Multispan Sawtooth Plastic Greenhouse

SHG Multispan Sawtooth Plastic Greenhouse is a commercial multi-bay growing facility that stands out with its exclusive sawtooth roof vertical ventilation design. We construct the whole framework with full hot-dip galvanized steel and cover it with anti-UV plastic film.

Thanks to the chimney-style natural convection principle, this greenhouse exhausts excess heat and humidity far more efficiently. As a result, growers can drastically cut down daily cooling power expenses during hot seasons.

Moreover, its modular splicing structure supports unlimited continuous large-area planting. It also works perfectly with a full lineup of auxiliary systems, such as internal & external shading nets, pad-fan cooling units, seedling benches and automated irrigation equipment.

We have exported this greenhouse widely to commercial farms across Australia, the US, and tropical & subtropical regions in Africa. It fits perfectly for high-temperature zones that demand stable low-temperature growing environments for crops.

In addition, we pre-cut and pre-drill all steel structural components in our factory. Every complete set comes with bilingual Chinese-English assembly drawings and full export clearance documents to simplify overseas project delivery.

Product Description

Core Specifications & Parameters

This sawtooth multi-span plastic greenhouse combines independent motorized vertical rolling roof vents and side roll-up vents. With this dual ventilation layout, it achieves full-range air circulation inside the greenhouse.

Furthermore, all structural parts receive full high-temperature hot-dip galvanizing treatment. This robust anti-rust finish lets the frame withstand coastal salt fog erosion and long-term intense ultraviolet radiation.

To match diverse local climate conditions and crop cultivation requirements, we fully customize core dimensions including span width, eave height, column spacing and vent opening size for each project.

Core Advantages

Cost-Effective, Durable and Scalable Greenhouse Solution

Powerful natural cooling performance

The unique sawtooth roof vertical vents generate strong upward air flow. In hot summer, it can lower internal temperature by 6–9℃ effectively, which greatly reduces electricity costs for cooling facilities.

Long-lasting anti-corrosion steel framework

We hot-dip galvanize all steel components thoroughly. Therefore, the structure delivers reliable rust resistance for inland high-UV areas and coastal salt fog planting zones.

Spacious continuous growing area with full automation compatibility

Its multi-span layout creates large unobstructed planting space. Meanwhile, it supports matching all mainstream greenhouse automatic control auxiliary systems to realize intelligent farming.

Fast on-site installation to save labor expenditure

All structural parts are prefabricated in our workshop with precise positioning holes. As a result, field workers finish assembly much faster and cut overall labor investment.

High flexible customization for global climate zones

We adjust span width, eave height and ventilation area freely. In this way, the greenhouse adapts to tropical, subtropical and temperate agricultural regions worldwide.

Applications

Applicable Scenarios

Commercial Planting Application Scenarios

Commercial seedling nurseries: Leafy greens, flowering plants, succulent propagation

Tropical & subtropical fruit and vegetable commercial cultivation

Large-scale professional nursery bases and agricultural industrial parks

Matched Global Overseas Projects

We deliver this sawtooth greenhouse to growing bases in Australia, the USA, Kenya, Zimbabwe and more agricultural regions.

Standards & Compliance

We produce all frame steel pipes in line with AS/NZS Australian agricultural steel standards, and test zinc coating thickness strictly before factory shipment.
Our anti-UV plastic film undergoes complete aging resistance and anti-drip testing; we attach official third-party inspection reports to every batch.
Our structural design passes wind load and snow load simulation tests, fully meeting international greenhouse engineering norms.
The factory holds ISO9001 quality management certification, and we provide full sets of English export papers for US and Australia customs clearance.
We supply bilingual Chinese & English technical drawings permanently, and maintain long-term spare parts matching service for post-project maintenance.
