Hot-Dip Galvanized Greenhouse Ventilation Gear System Components

Customized Hot-dip Galvanized Greenhouse Shelter Ventilation And Shading Gear System Components

Product Overview

Our high-performance rack and pinion gear system is specially designed for greenhouse shelters, providing durable, corrosion-resistant automation for ventilation and shading systems. Featuring hot-dip galvanized coating, these components ensure long-term reliability in humid and high-corrosion agricultural environments.

Key Features

✔ Superior Corrosion Protection – Hot-dip galvanized surface treatment provides enhanced rust resistance, ideal for greenhouses with high humidity and chemical exposure.
✔ Precision Engineering – CNC-machined rack and pinion gears ensure smooth operation, low backlash, and high load capacity.
✔ Customizable Design – Available in various module sizes, lengths, and tooth profiles to match specific greenhouse requirements.
✔ Easy Installation & Low Maintenance – Pre-drilled mounting holes and modular assembly reduce setup time.
✔ Compatibility – Works with electric actuators, manual cranks, or pneumatic drives for flexible automation.

Applications

• Automated greenhouse roof vents

• Retractable shading systems

• Sidewall ventilation controls

• High-tunnel and multi-span greenhouse shelters

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)
