For custom products, feel free to send a request detailing your specific requirements to our sales team, who will know how to supply what you need..

Steel tubes for your particular application

Our steel tubes are used mainly as used as construction materials, for pipework and more generally as building supplies. They are also suitable for mechanical or heating applications. Our steel tubes often serve as a base component in a more elaborate combination of elements. Regardless of your field and the way you intend to use the steel tubes you require, our sales teams is at your service to supply you with high-quality products that meet your needs.

In addition to our permanent wide range of round, square and rectangular tubes, Muller Aciers specialises in steel tubes in non-standard lengths, diameters and thicknesses.
Contact our Sales Team for a choice of tubing for your own applications, such as gas tubing, welded or seamless; precision tubing; rolled surface or descaled; flanged tubes for metalworking, etc.
