Types of Ties

Reinforcement tie wire is made of annealed wire for reinforcing steel, and there are various sizes of tie wire for concrete reinforcement for choice. Tie wire is popularly used in the daily life and various industries for binding, tying, fencing and other industrial uses to avoid frequent and repeated maintenance. 

1. Snap tie or simple tie - simply wrapped once around the two crossing bars in a diagonal manner with the two ends on top. These are twisted together with a pair of side cutters until they are very tight against the bars. Then ends of the wire are cut off this is used mostly on floor slabs.

2. Snap tie with a round or wall tie - This tie is made by going about 1 1/2 times around the vertical bar, then diagonally around the intersection, twisting the two ends together until the connection is tight, but without breaking the tie wire, then cutting of the excess. The wall tie is used on light vertical mats of steel.

3. Double-strand simple tie - this tie is a variation of the simple tie. It is especially favored for heavy work.

4.  Saddle or U tie - the wire pass halfway around one of the bars on either side of the crossing bar and are bought squarely or diagonally around the crossing bar with the ends twisted together and cut off. This tie is used on special location such as wall.

5. Saddle or U tie with a twist - this tie is a variation of the saddle tie. The tie wire is carried completely around one of the bars, then squarely across and halfway around the other, either side of the crossing bars, and finally brought together and twisted either side of the crossing bars, and finally brought together and twisted either squarely or diagonally across. The saddle tie with twist is used for heavy mats that are to be lifted by a crane.

6. Cross tie or figure eight tie - this type of tie has the advantage of causing little or no twist in the bars.
