Characteristics of quality steel bars produced by R.K

At R.K Steel Mills, following factors are considered during manufacturing of steel bars to ensure its bonding capability with concrete.

• Rib Spacing
• Height of Ribs
• Gap Cord
• Deformation
• Surface Scrapes

Any deviation in these parameters can significantly decrease bonding capability with concrete as well as strength of the bars.

Unit weight of steel bars is another factor that can significantly affect quality of construction as well as hurt the customers pocket. It is proven that manufacturing of steel bars under uncontrolled conditions or without supervision may produce over-sized or under-sized bars which may make them over-weight or under-weight bars respectively. Such bars when used in construction significantly hamper implantations of engineering-design as the weight and strength of steel bars varies considerably.

Such strict quality control standards and personnel expertise mentioned above resulted in RK branded bars being the prime choice for construction of dams, hydro-power plants, nuclear-power plant, bridges, motorways, factories, high-rise buildings etc.
