In composite cladding a metal which has thermal expansions coefficient less than 9 parts per million per degree centigrade is used. The temperature used for composite cladding is in the range of 20 degrees Celsius to 100 degrees Celsius. In this method the core material is clad using a transition metal or alloy. In composite cladding the cladding metal or alloy should at least cover one layer of the core. The most common use of composite cladding is for making walls and roofs using steel.
Profiled cladding or profile sheeting has been widely used for industrial buildings over the years. The metals used for profile sheeting are steel or aluminum. This type of cladding is mostly done for roofs and walls which need to be insulated. This type of cladding enables greater thermal movement and is resistant to corrosion. It has both durability and toughness and lasts over the years. The cladding is impervious and it does not allow water to seep in.
Cassette panel cladding is usually done in walls which are rectangular with formed edges. They are made from flat sheets of metals which form multiple layers that are pressed together to provide stiffness to the panels. This kind of metal cladding is also done by brake pressing. This involves folding flat metal sheets together. These sheets can be given additional stiffness by welding angle rails to the posterior of the panels. Certain factors on which the cassette panel cladding depends are the size of the metal panels used, the manufacturing requirements and limitations.
The most common and wide application of metal cladding is in manufacture of coins of various materials where an inexpensive metal is used as filler. This method should not be confused with electroplating, gluing, or welding as the principle and the method used in it is entirely different from them. Metal cladding is more durable and heavier than electroplating. Generally, there are three types of metal cladding: composite, profiled and cassette.
