Frequently Asked Questions

What is the difference between ERW and seamless pipes?

ERW (Electric Resistance Welded) pipes are made by rolling steel sheets and welding the seam, offering cost efficiency and consistent quality. Seamless pipes are formed without a weld seam, typically used in high-pressure applications. We specialize in high-quality ERW pipes suitable for most structural and industrial uses.

Are your galvanized pipes hot-dip or electro-galvanized?

All our galvanized steel pipes are produced using the hot-dip galvanizing process, which provides a thick, durable zinc coating that offers superior corrosion resistance compared to electro-galvanizing.

Can you provide custom pipe sizes and lengths?

Yes, we offer customization for pipe diameters, wall thicknesses, and lengths based on client requirements. Please contact us with your specifications for a quote.

Do you offer OEM/ODM services?

Yes, we support OEM and ODM orders. We can produce pipes under your brand name with customized packaging and labeling.

What certifications do you have?

Our products are manufactured under ISO-certified processes. We can provide material test certificates (MTC) and comply with ASTM, API, and other international standards upon request.
