Professional Evaluation Data Interpretation: PVC-Coated Canvas for Roof Tents/Truck Tarps

This product is specifically designed for mobile carrier protection, utilizing high-strength low-elongation polyester base fabric with weather-resistant PVC coating. Wind tunnel simulations demonstrate that the fabric maintains structural integrity at speeds up to 120 km/h, exhibiting strong wind resistance. With a hydrostatic pressure rating ≥6000mm, it has passed -30°C to +70°C high-low temperature cycling tests, ensuring no cracking or deformation under extreme climatic conditions. According to dynamic abrasion testing (ASTM D4966), the fabric remains intact after 50,000 friction cycles and meets UV resistance standards with a 5-year outdoor exposure strength retention rate >80% (1500-hour xenon lamp test), providing reliable protection for rooftop tents and trucks in prolonged outdoor use.

Roof Tent/Truck Tent PVC Canvas Selection Guide

1. Dynamic strength and wind resistance data
Prioritize verifying the tear resistance strength (recommended ≥ 500N) and dynamic wind load test report. High quality fabrics need to undergo wind tunnel testing at a simulated speed of ≥ 100km/h to ensure their wind resistance during high-speed driving. Ordinary canvas is prone to severe shaking and tearing under these conditions.
2. Key indicators of environmental adaptability
It is necessary to confirm the temperature resistance range (recommended -30 ℃ to+70 ℃) and UV resistance data (xenon lamp aging ≥ 1500 hours). The temperature difference of the roof environment is large and the sun exposure is strong. The materials should maintain low temperature flexibility and aging resistance to avoid embrittlement and deformation.
3. Wear resistance and waterproof performance
Verify the wear resistance frequency (recommended ≥ 50000 revolutions) and hydrostatic pressure value (≥ 6000mm). The roof tent often contacts with baggage friction and needs to cope with rainstorm. Insufficient data will lead to early wear and water seepage. Another suggestion is to choose a surface anti slip treatment model to enhance luggage stability.

Q: What is the wind resistance of this roof tent fabric during long-distance high-speed driving?
Answer: The performance is very stable. We have driven at speeds of 110-120km/h on the highway multiple times, and the tent fabric has been tightly adhered without severe shaking throughout the entire process. Its tear resistance strength (≥ 500N) and reinforcement design effectively resist strong wind pressure, and the structural integrity remains intact.
Q: Is the material prone to aging or deformation under extreme temperature differences outdoors?
Answer: Excellent durability. After experiencing a complete annual cycle from -20 ℃ winter to 40 ℃ summer, the tent fabric did not show significant hardening, softening, or deformation. Its UV resistance performance (tested by a 1500 hour xenon lamp) ensures that the fabric does not turn yellow, and the estimated tensile strength retention rate is still above 85%.
Q: Can waterproof and wear-resistant performance cope with complex outdoor environments?
Answer: Absolutely possible. Encountered heavy rain during multiple outdoor camping trips, the static water pressure value of the tent remained ≥ 6000mm, and the interior was completely dry. The daily friction between the surface, branches, and equipment did not cause significant wear, and its wear resistance test exceeding 50000 times has been verified in practice.
