Prepainted Galvalume SteelPrime

 Overview

PPGI is pre-painted galvanised iron, also known as pre-coated steel, coil coated steel, color coated steel etc., typically with a hot dip zinc coated steel substrate.The term is an extension of GI which is a traditional abbreviation for Galvanized Iron. Today the term GI typically refers to essentially pure zinc (>99%) continuously hot dip coated steel, as opposed to batch dip processes. PPGI refers to factory pre-painted zinc coated steel, where the steel is painted before forming, as opposed to post painting which occurs after forming.

Galvalume Steel:alloy protection, long-term protection
With 55% aluminum, 43.4% zinc and 1.6% silicon alloy coating composed of gold ratio, a three-dimensional protection system was constructed by molecular structure optimization. In the salt spray filled coastal areas, acid rain frequent industrial heavy pollution areas, its corrosion resistance life can reach 2-4 times of the traditional galvanized steel plate; In the face of 250℃ high temperature environment, it can still maintain stable mechanical properties. From the metal roofing of skyscrapers to the precision housing of smart appliances, it redefines the durability standard with its ability to withstand protection.

Galvanized Steel:the classic heritage, the all-around choice
After hundreds of years of verification of galvanized steel, through hot dip galvanizing or electric galvanizing process, the formation of dense zinc shield on the steel surface. When the zinc layer is damaged by scratches, the unique "sacrificial anode protection" mechanism automatically activates, continuously defending the matrix like a warrior in armor. With its cost advantages and excellent stamping and welding performance, it has become the cornerstone material for construction scaffolding, automobile chassis, civil furniture and other fields, and has built an industrial foundation with reliable quality.

Aluminum Coil:Light and flexible, infinite possibilities
Selected 99.7% high purity aluminum ingots, through 28 precision rolling processes, to create both aviation strength and silk-like malleability of aluminum rolls. Its density is only 1/3 of steel, but it can withstand the tensile strength of more than 500MPa, and with 12 kinds of surface treatment processes such as anodizing and fluorocarbon spraying, it can achieve 200 + kinds of visual effects such as mirror, frosted and wood grain. From the streamlined facade of the Burj Al Arab Hotel in Dubai to the food-grade aluminum foil packaging, it carries unlimited creativity in a light manner.

Stainless Steel:luxury texture, technology crystallization
The fusion of 8% nickel and 18% chromium gold ratio, through vacuum melting and solution treatment, gives stainless steel extraordinary corrosion resistance. In the precision manufacturing of medical scalpel, it protects life safety with aseptic self-cleaning characteristics; In luxury bathroom design, its mirror luster after 20 years is still bright as new. 304, 316L, 430 and other full series of brands, for chemical, Marine, food and other 10 + industries customized exclusive protection solutions.

Nickel Strip:nanometer precision, performance pioneer
The nickel strip purified to 99.99% purity by electron beam melting technology has an ultra-low resistivity of 0.001Ω · mm²/m and a wide temperature range of -200 ℃ to 600℃. In the field of new energy power batteries, the nano surface treatment technology can reduce the internal resistance of the battery by 15%, and significantly improve the charge and discharge efficiency; In the semiconductor packaging process, the ultra-precision tolerance control of ±0.005mm ensures zero error and high stability of the chip connection.

Prepainted Steel:color empowerment, aesthetic innovation
Using the international advanced six-roll four-coating continuous production line, the fluorocarbon, polyester and other high-performance coatings are perfectly integrated with the steel plate. After 1000 hours QUV aging test, the color retention is still more than 95%; The coating that passes the T-bend test is flexible and does not crack and flake even when bent at 180°. From Nordic minimalist commercial complexes to personalized panels for trendy home appliances, 2000 + Pantone colors and customized textures make every product a masterpiece of art.
