FAQ

Q: What can pipes and tubes be used for?

A: Since pipe and tube is both durable and lightweight, it's commonly utilized by the construction industry in commercial and residential buildings, as well as in industry sectors including power, water, sewer, manufacturing and more.

Q: What is your minimum order quantity?

A: Our minimum order quantity is 50 kg. Larger quantity, lower price.

Q: What is the advantage of pipe and tube?

A: Using stainless pipe and tubes gives you a durable product that will last for decades. Steel is a reliable material that is easy to maintain and install. Stainless steel is very low-maintenance, and because of its corrosion-resistant properties, it's unlikely it will need to be replaced for decades.

Q: How do you control product quality?

A: From the selection of raw materials to transportation packaging, every production process will be testing and evaluated. Only products that have passed all tests can be delivered for export.

Q: Can you provide processing services?

A: Yes, we also provide processing services to our customers. It is one of our goals to provide specialized services such as bending, water cutting, laser cutting, digging holes, welding, slitting of coils, and other fabrications according to the drawings.

Q: Can you provide samples?

A: For small parts, we can provide free sample of regular sizes, but the shipping costs will be borne by you. For large parts sample, we will include it in the order amount. Please confirm with our sales department for your specific requirements.
