ASTM A615 Concrete Rebar Grade 40
Steel Rebar
ASTM A615 Concrete Rebar Grade 40 Description
Manufactured from 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, among others.
