Success projectsSuccess Stories from 80+ Countries
As a leading commercial greenhouse manufacturer, we have been deeply involved in the greenhouse industry for 25 years, with projects covering 80+countries across six continents including Europe, America, the Middle East, Central Asia, Southeast Asia, and Africa.
Partners
We pride ourselves on the trust and satisfaction of our clients.
The client of this project is not an individual grower, but a national-level protected agriculture demonstration project led by the Ministry of Food, Agriculture and Light Industry of Mongolia. Mongolia is an inland country featuring long, frigid winters; extreme low temperatures near Ulaanbaatar can drop to -40°C.
The Romanian client operates in the Argeș region, roughly 120 km north of Bucharest. It is a local agricultural enterprise specializing in large-scale tomato cultivation. The client supplies tomatoes to chain supermarkets and fresh produce delivery platforms serving Bucharest and neighboring towns, and has built reliable distribution channels within the domestic tomato supply chain.
The US client operates in California's Central Valley. It is a medium-scale agricultural enterprise focused on year-round production of organic leafy greens, including lettuce, kale, arugula and spinach. The client supplies fresh leafy greens to premium organic supermarkets and farmers' markets across the San Francisco Bay Area. Having served this niche market for more than a decade, it has built stable B2B client networks and solid brand credibility.
The Philippine client is located in the southern part of Luzon Island and is a medium-sized comprehensive agricultural enterprise. Previously, it mainly engaged in the cultivation of tilapia and milkfish in open-air fish ponds, with small areas of open-air vegetable fields planted with leafy vegetables to supply the local wholesale market.
