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.
Shade & reflective textiles
3 utility models
How do you control light and temperature without starving the crop? Weave structures for reflective screens, ground covers, and thermal curtains.
Fasteners & installation
10 utility + 2 design
The small parts that decide whether a net is still there after a storm — hooks that tension a net without tearing its edge, clips, connectors, and off-season storage hardware.
Manufacturing equipment
1 invention patent
The twenty-first patent protects the process, not the product — an in-line film-slitting system that keeps tape width and yarn weight consistent across every roll we produce.

Product Coverage
A Solution for Every Challenge
Rain Cracking in Chile, sunburn in Australia, birds in a New Zealand vineyard — every growing region has its own way of costing you a crop. Over 30 years, we have built a specific, field-proven answer for each of them.
No Two Orchards Are the Same.

The best solutions are born from collaboration. Tell me about your land, your crop, and the problem that keeps coming back — and I will come back with a protection strategy built for exactly that.

Sharing is the Best Way to Grow

“The more I share, the more I grow.” I firmly believe this.
Here, I’ll share what I’ve learned to help you better understand and use agrotextiles.

In real greenhouse and tunnel projects we’ve supported, the biggest mistake I keep seeing is treating “25 mesh vs 40 mesh” as a small upgrade. It isn’t. That one step changes which pests you can reliably stop (especially aphids, whiteflies, and SWD), and it also changes how your structure breathes—temperature, humidity, and disease pressure. This guide breaks the decision down the way our technical team does in the field: aperture logic + pest morphology first, then ventilation reality.

The vineyard growers who call me after a failed net season — it’s almost never the wrong net type. It’s a drape system on a crew that can’t manage removal, or side netting on rows too tight for it.

In Marlborough and Central Otago blocks, switching from drape to side netting cuts harvest-period labour 25–30%. In Chilean Colchagua where hail and birds hit the same season, one overhead canopy handling both threats pays back in two seasons. The net choice follows the risk and the crew — not the other way around.

Bird pressure on U.S. fruit crops varies dramatically by region and species — what works in a Michigan blueberry field differs from a California strawberry bed. Most growers undersize their mesh (using 25mm when 14mm is needed for finches) or skip UV stabilizer specs and wonder why netting fails in year 3.

The Section 301 tariff math matters: at 25–34.7% duty on Chinese-made netting, domestic suppliers can be cost-competitive once freight and tariff are factored into the landed price. Always compare landed cost, not ex-works quote.

Johannesburg growers often apply Cape Town shade cloth specs without adjusting for altitude. At 1,753m, UV intensity is 20-25% higher than sea level — a shade cloth that lasts 7 years in Cape Town may fail in 4-5 years in Gauteng if the UV stabilizer percentage was not verified before purchase.For commercial greenhouse operations (roses, tomatoes), the bigger oversight is shade percentage accuracy

— Kevin Lyu, EyouAgro
Growers who contact me expecting that a larger supplier automatically means a safer purchase are often surprised by what I tell them. The real risk in sourcing bird netting is not supplier size—it is specification mismatch.
Get the species list from your regional agricultural extension office before you request quotes, and insist that every supplier confirms the aperture is tested to ±1 mm tolerance.
As climate volatility, bird pressure, and heat stress increase, vineyard netting is shifting from a reactive fix to a strategic foundation for stable yields and consistent fruit quality. This beginner guide explains what vineyard netting is, the key risks it reduces, and how growers can start thinking about net types and installation methods.
Operating a vineyard without netting exposes growers to hidden, compounding risks—from bird damage and hail losses to heat stress, disease pressure, and rising labor costs. This article explains why netting is no longer optional but a critical risk‑management tool for stabilizing yields, protecting grape quality, and ensuring predictable vineyard performance in today’s volatile climate.
In working with vineyard clients at an early planning stage, I’ve noticed that most questions start with net types and prices, rather than risk and usage scenarios.

Many vineyards begin with a general understanding of bird or pest pressure, but the real challenge is translating that awareness into the right netting approach.

This article reflects the kinds of baseline questions we typically discuss before moving into more detailed system or material decisions.
Overhead netting isn’t just a net—it’s a long-term structural system. This guide walks you through key decisions, step-by-step installation, tensioning, and maintenance planning to ensure durability and performance. Perfect for vineyards facing repeated hail or bird risks and seeking consistent, season-to-season protection with predictable results.
Proper storage protects your vineyard nets. Learn how inspection, drying, and correct rolling methods can extend net life and reduce damage. Avoid UV, moisture, and poor folding practices. This quick guide offers best practices for safe seasonal storage based on real vineyard operations.
Most vineyard nets don’t fail—they get damaged. This guide helps growers extend net life through early damage detection, proper repair methods, and smart storage habits. Learn how to treat punctures, tears, and fraying edges with techniques tailored to your net type—drape, side, or overhead. Reduce emergency fixes and protect your investment with a simple, repeatable maintenance routine.
All articles are written based on first-hand project experience, on-site installation work, and long-term performance data collected from orchards, vineyards, greenhouses, and commercial growers worldwide.
