Crown Staples

    2. Wide Crown Staples
      Crown staple is classified by length of crown, the part across the staple top, since the pneumatic guns used for driving staples will be different as crown size varies. For example, 413J pneumatic staple means 4mm-wide crown and 13mm-long staple leg. N, K, and other staple series are also available. Wide crown staple is applicable in sofa construction, wooden furniture building, ceiling framing, wood panel fastening, as well as other construction jobs.
    2. Medium Crown Staples
      Medium crown staple is normally made from galvanized wire. It comes with a wide range of specifications and packing methods that designed for users' specific applications. Featuring rigid structure and excellent finish, crown staple has found applications in extensive fields, like in cedarwood working, shingle roofing, subflooring, wall sheathing, roof decking, metal sliding, composite sliding, wood fencing, and furniture construction, just to name a few.
    2. Narrow Crown Staples
      Crown staple, generally made from galvanized wire, shares a similar structure with book binding staple. Models of narrow crown staple normally start with J. It is a kind of pneumatic staple. Typical applications are found in house building, interior decoration, furniture construction, wooden box packaging, leather repairing, and shoe manufacturing, etc.

Staples generally come in a same structure: simply a formed metal wire bent into a very precise U-shape. It comprises 3 parts: the crown, the legs, and the point.

The part across the top is called the crown. It determines what will drive the fastening tool as different tools require different crown sizes.

The 2 legs are parallel and are designed to penetrate into materials. Length of the leg varies as the application changes. Each tool will generally drive a range of different lengths.

Tip of each leg is known as the point. They normally come as chisel points, with high holding power needed. The points may be divergent. Besides, they have been specially treated to guide the legs in a curve rather than straight down into materials. It would be much harder to pull the staple out if the legs are not parallel.

Crown staples can be coated with different materials. Typical examples are stainless steel staples and galvanized steel staples.
