Product Description

Sainpoly Gothic Greenhouse: Lightweight, Efficient, Economical, and Durable

The combination of hot-dip galvanized light steel structure and high-strength anti-aging agricultural film ensures the bearing capacity while realizing the structural lightweight. The arched streamlined apex design combines snow removal and wind resistance performance: the steep slope accelerates the sliding of snow, the streamlined surface reduces wind resistance, and the structure is simple but has excellent load-bearing capacity. The service life of domestically produced new agricultural film is extended by 2-4 years compared to ordinary film, significantly reducing the frequency of replacement and maintenance costs.

Widely adaptable to diverse planting scenarios such as vegetable, fruit, seedling cultivation, and hydroponics, the environmental control system (heating, cooling, etc.) can be flexibly selected according to climate conditions to construct a suitable growth environment as needed.

Provide a one-stop service for the entire process from scheme design, production and manufacturing, on-site installation to after-sales use, making customers worry free and effortless.

Application and Solutions

Extremely cold in winter，conventional greenhouse vegetable crops will experience irreversible freezing damage.

Efficient Cold Insulation

Under -25 ℃ in winter, vegetables are prone to freezing to death.

Fully utilizing the ample internal space of the Gothic spire structure, a double-layer inflatable film cover (forming an air insulation layer), internal insulation curtains, and reserved heating interfaces are configured. The double-layer film structure can effectively block the conduction of outdoor cold air to the indoor environment, and the insulation performance is improved by more than 30% compared to single-layer film, ensuring the safe overwintering of crops.

Snow-resistant Structure

Risk of Snow Collapse

Gothic spires or steep arched roofs themselves have good snow sliding performance. On this basis, a complete anti snow bearing system is formed by combining reinforced trusses, enlarged main skeletons, and high-strength bolted connections. The design value of snow load covers 0.2-0.8kN/m2, and can be customized and selected according to the meteorological conditions of the project location to ensure structural safety.

High Light Transmittance

Short light exposure time leads to slow vegetable growth

The cover layer of Goth Greenhouse is made of high light transmittance, anti-aging and drip proof film, with a light transmittance of 90%, which can collect natural light to the maximum extent. At the same time, an LED plant supplementary lighting system can be optionally selected to extend the daily effective light duration to 14 hours, effectively ensuring that crops maintain normal growth rates during low light seasons.

High Energy Costs

The double-layer inflatable film structure significantly improves the insulation performance of the enclosure structure through an air layer, and the continuous operation of the air pump ensures the stability of the insulation layer. By cooperating with the zone control system, fine management of the heating area can be achieved, which can reduce winter heating energy consumption by more than 30% compared to single-layer film greenhouses, significantly saving operating costs.

Long-lasting Frame

The traditional greenhouse has a short service life, full hot dip galvanized steel frame+high-quality film. The structural service life is more than 15 years, the thickness of the galvanized layer is ≥ 65 µ m, and the anti-corrosion performance is excellent. The main structure has a 10-year warranty. The film is imported anti-aging and anti dripping film, with a service life of 3 to 5 years, easy replacement, and low maintenance cost.

FAQ

Q: Can the span and bay of the Gothic greenhouse be customized?

A:The standard configuration offers spans of 8m/9.6m and a bay of 4m. Customization of various spans and bay lengths is available to suit different site requirements.

Q: What crops are suitable for cultivation in Gothic greenhouses?

A: Gothic greenhouses support a wide range of crops, including vegetables, flowers, and seedlings. They are especially ideal for tall crops such as tomatoes and cucumbers, as well as off-season cultivation of strawberries and leafy greens.

Q: Do you provide installation services? Is remote guidance feasible?

A: We offer two installation support options: ① Send technicians from the headquarters for on-site guidance; ② Provide detailed installation videos and manuals, with full remote assistance, and installation can be completed smoothly even for beginners.

Q: How is the wind and snow resistance of Gothic greenhouses compared to traditional greenhouses?

A: The pointed arch design naturally sheds snow. With standard 0.32KN/m² snow load and 0.27KN/m² wind load configurations, the upgraded version can withstand loads up to 0.8KN/m², offering superior wind and snow resistance.

Q: What is the minimum order area for the Gothic greenhouse?

A: There is no mandatory minimum order area, but we recommend orders of 3,000 m² or more to spread design and transportation costs. Sample projects are negotiable.

Q: Do your Gothic greenhouses for vegetable cultivation comply with EU standards?

A: Yes. Our greenhouses hold CE certification. All components, including steel structures, covering films, and sealants, meet relevant EU standards, and we can assist customers with local acceptance inspections.
