Packing and Transport

Customer Case

Australian customer purchase powder coating pre galvanized steel square tube. After customers receives the goods for the first time. Customer tests adhesive strength between the powder and the surface of the square tube. Customers test powder and square surface adhesion is small. We have meetings with customers to discuss this problem and we do tests all the time. we polished the surface of the square tube. Send the polished square tube to the heating furnace for heating. We tests all the time and discuss with customer all the time. We keep finding ways. After many tests, the final customer is very satisfied with the products. Now customer purchase a large number of products from factory every month.

Frequently Asked Questions

What are the dimensions and thickness specifications of your steel pipes?

Our steel pipes feature a wall thickness range of 0.6mm to 20mm, with outer diameters ranging from 1/2’’ (21.3mm) to 16’’ (406.4mm). The lengths can be customized from 1 to 14 meters according to specific customer requirements.

What is the zinc coating density for pre-galvanized vs. hot-dip galvanized pipes?

Pre-galvanized steel pipes have a zinc coating density of 40–220 G/M², while hot-dip galvanized steel pipes have a higher zinc coating density ranging from 220 to 350 G/M² to ensure optimal corrosion resistance.

What international standards and materials do you support?

Our production complies with ASTM, DIN, JIS, and BS standards. Available steel grades and materials include Q195 to Q345, 10#, 45#, S235JR, GR.B-D, STK500, BS1387, and others. We hold ISO, BV, CE, and SGS certifications.

Do you hold any unique product patents or special designs?

Yes, we hold three unique patents for Groove pipes, Shoulder pipes, and Victaulic pipes, distinguishing our products from standard manufacturing lines.

How do you resolve custom quality requirements, such as powder coating adhesion?

We work closely with clients to solve custom challenges. For instance, when a client needed better surface adhesion for powder coating, we adjusted our process by polishing the square tube surface and heating it in a specialized furnace until the adhesion met rigorous standards.

Where is the products' loading port and what is the delivery timeline?

Our main loading port is Tianjin/Xingang, located just 40 kilometers from our factory (the largest port in Northern China). Standard delivery times are approximately 25 days after receiving your deposit.
