After serving for over 30 years as the feet of global villagers,the former LG Elevators and Escalators of LG Industrial Systems Co.,Ltd.lives on with the birth of Sigma Elevator Company.

On the basis of time-tested and valuable expertise, our everlasting ardor for customer satisfaction under the banner of "New Technology," Perfect Quality," and "Best Services" will be sustained by SIGMA Elevator in the new millenium.

BBirth of " SIGMA Elevator "

We are proud to introduce a new generation of escalators with our SCE series.Sigma Commercial Escalators are well suited for today’s urban structures. New technologicaladvancements have been applied to make the escalators the world-best in design and safety.New technology and aero-dynamic design make Sigma escalators appealing while improvedstrength and safety features offer security to users.Manufactured by the Changwon factory in Korea, Sigma escalators will continue to meetstringent customer requirements with higher goals than expected.With certificates to meet various standards around the world, we offer the best quality andsafety with Sigma escalators.
