For example, if a QR Code symbol is printed with a 600 dpi, 4-dot printer, the module size is 0.17mm. A scanner resolution of less than 0.17mm is required to read the symbol. Small printing in the limited area with a higher head density printer can be useless if the reading limit of the scanner is exceeded. Extra Wide Chrome Body Side Molding is created using 3-Step method, using 2 inch, 1 inch and 3/8 inch chrome moldings. Build up using widest molding at bottom and narrow at the top. Separate rolls allows flexibility of design- eliminate one roll if you prefer a shorter width (e.g. 2 3/4 inch molding or 3 3/8 inch.
In my previous post, What Size Should A Printed QR Code Be, I mentioned that it wasn’t the size of the QR code image that determined the minimum size at which a QR code could be scanned, it was actually the size of the modules (the little black squares) that make up the QR code image. If the size of the modules fall below the resolution limit of the camera then the QR code won’t be able to be read by the device.
A fundamental part of the way QR codes work is that the more data you put into them, the more rows and columns of modules will be introduced into the QR code to compensate for the increased data load. Hence, for a QR code image of a certain size (width), the more data it contains, the more rows and columns of modules it has and, logically, the smaller each of the modules then become as a result.
So it’s all about whether the camera can actually “see” the smallest element in the QR image – the individual modules.
Another factor that influences minimum QR code size is the scanning distance – the distance the phone is held away from the QR code image. The further away the QR code is, the smaller it appears in the camera viewport, and so the smaller the modules will appear too. Once again, if the camera is held too far away, the modules become too small for the camera to read and the QR code won’t work.
The following table shows the theoretical minimum width of a printed QR code image for a given scanning distance, based on the minimum size an individual module needs to be when viewed by the camera. The assumptions here are that an 3-4 megapixel camera is being used (lower resolution cameras would need the QR code image to be even larger to “see” it), and a black QR code on a white background is being used.
The data shown is:
- Modules: Number of rows and columns of little black squares in the QR code image.
- Characters: Approximate number of characters that would normally fit into a QR code with that many modules using binary data encoding (most do) and Level L error correction.
- Scan Distance: The distance the camera is being held away from the printed QR code.
So for instance, a QR code image with 72 characters of data would end up with 35 rows and columns of modules, and would need to be 42mm (1.7″) wide to be successfully scanned from 300mm (12″) away, but only 21mm (0.8″) wide if the scanning device was only 150mm (6″) away.

100 | 739 | 60mm (2.4″) | 120mm (4.7″) | 182mm (7.2″) |
Here’s a few examples to give you an idea of what QR codes look like as their data load gets higher, resulting in the modules getting smaller and the QR code image becoming more dense.

Corrugated Metal Sheet Sizes
1-1/4' x 1/4' Corrugated Panel
The 1-1/4' corrugated panels primarily come in a galvanized finish, and in lighter gauges. (26-28-29 gauge). This panel has the slightest of the profiles and is used in both decorative & and industrial applications. We can only make this panel profile in almost any material. Please inquire about other finishes such as aluminum & stainless steel. The standard galvanized sheet would come in a standard 26' wide sheet, with lengths of 8′, 10′, & 12′ long.
2-1/2' x 1/2' Corrugated
The 2-1/2” x ½” corrugated sheet metal is probably the most common corrugated panel on the market today, and has been used as the standard“ corrugated” for many years now. The 2-1/2” corrugated is typically used for the “pole-barn” and almost simple corrugated structure. Keep it 1 3. The 2-1/2” dimension denotes the distance from the peak of one ‘bump to the peak of the next, and has an overall height of ½”.We typically stock and sell this in the (G-90) galvanized finish as our standard stocking item, but can provide this is any material you require, such as a plain steel, fiberglass, aluminum (smooth & stucco embossed) as well a painted finish and stainless steel, in both the (T-304) & (T316) materials. Our stocking sheets are all galvanized ::

Other finishes will have varying widths, so please inquire as to which width is the standard for each material type. We also have started offering the 2-1/2” x ½” in a corrugated & perforated panel which is very unique, which we can do almost any hole pattern with. The 2-1/2” x ½” corrugated panel profile is certainly the most common and most versatile panel on them market today and can be used in any application you may need. Please call Corrugated Metal (215-860-3600) with any size inquiry, 1-2 sheets or 1,000 to 2,000 sheets and we can ship directly from our stock sheets. Also, inquire about whatever finish or material you may need and our sales staff will more then happy to customize your quote and material to fit your needs.
(2.67' x 7/8') Corrugated :
The 2.67′ x 7/8' corrugated profile offers a deep groove for a more pronounced corrugated style. This deeper groove offers a stronger overall panel in any gauge thickness, and allow for a larger span. The 7/8' corrugated is offer in both the galvalume and aluminum materials in standard lengths of 8′,10′, & 12′ long. The typical material thickness offered are either 18-20-22-or-24 gauge. The corrugated with this 2.67' spacing is very widely used in many roofing applications with it’s deep grooving allows more run off of water, and gives an overall S-Style that has the look many people are after. We can offer this panel in stainless steel, but we would typically stock in either a plain galvalume material or the aluminum mill finish, with the smooth or stucco-embossed finish. We also spec. this panel with a large number of our perforated & panel requests. We can also quote this material in a painted finish as well. Please call Corrugated Metal with your inquiry and our knowledgeable staff will more then happy to help you with your order, or material quotation.
2-6/7'x3/4' Corrugated
The 2.67′ x 3/4' corrugated profile offers a deep groove for a more pronounced corrugated style. This deeper groove offers a stronger overall panel in any gauge thickness, and allow for a larger span. The 3/4' corrugated is offer in both the galvalume and aluminum materials in standard lengths of 8′,10′, & 12′ long. The typical material thickness offered are either 18-20-22-or-24 gauge.

4.2' Corrugated
(4.2 panel shown, top to bottom, Galvanized, Bronze-Painted, Aluminum (stucco-embossed) and Kynar painted Beige)
The 4.2 corrugated panel is a high profile, wavy style panel that is used and can be used in almost any roofing, siding, or decorative application. The (4.2) panel groove is similar to the standard 2-1/2' corrugated and based on the same premise but with bigger more pronounced look. Originally this profile was made in a concrete version and used as an asbestos replacement panel, it is now used in the industry for many others applications where a corrugated look is wanted. The 4.2-Inches denote the distance from one peak to the next peak and has an overall height of 1-1/16' if were laying flat on the ground, this is deepest 'wavy' style of corrugated available anywhere.
The 4.2 Profile is the preferred choice in many applications where a traditional 'corrugated' will work but not look as good, or have the strength of this panel. Not many companies in the country even carry the 4.2 wavy style of corrugated, so look no further since, we also stock this and can make it practically in any material our customers can imagine. Below, are stock sizes, but almost anything can be done in a plain-steel or the standard galvanized. We can also, offer this in a painted version, or stainless steel (both T304 & T316, and in 2-B & #4 finishes), and in aluminum with a mill (smooth) finish, or the Stucco-Embossed (pebble finish). Now offering the 4.2 panel in lengths up to 40′ long. We are also the first offer this in a perforated and corrugated panel which is one the top choices by architects and designers. Please call Corrugated Metal and explore all the possibilities when using the (4.2) Corrugated Roofing/ Siding panel.
