Hot‑dip galvanized greenhouse steel pipe is one of the most widely‑used structural frame materials for modern agricultural facilities. The base tube is manufactured from premium Q195 and Q235 low‑carbon steel, featuring stable chemical composition, good ductility and excellent bending performance, which makes it easy to arch and shape for curved greenhouse roofs.

After forming, the pipes go through complete hot‑dip galvanizing treatment. A thick, tightly‑bonded zinc‑alloy coating is formed on both inner and outer surfaces. This galvanized layer delivers strong rust‑proof and anti‑corrosion capacity, protecting the steel substrate from moisture, rain, dew and soil erosion in long‑term outdoor farm environments.

Our greenhouse pipes possess high compressive strength and outstanding wind‑snow load‑bearing capacity, capable of standing harsh weather conditions such as strong wind, heavy snow and hail. The finished surface is smooth, uniform and burr‑free, so it will never cut or scratch plastic greenhouse film, shade net and other covering materials.

A full range of standard sizes are kept in our warehouse, covering common outer diameters from 20mm‑60mm and multiple wall‑thickness choices. Custom cut‑to‑length service is available according to your greenhouse drawing requirements. Pre‑bent arch pipes can also be supplied upon request.

These galvanized frame tubes are suitable for single‑span vegetable greenhouses, fruit seedling shelters, flower‑plant greenhouses, livestock breeding sheds, aquaculture facilities, multi‑span connected greenhouses and other agricultural projects. We provide large‑volume bulk supply, flexible delivery schedule and one‑stop steel‑pipe procurement solutions for overseas importers, contractors and agricultural project purchasers.
