Frequently Asked Questions
What are the applications of hot-dip galvanized steel pipes?
Hot-dip galvanized steel pipes are widely used in key fields such as curtain walls, power transmission towers, communication & power grids, and building structures due to their excellent quality and practical convenience.
What are the acceptance criteria during project inspection?
Criteria include checking the appearance for defects like missing plating or bubbles. Only when the entire surface is free of these issues is the product deemed qualified for reliable application.
Why do galvanized steel pipes sometimes rust?
Zinc is chemically active and can form a film in humid environments. However, contact with hydrogen sulfide or high humidity can corrode the zinc coating. Once exposed, the underlying steel plate may rust. Phosphating treatment can further inhibit this formation.
How to avoid cracking during welding in low temperatures?
Use low-hydrogen welding materials, preheat to 80-200℃ based on thickness, adopt symmetric welding, and allow for slow cooling for at least 2 hours post-welding to relieve stress.
What size ranges and thicknesses do you offer?
We provide a wide range of specifications from 15mm to 1000mm in section size, with thickness options ranging from 1.5mm to 30mm to meet various structural requirements.
What is the typical delivery time and shipping method?
Our standard delivery time is between 5 to 25 days. We support both bulk vessel and container shipment methods to ensure safe delivery globally.
