Concrete Castle Mesh Block Spacers

Our castle mesh spacers are expertly crafted from high-strength fibrous concrete, delivering outstanding durability with a minimum concrete strength of 50N/mm². Designed to meet the rigorous standards of BS7973-1:2001, these spacers ensure precise rebar placement and optimal concrete cover, which are crucial for concrete projects' structural integrity and longevity.

Their high compressive strength, precise dimensional tolerances, and resistance to temperature fluctuations ensure long-lasting performance. With superior physical and chemical resistance, they bond seamlessly with in-situ concrete, preventing hairline cracks and are suitable for waterproof concrete. They are also fire-resistant to EN13501-1:2002 Class 1A standards, making them a reliable choice for site and precast concrete applications.
