Rectangular metal expansion joints come in several different designs. Some of the designs that are commonly seen employed in industry are actually not recommended by expert manufacturers. Because of this, it's important to deal with a manufacturer that will give you accurate information on the durability and suitability of any option that you choose. Not all solutions are equally desirable.

Types of Rectangular Metal Expansion Joints

The single miter corner and double miter corner expansion joints are two of the most common and durable rectangular metal expansion joints in use. The single miter corner is more affordable and is used for numerous different applications. This design ensures that the rectangular metal expansion joints on which it is employed can handle a great deal of motion without failing. This is a simple type of corner to design and it results in a very durable and reliable product.

Stronger Pipe Design

The double miter corner design is suitable for applications where corner fatigue needs to be reduced. The corner fatigue is reduced by positioning the weld away from the centerline of the corner. This is a more complicated type of corner to produce and is more expensive than the single miter corner. It provides excellent service, however, and is suitable for a wide range of applications where the joint needs to be able to endure a wide range of motion without failing.

Flexonics, a Company that Knows

Senior Flexonics Pathway can produce rectangular metal expansion joints with single miter corner and double miter corner designs. One of the reasons you may want to consider this company is, even though they are very easy to produce and would theoretically be more profitable because of the lower production time involved, the company does not recommend using camera corners for any application. The company points out in its own literature that these types of rectangular metal expansion joints are easy for welders who have a low level of experience and skill to produce but do not provide the level of durability and performance required for demanding applications. This is a sure sign of a company that cares about the quality of the products that it delivers.

The different designs of rectangular metal expansion joints exhibit that the most convenient designs are not always the best. While they may be hard to produce for the fabricator, a single miter corner or a double miter corner are preferable for most applications.
