Daeho-al is preparing for the new future with a competitive advantage in the market.


Daeho-al is specialized in the manufacture of aluminum coils, sheets and high-quality circles as its key products.
As for coils and sheets, they are used as industrial materials (EV, ESS, LED TV, Mobile Phones, Refrigerators and Auto Parts), whereas circles are delivered to kitchen utensil companies and LED lighting companies by meeting their requested physical properties of the circles.
We have built the production system for small batch and multi-variety thanks to know-hows on aluminum sheet production, which results in increasing customer satisfaction through the short lead time to cope with a rapidly-changing market demand.
