Grade 60 has a tensile stress of 60000 psi while Grade 40 has 40000.
Grade 60 steel rusts faster than grade 40.
grade 60 bar can be identified by the word 60 which should have printed on that while on grade 40 no no will be printed or written and we can identify this by counting the lines on steel as well.
If there are 3 lines longitudinally on the bar its is of 60 grade and if 2 lines longitudinally it will be identified as 40 grade.

Grade 60steel = steel with yield strength 60ksi or 60000psisimilarly grade 40 have yield strength of 40ksi or 40000psi
Epoxy-polyester powder coating is a hybrid of epoxy and polyester powder coating, and galvanised is coating thickness for steel bars and components is between 3 and 4 mils.
Steel companies make steel bars in circles
There are many companies and websites that offer steel bars for sale. Some of these websites that offer steel bars for sale are ULINE, Bodybuilding and Northern Tool.
Rod is circular in shape. If u look it from where it starts, i.e. its cross sectional view it will be circular. It may or may not be hollow. Bar's cross sectional view will be a quadrilateral. Shivangini
When steel bars are placed on both sides of a concrete beam, one side resists tensile forces and the other side resists compressive forces. The presence of tension or compression on top or bottom depends on the type of structure.
