Great Grandeul Steel (GGS) company founded by Mr. Kuo Weilin and his son, Mr. Kuo Yungcheng started as a steel trading company in 1974. Within six years of our inception, GGS had launched a coil service center and had added cut-to-length and slitting services. In 1992, GGS independently developed a unique electrogalvanized (EG) sheet production line. GGS service centers provide customers with readily available inventory, value-added metals processing, reliable and timely delivery, flexible minimum order size and quality control. On top of that, GGS has a diverse EG sheet offerings including both chromate-free phosphated and anti-finger print EG steel sheet products. Over the past 40 years, GGS has grown together with China Steel and today established itself as one of the industry benchmark companies in Taiwan’s steel industry.

Great Grandeul has an in-house electrogalvanized steel production line. EG steel sheets manufactured through a series of processes of de-greasing, electroplating, and surface treatment find applications in steel furnitures, home electronics, and communication electronics owing to its excellent corrosion resistance, weldability, and paint adhesion.

GGS is committed to meeting customer expectations in terms of both quality and delivery as well as building and maintaining strong relationships with our customers and suppliers. It is our mission to always develop and respect collaborative partnerships and find opportunities for innovation and research. It is also our top priority to create a working environment that makes our employees proud.
