Ruize Steel, a China manufacturer of greenhouse structures, supplies Polycarbonate Multi-Span Greenhouses for high-value flower cultivation, premium fruit and vegetable production, seedling growing and agricultural research projects. Available with multiwall polycarbonate sheets, solid polycarbonate sheets and impact-resistant polycarbonate sheets, these greenhouses offer uniform light transmission, impact resistance and durability for commercial cultivation.
Dedicated Frame Design: Compatible fixing channels help improve panel fit and reduce water leakage and air infiltration.
UV and Weather Resistance: UV-protective surface treatments help slow outdoor aging and extend panel service life.
Matched Structural Support: The frame is designed to support the selected panel type and its weight, helping reduce structural deformation.
Customized Panel Specifications: Panel thickness and hollow-layer configuration can be selected according to climate and insulation requirements.
The three panel options differ in insulation, light transmission, impact resistance, service life and cost. The following table helps compare their main characteristics.
| Comparison Item | Multiwall Polycarbonate Greenhouse | Solid Polycarbonate Greenhouse | Impact-Resistant Polycarbonate Greenhouse |
|---|---|---|---|
| Panel Structure | Double-wall or multiwall hollow structure | Single-piece solid flat sheet | High-toughness modified solid polycarbonate sheet |
| Light Transmission | Even, diffused light with medium-to-high transmission | High transparency and the highest light transmission among the three options | Good light transmission with reduced glare |
| Thermal Insulation | Best of the three options; hollow air spaces reduce heat transfer | Moderate insulation without a hollow air layer | Better insulation than standard solid sheets, but generally below multiwall sheets |
| Hail and Impact Resistance | Good | Excellent | Very high toughness and resistance to cracking |
| Structural Load | Lightweight; a standard frame may be sufficient | Moderate weight; slight frame reinforcement may be required | Moderate weight, with good adaptability to curved structures |
| Typical Service Life | 8–10 years | 10–12 years | 12–15 years, with upgraded UV protection |
| Waterproofing | Effective when installed with compatible sealing profiles; slight condensation may occur | Dense solid structure with excellent water resistance | Reliable water resistance and reduced risk of cracking in low temperatures |
| Suitable Greenhouse Types | Venlo and sawtooth greenhouses with straight roof sections | Flat-roof sightseeing and research greenhouses | Round-arch, curved-roof and compatible Venlo greenhouses |
| Relative Cost | Lowest of the three options | Medium to high | Medium to high, with potential long-term value |
| Main Advantages | Good insulation, lower frame requirements and stable indoor temperatures | High transparency, impact resistance and water resistance | Temperature resistance, UV protection, curved-roof flexibility and longer service life |
Clean the Panels: Rinse the polycarbonate surfaces with clean water regularly to remove dust and maintain light transmission.
Inspect Seals and Fixings: Check sealing strips and fixing channels quarterly. Replace aged or damaged components promptly.
Avoid Sharp Impacts: Keep sharp or hard objects from striking the panels to reduce the risk of damage.
Check Connections: Inspect frame connections after periods of strong wind or heavy snow and tighten or reinforce them where necessary.
Ruize Steel has experience in PC sheet greenhouse installation and understands the thermal expansion and contraction characteristics of polycarbonate materials. Compatible frames, fixing channels and sealing components help reduce the risk of water leakage. Optional intelligent temperature control and internal or external shading systems are available for integrated project supply.
Choose multiwall sheets for insulation and cost efficiency, solid sheets for high transparency and impact resistance, or impact-resistant sheets for greater toughness, temperature variation and curved structures.
Polycarbonate panels offer better impact resistance and durability than ordinary greenhouse film, reducing the need for frequent covering replacement.
Multiwall sheets and compatible sealing profiles can help reduce dripping. In humid environments, additional ventilation, dehumidification or internal insulation may be needed.
Multiwall and standard solid flat sheets are generally used on suitable flat or gently sloping roofs. Impact-resistant sheets with sufficient flexibility are more suitable for compatible curved structures.
Yes. Span, bay width, height and panel thickness can be customized. Thicker panels and additional structural reinforcement may be specified for demanding wind, snow or hail conditions.
Frame requirements depend on panel weight and local wind and snow loads. Lightweight multiwall panels may suit standard galvanized frames, while heavier panels may require reinforced members.
UV-protected panels are designed to slow yellowing and aging. Actual durability depends on the UV coating, panel quality, climate and maintenance.
Panels can be packed separately with protective foam and wooden frames, while steel components are packed independently. Replacement arrangements for transport damage should be confirmed before shipment.
Ruize Steel supplies Polycarbonate Multi-Span Greenhouses with multiwall, solid and impact-resistant panel options for different crops, climates and greenhouse structures. Panel selection and frame specifications can be matched to insulation needs, light transmission, impact resistance and local structural requirements.
