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.
