Sustainability

Innovation for the Environment and a Sustainable Future — Free from Harmful Substances
Low-Carbon Aluminum
The more you use it, the cooler the planet becomes
ALNEX aluminum products are manufactured by a world-class extrusion facility with a fully integrated production process — from melting and extrusion to powder coating to anodizing. Backed by continuous research and development, ALNEX delivers high-quality aluminium for a transportation, and aerospace.

Using 6063T6 automotive-grad aluminium, which is 50% stronger than standard aluminium, every product combines strength with safety.
ALNEX is also the first in Thailand to be certified for both CFO (Carbon Footprint for Organization) and CFP (Carbon Footprint of Product), reducing greenhouse gas emissions by 4,500 tons annually — equivalent to planting over 150,000 trees, or approximately 28% below industry average.
ALNEX products are also non-carcinogenic, using Chromium 3 in production — a non-canncer-causing, essential trace element that enhances paint adhesion without harming people or the environment.
We believe that “strength” and “responsibility” should go hard in hand
That’s why ALNEX is committed to developing aluminium that’s not only durable and beautifully designed but also environmentally responsible — reducing carbon emissions and avoiding harmful substances for a stronger home, a cleaner planet, and a safer, more sustainable future.
