Frequently Asked Questions (FAQ)
Q1: What is the difference between pre-galvanized and hot-dip galvanized pipe?
A: Pre-galvanized pipe is coated with zinc before forming, resulting in a thinner but more uniform coating. It is ideal for indoor or greenhouse applications where moderate corrosion resistance is needed. Hot-dip galvanized pipe has a thicker coating and is better for outdoor or harsh environments.
Q2: Can this pipe be used for high-tunnel greenhouses?
A: Yes, the 48.3mm OD is a common size for high tunnel and hoop house frames. The Q195 material provides sufficient strength for typical greenhouse loads, including wind and snow.
Q3: What wall thickness do you recommend for a greenhouse frame?
A: For most greenhouse structures, 1.5mm to 2.0mm wall thickness is sufficient. If you are building in an area with heavy snow or wind, we recommend 2.5mm or above. You can also consult our technical team for a customized recommendation.
Q4: Do you offer custom lengths? What is the maximum length?
A: Yes, we can cut the pipe to any length from 1m to 12m. The standard length is 6m. Please specify your required length when placing an order.
Q5: How is the pipe packed for export?
A: Our pipes are tightly bundled with steel straps, wrapped in waterproof plastic or paper, and loaded into containers. For sea freight, we also add anti-rust coating inside the bundle to protect against moisture.
Q6: Can I get a sample before bulk order?
A: Absolutely. We offer free samples (you only pay shipping cost) for quality evaluation. Contact our sales team to arrange a sample shipment.
Q7: What is the lead time for a 20-foot container?
A: Typically, lead time is 15–20 days after receiving the deposit. For urgent orders, we can expedite production to 10–12 days with a small surcharge.
Q8: Which ports do you ship from?
A: We mainly ship from Shanghai Port, Tianjin Port, Qingdao Port, and Ningbo Port. The port can be selected based on your destination and shipping cost.
