Fine Aggregate Concrete Permanent-Form Floor Deck: A New-Generation Efficient & Eco-Friendly Prefabricated Floor Solution
Fine Aggregate Concrete Permanent-Form Floor Deck (also known as Steel-Bar Truss Permanent Formwork Deck) is a 4th-generation high-efficiency floor system developed for the trend of building industrialization and prefabricated construction. It integrates steel-bar trusses with a high-strength fine aggregate concrete base in a factory. Acting as a permanent formwork during construction, it remains in place and composes a monolithic structural floor with cast-in-situ concrete.
Product Advantages：
✅ Ultra-Fast Construction
No formwork erection or stripping, supports-free for spans ≤2.5m. Construction period reduced by 30–50%, labor costs cut drastically.
✅ Structural Integrity
Truss and concrete base act compositely, offering high rigidity and excellent seismic resistance. Minimum total floor thickness 100mm .
✅ Cost-Effective
Lightweight (60–80kg/㎡) , transport efficiency 3x higher; overall cost 20%+ lower than traditional precast slabs.
✅ Superior Quality
Factory automated production ensures precise steel placement and dense concrete. Smooth soffit ready for direct finishing .
✅ Green & Low-Carbon
100% timber-free , minimal waste and wet works, low noise.
✅ Flexible Adaptability
Standard width 1200mm, length 1–7.2m custom-made. Easily cut & cored, ideal for irregular layouts and MEP passages .
Applications：
- High-rise & mid-rise apartments, public housing
- Offices, hotels, malls, schools, hospitals
- Factories, warehouses, data centers
- Steel structures, renovation, mezzanine additions
- Projects demanding speed, cost efficiency & sustainability
With five core values: Speed, Economy, Quality, Greenness, Stability, this product eliminates the pain points of traditional floors: complexity, high cost, pollution and long duration. It is the ideal floor system for modern prefabricated construction, enabling efficient, low-carbon, high-quality industrialized building.
