Standard of steel rods

With the closure of the Chittagong Steel Mills, the private sector continues to thrive in the steel industry as producers of reinforced concrete bars or rods. These private mills continue to advertise in the media in respect of their supremacy in quality, endurance and durability, and rust proof. Reinforced bars are embedded in cement concrete. How can cement concrete endure earthquake shakes or vibrations as claimed by the advertisers? The standard of reinforced steel conforming to British, European, America, USSR, Japan, or India do not specify as claimed by our re-rolling mills in their ads. The BSTI should do something in this regard as the present BSTI standards do not specify bars as claimed by our steel producers.
