Metal cladding refers to a protective coating, involving the use of heat and/or pressure to bond material such as metal powder or foil to a surface. In addition to being very reliable and cost-effective, metal cladding also offers corrosion and wear protection. A range of critical applications in various critical metals and composites can be optimized by adjusting the process parameters.
Generally, there are four main types of metal used for metal cladding:
- Steel: All steel is relatively affordable, but it’s not as durable as other materials. For a robust finish, we usually galvanize them hot-drip.
- Alloy: An alloy made of aluminum is very lightweight, as well as corrosion-resistant.
- Zins: In untreated form, zinc weathers into an aesthetically appealing lead-like hue.
- Copper: Copper is a metal that has a long shelf life and does not require much maintenance.
Cladding process includes the following steps;
A roll bonding process uses a pair of rollers to thoroughly clean and bond two or more layers of metals. Metals are deformed and the thickness of the clad material is reduced when high pressure is applied. Metals that are not ductile enough may need to be heated.
Explosive welding involves using a sheet of chemical explosive to apply pressure between two layers. The bond between metals does not produce a heat-affected zone.
It is a method of transferring material to a substrate via the use of a laser after powdered or wire feedstock material has been melted and consolidated (additive manufacturing technology)
Cladding offers the advantage of flexibility since the materials and processes can be tailored to the specific job requirements.
Ceramic and metallic coatings can be applied using laser beam cladding. As a result, these cases require effective cooling, which means a smaller area is affected by thermal fluctuations. Surfaces can be made wear-resistant by cladding with metal. Complex shapes can also be used with the method.
The most common and advantageous cladding material is metal, but there can be wood, plastic, stone, or imitation stone. Its benefits are becoming increasingly recognised as aluminium or steel cladding panels expand in popularity.
Protection and Strength.
The cladding protects the structure and aesthetics of a building from various elements such as wind, high temperatures, water absorption, sunlight, and pollution.
Materials that are made of metal are considered non-combustible in the International Building Code. However, it does recognize that metal-clad buildings are significantly safer than wood-clad buildings due to their noncombustibility.
Metal cladding panels do not require as much maintenance or repair as wood, stone, or painted surfaces. For the retention of its good aesthetics, metal cladding can be simply cleaned to protect it against harsh weather conditions.
Panels made of metal provide the lightest cladding option, especially when they have light, aluminium honeycomb cores. As a result, dead loads are not increased, and they are easily transported and installed.
A building’s appearance can be dramatically changed by metal cladding, making it more appealing and adding value. A variety of metal cladding styles and finishes are available, including sleek stainless steel, rustic metal looks and many other options.
The use of recycled materials in metal cladding reduces the amount of waste sent to landfills since the material can be recycled.
