Perforated sheets

Meshes and filter components, sieves and all parts we produce can be made from a very wide range of materials, depending on the properties required and the environments in which they are used:

  • Breaking resistance
  • Deformability
  • Thermal and/or electrical conductivity
  • Machinability and weldability
  • Corrosion resistance (marine environment, acid, alkaline, adv.)
  • Thermal resistance
  • Food grade, aesthetics
  • Magnetic and electromagnetic properties

We can use the following materials to achieve this:

  • Stainless steels
    • Conventional stainless steels Aisi 304, 304 L, 316, 316 L, 316 TI
    • Stainless and special steels, magnetisable (430 adv.), refractory (321, Inconel adv.), duplex and super duplex (318LN, 1.4410), 317L, 330, Uranus, 904L, Incoloy, Monel, Hastelloy, adv.
    • Hyper-hardened stainless steels
  • Steels and coated steels
    • Annealed or high strength (HR) steel
    • Galvanised steel
    • Epoxy coating, rilsan coating
  • Non-ferrous metals and their alloys
    • Nickel, brass, aluminium, copper, titanium, gold
    • Cupro Nickel, Nitronic
  • Synthetics:
    • Polyamide
    • Polypropylene
    • Polyester
    • Polyethylene

Micro-perforated plates

Beyond the family of perforated plates of which minimum perforations are close to plate  thickness (approximately Ø1.00mm in 1mm thickness), it is possible to produce micro-perforated sheets with perforations of up to 25 to 40% of plate thickness (perforation of Ø 0.30mm in 1mm thickness), for very specific applications and using technical processes chosen according to the specifications.

The different shapes and layouts of the holes

  • Holes can be: Round, Square, hexagonal, slotted, rectangular and diamond.
  • Layout can be: staggered at 60°, aligned, alternating, staggered at 90°.
  • It is the combination of these 2 parameters that will specify the sheet, for example: R10T14, i.e. round holes Ø 10 mm staggered at 60° with a centre-to-centre distance of 14 mm, giving an open area of 46%.

Tôles micro-perforées

The following information is needed to specify your mesh and determine its price:

  • Raw material,
    • Stainless steel Aisi 304, 304 L, 316, 316 L, 316 TI
    • Stainless steel, magnetisable (430 adv.), refractory (321 adv.), super duplex (318 LN), adv.
    • Annealed or high strength (HR) steel
    • Galvanised steel
    • Nickel, brass, copper, gold, titanium, adv.
  • Holes shape and layout, for example: C3U5,
  • Sheet thickness,
  • Part dimensions quantity to be produced,
  • Solid border or not on one or more sides,
  • Required surface treatment and finish (degreasing, packaging, adv.),
  • Required certificates (material, dimensions, adv.)
