Sainpoly Automatic Multi-Span PC Greenhouse Steel Pipe Frame
The Sainpoly Automatic Multi-Span PC Greenhouse Steel Pipe Frame is a modular, multi-span greenhouse built on a sturdy galvanized steel pipe frame with twin‑wall polycarbonate (PC) panels and automatic venting/openers for easier climate control. Its heavy‑duty steel frame and multi‑span design offer commercial‑grade strength, wide unobstructed growing space, and excellent wind/snow resistance. Twin‑wall PC panels provide high light transmission, UV protection and insulation, while the modular construction, straightforward assembly and low maintenance make it scalable and user‑friendly for hobbyists and commercial growers alike.
Secure Packaging, Easy Assembly
The Multi span Polycarbonate greenhouse delivers year‑round, high‑yield growing with durable 6/8/10mm PC panels, a galvanized Q235 steel pipe frame, Venlo or arched roof options, and a 10‑year material warranty to maximize light transmission and heat retention. Factory-direct production and safe export packing ensure consistent quality, customizable spans and bay widths, and proven wind/snow resistance to protect your crops and investment. Professional after‑sales engineers provide planning, installation guidance and integrated systems (ventilation, cooling, heating, irrigation, shading) for fast setup and reliable operation.
Automated Multi-Span Polycarbonate Frame
The Sainpoly Automatic Multi-Span PC Greenhouse Steel Pipe Frame is a Multi span Polycarbonate greenhouse that pairs galvanized Q235 steel pipe framing with 6/8/10mm polycarbonate panels in venlo or arched roof configurations, available in single span widths of 9.6, 10.8 and 12m with 4m bay spacing and 4.5–8m heights for scalable multi-span layouts. Its core attributes deliver high light transmission, thermal insulation and impact resistance with a service life over 15 years (10-year PC warranty), plus performance ratings such as wind resistance up to 120 km/h, snow load 30–55 kg/m², rain capacity 140 mm/h and crop load 15–30 kg/m². Designed for commercial and research use, the system combines automated climate control, irrigation, shading and ventilation options, factory-made modular components, customizable accessories (cooling pads, fans, boilers, drip irrigation) and global after-sales support to maximize yield, durability and operational efficiency.
