Cost Influences for Slip Resistant Stainless Perforated Sheet

September 19, 2012

Stainless perforated sheet cost can differ based on a number of variables. Review this checklist to consider how your projects needs will affect your budget then continue to our how-to pages to learn how to order perforated metal. Review the following as you consider your next perforated application:

  • The material type has been selected for the project’s requirements.
    • Remember the least expensive material may not be the lowest cost; a higher strength alloy may allow reducing thickness.
  • Material thickness has been determined.
    • Thinner materials perforate with ease and faster.
  • Hole shape and pattern are selected.
    • Round holes are the most economical.
    • 60” staggered hole pattern is the strongest and most versatile.
  • Hole size is considered with regard to the following:
    • Do not go below a 1:1 ratio to the sheet thickness.
    • Stay at 2:1 or larger if possible for a higher performance and strength integrity.
  • Bar size observes the requirements.
    • Do not specify thinner than a 1:1 ratio with sheet thickness.
  • Center distance meets design needs and is conscious of production.
    • Controls the feed & production rate respectively, if possible, choose a pattern with a longer center distance to maximize production.
  • Specify open area proportion.
    • Extreme open area proportions increase distortion, if possible, stay under 70%
  • Margins are specified for ease of production and to prevent distortion.
    • Keep side margins to a minimum.
    • Use standard unfinished edge margins whenever possible.
  • Consider die pattern for blank areas.
    • For custom  patterns this is especially important, it can change the appearance of the aesthetic across the sheet; it is best to consult with your material supplier.
  • Determine if the environment will require slip resistance.
    • In locations where water, oil, grease, or other factors create slippery conditions consider maximizing the safety of your perforated metal by also specifying the SlipNOT® surface.
    • Specify standard patterns, dimensions, and tolerances whenever possible.When in doubt, stick to standards.
  • Before specifying a custom or special, consult with your supplier; it may be possible to use existing tooling to meet your projects needs.
