ALUMINIUM FRAME

NJL-S.A. has a unique team that ensures efficiency in all works involving the cutting and assembly of aluminum frames (doors, windows, facades).



CUTTING AND DRILLING

The cutting of the base material can be effected by mechanical or thermal processes. The mechanical process is performed by the Cutting and Drilling Center and the thermal cutting is performed by Plasma and Oxycut.



PICKLING

It is called pickling to the whole process on metal surfaces that aims at the removal of oxidations and inorganic impurities. There are several types of pickling, such as by abrasive blast (Steel Shot or certified sand) and Stainless Steel Pickling or Aluminum Pickling. Pickling in NJL-S.A. is made by projecting shot.



METALLIC STRUCTURE

NJL-S.A. works with semi-automatic welding (MIG/MAG) and with robotized welding (Welding Robot and Submerged Arc). All welding procedures and welders are certified by competent authorities.



ON-SITE ASSEMBLY

This area of activity requires prior coordination of all departments in order to assess the needs for the use of all equipment and materials suitable for the work, as well as all appropriate human resources.



PAINTING

All painters are qualified for various types of painting, and the most common technique in NJL-S.A. is the Airless projection.
