Rebar Ground Stakes - Landscaping, Camping, Irrigation Trapping J, #4, 18 inch, 50pk, Size: #4 (4/8) SFS0_U4MCB13

Rebar (short for reinforcing bar) is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension. Rebars surface is patterned to form a better bond with the concrete. When added to concrete, the rebar adds strength and flexibility, which concrete alone does not have.
