Steel stair formwork is an industrial mold system specifically designed for pouring concrete stairs. It uses a composite structure of high-strength steel plates and structural steel to provide a standardized, reusable solution for in-situ stair formation.

Core Structure:

- The main body is precisely pressed from 4-6mm Q235B high-quality steel plates
- Back reinforced with #8 channel steel frame
- Step shaping modules and side panels use a quick-connect system
- Surface treated for rust prevention (galvanized/powder-coated)

Product Advantages:

- High-precision molding: CNC processing ensures step dimension errors ≤2mm, achieving fair-faced concrete效果
- Fast formwork setup: Modular design increases installation efficiency by 60%, with single-flight stair formwork setup time ≤2 hours
- Ultra-strong load-bearing: Side pressure resistance ≥60kN/㎡, ensuring zero deformation during pouring
- Economical and durable: Normal usage can be cycled over 200 times, reducing overall cost by 50% compared to wooden formwork

Technical Features:

- Adjustable support system to accommodate different floor heights and angles
- Integrated automatic release agent spraying device
- Leak-proof sealing design with well-defined step edges
- Equipped with intelligent safety ladders, compliant with OSHA standards

Applications:

- Standard stairs in residential buildings
- Long-span stairs in public buildings
- Heavy-duty stairs in industrial plants
- Custom-shaped creative staircases
