Sheet metal profiling machines for coil-fed production

TRIS beading and hemming machines

TRIS sheet metal beading machines give parts strength and a clean finish: beads, edges and hems on iron, aluminium, copper and stainless steel, with three forming units on a single machine. Single-phase power makes TRIS as practical on a construction site as in the workshop.

AC Bend electric panel bender

When the profile is a bend rather than a bead, AC Bend takes over. This CNC sheet metal forming machine shapes flanges, boxes, profiles, radius bends and negative bends at high speed, even on complex geometries, and can be installed in line with Produtech coil-fed machines: parts cut from the coil are bent in the same flow and leave the plant as finished components. 

Sheet metal profiling from coil: the advantages

Profiling is where a part takes its final form, but most of its cost is decided earlier, by the material it comes from. Starting from the coil changes the numbers of the whole cycle.

• Less scrap, parts of any length: nesting on a coil with no length limit reduces waste by 20 to 30% compared with pre-cut sheets, according to Produtech estimates.
• Lower material cost: a coil costs less than the same metal sold as sheets, with no intermediate cutting into formats.
• Less handling, less space: automatic feeding replaces loading and unloading, with no sheets to cut, palletize or move between machines.
  
  

Key features of coil-fed profiling

Precision comes from machine design: parallel rollers set the working depth on TRIS, CNC axes and CAD-CAM programming drive every bend on AC Bend. Flexibility comes from standard, interchangeable tooling. Continuity comes from automation: Produtech lines run without constant operator supervision, and since 2025 the AutoCOIL system changes coils automatically during production, removing one of the most laborious and dangerous manual operations, especially with thicker material.

Industries that use sheet metal profiling

Profiled sheet metal is everywhere a component has to combine rigidity with low weight. Produtech coil-fed lines work in Italy and abroad for:

• Construction: insulation, ducts, ventilation and air conditioning, metal frames, clean rooms and doors;
• Logistics: metal furniture and shelving;
• Storage: silos and tanks for food storage, roofs included;
• Metal containers: containers and electric cabinets;
• Other applications: electric motors, road signs, automotive, electrical appliances and subcontracted manufacturing.
  
  

Why choose Produtech: coil processing lines built in Italy

Founded in 1993 in Bergamo, Italy, Produtech builds sheet metal processing lines fed directly from the coil. Profiling machines complete this range:

• European quality and reliability: lines are designed and manufactured in Italy, with continuous investment in R&D and patented technology.
• Proven innovation: first coil-fed punching machines in 2002, first coil-fed fiber laser in 2011, EffiCOIL in 2018: still unique on the global market for its direct coil feed, with a Certificate of Excellence from the European Commission.
• Built around your parts: every line can be customised to your production needs.
• Support beyond delivery: customer support, training, maintenance and consulting, directly from Produtech.
