solidian GRID Carbon is an ultra-strong, lightweight and corrosion-resistant carbon grid reinforcement for load-bearing concrete components.
Our carbon grid reinforcement solidian GRID carbon has a tensile strength several times higher than classic steel reinforcement meshes. The carbon fiber composite reinforcement does not corrode and is extremely lightweight. These positive properties lead in part to considerable cost savings in construction, maintenance and repair. The lower material consumption (up to 50 % less water, aggregates and cement) when using our carbon reinforcement grid, as well as the great potential for saving on transportation costs and CO2 emissions, make it a truly sustainable solution. With solidian GRID, concrete goes from gray to green!
solidian GRID is the first carbon reinforcement grid approved by the German Institute for Building Technology (DIBt) through a General Building Authority Approval (abZ) including a General Construction Technique Permit (aBG). Based on the abZ/aBG and the newly published DAfStb Guideline “Concrete Components with Non-Metallic Reinforcement”, solidian GRID reinforcement can be used as single-layer or multi-layer tensile reinforcement (up to 6 layers) in concrete components. Carbon reinforcement grids with an abZ/aBG are designated in accordance with the requirements of the DAfStb Guideline. Detailed information about the General Building Authority Approval can be found here on a dedicated page.
Product Features
Advantages
- Slimmer components: Enables slender construction with unique aesthetic design possibilities.
- Lower transportation and storage costs: The lightweight reinforcement itself can be transported in rolls and enables lighter, thinner precast concrete elements.
- Deflection: No higher deflection of the components compared to steel due to a similar modulus of elasticity.
- Resource efficiency: Lower consumption of concrete and therefore less use of water, aggregates and cement.
- Safer and easier handling: The lower weight ensures safer and healthier handling during processing.
- Minimal disruption to operations: Less disruption to operations due to less maintenance and repair work.
These properties make our non-metallic reinforcement the ideal choice for modern, sustainable construction projects.
