Sonco Tube FAQs

What do the coatings do for the products?

Coatings add to the life of our products by providing longer durability against normal environmental corrosion. Coatings improve the appearance of the tubing, and they prepare the tube surface for specific end uses.

Do you produce anything other than in-line galvanized mechanical tubing?

Yes. We also produce tubing products that are not coated, such as HRP&O (Hot rolled pickled and oiled), Cold Rolled (CR), and pre-galvanized substrate.

Can I buy less-than-truckload quantities?


Can I weld in-line galvanized mechanical tube?

Yes. Allied’s tube can be easily welded because we use pure 99.99% Organic zinc grade for our in-line products. Our in-line galvanized tube is applied in a controlled process on the mill achieving a smooth, even coating. This process makes it much easier to weld and reduces the amount of hazardous fume emissions in the welding process compared to hot-dip galvanized.
