A Leader in Commercial Stairs Since 1945

SY Stairs was formed from the partnership of Sentry Steel Inc. in Louisville, KY and Yokomori in Japan who, together, have a rich history designing and manufacturing stairs around the world. For over 70 years, we have pursued continuous innovation in every aspect of our stair system, giving you a product perfected over decades of experience unrivaled in the industry.

Our steadfast commitment to quality, safety, and customer service has earned us the trust of our clients, who choose us again and again to make their projects a success. We take pride in the fact that our stair system is used in 85% of the high-rise buildings in Japan, and that we are expanding rapidly in the US market is a testament to our ability to meet and exceed our customers’ high expectations.

A Focus on Thoughtful Design & Precision Manufacturing

We’ve invested heavily in the most state-of-the-art equipment and facilities to ensure we maintain the highest standards in the industry. Each project starts when our talented teams use our custom-developed 3D software to meticulously design and detail each project to enhance your stairs aesthetics and optimize construction efficiency. Our advanced production lines take data directly from our modeling software to automated fabrication lines with cutting-edge robotics to create error-free stairs.
