Product Advantages:

Feature Plastic Arch Formwork Wood Formwork Steel Formwork
Material High-strength composite, waterproof, corrosion-resistant, stable in extreme temps Solid wood, easy to crack/rot, high water absorption Heavy steel, prone to rust, poor corrosion resistance
Construction Lightweight, no heavy machinery, interlocking design (no leakage), quick arch assembly Needs on-site cutting, joints leak easily, poor arch adaptability Extremely heavy, needs lifting equipment, hard to shape arches
Modularity Full accessories, freely splicable to any arch radius (R125/R150/R300cm)Customizable Fixed size, no standard parts, cannot adjust arch radius Standard panels, heavy, limited flexibility for curved shapes
Lifespan Reusable 100+times, 5-8 year lifespan, low maintenance Reusable 8-15 times, 1-2 year lifespan, high waste Reusable 30-50 times, 3-5 year lifespan, high rust/maintenance cost
Cost Moderate upfront cost, long-term cost-effective Low upfront cost, high labor/waste cost High upfront cost, high transport/labor cost
Eco-Friendly 100% recyclable, no construction waste 100% recyclable, no construction waste Recyclable but high production energy cost

Application Scenario:
  • Transportation Engineering: Highway embankments, railway slopes, tunnel entrances, and bridge approach protection. Specialized for casting concrete arch skeletons to stabilize soil and prevent landslides.

  • Municipal Infrastructure: Urban drainage ditch slopes, flood control embankments, and sidewalk retaining walls. Adapts to complex arch structures for long-term outdoor durability.

  • Water Conservancy Projects: Canal slopes, reservoir embankments, and waterway revetments. Waterproof and corrosion-resistant, ideal for humid and water-immersed environments.

  • Landscape & Garden: Landscape arch retaining walls, garden walkway borders, and park slope decoration. Smooth finished surfaces with a neat, natural look.

Using Effect:
  • Precise Arch Forming: Specialized interlocking design ensures accurate arch radius and shape, no slurry leakage or mold expansion, achieving perfect slope protection structures.

  • High Construction Efficiency: Lightweight design for easy manual handling. Splicing is 30% faster than steel formwork, reducing labor costs and shortening project duration for slope projects.

  • Long-Term Cost Savings: Reusable 50-100 times, with normal maintenance. The single-use cost is only 60% of steel, significantly reducing material waste and overall project expenses.

  • Stable Slope Stability: High-strength engineering plastic material provides strong anti-deformation ability, ensuring the concrete arch skeleton has excellent load-bearing capacity and long-term slope stability.

  • Eco-Friendly & Low Maintenance: 100% recyclable, no toxic materials. Requires minimal upkeep and complies with green construction standards for infrastructure projects.
