Basalt Composites: stronger, lighter, greener — transforming infrastructure, energy, mobility.

Why Basalt
Steel corrodes, rusts, expands and contracts, leading to cracking, spalling, and collapse.Buildings and construction account for 37% of global CO₂ emissions. Worldwide, 30-40% of infrastructure is rated poor or mediocre. The world urgently needs a structural material that endures and scales.
Promethean is a Global Platform for a Material that Outlasts steel and Reshapes Industries.

Technology
High-tech processes, low-tech origins – reshaping how the world builds
1.
Compliant with ICC-ES AC454 and tested to ASTM D8505 (BFRP rebar standard), with qualification under ACI 440 guidelines.
Certified by one of the world’s leading independent labs and code-writing authorities.
2.
Validated against Eurocode 2 guidance
Testing already completed, with compliance confirmation underway – including next-generation annexes, in direct collaboration with Eurocode developers.
3.
Proven durability
Tensile, modulus, bond behavior, creep, alkali and chloride resistance, freeze–thaw.
Vision
Our first target is 1% share of the $1.6 trillion global steel market. Promethean is building the platform to redefine global infrastructure. Governments and institutions, from sovereign funds to EPCs-that lead this transition will secure generational leadership in infrastructure and materials. Promethean is already working with partners across Europe, Africa, the GCC, and North America to drive the shift toward low-carbon, corrosion-free construction.
