Concrete Spacers
Produced by Iran Concrete Technical Clinic Group (Clinic Beton Iran)
Brand: RBS-CONTECH
Overview
Concrete spacers are essential components in reinforced concrete structures, ensuring the correct positioning and coverage of reinforcing bars (rebars) within the formwork. High-quality spacers guarantee proper concrete cover, leading to enhanced durability, longevity, and load-bearing capacity for concrete elements.

Installation Guidelines
Select the correct spacer type and cover size as per project specification.
Position spacers at specified intervals to prevent movement during concrete pouring (typically every 500-800mm).
Ensure firm placement on stable and clean surfaces.
For vertical applications (walls, columns), use wheel/clip-on spacers. For horizontal elements (slabs, foundations), use chair/block spacers.
Quality Assurance
All spacers are manufactured under strict quality control according to international standards and regularly tested for strength, durability, and dimensional accuracy.
