Wire-O Binding

Wire-O binding has many names: double-ring, double-O, double-wire, and double-ring binding. This method uses a continuous hinge of double wire loops to hold the book cover and pages together. Graphic designers prefer this method as it offers stylish metallic finishes in a variety of colors. This traditional method of wire binding protects the pages so they cannot be modified without unwrapping the book. Books bound using the Wire-O method tend to lay flat and the paper can be rotated 360°, making it ideal for calendars or notebooks.

For businesses that need to produce professional-quality books, Wire-O binding is the best solution. This binding offers a clean and classy appeal unmatched by any other traditional binding method. Our selection of Wire-O binding supplies includes a range of spacing options and color varieties of double loop wire barbs. The 3:1 pitch Wire-O is available in sizes from 1/4" to 5/8", which means it can be used for books ranging from 2 to 130 pages in size. 2:1 pitch Wire-O is typically available in larger sizes from 5/8" to 1 -3/4", ideal for books ranging in size from 135 to 320 pages, but we also offer a unique full range of 2:1 wire sizes , which provides more functionality.

Our selection of Wire-O bookbinding supplies includes wire calendar hangers and manual thumb cut punches, making it easy for everyone to make. The gold-plated coating can meet the higher requirements for binding. Its biggest feature is that it is very bright and flashing, dazzling, and rich in color.

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)Select Wire-O binding size (diameter)?
Now select your Wire-O binding size (diameter) for your document. You can use the coil binding capacity chart below to help choose the best size for your stack thickness or paper capacity. Please note that paper capacity is calculated using all 20 lb bond copy paper sheets (not pages) without any covers; this means it may vary greatly depending on the stock you use, this is our recommended stack thickness reason for the method. Remember: slightly larger coils are better than too small coils; small coils won't turn the pages smoothly and will pinch them, making them more prone to tearing. Therefore, if your size is between two sizes, we recommend that you size up.

3) How to choose Wire-O binding length?

3:1 spacing, hole spacing 8.46mm, 2:1 spacing, hole spacing 12.7mm. We use a simple method to calculate the matching Wire-O staple length,
Remember that the margins around the edge of the book must be around 5mm, do remember that you need a 3:1 or 2:1 spacing?
We simply subtract 5mm from its total binding length and divide by the 8.46mm or 12.7mm spacing, and the result is the length of the Wire-O binding,
