Choosing the wrong greenhouse covering material may cause uneven light transmission, large temperature fluctuations inside the greenhouse, and frequent replacement of materials. This article compares polycarbonate hollow sheet, PVC sheet and PE film to help greenhouse projects choose the most suitable roofing material.

Yes, delivery to a designated warehouse in China can be arranged without any issues. GWX supports flexible shipping solutions to meet different logistics requirements, including direct delivery to domestic warehouses, distribution centers, or specified storage locations.

Yes, installation guidance for solid polycarbonate sheets is available. GWX provides basic installation instructions with visual diagrams that demonstrate standard installation methods and key construction principles.

Standard solid polycarbonate sheets have a surface hardness of approximately 2B, which means the material is inherently susceptible to surface scratches under mechanical contact or abrasive conditions. Like most transparent thermoplastic materials, surface abrasion may occur during installation, cleaning, or long-term use in exposed environments.

GWX polycarbonate sheets can be produced using different raw material options based on customer requirements and project specifications. We offer flexible material sourcing and support both premium-grade and cost-optimized solutions to meet diverse application needs.

The hail resistance performance of solid polycarbonate sheets depends on multiple factors, including sheet thickness, hailstone diameter, impact height or velocity, as well as material formulation and service conditions. Based on ASTM impact testing standards, thicker sheets generally provide higher impact resistance and better protection against severe hail events.

For projects located in areas with strong wind loads or hurricane exposure, GWX generally recommends using corrugated polycarbonate sheets with a thickness of at least 1.5mm. Thicker sheets typically provide better rigidity, impact resistance, and overall structural stability under extreme weather conditions.

Under normal installation and usage conditions, GWX polycarbonate sheets are designed to provide a service life of approximately 10 years. The actual lifespan may vary depending on factors such as climate conditions, UV exposure intensity, installation quality, structural design, and daily maintenance.

Learn how to choose polycarbonate sheets for hot, rainy, cold, snowy and windy climates. Compare UV protection, drainage, insulation, U-values and wind-load considerations for roofing, greenhouse and canopy projects.

Under proper installation conditions, polycarbonate sheets are designed to provide reliable waterproof performance and should not leak. In most cases, water leakage is not caused by the sheet material itself, but rather by installation quality, structural design, or improper sealing treatment during construction.

Like most polymer-based materials exposed to long-term outdoor conditions, polycarbonate sheets may experience a certain degree of yellowing over time. This is a natural aging phenomenon caused by factors such as ultraviolet exposure, weather conditions, temperature variation, and environmental pollutants. Even high-quality white or transparent materials can gradually develop slight discoloration after years of use.

Yes. GWX sheets are manufactured with UV protection to improve long-term outdoor performance and durability. The UV component is not simply applied afterward; it is incorporated directly into the raw material formulation during production, helping enhance the sheet’s resistance to sunlight exposure and environmental aging.
