The building expansion joint Cover, also known as an EJC, gives a covered transition between two Expansion Joint surfaces, staying unaffected by both the relative motion of both surfaces either side of it. Expansion joints are those joints that allow a solid object to be bent (extended) without the bending action causing undue stress on the adjacent surfaces. An EJC also ensures that the object is not damaged while in motion and that it can withstand high loads for long periods of time. It also provides maximum protection against wear and tear by being able to provide a seal with an interlock design. The seismic joints are generally used in the automotive industry as they are extremely rigid and durable, especially when compared with the conventional rubber material which is brittle in nature and can crack under extreme pressure. The flexible nature of EJCs allows them to be used in other industries, like aerospace applications, in which they are essential for ensuring the stability of the objects to be attached. As opposed to rubber EJCs, EJs are made from a special polyurethane substance. A high-quality EJC is designed to resist moisture, and will also offer resistance to impacts. The polyurethane sealant used in the EJCs ensures that the seal remains strong for a long time. Another great feature of EJCs is that they come in a wide range of colors, sizes and thicknesses, which enables you to choose the best one for your specific application. All types of EJs are designed to work well together, ensuring that each EJC is perfectly compatible with the other. You can purchase EJCs from any local hardware store. However, if you're looking for a good quality one at an affordable price, you should look online. Online stores offer a wide range of EJCs at much lower prices. Most online stores will ship their EJCs to your house for free, saving you even more money than buying it from a hardware store. If you have no experience with EJCs, it's always advisable to consult an expert to get the best ones for your use. The more experience you have with them, the easier it will be for you to install them correctly and ensure that your EJC is installed correctly. If you decide to install your EJCs yourself, remember to follow the directions carefully so that your installation does not pose any risk to your object. You may also want to install some extra seals, such as an EJI sealant, in the gaps around your expansion joints to ensure that they stay well together. While purchasing EJCs, you will be presented with a variety of different models, depending on the materials that they're made from. Some of these materials can be highly effective at resisting heat and moisture, while others may not be as effective.
