The stair formwork system consists of stair soffit formwork, stair side formwork, stair tread formwork, and Locking Clamps. Its integral assembly allows seamless component combination, minimizing installation errors and gaps, thus streamlining construction and improving efficiency. Designed for one – time concrete pouring of stairs, it uses one – time forming to avoid multiple pours and potential joint weaknesses, ensuring structural integrity and a smooth finish while reducing post – construction work. Capable of integrating with wall, column, and roof formwork for holistic concrete pouring, this system, with a robust design, offers high strength. It can withstand pouring pressures, concrete weight, and dynamic loads, maintaining shape and ensuring dimensional accuracy. Ultimately, it creates stairs with precise dimensions, smooth surfaces, and sharp edges. By reducing surface treatments, it saves labor costs, making it a cost – effective and high – performance choice for construction projects.
Stair Formwork
Integral Assembly:
The stair formwork system’s integral assembly enables precise, seamless combination of all components. This reduces installation errors and gaps, forming a stable structure. Unlike traditional systems, it simplifies construction, cuts installation time, and boosts efficiency.


One Time Forming:
With one – time forming, the system pours the entire staircase in a single operation, eliminating multiple pours and weak joints. This ensures structural integrity, improves load – bearing capacity, and creates a smooth finish, reducing post – construction work.
Good molding effect:
The system produces stairs with precise dimensions, smooth surfaces, and sharp edges. Tight – fitting assembly and well – designed components ensure concrete shapes match specifications, reducing surface treatment needs and saving time and costs.

Efficient, Faster,Safer.
High Strength:
Engineered with a robust design, the system withstands concrete pouring pressure, wet concrete weight, and construction loads. Its components resist deformation, maintaining formwork shape and ensuring staircase dimensional accuracy while providing a safe work environment.
On-Site Display:
This stair formwork system is widely applicable to various types of buildings. In residential buildings, whether multi – storey residential buildings or high – rise apartments, its integral assembly and one – time forming features enable efficient construction of stairs in all types of housing units. For commercial buildings such as shopping malls and office buildings, it meets the requirements for aesthetics and functionality with excellent molding effects and high strength, ensuring safety and durability. In public buildings like schools, hospitals, and stadiums, relying on one – time forming and efficient assembly design, it enhances the strength and stability of stairs, ensuring timely completion of projects. In industrial buildings such as factories and warehouses, its high – strength structure and precise dimension control meet the load – bearing requirements, guaranteeing the safe and efficient transportation of personnel and goods.
