Kevin Lyu: 30 Years of Crop Protection Netting

I am Kevin Lyu, Founder of EyouAgro

I Make the Net That Stands Between Your Crop and the Storm.

For 30 years, my team and I have manufactured crop protection netting in our own Shanghai factory — hail nets, shade cloth, insect and drape nets — and shipped it directly to growers in more than 55 countries.

The people I build for — orchard owners, vineyard managers, greenhouse growers, agricultural importers — stake a whole year on every harvest.

No trading, no outsourcing. When a failed net can cost them a season, quality has to stay on my own production lines.

Where It All Began

A Father's Factory, A Son's Purpose.

The hum of machinery was the soundtrack to my childhood, and my father, its conductor.

Wind, frost, rain, and sun nourish everything that grows, but sometimes they can also cause harm. “How can we better protect them?” I found the answer to this question in my childhood.

I often saw my father working with his beloved machines in his factory.

"This netting is a suit of armor for the plants," he told me — guarding them against the harshness of nature.

At that moment, I felt a sense of wonder and pride. Today, I have taken over my father’s business, continuing this legacy of protection. That early understanding still shapes how I evaluate netting systems — not by how they look in catalogs, but by how they perform in the field, season after season.

I am fully dedicated to advancing crop protection technology, and to working alongside every grower with more advanced, eco-friendly solutions.

We firmly believe that by protecting every crop, we are ultimately safeguarding the hard work of growers and contributing to a more abundant, quality future for the world.

Our Philosophy

More Than Protection, It's Precision Growth Control

A net is not a cover. Done right, it is a growth instrument — optical and material science working for the crop underneath.

By precisely regulating shade and ventilation, we build a comprehensive crop protection system. It actively defends against harsh conditions like hail and high winds, ensuring a stable environment for optimal growth

A stable microclimate allows crops to devote more energy to fruit development. Unique diffused light technology boosts overall photosynthesis for better sugar content and flavor.

This is a cutting-edge technology. Our colored Agrotextiles selectively filter the light spectrum, sending specific growth signals to plants to stimulate flowering, enhance color, or delay harvest.

Proven in the Field

Engineering & Patents

Thirty years of field problems, turned into design changes, filed as 21 patents held by Joyeyou Industry. Twenty protect what happens under the net — they cluster around three questions growers actually ask. The twenty-first protects how we make the net itself.

Protection systems

5 utility models

How does a net survive a hailstorm intact? Complete orchard systems — anti-hail structures, automatic net tensioning, cherry-orchard protection, wind bracing.

Raschel vs Leno Vineyard Netting: Which Structure Fits Your Vineyard (and Budget)?

Choosing between Raschel and Leno netting isn’t about strength—it’s about system fit. Raschel offers scalability, better conformity, and cost control, making it ideal for most vineyards. Leno suits specific engineered needs but requires tighter handling. Understand your system type and risk profile to select the structure that truly performs.

Drape vs Side Netting: Vineyard Net Installation Methods Explained

Across vineyard projects we’ve supported, we’ve seen a clear result: vineyards that matched the installation system to their labor reality reduced net-related issues by 30–50% within the first season.

Drape systems worked best where machinery and full coverage were available. Side netting delivered better outcomes where labor was limited and repeatability mattered.

Hail Netting Suppliers in South Africa: A Buyer’s Guide

South African apple growers who contact me about hail netting usually mention one of two places: Ceres or Villiersdorp. After a hailstorm wipes out an export season, the question is no longer whether to install nets — it’s which supplier to trust. Local manufacturers like Drape Net (Grabouw) and Knittex have long track records in SA conditions. International options — Tenax, Haygrove — bring global R&D with local teams

Hail Netting Suppliers in Israel: A Buyer’s Guide

Israeli growers who contact me about hail netting often focus on price — but the more important variable is supplier structure. Local manufacturers like Ginegar and Tama give you agronomic support and fast delivery for urgent replacement needs. Direct import from China makes sense above 10 hectares with planned procurement. The mistake I see is small growers importing direct for the price, then finding they cannot get replacement panels for a damaged section mid-season. Match the supply chain to your scale, not to the best price list you found online.

How to Source Shade Cloth from China: A Foreign Buyer’s Factory Evaluation Guide

Most buyers searching for Chinese shade cloth manufacturers start on Alibaba and compare prices. After years of running a shade cloth factory, I can tell you: the price per square metre is the least important number. The UV stabiliser content determines whether your shade cloth lasts 3 years or 8. This guide gives you a 5-question evaluation framework, red flag checklist, and landed cost data for 5 major markets. Start with the specification, then find the factory. — Kevin Lyu, EyouAgro
