Frequently Asked Questions (FAQ)
Q: What is the difference between hot-dipped galvanized and pre-galvanized steel pipe?
A: Hot-dipped galvanizing immerses the pipe in molten zinc, creating a thicker, more uniform coating that offers superior corrosion resistance for outdoor and harsh environments. Pre-galvanized pipes have a thinner coating applied before forming, suitable for indoor use.Q: Can you provide pipes with custom lengths or threading?
A: Yes, we offer custom lengths from 1m to 12m, and we can supply threaded ends, grooved ends, or plain ends according to your project needs. Minimum order quantity may apply.Q: What standards do your pipes comply with?
A: Our pipes are manufactured to meet ASTM A53, BS 1387, EN 10255, and ISO 65. We can also produce according to other standards upon request.Q: How is the zinc coating thickness measured?
A: We use magnetic thickness gauges and weigh samples to verify coating weight, ensuring it falls within the specified range (typically 200-600 g/m²).Q: Are these pipes suitable for drinking water systems?
A: Yes, the zinc coating is non-toxic and safe for potable water applications. Our pipes comply with relevant health and safety regulations.Q: What is the typical delivery time for bulk orders?
A: Delivery time depends on quantity and specifications. Generally, it takes 15-30 days after order confirmation. We can expedite for urgent projects.Q: Do you offer samples for quality testing?
A: Yes, we provide free samples for evaluation, but the buyer covers shipping costs. Contact our sales team to arrange.
