Our unique, exclusive own brands: Cintrex ®, Quatrex Fine ®, Swiss Gloss ® and Cronoline ® are specially designed for applications subject to strict requirements.

Cintrex ® welded bright precision tubes are unique for their constant high quality, where differences in dimensions, elongation and weld seam hight are much less from batch to batch than usual. Cintrex ® (with tolerances better than EN 10305-3) has been specially developped for bending on CNC machines. The internal weld seam is tightly specified and the tube offers constant high elongation values. Besides, special attention is paid to the tube surface, making it very suitable for wet lacquering. These tubes are often used to meet the strict dimensional requirements in the automotive industry, the furniture industry and the health care equipment industry.

Quatrex Fine ® welded square and rectangular bright precision tubes are unique for their constant high quality. Differences in corner radius, weld seam position and straight sides from batch to batch are much less than usual. Quatrex Fine ® (with tolerances better than EN 10305-5) has been specially developped for robotized processing. Because of the maximum internal weld seam hight of 0,5 mm and special attention for the tube surface, thise these tubes are often used for applications with strict requirements for telescoping.

Swiss Gloss ® welded precision tubes with tolerances better than EN 10305-3 and EN 10305-5 is our top product for the furniture industry. Through a high quality cold formed strip, special rolling procedure and further logistics handling, this tube can be chrome-plated with no further pretreatment. These tubes have the following distinctive advantages:

  • An ultra smooth surface (Ra max. 0,3 µ) making chrome-plating possible without previous grinding/polishing
  • With half (50%) of the dimensional EN tolerances on the internal diameter as well as a smaller weld seam, the tubes can be bent over a constant radius
  • A guaranteed high elongation value despite high tensile strength makes Swiss Gloss ® tubes ideal for bending very short radii.

Cronoline ® is a Cr6-free (environmental friendly) galvanized high pressure line pipe to EN 10305-4. Because of the constant quality of galvanizing, Cronoline is extremely resistant to corrosion. Quality and environment go hand in hand with Cronoline ® high pressure pipeline.
