As carbon steel is not resistant to corrosion, it must be painted or galvanized for protection. The raw material is processed by either cold rolling or hot rolling, both of which affect the properties of the product. Cold rolling provides better surface conditions with lower tolerances.

Aluminum is a durable, elastic, and stain-resistant metal that is 100% recyclable and environmentally friendly. It allows for a variety of surface treatments that provide different colors, patterns, and textures. Some of the recommended aluminum alloys are 1050, 3003, and 5005. Aluminum is preferred for its weight advantage, making it a popular choice for building materials.

Stainless steel is a steel alloy with added chromium, nickel, and sometimes molybdenum or other elements. It is resistant to corrosion, wear, and all types of weather conditions. Stainless steel has a distinctive appearance and high level of durability that allows it to be used as thin panels. Some popular alloys of stainless steel include 304, 316, 316L, and 430.

Corten steel is a group of steel alloys with added copper, chromium, nickel, and phosphorus. When exposed to the atmosphere, Corten steel forms a protective layer of rust, which gives the material its unique texture and color and makes it resistant to weather conditions. It is often preferred by architects, designers, and artists for its aesthetic qualities.

Copper is a noted for its bright red hue, lightweight and durable. It is resistant to corrosion and wear. Copper is also a good conductor of heat and electricity, and has antimicrobial properties. Copper weathers to a variety of unique and authentic appearances depending on the surrounding temperature and humidity levels.

Titanium zinc is a zinc alloy that is 99.995% zinc and 0.003% titanium. It is more durable than brittle zinc. The patina that forms on the surface of titanium zinc reduces its interaction with the elements in the air, protecting the surface from weather conditions. Its malleable texture makes it a popular choice for curved surfaces. Some recommended alloys of titanium zinc are C28000 and C22000.

Brass is an alloy of copper and zinc, with an appearance similar to shiny gold. It is resistant to corrosion and wear, and is also a good conductor of heat and electricity. Brass is a popular choice for decorative purposes, and can be found in a variety of items such as doorknobs, plumbing fixtures, and musical instruments.

The composite panels consisting of polyethylene or mineral filled core between two aluminum cladding sheets.

Pre-Galvanizing is also known as the mill galvanizing. The advantage of this method is that coils of steel sheet can be rapidly galvanized on a large scale with a uniform coating and provides corrosion resistance.
