rebar spacer and His role in insurance the reinforcing steel



A rebar spacer is a device that secures the reinforcing steel or "rebar" in reinforced concrete structures as the rebar
is assembled in situ before the ultimate concrete pour. The spacers ar left in situ for the pour to stay the reinforcing in situ, and become a permanent a part of the structure.
the concrete spacers have the advantage of identical staple which can improve the watertightness and strength of the concrete. Plastic spacers have the advantage of the low price production and quick process.
reinforcement spacers or rebar spacer
The spacers ar left in situ for the pour to stay the reinforcing in situ, and become a permanent a part of the structure.
The main classes of rebar spacers are:
Linear Spacers (Π-section profiles, H-section profiles, or other 3 dimensional shapes)
Point Spacers (wheel spacers, various tower or chair-like shapes)
Rebar spacers can be divided in three raw materials categories:
1)Concrete spacers
2)Plastic spacers
3)Metal spacers
