Pre-Painted Galvalume/ Galvanized steel coil – PPGL/ PPGI
PPGI/PPGL is also known as color-coated steel. This type of steel is galvanized or galvalume and then coated with a layer of color plating on the outside. This color plating, in addition to increasing the aesthetics of the project, also reduces the ability to absorb heat from the sun. Currently, PPGI/PPGL is often applied in many fields in many industries.

What is PPGI?
PPGI stands for pre-painted galvanized steel coil. This is a material produced from galvanized steel that is then coated with a layer of paint on the surface. PPGI coil is commonly used in construction, roofing, wall cladding, and many other applications due to its durability, corrosion resistance, and high aesthetic appeal

What is PPGL?
PPGL stands for pre-painted galvalume steel coil. Similar to PPGI steel coils, this material is produced by galvanizing steel and then coating it with a layer of paint on the surface. This material has better corrosion resistance than regular galvanized steel, and is commonly used in construction, roofing, and other applications due to its durability and aesthetics.
Therefore, in environments with harsh conditions and exposure to high salt concentrations, people often choose PPGL.
