Used for transport of air in ventilation systems. Air ducts (channels) are manufactured by means of automated processes from galvanized sheet steel coils, using specialized equipment that allowed us to evolve from the traditional manufacturing process and achieve high production efficiency and lower costs. Advantages: increased rigidity of the ducts due to “Z” shaped stiffening structure executed along the width of the sheet metal.
An important factor for the ventilation products is the lock seam. This type of folding leads to a great tightness, which has a positive impact on the systems operating costs.
