shot blasting
Essential for proper paint system adherence.

Impurities, oils, mill scale and rust on profiles are the root cause of 80% of all paint problems, such as flaking, cracking and rusting.

With SA 2.5 shot blasting we obtain an excellent degree of cleanliness and adherence of the SHOPPRIMER, which permits all manufacturing operations while keeping the base coat intact and enabling perfect adhesion of the following paint system coats.

We are reinventing the most common way of joining steel parts with innovative solutions

Welding procedures and operators are approved according to EN15609-1 and ISO 9606 respectively, in order to meet the quality requirements of the EN1090 Standard; working with Lincoln and Miller Mig welding equipment.

For reinforced beams, we have Saw welding, a Lincoln Twin-Arc H-Master line for automatic assembly and welding of widths of up to 1,500 mm and another Lincoln Jumo Frame line for special beams up to 3,000 mm wide. These lines are approved in accordance with EN15609 and ISO 14732.

Would you like to benefit from all the advantages of our approved procedures and welders?

reinforced beams
Jansa Metal was the first company in Spain to offer PRS welded reconstituted profiles.

Using 3 sheets (2 flanges + 1 web) we shape a beam into the desired size and form, joining and welding the sheets simultaneously with 2 submerged-arc welding beads on an automatic line with high current and voltage, obtaining a profile with perfect planimetry and symmetry.

By making an extra thickness penetration of 3.2 mm, we optimise the bead at the required strength.

We have two lines: an automatic JUWELD line for a large production of profiles up to 1,500 mm wide and a semi-automatic JUMO line for the production of curved beams or beams with cambers, box girders and special beams up to 3,000 mm wide.

Make the most of the great advantages offered by our Reinforced Beams.

We have one of the most efficient production processes on the market.

A Just in time production line concept: from the storage yard, each selected batch enters the JANSCOAT process via the infeed transfer and from there it travels along roller conveyors. We then move on in the next transfer to the cutting and drilling stations. Once this process has been completed, the batches are transferred to the next work stations. At the end of the chain, the parts are finished with Airless, paint, packaged and labelled in the shipping area.
