I. Solid Foundation: Intelligent Manufacturing at Dual Bases and Independent Control Over the Entire Industrial Chain

Shanzhi Stair is affiliated with Tongrui Industrial. Since the brand was founded in 1990, it has consistently adhered to the development philosophy of "connecting the past and the future, and achieving breakthroughs through steady accumulation". It has established a complete corporate organizational structure, where the R&D Department, Technical Department, Inspection Department, Production Department, Sales Department and Customer Service Department each perform their respective duties. Professional design and engineering management teams provide full‑process support for the implementation of every project.

To achieve full‑process independent quality control, the brand has established two self‑owned standardized production bases: a 6,000‑square‑meter fine‑processing base in Suzhou for rapid customization for small‑and‑medium‑sized villas and commercial projects; and a 60,000‑square‑meter large intelligent manufacturing plant in Huanggang, Hubei, which undertakes heavy‑duty steel‑structure staircase projects with extra‑high and extra‑large‑span requirements. Equipped with a complete set of equipment for numerical‑control cutting, arc bending, welding and deep‑processing of glass, the plant produces all components in‑house to eliminate process deviations and delivery risks caused by outsourcing.

With market presence covering core cities across China, dedicated marketing‑service departments have been set up in Shanghai, Beijing, Shenzhen, Suzhou and Hubei. Its projects span more than 5,000 cities worldwide, serving diverse scenarios including high‑end private residences, star‑rated hotels, commercial landmarks and cultural‑tourism complexes. A global one‑stop service system of "design‑production‑installation" has been established. Clients only need to present their spatial concepts, and the team will conduct precise mechanical calculations and aesthetic extensions based on architectural forms and spatial environments, enabling every staircase to perfectly match the site’s character.

II. Technological Breakthrough: Possessing Exclusive Craftsmanship to Lead the Industry's Innovation Track

Innovation constitutes the core competitiveness of Shanzhi Stairs. As a professional staircase enterprise with multiple independent patented technologies, Shanzhi boasts two exclusive core industry advantages: it is the source manufacturer of special‑shaped cantilever steel‑structure staircases in China, and also the country’s sole enterprise that has fully mastered the complete set of techniques for manufacturing and installing curved all‑glass staircases. It has tackled common industry challenges including curved glass forming, load‑bearing for large‑span cantilevers, and millimetre‑level splicing calibration.

Unlike most manufacturers that only produce standard‑specification staircases, Shanzhi specializes in ultra‑high‑difficulty non‑standard artistic staircases. It excels at complex projects such as large‑span multi‑curved spiral staircases over 10 meters, column‑free suspended glass staircases, and outdoor weather‑resistant steel‑structure landscape staircases. Leveraging 3D modeling and finite‑element force‑simulation systems, its R&D team keeps component‑processing errors within a millimeter‑level tolerance. The brand delivers both visual lightness and long‑term operational safety, balances artistic styling with structural load‑bearing capacity, and truly achieves "great looks plus outstanding durability".

III. Unchanged Original Aspiration: Empowering the Aesthetics of Every Space with Exquisitely‑Crafted Staircases

Thirty‑five years of forging ahead through trials and hardships, Shanzhi Staircases has always adhered to the product philosophy of "Safety, Integrity, Pragmatism, and Constant Pursuit of Perfection". Rejecting assembly‑line homogeneous products, it focuses on creating exclusive custom‑built staircases for every client. Whether it is minimalist floating glass staircases, grand steel‑structure spiral staircases, outdoor landscape art staircases, or non‑standard special‑shaped staircases suitable for villas, hotels and exhibition halls, the brand upholds three major service standards:

1. Customized Design: One‑on‑one joint communication by designers and structural engineers to deliver exclusive solutions based on house layout, decoration style and usage requirements;

2. Independent Production: In‑house manufacturing at two‑base factories with full‑process monitoring of key procedures including welding, anti‑corrosion treatment and glass forming;

3. Standardized Implementation: In‑house professional installation teams provide nationwide on‑site services, with long‑term after‑sales maintenance available upon project completion.

From high‑end private residential properties in China to well‑known overseas commercial buildings, from urban office towers to cultural tourism resort landmarks, Sinestair has proven through thousands of completed projects that staircases are more than mere passage‑making facilities; they are works of art that elevate spatial style and embody architectural temperament. Going forward, the brand will continue to delve into technological innovation, refine product craftsmanship, and serve more designers and property owners across the globe with higher‑standard custom staircase solutions.
