Manufacturing process

  • Sheets are perforated in stamping machines. Standard dimensions of perforated sheets are 1,000 x 2,000 mm with maximum dimensions of 1,500 x 3,000 mm in accordance with the used tool. In case of large-volume orders, certain perforation types may be realized in coils with width 1,000 mm, 1,250 mm and 1,500 mm. Holes are done using simple stamps (for thick sheets or for special perforation types) or combination ones or perforation all across the sheet width.
  • High-pressure stamping machines can be divided into several types enabling perforation of mild steel sheets up to a thickness of 12 mm and stainless steel sheets up to thickness of 8 mm.
  • Perforation is done by laser for sheets with thickness in excess of 12 mm.

Materiál

  • We are able to perforate all metallic materials.
  • Other non-brittle materials (e.g. plastics) may be perforated by agreement as well.

Application

  • ventilation equipment
  • acoustic purposes (application for noise suppression, noise protection panels and/or walls etc.)
  • filters, filtering baskets etc.
  • covers (in all technical branches not only for safety purposes but also for decoration etc.)
  • architectural elements ( building facades, decorative suspended ceilings, gratings, reinforcements, grids, ventilation covers, decorative partition walls etc.)
  • sieves (sorting boards for agriculture and other industiries)
  • conveyor belts for particularly severe operating conditions
  • cable trays for electric distribution systems
  • baking tins for bakers and confectioners
  • metallic seats made from perforated sheet for sporting halls and/or stadiums etc.
  • plaster and heat insulation profiles
  • other products from perforated sheet as required by the customers
