Frequently Asked Questions
Why choose hot-dip galvanization over other coatings?
Our 85 μm-thick zinc coating provides 3-4 times longer corrosion resistance versus electroplating, complete coverage including recesses, and 50+ year lifespan in typical greenhouse environments.
What customization options are available?
Dimensions: rack lengths 0.5-12m with modular joining; 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 for UV protection.
How does this system handle high humidity?
The galvanized layer withstands 100% relative humidity continuously, resists fertilizer and chemical corrosion (pH 5-12), and passes 2000+ hour salt spray testing.
What maintenance is required?
Zero lubrication design with self-lubricating polymer bushings optional. Annual inspection recommended to check for physical damage, remove debris from gear teeth, and verify bolt tightness.
What quality certifications do you have?
Material: ISO 1461 (hot-dip galvanizing); Gears: DIN 3961 Class 7 precision; System: CE, RoHS, ISO 9001:2015.
What's your production lead time?
Custom orders: 30-45 days (galvanizing adds 3 days).
