PPGL Pre-Painted Galvalume Steel Coils/Sheet
Product introduction of Color Coated Steel Coils
PPGI & PPGL (prepainted galvanized steel & prepainted galvalume steel) also known as pre-coated steel or color coated steel coils,
They are use hot-dip galvanized sheets, hot-dip galvalume sheets, electro-galvanized sheets, etc. as substrates. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coatings are coated on the surface, and then A product that is baked and solidified. Colored steel coils are named after being coated with organic coatings of various colors, referred to as color-coated coils.
Substrate Type of Color Coated Steel Coils/Sheet
1.PPGI-Hot-dip galvanized color coated steel sheet(prepainted galvanized steel sheet)
The product obtained by coating an organic coating on a hot-dip galvanized steel sheet is a hot-dip galvanized color-coated plate. In addition to the protective effect of zinc, the hot-dip galvanized color-coated sheet also protects against rust and has a longer service life than hot-dip galvanized sheet;
2.PPGL-Hot-dip aluminum-zinc color coated sheet(prepainted galvalume steel sheet)
Hot-dip aluminum-zinc steel sheets can also be used as color-coated substrates (55% AI-Zn and 5% AI-Zn)
PPGL steel is a durable, colorful, and economical building material. It is the abbreviation for pre-painted galvalume steel, which is with Al-Zn coated steel sheet substrate. Then the Al-Zn coated steel is painted continuously in coil form. Because of its excellent heat and corrosion resistance, it has become the preferred material for a wide range of construction uses, particularly roofing and walling.
3.Electro plated zinc color coated sheet
The electro-galvanized sheet is used as the substrate, and the product obtained by baking with the organic coating is
an electrogalvanized color-coated plate. It has a beautiful appearance and excellent processing properties, and
therefore can be mainly used for home appliances, audio, steel furniture, interior decoration, and the like.
The Coating Type for PPGI/PPGL Color Coated Steel Coils& Sheet
Polyester (PE): Good adhesion, rich colors, wide range in formability and outdoor durability, medium chemical
resistance, and low cost.
Silicon modified polyester(SMP): Good abrasion resistance and heat resistance, as well as good external durability
and chalking resistance, gloss retention, general flexibility, and medium cost.
High Durability Polyester(HDP): Excellent color retention and anti-ultraviolet performance, excellent outdoor durability and anti-pulverization, good paint film adhesion, rich color, excellent cost performance.
Polyvinylidene Fluoride(PVDF): Excellent color retention and UV resistance, excellent outdoor durability and chalking
resistance,excellent solvent resistance, good moldability, stain resistance, limited color, and high cost.
Application of PPGI/PPGL Color Coated Steel Coils& Sheet
Construction: Roofs, Walls, Garages, Acoustic Walls, Plumbing and Modular Houses, etc.
Automotive: mufflers, exhaust pipes, wiper attachments, fuel tanks, truck boxes, etc.
Home appliances: refrigerator back panel, gas stove, air conditioner, electronic microwave oven, LCD frame,
CRT explosion-proofbelt, LED backlight, electrical cabinet, etc.
Agricultural use: pig house, chicken house, granary, greenhouse pipes, etc.
Others: Thermal insulation cover, heat exchanger, dryer, water heater, etc.
