A Note from Inside the Industry

I run an agricultural textile factory in Shanghai that manufactures greenhouse shade screens — Aluminet, energy-saving screens, blackout screens, and standard HDPE shade cloth. I have been doing this for 28 years.

This guide is written from inside the industry. I have an obvious interest in you choosing us. I am being upfront about that so you can weigh everything accordingly.

What I can offer that a generic “top suppliers” list cannot: technical specifics about how greenhouse shade products are actually manufactured, what separates a real Aluminet producer from a reseller, and the questions that separate serious factories from trading companies.

Greenhouse shade is more complex than open-field shade cloth. Inside a greenhouse, your shade screen is not just blocking sunlight — it is managing light diffusion, controlling temperature, and in many cases reducing heating and cooling costs by 40-60%. The product you choose directly affects crop yield and energy bills. Getting it wrong is expensive.

Why “Top Greenhouse Shade Cloth Suppliers” Lists Will Not Help You

Most supplier lists you find online mix up three completely different products: standard HDPE shade cloth, Aluminet reflective screens, and internal energy-saving screens. These are manufactured on different equipment, using different materials, and serving different functions. Listing them together is like comparing a window blind with double-glazed insulated glass — they both go on windows, but that is where the similarity ends.

A factory that makes excellent knitted shade cloth for open-field use probably cannot manufacture Aluminet to greenhouse-grade specifications. The aluminum coating process requires dedicated production lines that most shade cloth factories lack.

The more useful starting point is not “who are the top suppliers?” but “what problem am I solving?” Are you managing heat? Diffusing light? Reducing energy costs? Controlling photoperiod? The answer determines which type of factory you need.

The Product Decision: Which Greenhouse Screen Do You Actually Need?

Before you compare factories, you need to resolve the product question. Here are the five main categories of greenhouse shade screens, and they are not interchangeable.

The most expensive mistake I see in greenhouse orders: a buyer specifies “50% Aluminet” when what they actually need is an energy-saving screen with 50% light transmission. Those are two different products at very different price points — and they perform differently in winter. One reflects heat. The other traps it. If you are heating your greenhouse through European winters, that distinction is worth thousands in annual energy costs.

5 Questions to Ask Every Chinese Greenhouse Screen Manufacturer

These questions will separate real manufacturers from trading companies, and factories with genuine greenhouse expertise from those that simply list “Aluminet” on their product page.

1. Which screen types do you manufacture on your own production lines?

Aluminet requires specialized equipment — specifically, an aluminum coating line that bonds aluminum strips to HDPE tape before weaving. Many suppliers who list Aluminet on their website actually source it from a handful of factories that have this equipment. There is nothing wrong with sourcing, but you should know whether you are buying from a manufacturer or a middleman. Ask for production video of the coating line. If they cannot show it, they are not making it.

2. Can you provide independent test data for energy savings and light transmission?

Real greenhouse screens are tested for thermal resistance (EN 14500 or ASHRAE equivalent), light transmission percentage, and reflection percentage. Factory spec sheets are not sufficient — any factory can write “50% energy saving” on a datasheet. Ask for independent lab results. The screen’s performance under standardized test conditions is what matters, not marketing claims.

3. What is your experience with greenhouse climate computer integration?

Modern commercial greenhouses use Priva, Hoogendoorn, or Ridder climate systems that automate screen deployment based on temperature, light, and humidity readings. Your screen must be compatible with motorised screen systems and fit standard racking hardware. A factory without experience integrating greenhouses will supply a screen that may not fit standard bay widths or integrate with your automation system.

4. What export documentation and compliance can you provide?

Depending on your market, you will need specific documentation. REACH compliance for EU imports. Phytosanitary certificates for Australia and New Zealand. Product testing certificates appropriate to your country. A factory that exports regularly will have these processes established. A factory that mainly sells domestically will struggle, and the delay will cost you time.

5. What are your payment terms and order process?

Standard payment terms for Chinese greenhouse screen manufacturers: 30% deposit, 70% before shipment via T/T (telegraphic transfer). Be cautious of factories that demand 100% upfront or offer terms that seem too flexible — both can indicate risk. For larger orders, L/C (letter of credit) is standard and protects both parties.

Red Flag Checklist

In 28 years of manufacturing, I have seen every variation of misrepresentation in this market. Here are the warning signs to watch for.

• Claims to manufacture Aluminet but cannot show an aluminum coating production line
• Lists energy-saving percentages without third-party test data to back them up
• Cannot specify screen width to match standard greenhouse bay widths (typically 3.2m, 4.0m, 4.8m, 6.4m, 8.0m, 9.6m, or 12.8m)
• Price for Aluminet is similar to standard HDPE shade cloth — if it seems too cheap, it is not real Aluminet
• No experience supplying screens to greenhouse builders or greenhouse system integrators
• Uses generic product images that appear on multiple supplier websites
• Cannot explain the difference between knitted shade cloth and woven climate screen
• Offers every product category imaginable — shade cloth, anti-hail, bird netting, insect netting, safety nets — with no clear specialization

Verified Chinese Greenhouse Screen Manufacturers: Short List

Disclosure: I am including my own company (EyouAgro) in this list. I am also including competitors that I can verify are real manufacturers with actual production capability. I have excluded companies from the original version of this article that I could not independently verify as active manufacturers.

Hefei Grand Nets Co., Ltd.

Location: Hefei, Anhui Province
Products: Shade nets, ground cover, agricultural netting
Best for: Standard HDPE shade cloth for basic greenhouse external shading. They are an established manufacturer with consistent quality for conventional shade netting products.
Limitations: Not a manufacturer of Aluminet or internal energy-saving screens requiring specialized coating equipment. If your greenhouse requires climate screens for energy management, this is not the right factory.

Shandong Binzhou Chengxiang Net Co., Ltd.

Location: Binzhou, Shandong Province
Founded: 1993
Products: HDPE shade cloth, plastic film, olive collection nets
Best for: Budget standard shade cloth in large quantities. Shandong Province is a major production hub for agricultural netting, and factories there benefit from lower production costs.
Limitations: Product range centres on standard knitted and woven shade cloth. Not suitable for buyers needing precision greenhouse climate screens or Aluminet.

BN Netting

Products: Shade netting, drip edge netting, vented shade cloth, greenhouse curtains
Best for: Buyers who need a range of greenhouse accessories alongside shade cloth. Their product line includes drip-edge and vented-shade products that some greenhouse builders find useful.
Limitations: More of a supplier than a specialised climate screen manufacturer. Not the right choice for high-performance Aluminet or energy-saving screens.

EyouAgro (Joyeyou Co., Ltd.)

Location: Qingpu, Shanghai
Founded: 1996
Production: 8 production lines, 21 patents
Full product range:

• Aluminet reflective screens
• Internal energy-saving screens
• Blackout screens
• Diffusion shading screens
• Standard HDPE shade cloth

We manufacture Aluminet on dedicated coating lines — not all Chinese shade cloth factories can say this. Our factory was built specifically for greenhouse climate screens, and we have supplied screens to greenhouse projects in Australia, the Netherlands, Spain, and across North America.

Best for: Greenhouse growers and greenhouse builders needing Aluminet or energy-saving screens with specifications that match Svensson- or Ludvig-equivalent performance at factory-direct pricing. Orders above 20,000 m2.
Limitations: Not ideal for small greenhouse hobbyists or buyers who only need basic low-cost HDPE shade netting. Our minimum for specialty screens is 5,000 m2, and our pricing reflects the manufacturing complexity rather than that of commodity shade cloth.

What We Do Not Do

Transparency works both ways. Here is what we will not do, even if you ask.

• We do not produce standard shade cloth and label it as Aluminet. This is the most common fraud in this product segment, and we will not participate in it.
• We do not accept orders below 5,000 m2 for specialty screens. The setup cost for Aluminet production runs makes smaller orders uneconomical for both parties.
• We do not claim compatibility with specific greenhouse climate systems without verification. If you tell us you are running Priva, we will confirm our screens work with your exact configuration before quoting.
• We do not provide on-site screen installation. We manufacture and ship. For installation, we recommend working with your local greenhouse builder or contractor.

First-Time Sourcing Process

If you have not imported greenhouse screens from China before, here is a realistic timeline.

Total first-order timeline: approximately 3-4 months from initial inquiry to delivery. Repeat orders are faster because specifications are already confirmed.

Landed Cost by Target Market

The factory-gate price is only part of the story. Here is what to budget for landed cost when importing greenhouse screens from China. These are estimates based on a standard 20ft container of Aluminet screens (approximately 8,000-12,000 m2 depending on weight).

Tariff notes: Australia and New Zealand import greenhouse shade screens from China at 0% duty under their respective Free Trade Agreements (ChAFTA and NZ-China FTA). US tariffs are the highest: the MFN base rate ranges from 5% to 14% depending on how your product is classified (HTSUS 5608 for knotted netting, 6005 for warp knit fabric, or 6307.90 for made-up textile articles), plus an additional 25% under Section 301. Confirm the exact HTSUS classification and current rate with your customs broker before calculating landed cost — trade policy changes frequently.

As a rule of thumb: for Australia and New Zealand, landed cost is typically 15–25% above FOB (freight and compliance costs only, no duty). For the EU, expect 25–35% above FOB. For the USA, expect 45–65% above FOB due to the Section 301 tariff overlay.

When Does Direct Sourcing from China Make Sense?

Direct sourcing is not always the right choice. Here is a decision framework.

My honest advice: If you need standard HDPE shade cloth in small quantities, buy locally. The savings from China do not justify the logistics for commodity products. Where direct sourcing pays off is specialty greenhouse screens — Aluminet, energy-saving screens, blackout screens — where local supply is limited and factory-direct pricing saves 30-50% compared to importing through a distributor.

Frequently Asked Questions

What is the difference between Aluminet shade cloth and standard HDPE shade cloth?

Standard HDPE shade cloth absorbs and blocks sunlight. Aluminet reflects solar radiation while allowing diffused light through. The practical difference: HDPE shade cloth reduces light but traps heat underneath. Aluminet reflects heat away from the greenhouse while maintaining useful light levels for plant growth. Aluminet also provides thermal insulation in winter, reducing heating costs. Standard HDPE does not. They require different manufacturing equipment, and Aluminet typically costs 2-3 times more than equivalent HDPE shade cloth.

How do I verify a Chinese factory actually manufactures Aluminet?

Ask for a video tour of their aluminum coating line. Real Aluminet production requires a specific process: aluminum strips are coated onto HDPE tape before weaving. If the factory cannot show this equipment, they are buying Aluminet from someone else and reselling it. Also ask for production capacity figures — a real manufacturer will know their daily output in square metres. Finally, request references from greenhouse builders or integrators they have supplied directly.

What screen width do I need for my greenhouse?

Screen width must match your greenhouse bay width. Standard bay widths are 3.2m, 4.0m, 4.8m, 6.4m, 8.0m, 9.6m, and 12.8m. Your greenhouse builder or screen system manufacturer (Priva, Ridder, etc.) can confirm the exact width required. Ordering the wrong width means the screen either does not cover the bay completely (leaving thermal gaps) or bunches up in the track (causing motor strain and uneven deployment). Always confirm width before ordering.

What energy savings can I expect from an internal climate screen?

A properly installed internal energy-saving screen typically reduces heating costs by 40-60% depending on the screen type, greenhouse design, and climate. In summer, the same screen can reduce cooling load by 30-50% through solar reflection. The actual savings depend on your local energy costs, greenhouse insulation, and how the screen is integrated with your climate control system. Ask the manufacturer for test data based on EN 14500 or equivalent standards rather than relying on marketing claims.

What is the minimum order for greenhouse screens from a Chinese factory?

For standard HDPE shade cloth, most factories accept orders from 5,000 m2 (approximately one 20ft container). For specialty screens like Aluminet and energy-saving screens, minimums are typically 5,000-10,000 m2 due to production setup costs. Some factories will accept smaller trial orders at a higher per-metre price, but this varies. If your requirement is below 5,000 m2, consider whether a local distributor or a consolidated order through a trading company makes more sense.

Conclusion

Sourcing greenhouse shade cloth from China can save significant money on specialty screens, but it requires more product knowledge than most buyers expect. The first step is not finding a supplier — it is resolving the product question. Aluminet, energy-saving screens, blackout screens, and standard shade cloth are different products made by different types of factories.

Once you know what you need, use the five evaluation questions and the red flag checklist to assess potential suppliers. Prioritise factories that can demonstrate actual manufacturing capability for your specific screen type, provide independent test data, and show experience with greenhouse system integration.

Whether you source from us or from another manufacturer, the framework in this guide will help you make a more informed decision. The greenhouse screen you install will be in service for 5-10 years. Spending an extra month on due diligence before ordering is time well invested.

Shade Netting Suppliers in Johannesburg: A Buyer’s Guide

Johannesburg growers often apply Cape Town shade cloth specs without adjusting for altitude.

Shade Net Suppliers in UAE: A Buyer’s Guide

UAE greenhouse operators who contact me about shade cloth often believe their problem is finding the right shading percentage. In my experience, it is rarely that.
