ASTM A615 Concrete Rebar Grade 40

A615 grade 40 steel adds the most benefit when building materials must hold concrete in compression. Strength is one of the differentiators for these two rebar grades. The minimum tensile strength for A615 grade 40 steel is 70.05 ksi. It has a minimum yield strength of 40 ksi.
Product Description
Made of high carbon steel, both A-615 GR 60 and A-615 GR 40 rebar grades provide structural support to concrete and masonry constructions. They reinforce structures with strength and stability. With their reinforcement, they help prevent buildings and other structures from cracking, sagging, collapsing, or experiencing other unwanted and dangerous deformations. They do this by equalizing the distribution of tension and by absorbing stress. A-615 GR 60 and A-615 GR 40 reinforce concrete slabs columns in the architectural industry. They mainly benefit medium to heavy commercial applications such as walls, roadways, driveways, parking structures, brick buildings, and skyscrapers.
