In modern architectural spaces, staircases have long been more than merely functional components for vertical movement. They also serve as artistic carriers that interpret spatial aesthetics and highlight architectural style. Founded in 1990, SINE STAIR started as a small family wooden staircase workshop in Xishui, Hubei Province. Over more than three decades of development, it has grown into a professional staircase manufacturer integrating the design, production, installation and service of curved staircases.
The company boasts a sound organizational structure with six functional departments: R&D Department, Technical Department, Inspection Department, Production Department, Sales Department and Customer Service Department. Equipped with professional design and management teams, it adheres to the business philosophy of safety, integrity and pragmatism to provide comprehensive end-to-end services for customers. Holding a number of patented technologies, SINE STAIR is an original manufacturer of special-shaped cantilevered steel staircases. It is also the only enterprise in China that has mastered the fabrication and installation technology for curved full-glass staircases. Having overcome multiple technical challenges in the industry, it skillfully combines mechanical safety with visual aesthetics.
The enterprise operates two production bases: a 6,000-square-meter base in Suzhou and a large 60,000-square-meter base in Xishui, Huanggang, Hubei, with a total production area of 66,000 square meters. It has built fully functional sections including a steel structure factory, a glass staircase R&D center and a large exhibition hall. The team has expanded from the founding couple of two people to over 300 employees. The average working experience of construction and installation team members ranges from 10 to 30 years, granting them abundant practical experience. Meanwhile, marketing and business centers have been established in Shanghai, Beijing, Shenzhen, Suzhou and Hubei. Its business covers the whole country and extends to overseas markets, with more than 5,000 completed projects across residential, commercial, corporate and public building scenarios.
Upholding the product philosophy of striving for excellence, SINE STAIR supports highly personalized customization. Customers only need to put forward their ideas. Combining the on-site architectural conditions, material characteristics and overall spatial environment, we carry out precise structural calculations and develop aesthetic creativity, enabling every staircase project to achieve both mechanical soundness and aesthetic appeal. Complete implementation solutions are available here for residential spiral staircases in villas and duplex buildings, as well as large sculptural special-shaped staircases in commercial complexes and public buildings.
Evolving from a small family workshop to an original manufacturer with a global layout, SINE STAIR builds on past achievements and unleashes accumulated strength, continuously promoting technological upgrades in China’s custom staircase industry. For more products and cases: www.sinestair.com
