Pre-painted Galvalume Steel (PPGL)
The coating of pre painted galvalume steelis composed of 55% aluminium, 43.4% zinc and 1.6% trace elements.
PPGL is a product made of galvalume steel sheet. After surface pre-treatment like chemical degreasing and conversion treatment of galvalume metal, one or several layers of organic coatings are coated on the surface and then cured by baking. Also because there are various colors of organic coatings, color steel coil named after this, referred to as color coated coil or prepainted galvalume steel rollsheet. The color coated steel coilprice of the PPGL sheet is different according to the different patterns of pre painted coil steelyou choose.

Differences between PPGI and PPGL
PPGI is short for pre-painted galvanized steel, while PPGL is short for pre-painted galvalume steel. Compared with PPGL, PPGI has relatively active chemical properties, so its anti-corrosion ability is quite different. The test under the same outdoor conditions shows that the service life of PPGL is more than four times that of PPGI. The aluminium-zinc alloy structure of PPGL is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at 600 ℃. The whole structure is composed of aluminium iron silicon zinc to form a dense quaternary crystal, so as to form a strong barrier to effectively prevent the penetration of corrosion factors.
Aluminized zinc has a stronger protective effect and better corrosion resistance than galvanized products. The corrosion resistance of the "55% aluminium-zinc plated steel coil" comes from the barrier protection function of aluminium and the sacrificial protection function of zinc. When zinc makes sacrificial protection in the cutting, scratch and coating scratch parts, aluminium forms an insoluble oxide layer to play the function of barrier protection.
The heat resistance of 55% Al Zn alloy steel plate is better than that of galvanized steel plate, which is similar to that of PPGI. PPGL steel plate can be used in high-temperature environments up to 315 ℃.
55% Al Zn alloy plated steel plate has high reflectivity, making it a heat resistant barrier; The thermal reflectivity of PPGL is almost twice that of PPGI. Therefore, it can also achieve an energy-saving effect by acting as a roof and panel without painting.
Due to the excellent adhesion between the zinc layer of PPGL and the paint, when used as a signboard for general purposes, it can be painted without pretreatment and weathering treatment; PPGI needs weathering treatment and pretreatment. So that the surface of the PPGL sheet is smoother than that of the PPGI sheet.
