Bent section bars in aluminum and steel are used for the construction of the load-bearing portions of machinery with cabs.
We are specialized in bending and roll bending steel and aluminum section bars for the cabs of industrial machines like tractors, earth-moving equipment, cableways and electric cars.
A certified quality management system is essential to guarantee and maintain the company’s performance and value for our clients over the long term.
Tecnocurve is ISO 9001 quality certified by CSQ and since 2020 its production processes have been validated in accordance with UNI EN 1090.
When the time available is limited and there is a desire to avoid having to develop special equipment or projects that require small lots, our four special section bars for cabs are the ideal solution.
They are section bars in different metal alloys that are equipped with the rabbet for the window glass as well as the rabbet for the door of the cab. These section bars are available in our warehouse so as not to cause any delays for lead time.
Thanks to these 4 special section bars, we can complete the processing at even lower costs. In fact, the client won’t have to order special processing done ad hoc.
Bent section bars in aluminum and steel are mainly used in the construction of closed or semi-closed cabs. The cabs serve two functions:
These section bars are cold bent in accordance with the technical design specifications. They are usually used for the construction of the sides of the cab, but can also be used in other sectors (labeling machines, amusement park rides).
On these sections, the edging of the bar serves as rabbet for the door of the cab. This has two advantages:
Our bent section bars are used for the construction of cabs on the following machines:

Bent section bars for cabs can be either in aluminum or in steel.
Bent aluminum section bars are recommended for machines that dispose of very large cabs. Aluminum is a lightweight metal and its use contributes to reduce the total weight of the machine. In some cases, the geometrical design of the cab requires the use of aluminum rather than steel.
The construction of section bars for cab vehicles may include, depending on the type of cabin, specific processing requiring the use of different equipment.
The use of a bent section bar in cab construction offers a dual advantage:
With our latest generation tube bending machines, we are able to produce bent section bars with average fixed and variable bend radius.
The use of the laser-tube prior to bending the section bar allows us to produce holes, mitre cuts on the ends, slots, markings or micro-incisions on the section bar. Performing laser cutting procedures before bending (or roll bending) gives use two advantages:
Sometimes it is necessary to perform special processes on the section bar near the bent part. For these processes we use our innovative numerically controlled (CNC) work center.
They processes used include, in particular, the following:
