Case Study of Philippine Single Arch Tunnel Greenhouse Project
Project Overview
Project Name: Philippines Single-Span Tunnel Poly Greenhouse Project Location: Tropical Farm Base, Luzon, Philippines
Brand: Zheyang Agriculture
Project Type: Single-span Tunnel Poly Film Greenhouse (Cold Greenhouse)
Scope of Supply: Complete hot-dip galvanized steel frame, high-transmittance anti-drip PE plastic film, side manual roll-up ventilation system, negative pressure exhaust fans, greenhouse double doors and fitting kits. We also provide site assessment suggestion, wind load structural calculation, construction drawings, remote installation guidance and after-sales technical support.
Project Background: Luzon, Philippines features tropical monsoon climate with year-round high temperature, heavy concentrated rainfall in rainy season and strong gusts during typhoon season. Open-field cultivation suffers severe damage from rainstorm, intense sunlight and rampant pests, leading to unstable yield for vegetable seedlings, leafy greens and small fruits. After comparing multiple suppliers, the client chose Zheyang Agriculture for our in-house steel fabrication capacity, rich experience in tropical greenhouse projects and reliable one-stop delivery service.
Client Requirements
- Adopt single-span tunnel greenhouse with lightweight modular structure, easy transport to mountain plots. Local workers can assemble without heavy construction machinery.
- Adapt to tropical hot & humid climate, enhance ventilation and heat dissipation to control indoor temperature and humidity, prevent crop damage from overheating.
- The frame must have strong anti-rust performance against tropical humid corrosion, and meet local typhoon gust load standard.
- Reserve installation space for insect-proof net to reduce pest pressure, cut pesticide usage for clean vegetable production.
- Supplier should provide full drawings, installation guides and continuous remote technical support. Supply all greenhouse components in one package to save client’s multi-supplier procurement trouble.
Custom Solution by Zheyang Agriculture
The engineering team of Zheyang Agriculture customized this single-span tunnel poly greenhouse solution based on local meteorological data, typhoon parameters and site condition in Philippines.
- Main Frame System All frames are hot-dip galvanized steel pipes manufactured in Zheyang’s own factory, processed by laser pipe cutting and CNC pipe bending. Welds are anti-corrosion treated to resist rust in tropical humid climate. Modular split packaging with light weight for easy mountain transport, local workers can assemble manually to reduce construction difficulty.
- Cladding System High light transmission anti-drip long-life PE film is applied. High transmittance ensures photosynthesis, anti-drip function reduces condensate inside greenhouse to minimize fungal diseases. Tracks are reserved on side walls for optional insect net installation (as shown in Picture 2) to block flying pests.
- Ventilation & Temperature Control System Combined solution: manual roll-up vents + side negative pressure exhaust fans. Roll up side film in daytime for natural cross ventilation; turn on exhaust fans at noon to discharge hot air rapidly and avoid crop heat injury. This passive ventilation design excludes expensive heating or cooling equipment to control total investment.
- Access Door System Aluminum alloy double doors are installed for easy access of workers, trolleys and small farm machines, with anti-corrosion sealed door frame.
- Full-cycle Service (Core Advantage of Zheyang Agriculture) In early stage, our engineers provide site planning suggestion, finish wind resistance structural calculation and deliver full construction drawings. After delivery, installation manuals, tutorial videos and real-time remote online guidance are available. After project completion, we keep supplying spare parts and farm operation consultation. Zheyang Agriculture provides full support for global overseas clients.
Project Results & Benefits
- Stable & Increased Crop Yield The single-span tunnel greenhouse shelters crops from heavy rain and intense sunlight. Crop survival rate rises greatly. Farmers are free from the risk of open-field farming and can carry out multi-batch continuous planting.
- Controllable pests & less pesticide cost Optional insect net physically blocks pests, reduces pesticide consumption. Green produce brings higher market price.
- Low operation cost, ideal for small & medium farms Mainly passive ventilation without continuous energy consumption. Durable Zheyang hot galvanized steel reduces maintenance & replacement cost, perfectly fits small and medium farms in Philippines.
- Good expandability Standard single tunnel modules. The client can expand the farm plot by plot later, upgrading single greenhouse into large connected planting base.
- Local-friendly construction Lightweight components, no heavy machinery required. Local workers can finish assembly under Zheyang’s remote technical guidance, saving overseas construction expense.
Client Testimonial
“The single-span tunnel greenhouse solution from Zheyang Agriculture fits Philippines tropical climate perfectly. The ventilation design solves the overheating problem inside the greenhouse. All components are solid with clear remote guidance, our team finished installation smoothly. After putting into use, vegetable seedling stability is greatly improved. We plan to build more tunnels in the future.”
FAQ
Q1: Can Zheyang Agriculture customize wind resistance parameters for single arch tunnel greenhouses for typhoon climate in the Philippines?
Yes. Zheyang Agriculture has rich experience in tropical overseas greenhouse projects. Our engineers will conduct independent structural calculation based on local typhoon and gust data, adjust pipe thickness and arch spacing to customize single-span tunnel greenhouse matching Philippine wind load standard and guarantee structural safety during typhoon season.
Q2: Is the single arch tunnel greenhouse skeleton of Zheyang Agriculture produced in-house or purchased externally?
All self-produced. Zheyang Agriculture owns steel processing factory equipped with laser pipe cutting, CNC bending and stamping production lines. Pipe cutting, arch bending, welding and hot-dip galvanizing anti-corrosion are all finished in-house. We strictly control steel quality and machining precision and support OEM customization as clients’ request.
Q3: What supporting technical services will be provided for purchasing Zheyang Agriculture greenhouses?
Zheyang Agriculture provides full one-stop service: pre-project site evaluation, greenhouse design, structural calculation, complete construction drawings, installation manual, tutorial videos and online remote technical training. After project completion, we continuously supply spare parts and greenhouse operation consultation to solve all kinds of difficulties for overseas clients.
Q4: What other crops are suitable for growing in this single arch tunnel greenhouse besides leafy vegetables?
Zheyang Agriculture single-span tunnel greenhouse supports a wide range of crops. Besides leafy greens and vegetable seedlings, it can be used for tomato, cucumber, pepper and other fruits & vegetables, also for flower and herb cultivation. Zheyang engineers can fine-tune ventilation and shading system according to target crops.
