As a pioneer in construction formwork innovation, Shaanxi Flourish Industrial Co., Ltd. introduces Aluminum Stair Formwork-engineered exclusively for staircase construction, solving pain points like uneven steps, complex assembly, and short service life that plague traditional stair formworks. It's your trusted partner for building safe, precise, and efficient staircases.
Product Advantages
1. Stair-Specific Precision：Integrated step and riser molding design ensures step height error ≤1mm and riser straightness error ≤0.5mm-meeting high-end architectural standards. Unlike floor formwork, it has built-in step edge protectors to prevent concrete chipping during demolding, keeping stair edges neat.
2. Stairwell-Suited Efficiency：Optimized for narrow stairwell spaces, the modular components (max single-piece width 400mm) can be assembled in tight areas without heavy equipment. A 2-flight residential staircase (12 steps) takes only 1.5 days to install-60% faster than wooden stair formwork.
3. All-Weather Durability：6061-T6 aluminum alloy with anti-corrosion coating resists rust in outdoor stair projects (e.g., building entrance stairs, outdoor fire escapes) and maintains stability in temperature fluctuations (-15℃ to 50℃), with no deformation after long-term use.
4. Design Flexibility for Stairs：Supports customizations for step depth (250mm-320mm), riser height (150mm-180mm), and stair angles (30°-45°). It's the only solution for complex stair types like L-shaped, U-shaped, and double-spiral stairs in luxury hotels or museums.
5. Stair-Centric Cost Savings：Reusable 300+ times, it reduces formwork replacement costs by 70% vs. disposable wooden formwork. The precise molding eliminates step leveling work, cutting post-construction labor by 40%-critical for high-volume residential projects.
Products Description
1. Material & Performance：6061-T6 aluminum alloy (density 2.7g/cm³, yield strength 200N/mm²); anti-corrosion coating thickness 8-10μm; service life ≥8 years under normal use.
2. Core Stair Components：
Step Panels: 4mm-thick aluminum, with 5mm anti-slip ribs (prevents concrete sliding during pouring).
Riser Panels: 3mm-thick aluminum, pre-drilled for easy height adjustment (10mm increments).
Stair Supports: Telescopic steel poles (adjustable length 1.2m-2.5m) with anti-tip bases (load capacity 8kN/pole).
3. Standard Stair Kits：
Residential Kit: Fits 10-15 steps (step depth 280mm, riser height 160mm); weight 85kg/kit.
Commercial Kit: Fits 12-18 steps (step depth 300mm, riser height 150mm); weight 110kg/kit.
Installation Process
1. Pre-Installation：Mark step/riser positions on the wall; ensure stairwell floors are level (error ≤2mm).
2. Assembly：First install the riser panels, fix with steel supports, then attach step panels-lock with quick-release clips (no tools needed).
3. Pouring：Pour concrete from top to bottom; use a small vibrator (diameter 30mm) to fill step corners.
4. Demolding：Remove clips first, then riser panels (wait 24h), finally step panels (wait 48h)-avoid prying step edges
FAQ
1. Can it handle curved stairs with varying step depths?
：Yes-we provide custom curved panels (radius ≥1.5m) and adjustable step depth inserts.
2. How to adjust for different floor heights?
：Telescopic supports and 10mm-increment riser panels accommodate floor height differences (0-100mm).
3. Is training needed for installation?
：No-our kit includes a step-by-step video guide; 2 workers can master it in 1 hour.
