About G-Max I&C
A company that grows together with its customers.
Welcome to G-Max I&C
Since 2001, G-Max has been a company specializing in digital keyphones with creative caller-ID technology, built on research and development with leading engineers from around the world, including the United States. Today we are recognized as one of the top three keyphone makers in Korea, and we sincerely thank our customers, agencies and distributors.
Our growth is the result of our customers’ generous support, the help of our agencies, and our own utmost efforts under the company motto:
“Customer satisfaction is our mission. A policy for the best quality. Creative and advanced technology.”
As a result, the company received the Grand Prize at the Seongnam Small and Medium Venture Business Awards and was selected as one of the promising small and medium companies in Gyeonggi-do.
In April 2009 the company changed its name from Maxtel Keyphone to G-Max I&C as part of its effort to become a specialist in both wired and wireless communication. Our corporate R&D center carries out intensive research in both fields.
Alongside keyphone systems, G-Max has developed and released the Smart TV Player, a UWB wireless docking station and a PLC surveillance camera. We wish everlasting growth to all of you.
