Steel stair formwork is a concrete forming system designed and manufactured using the concept of Industry 4.0, which is designed for modern building construction to provide high-precision and efficient stair pouring solutions. The products are based on high-strength special steel, and realize the standardized and modular production of stair structures through digital simulation design and intelligent processing technology.

Technical parameter system
Main specifications: The core plate is made of 6mm thick Q355B high-strength steel, with an ultimate tensile strength of 490-620MPa; The reinforced frame is made of 12# heavy-duty channel steel, which is heat-treated to eliminate internal stress.
Precision control: step forming tolerance ≤± 1.0mm, surface roughness Ra≤3.2μm, which can directly reach the standard of decorative concrete.
Load capacity: lateral compressive strength ≥ 100kN/㎡, and the system stability meets the requirements of C50 concrete high-speed pouring.
Durability performance: triple anti-corrosion treatment (hot-dip galvanization, epoxy primer, fluorocarbon topcoat), salt spray resistance test for more than 3000 hours.

Core technical advantages
Breakthrough in construction efficiency: The intelligent quick installation system realizes the completion of the formwork in 30 minutes for a single running staircase (15 levels), saving 75% of man-hours compared with the traditional process.
Molding quality assurance: The stepper module manufactured by the five-axis linkage CNC machining center ensures that the dimensional accuracy meets the military-grade standard.
Outstanding economic benefits: the design is recycled more than 500 times, and the full-cycle cost is only 12% of that of wooden formwork and 40% of aluminum formwork.
Safety intelligent upgrade: Built-in distributed sensor network to monitor stress, displacement, and temperature changes in real time, with an early warning accuracy of 98%.

Technological innovation characteristics
Adaptive slope system: The hydraulic adjustment device supports continuous slope change from 10° to 60° to meet special building design needs

Intelligent temperature control technology: built-in heating unit to ensure the quality of concrete curing in winter construction

Non-destructive release system: pneumatic jacking roller guide design, the damage rate of the formwork is reduced to less than 0.5%

Digital twin interface: supports seamless docking with BIM 5D management system to realize digital management of the whole construction process
