STELMAX Steel Spacers (Steel Chairs) maintain correct spacing between rebar mesh layers. Unlike bricks, they don’t shift during concreting, ensuring structural strength and preventing cracks.
STELMAX Steel Chairs are engineered to provide consistent reinforcement support under construction loads. Unlike temporary site-made supports or bricks, they offer accurate spacing, improved stability, and better structural performance.
