Low-Carbon Aluminum
The more you use it, the cooler the planet becomes.
ALNEX aluminum products are manufactured by a world-class extrusion facility using fully integrated processes — from smelting, extrusion, and powder coating to anodizing. Continuous research and development ensure that each product meets diverse needs, from architectural applications to automotive, electronics, and aerospace industries.
We use high-grade automotive aluminum 6063T6 (T6), which is 50 % stronger than conventional aluminum, ensuring superior safety and performance.
Our production is certified for both Carbon Footprint for Organization (CFO) and Carbon Footprint of Product (CFP) — making ALNEX the first in Thailand to achieve both certifications. We have reduced greenhouse-gas emissions by 4,500 tons per year, equivalent to planting over 150,000 trees, or approximately 28 % below the industry average.
In addition, ALNEX products are non-carcinogenic, produced with Chromium 3, a safe element essential to the human body, used in place of harmful substances. This process enhances paint adhesion to aluminum while maintaining environmental safety and long-term durability.
Because we believe that “strength” and “responsibility” must coexist.
ALNEX continues to pioneer aluminum innovations that combine durability, design, and environmental care — reducing carbon emissions and eliminating harmful residues for a stronger home, a cleaner world, and a safer, more sustainable future.
