Office Supplies Metal Wire Binding Coil

Coil binding is a simple binding process that is used for a variety of different types of documents. It is not unusual for formal presentations and proposals to be constructed using a coil binding. This form of binding is also a popular option for cookbooks and instruction manuals. Printed materials that are joined using coil binding do not have a proper spine, as with books and other documents that are bound using other methods. However, coil binding does allow the document to lay perfectly flat when open.

There are a number of different names for the process of coil binding. Many booklets make use of what is known as spiral binding. These examples of coil binding make use of thin metal coils that are ran through a series of perforations along the top or left side of the document. The coils may be simple exposed metal types or the metal may be coated with a protective plastic cover that is available in many different colors.

How do I choose a spiral coil ?

We are a factory, you can contact me at any time to customize the binding coil that suits you, we provide a variety of binding coil sizes, if you are not sure about your size, not sure about the spacing? Here are the steps on how to choose the binding coil you need to buy.

1) Choose a Coil Size (Diameter) ?

If you want an alternative solution to choose the best size, you can utilize this general rule of thumb: 

1. Take the pages and covers being bound and lay the stack flat on a table.
2. Measure the thickness of the stack, but don’t press down; let it lay naturally loose.
3. Add 1/8" to the stack thickness - that will be the size of the binding coil recommended for your document thickness.

2) Select the coil spacing?

Spacing refers to the number of holes per inch or the spacing of holes. It's reflected in a ratio that includes the number of holes, a punctuation colon, and then an inch measurement. For example: 4:1. This ratio is read aloud/pronounced "four to one" and means 4 holes per 1 inch of length.

For example, in the United States, the standard pitch for helical coils is 4:1.

The 4:1 pitch bundled coil spine is by far the most popular, with approximately 98% of customers ordering the 4:1 pitch screw binder. 5:1 is a special pitch made primarily for print shops that have specialized equipment for punching patterns and users who may have machines made in other countries where 5:1 pitch is more common. Some more specialized machines will have other coil hole patterns such as 3:1, 2.5:1 or even 2.231mm. Before buying a screw binder, you'll want to check the compatibility of your screw binder, but keep in mind that most machines are 4:1.

3) Choose a Coil Color

Stock colors for most sizes and spacings include black, white, clear, royal blue, navy blue, red and silver. The colors are solid and uncoated, so they stay even with heavy use and scratching. Black coils are the most popular choice, with white and clear a close second. Maroons and navy blues are popular choices for professional agencies because they often match corporate branding. Red and royal blue are brighter and more vibrant than other colors and are therefore more common in schools and other organizations that require brighter coil bindings.

 We also have a large selection of special order colors that can be used to make your spines. Below are some of the most popular more unique colors.
