Packing and transport

Customer Case

An Australian customer purchased powder coated pre-galvanized steel square tubes. Upon receiving the first delivery, the customer tested the adhesive strength between the powder and the square tube surface and found it to be insufficient. We held technical meetings to address this issue, continuously testing solutions. We polished the surface of the square tube and sent it to the heating furnace for pre-heating before coating. Through persistent testing, collaboration, and finding optimal methods, the final product successfully satisfied the customer. Currently, this customer purchases a large volume of products from our factory every month.

Frequently Asked Questions

What types of galvanized steel pipes do you manufacture?

We manufacture both Hot Dip Galvanized Steel Pipes and Pre-Galvanized Steel Pipes, configured in round shapes to suit different industrial requirements.

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

Our steel pipes feature a wall thickness range of 0.6mm to 20mm, outer diameters ranging from 1/2’’ (21.3mm) to 16’’ (406.4mm), and standard lengths between 1m and 14m which can also be tailored based on customer needs.

What is the difference in zinc coating weight between pre-galvanized and hot dip galvanized pipes?

Pre-galvanized steel pipes have a zinc coating density of 40–220 G/M², whereas hot dip galvanized steel pipes carry a heavier zinc coating of 220–350 G/M² for enhanced corrosion resistance.

Which standards and material grades do your products support?

Our products meet ASTM, DIN, JIS, and BS standards. We work with multiple material grades including Q195 to Q345, 10#, 45#, S235JR, GR.B-D, STK500, and BS1387.

What is your typical delivery timeframe and payment structure?

We offer a delivery time of 25 days following the receipt of your deposit. Our payment terms require a 30% deposit upfront, with the remaining balance due after receipt of the Bill of Lading (B/L) copy.

What custom processing capabilities do you offer to resolve powder coating adhesion issues?

As experienced in our previous customer cases, we can polish the surface of pre-galvanized square tubes and pre-heat them in our furnace before powder coating to ensure maximum coating adhesion and satisfaction.
