Multi span sawtooth greenhouse

Multi span Sawtooth Greenhouse is a large-scale, modular greenhouse structure characterized by its distinctive sawtooth roof design—a series of alternating peaked and valleyed roof sections that resemble the teeth of a saw. This design maximizes natural light penetration while optimizing ventilation and structural stability. Widely used in commercial horticulture, research facilities, and botanical gardens, multi-span sawtooth greenhouses are ideal for year-round cultivation of high-value crops (e.g., tomatoes, cucumbers, flowers) in regions with moderate to high sunlight exposure.

Frame

The Frame Materials of greenhouse are hot dip galvanized steel and accessories.The structure is strong and durable.

The warranty period of frame is 15~20 years

Covering

PO film cover

Thickness: 120/150/200 microns.

UV-Resistant Film: Temporary or cost-effective option for short-term setups.

Natural Ventilation:

Vents along the north-facing roof slopes (peaks) and sidewalls for cross-ventilation; hot air rises and exits through peak vents (stack effect).
Motorized louvers or automated vents for temperature regulation.

Anti-insect net

The Anti Insect Net is made by 100% virgin HDPE with stable UV. It provides protection from range of insects that can be harmful. This preventive method reduces the cost of pesticides to grow organic and natural cultivation.

Wide Application

Wide application of sawtooth roof greenhouse

Commercial Horticulture

Large-scale production of tomatoes, cucumbers, and peppers in regions with consistent sunlight (e.g., Mediterranean climates).
Flower cultivation (e.g., roses, lilies) requiring balanced light and temperature.

Research & Botanical Gardens

Controlled environments for plant breeding or climate change studies.
Display of diverse plant collections (e.g., tropical vs. temperate species) in separate spans.
