Where one material is combined with another to protect the underlying structure by providing a coating or layer which is supposed to resist penetration of weather components or for aesthetic reasons, the process is called cladding. Cladding doesn’t actually require giving water-resistant situation, but rather control element which prevents direct water or wind from penetrating right into a structure. In cases where buildings exteriors covers don’t need to be fully sealed like train stations, bus stations and also car parks, the perforated steel cladding may be a better solution. There are several types of coating, for example, weather cladding, timber cladding, stone cladding, fiber, cement, concrete as well as brick cladding.
Several factors such as cost, manufacturing parameters, durability and also their appearance are considered when picking cladding materials. Although stainless steel and weathering steels are used in cladding, the most common materials used are steel and aluminum because they are metallic. Additionally, on numerous occasions, different metallic materials inclusive of copper, bronze and also titanium are used. Steel and aluminum are the most used although their difference is determined by strength, durability, and also their cost at times differ from all categories of metal cladding.
Aluminum is well known to resist corrosion because it reacts fast with oxygen to form a hard, dense coating which prevents further corrosion. Although aluminum has enough durability on it’s own, when used in the cladding, it’s durability is increased by adding organic and metallic components to form an alloy which include magnesium and manganese. However, matching the similar qualities of steel and aluminum can be a challenge, and in many instances, it depends on the specific conditions. Aluminum is usually more resistance against corrosion than metallic despite the fact that coated steel last longer. Also, aluminum is light in weight but not as strong as steel, hence profiles have to be deeper or thicker to extend the same distances between purlins. In manufacture of aluminum, large amounts of energy are used than in steel production which makes it to be more expensive than steel. Even though steel tends to perform better on the fire because it has a higher melting point, it is a bit more resistant against effect and moves less than aluminum when subjected to temperature changes. The strength of cladding metals depends mostly only on the power of the metallic materials used and also from their thickness. The thickness of the cladding is uniform all around the cross-section, and even the bond among the two metals is likewise uniform throughout. Copper and brass clad plate can be cut by use of powder cutting. Clad materials can be successfully welded by using special joint procedures to maintain uniform characteristic of clad components.
