It’s not that simple… or is it?

Regularly, we get calls or emails at Accurate Perforating requesting 10 sheets of pattern RS001 or other similar pattern numbers from our patterns page.  Unfortunately, it’s not that simple.  The pattern number is just a piece of the information needed to specify perforated metals, not a finished product in itself.  On the other hand, it’s not really that complicated either.  The RS001 reference number, like all the pattern numbers, specifies several selection criteria, including hole size and shape (round, slot, decorative, etc.), the distance from the center of a hole to the adjacent hole (centers), and the orientation of the pattern (straight or staggered).  These factors combine to determine the “Open Area” of a pattern.  The open area is, quite simply, the percentage of the total surface area of the part that is open compared to the solid metal area.  This is a critical factor in many applications of perforated metal and something to be discussed in future entries.

So those are the basics regarding the pattern numbers.  But that is just the beginning.  When selecting perforated metals you also need to select the material.  Accurate has experience perforating practically every common type of metal and even some not-so-common types.  Once the material type and thickness (gauge) are selected, consideration should be given to material finish such as mill finish or mirror.  This is usually determined by the final processing or application of the material. 

And now it’s time to apply the perforation pattern.  But wait there are a couple more options to consider.  The last two key factors are end patterns and margins.  End patterns refer to the symmetry or the lack of symmetry as it pertains to the lead edge of the pattern and the tail edge of the sheet as it goes through processing.  There are three standard end patterns: unfinished, finished, and symmetrical.  Examples of these can be found on our website.  A margin refers to a solid section of metal in or around the perforated material.  Options range from no margins to custom width edge margins through internal margins. Examples of each can be found on our website.

So there you have it.  It may seem like a lot of factors to consider, but there is a method to the madness.  And remember our product specialists are always here to answer your questions and talk you through the not-so-simple selection process. 

Let Accurate Perforating help, it’s just that simple.

Mail Call

I recently received an envelope in the mail. It was rather plain and lacked much excitement. Yet it was intriguing in the sense that I was not sure what it contained. It was addressed to me personally and resembled a letter someone would receive at overnight camp. I studied the envelope for a minute or so and then opened it up. Inside, was nothing more than a junk marketing letter from a magazine we once advertised in years back. I studied it a little longer, admired the personalization of the message and then tossed it into the garbage. The entire process from letter in hand to garbage can lasted about 45 seconds.

Later that day, I received an email from another industry trade publication with the subject “One-Day remaining to advertise.” Faster than I could ever dream of throwing something in the trash, this email was quickly placed into my virtual trash bin.

I remember the name of the publication company that sent the direct mail. I even remember exactly what the envelope looked like.  On the other hand, I don’t even remember who the email came from and what the body of it said if anything at all. In fact, I never saw the body of the message. In a time of oversaturated cluttered online marketing, are we at the point where “old-fashion” direct marketing is more impactful?

Of course, direct snail mail is more expensive and uses more resources than shooting off an email blast. But consider the impression it leaves on the potential consumer. Also, consider the level of distraction the receiver has when they receive an email as opposed to their concentration level or better yet their lack of distraction when it arrives as paper mail. When a junk email arrives it sometimes never even reaches the inbox but rather it goes directly into their spam folder. At least with regular mail, some effort and involvement is required to discard it.

“Marketing messages should target customers at times when they are unoccupied, perhaps even actively seeking some sort of information to process. Consider, for example, an airplane on the landing path into an airport. Sitting upright, with in-flight entertainment and electronic devices switched off, passengers have little to do but to look out of the window and wait for the aircraft to land.” (

And that article was written nearly four years ago. So are we at the point where opening the ominous looking letter, albeit the same message as the email, is now not only the road less traveled, but also now the preferred one?
