We can process various shapes of carbon steel welded air duct and accessories, whether round or square.

The types of carbon steel welded pipe fittings are the same as those of galvanized iron pipe fittings, but the difference is that the processing technology, wall thickness and surface treatment are different. Sometimes it may be necessary for the customer to provide drawings, or we can draw according to the customer's description and submit it to the customer for confirmation.

The carbon steel material we process is generally Q235, and customers can also request other materials.

Customers need to explain to us the paint color on the surface of the air duct, and they can also provide us with swatches, and we color according to the swatches.

Due to the requirements of national environmental protection, we strongly recommend the use of electrostatic spraying surface treatment process.

Our quotation is generally by piece, or by area, by weight can also be quoted.

We may need to ask the customer for other parameters when quoting or processing, such as the turning radius of the elbow, the height of the diameter, etc. In order to try to ensure that the customer's pay is the most cost-effective.
