Round Rebar Mesh Up Chair

A rebar chair is a type of support used in reinforced concrete construction to maintain the proper spacing between the reinforcing steel bars, also known as rebar, that are embedded within the concrete.
The chair is typically made from metal wire or plastic and is designed to hold the rebar at a specific elevation and distance from the ground or formwork, as specified in the construction plans.

The rebar chair has a basic structure of legs that support a circular or square base, which in turn supports the rebar.
The legs of the chair may have varying heights to accommodate different concrete depths, and the base may have different shapes and sizes to accommodate different bar spacing requirements.

Rebar chairs are essential in ensuring that the reinforcing steel bars maintain the correct position during concrete placement and curing.
Improper placement or spacing of the rebar can compromise the structural integrity of the concrete and potentially cause catastrophic failures.
The use of rebar chairs helps to ensure that the reinforcing steel is correctly placed and supported, which enhances the strength and durability of the concrete structure.
