Round-chair spacer Arman Abzarbeton

Spacers are efficient components in the building industry that bring many other advantages besides creating the right rebar cover. Spacers or spacers of various sizes are designed and manufactured to create rebar covers from 15 mm to 150 mm. The most important weakness of a reinforced concrete structure is the corrosion of the bars. Air, moisture, chlorides, sulfonates and other corrosive environmental agents can penetrate the concrete into the concrete, which in turn will cause serious damage to the structure. One of the most important factors in preventing corrosion of concrete is to provide proper coating on the bars with structural and weather conditions. Experience has shown that the use of stone, brick or wood pieces as a barrier between the rebar and the concrete surface has never been able to create a proper rebar coating on the rebar surface, in which case it is usually due to the lack of integrated rebar coating. Areas where the coating has been reduced due to the lack of anchor sizes are more likely to corrode. Spacers are efficient, affordable and lightweight components that can provide seamless coverage on the rebar surface.

Advantages of using spacers:

• Creating an integrated coating on the reinforcement surface
• Economical, Affordable and Cheap
• Lightweight, easy shipping
• Accelerate spacing to cover rebars
• Need less manpower
• Speed ​​of execution and thus speed of project execution
• Complete concrete collision due to the presence of hollow holes in the structure or the failure of the rebar to move due to the lock in the spacer
