Regional Differences and Selection Tips for PVC Tarpaulin Purchasing

The selection of PVC tarpaulins should consider regional climate, application scenarios, and budget, as needs vary significantly across different areas. Below is a region-specific purchasing guide and practical tips.

I.Regional Impact on PVC Tarpaulin Requirements

1. Climate Adaptability

Region Type	Key Needs	Recommended Specs	Pitfalls to Avoid
Wet & Rainy Areas (e.g., Southern China, Coastal)	Mold-proof, hydrolysis-resistant, UV-resistant	PU coating (anti-mold), ≥800g/m² weight	Avoid cheap non-coated PVC (prone to mold)
Hot & Sunny Areas (e.g., Northwest, Deserts)	UV/heat resistance (≥70°C)	Double-sided UV treatment, antioxidants	Weight <600g/m² may crack/brittle
Cold & Dry Areas (e.g., Northeast, Plateaus)	Low-temperature flexibility (-30°C), wind/sand resistance	Cold-flex formula, reinforced edges	Standard PVC hardens/cracks in cold

2. Application-Specific Needs
- Industrial Storage (East/North China):
High tensile strength (≥4000N/5cm warp) + flame retardancy (e.g., B1 grade).
- Agricultural Greenhouses (Central/Southwest China):
Adjustable light transmission (30–70%) with diffused reflection to prevent crop burns.
- Temporary Events (Metro Cities):
Lightweight (500–600g/m²) + foldable for quick setup.

II. Key Purchasing Parameters
1. Base Fabric:
- Polyester Filament: Standard (prioritize ≥1000D for strength).
- Fiberglass Base: Heat-resistant but costly (for specialized industrial use).
2. PVC Coating:
- Double-Sided: Better waterproofing (essential for rainy regions).
- Thickness: 0.45–0.8mm (≥0.6mm for typhoon zones).
3. Add-Ons:
- Flame Retardancy: B1 (self-extinguishing) vs. B2 (slow-burning); B1 for strict fire codes.
- Antimicrobial Coating: Required for food/medical storage.

III. Price Ranges & Cost-Saving Tips

Grade	Weight/Thickness	Price (RMB/m²)	Best For
Budget	500g/m², 0.45mm	8–15	Short-term events
Mid-Range	800g/m², 0.6mm	16–25	Agriculture/warehousing
Premium	1200g/m², 0.8mm+	30–50+	Chemical/arctic applications

Savings Tips:
- Bulk purchases (10–20% discount for factory-direct orders).
- Buy off-season (e.g.,防汛tarps in winter).

IV. Regional Brand Recommendations
- South China: Guangzhou Jiuyi (anti-mold patents), Shenzhen Aokai (flame-retardant tarps).
- East China: Shanghai Shenda (industrial-grade), Zhejiang Mingshida (export-quality UV treatment).
- North China: Hebei Xinpeng (cold-resistant), Shandong Hongxiang (windproof reinforced).

V. Inspection Checklist
1. Seams: High-frequency welding > stitching (water drip test).
2. Colorfastness: Rub surface—poor-quality tarps fade easily.
3. Odor: Eco-friendly tarps should smell neutral (avoid phthalate-heavy products).

VI. Custom Solutions
- Typhoon Resistance: Diamond-grid reinforcement + metal grommets.
- Anti-Static: Carbon-fiber conductive layer (for chemical storage).
