It is very nice to meet you on our website. I have been with the members and employees of SEJIN Technical Industries Co., Ltd. for many years and have undergone the challenges and achievements of the company directly. The company had to visit leading companies and asked for technical support at the time of establishment. It enjoys the current fame and status in the industry thanks to efforts for continuous technology innovation and hard work and efforts of all the executives and employees. SEJIN Technical Industrial Co., Ltd. has made spectacular growth by overcoming repeating crises and taking them as an opportunity and, now, it is ready to advance beyond the limits. It will be the leading ‘Total Accommodation System’ in this field. Our employees and I will comply with the ethical and social responsibility through compliance management to the domestic and international laws and regulations and fulfill our duties as a global leader to allow harmonious coexistence of man and nature with the best products and technologies. Thank you
