Tube and Profile Rolling Machines

A tube and profile rolling machine, or tube roller, forms tube, section and bar into precise radii, rings and bows. It is at work in metal fabrication, mining, oil and gas and heavy engineering, wherever curved parts are made from straight stock without crushing the cross-section.

That depends on diameter, wall thickness, material and radius. A section roller for roll bending suits large radii, rings and bows, while hydraulic tube bending suits tighter radii for railings and tube structures. Which of the two machines fits your cross-sections and materials is something we settle in the enquiry.

The machines are built to European testing standards. The related documentation is available on request, so you can confirm the machine meets the requirements that apply to your operation.

Yes. Manually adjusted tube rollers are clear to operate and robust, which suits training workshops and apprenticeships in metal fabrication. For a first step into repeatable work, motorised rolling machines are a good fit.

Service in South Africa runs through local service partners, with a base in Germiston near Johannesburg. Common spare parts come from the central warehouse, and a ten year spare parts supply commitment applies. Availability and delivery time are on request.

Roll bending is economical for large radii and works the section over three rolls, which is the classic section roller job. Mandrel bending suits tight radii and thin-walled tube, where an internal mandrel supports the wall so it does not collapse. The KNUTH focus is on roll bending and hydraulic tube bending.

The usual materials are mild steel, stainless steel, aluminium and copper, as round tube, square tube, flat steel or angle section. Soft materials allow tighter radii, while higher-strength grades need more force and larger radii. The exact ranges are listed with the individual machines in the product grid.

CNC-controlled machines are found on the market, mainly for large, repeating series. The current KNUTH range covers manual to hydraulic machines. Motorised or CNC versions are on request.

Pricing is on request. The price depends on the process, the capacity, the drive and the accessories, so there is no single list price. You receive a quotation per configuration. Choose the machine in the product grid and send an enquiry.

Yes, with the matching rolls and tooling. As a section roller it forms angle section and flat steel into railings, rings and frames alongside round and square tube.
