PPGI Roofing,a specific application form of PPGI,also known as color coated galvanized steel sheet roofing,is a roofing material with galvanized steel sheet as the substrate and a layer of anti-corrosion coating pre-coated on the surface,the coating can be a variety of colors and patterns.Combining the strength of steel with the beauty and corrosion resistance of the coating, it is widely used in construction, industry, commercial facilities and other fields.In addition,PPGI has good corrosion resistance and long service life, usually more than 25 years under normal conditions.
PPGI Sheet Description
- Substrate: hot-dip galvanized or electro-galvanized steel strip
- Coating type: polyester (PE), silicon-modified polyester (SMP), high weather-resistant polyester (HDPE), etc.
- Color:RAL color card or customized as customer sample
- Manufacturing Process: curing by baking and cooling after coating with organic coating
- Features: enhance aesthetics and corrosion resistance
- Application:construction industry,home appliances and other fields
- Anti-corrosion resistance: anti-corrosion purpose is achieved through the sacrifice of zinc layer.Not only will zinc play the role of a barrier between the environment and the steel, but it will also allow itself to decompose first to protect the steel underneath and promote its longevity.

Prepainted Galvanized Steel Structure
PPGI (Color coated steel coil) is a product made of cold-rolled steel coil and (aluminum) galvanized steel coil after surface chemical treatment, coating (roll coating) or composite organic film (PVC film, etc.), and then baking and curing. This product is produced by the manufacturer in coils on the continuous production line, so it is also called prepainted steel coil. It not only has the properties of high mechanical strength and easy forming of steel materials, but also has good corrosion resistance.
Prepainted Steel Coil Layer
- Top (Finish) Coating (PE/HDP/PVDF, etc.)
- Primer Coating
- Pre Treatment (Chromate Coating)
- Plating Layer (Zn, AL, 55%AL+Zn)
- Base Metal (Cold Rolled Steel Sheet)
- Plating Layer (Zn, AL, 55%AL+Zn, Sn, Cr, etc.)
- Pre Treatment (Chromate Coating)
- Functional Painting (Epoxy, Polyester)
Coating Types of Prepainted Steel Coil
Good coating for steel structure has good mechanical properties and excell ent anti-corrosion properties. It has good stability to climate and oil - water mixture. To have a good visual effect, beautiful and generous in the decoration.The coating types currently used for PPGI/PPGL steel coil include PE, PVDF, SMP, acrylic, PVC, etc.
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.
Galvanized Corrugated Sheet Quality Inspection
In the industry, the produced galvanized roofing sheets are strictly undergoing several testing that is assuring the suppliers in supplying quality. The testing in the industry is conducted by the experts. The tests we mainly conduct is positive material identification test, hardness test, pitting resistance test, intergranular corrosion test, flattening/flaring test, mechanical test, macro/micro test, chemical test,and third-party inspections are also performed on the demand of the clients.
Galvanized Sheet Packing & Delivery
Export Seaworthy Packing:A water proof paper + An inhibitor film + A steel sheet cover with steel edge protectors and sufficientsteel straps or customized according to the need to develop different ways.
Port:Tianjin/Qingdao,or as required
Delivery Time:15 -20 Work Days,depending on the quantity
