Frequently Asked Questions

Q1: What are the main applications of hot-dip galvanized steel pipes?
Answer: Hot-dip galvanized steel pipes are widely used in curtain walls, power transmission towers, communication grids, and steel structure workshops due to their excellent corrosion resistance and load-bearing capacity.
Q2: How is the quality of these pipes inspected during project acceptance?
Answer: Acceptance is primarily based on visual inspection for surface defects like missing plating or bubbles. Addressing these issues promptly ensures the product meets reliability standards for structural use.
Q3: Why might galvanized steel pipes show rust over time?
Answer: Rust occurs if the zinc coating is compromised by acids, alkalis, or humid environments containing hydrogen sulfide. Once the coating is corroded and the underlying steel is exposed, oxidation begins. Phosphating treatments can further inhibit this process.
Q4: How do you prevent cracking when welding in low-temperature environments?
Answer: We recommend using low-hydrogen welding materials, preheating the material (80-200℃), adopting symmetric welding, and ensuring slow cooling for at least 2 hours post-welding to relieve stress.
Q5: What are the available thickness and size ranges for rectangular pipes?
Answer: We provide a thickness range from 1.5mm to 30mm and section specifications from 15mm up to 1000mm, with support for customized lengths.
Q6: What is the typical delivery time for international orders?
Answer: Depending on the order volume and customization requirements, the standard delivery time ranges from 5 to 25 days, supported by efficient logistics via container or bulk vessel.
