Different Between Galvanized and Aluminium Roofing Sheet

What different between glavanized and aluminium roofing sheet? When it comes to roofing, there are a lot of choices to be made. One of the most important decisions is the material you use for your roof. Two common materials are galvanized steel and aluminum. Aluminum is a newer material and is becoming increasingly popular because it is lightweight, durable, and reflects heat better than steel. Galvanized steel is still the most common material used in roofing because it is less expensive than aluminum and has a long history of being used in construction. So, what is the difference between these two materials?

Galvanized Roofing Sheet

Galvanized Roofing Sheet is a popular choice for many homeowners because it is affordable and easy to install. It is also one of the most durable roofing materials available, with a lifespan of up to 40 years.
Galvanized roofing sheets are made from steel that has been coated in zinc, which protects the steel from corrosion. The zinc also gives the steel a shiny, silver finish.

Galvanized Characteristics

• Weather proof;
• Heating insulation;
• Fireproof; anti-rust;
• Sound insulation;
• Long life span: more than 20 years.

Aluminium Roofing Sheet

Aluminium roofing sheets are available in a variety of thicknesses, sizes and finishes. The most popular finish is mill finish, which is a natural silver colour. Other finishes include anodized (a clear or coloured coating), painted (usually white or black), and powder coated (a durable finish that is available in a variety of colours).

Aluminium Characteristics

• Aluminium roofing sheet are extremely light with high-strength-to-weight ratio.
• It often remains in working order with little maintenance for 40 years or more.

Difference between Galvanized and Aluminium Roofing Sheet

There are many differences between galvanized and aluminium roofing sheets. The most significant difference is in the material itself. Galvanized roofing sheets are made of steel, while aluminium roofing sheets are made of aluminium. This means that galvanized roofing sheets are much heavier than aluminium roofing sheets. Galvanized roofing sheets also have a much higher risk of rust and corrosion than aluminium roofing sheets.

Another key difference between galvanized and aluminium roofing sheets is in the way they are installed. Galvanized roofing sheets must be nailed or screwed into place, while aluminium roofing sheets can be install using specialised clips. This makes installation of galvanized roofing sheets much more time consuming and labour intensive than installation of aluminium roofing sheets.

Finally, the cost of galvanized and aluminium roofing sheets differs significantly. Galvanized steel roofing sheet costs significantly more than equivalent sized aluminium roofs because steel is a much more expensive material than aluminium.

Which one is better?

There are a few key differences between galvanized and aluminium roofing sheets. Galvanized roofing sheets are made of steel that has been coated with a layer of zinc. This makes them much more resistant to corrosion and rust than standard steel. Aluminium roofing sheets are made of aluminium that has been passed through a process called anodization. This gives the metal a much harder surface, making it more resistant to dents and scratches.

When it comes to price, galvanized roofing sheets are usually cheaper than aluminium ones. However, aluminium roofing sheets will last longer since they’re less likely to corrode or Rust.

So, which one is better? It really depends on your needs and budget. If you need a roof that will last for decades and can withstand all kinds of weather, then aluminium is the way to go. However, if you’re on a tight budget and need something that will still provide good protection for your home, then galvanized steel might be the better option.
