FAQ

What is the Sainpoly Turnkey Multi-Span Film Commercial Greenhouse Frame and what does "turnkey" mean in this context?

The Sainpoly Turnkey Multi-Span Film Commercial Greenhouse Frame is a modular, galvanized-steel greenhouse structure designed to be covered with horticultural film and extended longitudinally by repeating spans. "Turnkey" means Sainpoly provides an end-to-end service: site assessment and design, supply of the frame and recommended covering, optional climate and irrigation systems, delivery, professional installation, commissioning, and basic operator training so the greenhouse is ready for commercial use.

What types of crops and production systems is this greenhouse best suited for?

It is ideal for commercial-scale vegetable crops (tomato, cucumber, pepper, lettuce), cut flowers, nursery and propagation, herbs, and protected cultivation systems such as soil-grown, substrate, or hydroponic/hanging systems. The multi-span layout supports long production rows, mechanization, trolley systems, and continuous irrigation/ fertigation lines for high-efficiency commercial production.

How flexible is the frame in size and layout — what spans, bay lengths, and heights are available?

The multi-span design is highly customizable. Typical projects use common span widths and bay lengths tailored to crop and site needs (Sainpoly will specify exact dimensions during design). The structure can be repeated to create virtually unlimited greenhouse length, and ridge height, eave height and bay spacing are adjusted to suit crop height, ventilation requirements and equipment access. Sainpoly engineers size components to meet the chosen dimensions and local load requirements.

What climate control and ventilation options can be used in this greenhouse?

Multi-span film greenhouses support a range of climate-control strategies: natural ventilation (ridge, sidewall and end-wall vents), mechanical ventilation using fans, evaporative cooling pads for hot climates, heating systems for winter production, shading nets or screens for light control, and automated controllers integrating temperature, humidity, CO2 and irrigation. Sainpoly can recommend and supply combinations of these systems based on crop, local climate and production goals.

What film coverings are recommended and how durable are they? What maintenance is required?

Common coverings include UV-stabilized polyethylene (single or double-layer for inflated insulation), anti-drip/anti-condensate films, and specialized light-diffusing or reinforced films. Lifespan typically ranges from about 3 to 6 years depending on film type, climate exposure and maintenance; double-layer plastic with inflation can extend seasonal performance. Regular maintenance includes keeping film tensioned, repairing punctures quickly, cleaning to maintain light transmission, and replacing films on a planned schedule to preserve crop performance.

How does the frame perform against wind and snow, and what site/preparatory steps are needed before installation?

The frame is engineered to meet specified wind and snow loads for the project location. Typical preparatory steps: a site assessment and soil investigation, grading and drainage preparation, selection of appropriate anchoring (concrete footings, anchor bolts or screw piles), and obtaining local permits. Sainpoly designs foundations and bracing to local codes and recommends appropriate reinforcements for heavy snow or high-wind zones. Proper site prep and anchoring are essential for safe, long-term performance.
