I. Technical Features
1. Material & Manufacturing
- Material Properties: 304/316L stainless steel (316L contains 2–3% molybdenum for superior chloride resistance in coastal/saline environments).
- Surface Treatment: Brushed, sandblasted, or PVD-coated (e.g., titanium) finishes enhance anti-slip performance (friction coefficient ≥0.6) and aesthetics while preventing fading.
2. Structural Design
- Modular Assembly: Circular, square, or cross-shaped components adapt to tree pits of varying sizes (e.g., 1m×1m or irregular shapes), with pre-cut holes for landscape lighting.
- Water Management: Open area ratio ≥80% stores rainwater for root absorption while directing runoff to reduce soil erosion.
- Anti-Slip & Load-Bearing: Diamond treads or linear grooves ensure load capacity ≥1 ton per unit, compliant with EN124 standards (uniform load ≥3.0 kN/m² for pedestrian zones; ≥7.5 kN/m² for high-traffic areas).
II. Core Advantages
1. Corrosion Resistance & Longevity
- 316L resists acids, salts (pH 1–14), and salt spray (ASTM B117 ≥5,000 hours), with a 30+ year lifespan, outperforming cast iron/composites.
- Temperature tolerance: -50°C to +350°C, suitable for freeze-thaw or tropical climates.
2. High Strength & Safety
- Compressive strength ≥400 MPa; withstands heavy vehicles (D400-grade: 40 tons) while protecting roots from soil compaction.
- Grille gaps ≤15 mm prevent small object loss and dust accumulation.
3. Aesthetic Integration
- Custom colors (bronze, champagne gold) and textures (woodgrain thermal transfer) blend with urban landscapes.
- Flush-mounted design ensures visual harmony in modern or historic districts.
4. Easy Installation & Maintenance
- Snap-fit modular assembly requires no welding or specialized tools, cutting labor costs.
- Routine cleaning with water only; 70% lower maintenance costs vs. traditional materials.
5. Sustainability & Economy
- 100% recyclable with 60% lower carbon footprint vs. cast iron; LEED-compliant.
- High-density material (7.3 g/cm³) deters theft due to low scrap value.
III. Applications
1. Municipal Roads & Parks
- Protects street tree roots from foot traffic/vehicles (e.g., pilot installations during Hangzhou Asian Games, later optimized).
- Reduces soil exposure and dust pollution, aligning with urban air quality regulations.
2. Commercial Plazas & Premium Communities
- Custom logos or LED-lit designs enhance branding for luxury hotels and villas.
3. Harsh Environments
- Coastal Zones: Galvanized versions resist chloride corrosion.
- Industrial Areas: Acid/alkali-resistant models protect trees from chemical exposure.
IV. Standards & Certifications
- International: EN 10088-2 (stainless steel), ISO 14122-3 (anti-slip safety).
- China: CJ/T 327-2010 (drainage grates), GB/T 26941-2011 (permeable paving standards).
- Certifications: China Environmental Labeling (Ten-Ring), EU CE-CPR (Construction Products Regulation).
Summary
