director-img Welcome to sigma

On behalf of Sigma Elevator Company and its affiliates throughout the world, I’d like to welcome you to our web page.

Sigma has a history dating back to 1968, when the first elevator company in Korea was founded. More recently, in 1999 (following the acquisition by Otis), we started doing business under the “Sigma” trade name.

We take pride in meeting the needs and demands of our customers, and have a strong commitment to producing the world’s best elevators and escalators. Sigma has an unique heritage that leverages the strengths of the pioneering legacy of its founding company, as well as its current ownership.

Sigma has exported over 50,000 units to more than 70 countries worldwide. Today we have an unmatched distribution network in 46 countries all over the world. We have several new and unique products that have been developed by our experienced engineering team, including technology made available to us through our affiliated Centers of Excellence. We have also taken advantage of more than 40 years of industry experience to develop a portfolio of safe and reliable products.

Everyday, millions of people ride on our elevators and escalators, and we strictly take our responsibility to ensure absolute safety for our passengers. Our goal is to provide a smooth, convenient and safe ride for all people riding our elevators and escalators. We are constantly investing to improve our technology and developing new and innovative products to ensure that we uphold our company’s values.

We promise that we will give our best efforts to satisfy your needs with Sigma’s products and services.

Thank you.

Sigma Elevator Company, Managing Director
