Aluminum sheet   is a flat, thin piece of aluminum that is produced through various manufacturing processes such as rolling or extrusion. It is available in different thicknesses, widths, and lengths to suit different application requirements. Aluminum sheets are widely used in industries that demand lightweight, durable, and corrosion-resistant materials. Properties of Aluminum Sheet Aluminum sheet exhibits several desirable properties that contribute to its popularity: Lightweight: Aluminum is known for its low density, making aluminum sheet significantly lighter than many other metals. This property is particularly advantageous in applications where weight reduction is crucial, such as transportation vehicles. Corrosion Resistance: Aluminum has a natural oxide layer that forms on its surface, providing excellent corrosion resistance. This makes aluminum sheet highly resistant to rust and other forms of corrosion, ensuring its longevity and durability. High Strength: Although aluminu

Pre-painted galvanised iron steel (also known as PPGI) and   pre-painted aluminium galvanised steel  (PPGL) are two different types of colour coated steel. both PPGI and PPGL are used in a wide range of industries such as construction, transport and the appliance industry. They are both very similar, but still have unique differences.   Different types of substrates Galvanised steel PPGI is completely coated with zinc, while galvanised steel PPGL is coated with aluminium, zinc and a small amount of silicone. This provides superior corrosion resistance and durability compared to typical galvanised coatings. This is the biggest difference between PPGI steel and PPGL and is responsible for many of the differences in weight, product life, appearance, price, application and other characteristics.   Weight difference between PPGI and PPGL As the specific gravity of aluminium is less than that of zinc, the aluminium-zinc coating on PPGL will be lighter for the same coating thickness.
