Engineering That Performs
Where Others Cannot

The SALBEN material Lineup

GRC | GFRG | BLOCKS | UHPC — unmatched strength, complex geometry, and long-term durability.

What is GRC/GFRC

Glass Fiber Reinforced Concrete - Salben's Core Discipline.

We design and manufacture architectural facade panels, decorative elements, and custom GRC/GFRC structures — a material that combines exceptional strength, low weight, and virtually unlimited freedom of form and texture. Production strictly adheres to international GRCA standards.

Delivering the complete cycle: from structural calculations and engineering to manufacturing, logistics, and on-site facade installation.

We Don't Just Manufacture
We Deliver

SALBEN Group supports projects from concept to completion.
Our engineering team works directly with architects, structural engineers, and site managers to ensure
that every GRC/GFRC element is designed, produced, delivered, and installed correctly.
We do not simply manufacture panels and hand them over. We are a project partner.
