Quick answer: use crop type, greenhouse layout, support method and expected service life as the selection criteria before comparing price.
Why coating matters
Greenhouse systems operate in humid, fertilized and sometimes high-temperature environments. Coating selection affects corrosion resistance and replacement cycle.
Cost and service life
Higher coating weight usually improves corrosion resistance, but it also affects cost. The right option depends on project climate, crop type and expected lifetime.
Project recommendation
For overseas buyers, coating should be confirmed together with steel thickness, profile structure and packing plan.
Buyer checklist
- Assess humidity and fertilizer exposure
- Balance cost against expected lifetime
- Ask for material confirmation before ordering
- Use project photos and drawings during specification
