
hence needs study. The general guide points have been discussed by us in Material Buying Guide In General. Here we
discuss buying guide for steel.
One need to do adequate research when you plan to
buy steel bars. The steel bars are important for the life of the structural system. They are known as
rebars in short form. They are also known as reinforcing bar or reinforcement
steel.
Steel bars and cement are
the most important materials used in the building. The strength of building is
directly related to the strength of steel bars. We already discussed the cement buying guide in
our recent content.
a) Mild Steel Bars:
Mild steel bars are plain in surface and are round sections of
diameter from 6 to 50 mm. They can be manufactured in long length and can be
cut quickly and bend easily without damage.
Mild steel bars are
available in Fe410-S (Grade 60) or Fe410-O (Grade 40).
Medium tensile steel bars are available in Fe540 (Grade 75)
b) High Strength Deformed Steel Bars:
High strength deformed steel bars are
provided with lugs, ribs or deformation on the surface of the bar to improve
the bond with the concrete. They are also twisted to improve the bond with the
concrete.
Cold twisted deformed bars (Ribbed or Tor
Steel Bars) are recommended as best quality steel bars for construction work.
They are available in Grade Fe415, Fe415D, Fe500, Fe500D,
Fe550, Fe550D, and Fe600.
Fe indicates the
specified 0.2 percent proof stress or
yield stress in Newton per square millimeter.
You will have to
spend a lot of time towards reviewing types, brands and its grade while buying.
Quality and Specification of Steel Bars:
You can check the quality of steel bars by following steps
Buy only that grade of steel, as
prescribed in drawing.
Check the identification mark on the bars
from the manufacturing company.
Identification mark will be marked at every running meter of
the bar length.
There should not be any rust film on bars.
Always buy steel bars, which are rust free.
Check the diameter of the bar by vernier
calliper and it should be the same as specified in
drawing.
