High-Strength Gear-Rack Greenhouse Ventilation Components

Gear-Rack Greenhouse Ventilation & Shading Components

Product Overview

Our gear-rack greenhouse ventilation & shading components provide durable, precision-driven control for optimal climate management in commercial and hobby greenhouses. Designed for smooth, automated operation, these systems ensure efficient airflow regulation and sunlight modulation to enhance plant growth while reducing energy costs.

Key Features

✔ Robust Gear-Rack Mechanism – Ensures reliable, low-maintenance movement for ventilation windows, louvers, and shade screens.
✔ Modular Design – Customizable configurations to fit various greenhouse sizes and structures.
✔ Weather-Resistant Materials – Built to withstand UV exposure, humidity, and temperature fluctuations.
✔ Easy Integration – Compatible with manual, motorized, or smart automation systems.
✔ Energy-Efficient – Reduces dependency on artificial cooling, lowering operational costs.

Applications

• Commercial greenhouses (vegetables, flowers, nurseries)
• Research & horticultural facilities
• Retractable roof & side vent systems
• Shade net/curtain deployment

FAQ

1. Why choose hot-dip galvanization over other coatings?

• Our 85μm-thick zinc coating (per ASTM A123) provides:

  • 3-4× longer corrosion resistance vs electroplating

  • Complete coverage (including recesses)

  • 50+ year lifespan in typical greenhouse environments

2. What customization options are available?

• Dimensions: Rack lengths 0.5-12m (modular joining available)

• Gear Modules: 1.0-4.0mm (standard), up to 6mm for heavy loads

• Mounting: Pre-drilled holes, flanged designs, or custom brackets

• Finishes: Additional powder coating (RAL colors) for UV protection

3. How does this system handle high humidity?

• The galvanized layer:

  • Withstands 100% RH continuously

  • Resists fertilizer/chemical corrosion (pH 5-12)

  • Passes 2000+ hour salt spray testing (ASTM B117)

4. What maintenance is required?

• Zero lubrication design (self-lubricating polymer bushings optional)

• Annual inspection recommended:

  • Check for physical damage

  • Remove debris from gear teeth

  • Verify bolt tightness (torque specs provided)

5. What's the load capacity?

• Standard ranges:

  • Dynamic: 500-5000N (depends on module size)

  • Static: 2× dynamic capacity

• Custom high-capacity versions available (up to 10kN)

6. What quality certifications do you have?

• Material: ISO 1461 (hot-dip galvanizing)

• Gears: DIN 3961 Class 7 precision

• System: CE, RoHS, ISO 9001:2015

7. How does shipping work for long racks?

• Standard: Cut to 2m sections for container shipping

• Oversized: Special crating for ≤12m lengths (+15% fee)

• Includes protective end caps to prevent transit damage

8. What's your production lead time?

• Custom orders: 30-45 days (galvanizing adds 3 days)
