What is PPGL Roofing Sheet?
PPGL Roofing Sheet is a covering material for the roof of a house, consisting of zinc-aluminum sheet steel (55% aluminum, approx. 1.6% silicon) and functional paint, which can withstand the roof loads directly and provide wind, rain, and thermal insulation. Popular Metal roofing sheets include PPGL PPGI GL GI roof sheets with corrugated/trapezoidal/ribbed surfaces, etc.
All Types of PPGL Steel Sheets
Prepainted galvalume steel sheets and coils can be processed through bending, cutting, stamping, etc. to produce roofing sheets with different surface shapes, Wanzhi Group provides raw materials (PPGL coils and sheets) and various shapes of PPGL panels.
- PPGL corrugated sheet: PPGL steel sheet with a corrugated surface, the strength and loading capacity of the sheet varies with the change of wave valley, wave pitch, and wave peak. Commonly used in industrial plants and tops of greenhouses.
- PPGL trapezoidal sheet: PPGL steel sheet with trapezoidal cross-section, with good wind and drainage resistance, commonly used in building surfaces with high drainage and wind pressure resistance requirements.
- PPGL flat plate: Prepainted steel sheet with a smooth and flat surface, weaker in structural strength than profiled sheet, commonly used for roofs of residential buildings, villas, and other buildings with high demands on appearance.
- Other profiled plates: ribbed sheets, hidden sheets, hyperbolic sheets, and curved sheets, have the advantages of waterproof and good structural strength and are often used in the roofing of high-grade buildings, stadiums, and other buildings.
Process of PPGL Roofing Sheet
Prepainted galvalume steel roofing is made of cold rolled steel firstly treated with galvanized aluminum alloy and then color coated, according to the process, it can be divided into color-coated hot-dip zinc-aluminum coated steel and prepainted electro-galvalume steel.
- Hot-dip: The zinc-aluminum alloy layer is thicker, and the anti-corrosion time is longer, suitable for the outdoor environment.
- Electroplating: The zinc-aluminum alloy layer is thinner, and the corrosion protection time is not as long as the hot-dip coating process, suitable for indoor environments.
PPGL Roof Coating
PPGL Roof sheet Coating is available in PE, SMP, PVDF, HDP, and paint film: top 10–40 microns, back 5–20 microns.
- PE PPGL steel Roof: known for its low cost, good corrosion resistance, and workability, it is a popular color coating material.
- SMP PPGL steel Roof: Good hardness, abrasion, and heat resistance.
- HDP PPGL steel Roof: Excellent corrosion and UV resistance.
- PVDF PPGL steel Roof: Excellent weathering, corrosion and stain resistance, and longest color retention.
What are the Functions and Uses of PPGL Roofing Sheet?
PPGL Roofing Sheet has corrosion resistance, high-temperature resistance, high heat reflectivity, fire resistance, lightweight, high strength, etc. Due to the ease of processing, transportation, and installation, prepainted steel has gradually become a popular roof covering material for residential, commercial, industrial, and agricultural buildings.
Functions and Benefits
- Drainage: The surface of PPGL sheet panel is designed to effectively drain rainwater.
- Wind Pressure Resistance: The corrugated design enhances the structural strength of the PPGL sheet to resist varying degrees of wind pressure.
- Thermal insulation: Aluminum alloy has high heat reflectivity, and prepainted galvalume has a good thermal insulation effect.
- Fire protection: The metal sheets are fire-resistant.
- Load-bearing: PPGL steel helps to reduce the load of the building, and at the same time, PPGL roof sheets have good structural strength.
PPGL Roofing Sheet Used for
- Industrial plant
- Farms, greenhouses
- Gymnasium, temporary building
- Warehouses, office buildings, shopping malls
- Residence, villa
How Much Does the PPGL Roofing Sheet Cost?

PPGL Panel Sheet Maintenance Methods
Although PPGL Roofing Sheet has excellent weathering, UV resistance, aesthetics, and durability, it is important to protect the coating from damage during use and storage to prolong the service life of the PPGL steel sheet and to keep the color and appearance stable for a long time.
Storage
- Keep the storage environment dry and ventilated.
- Keep away from corrosive substances such as acid, alkali, and salt.
- Avoid direct sunlight.
- When water or moisture accumulates on the surface of PPGL steel, it should be treated in time.
Maintenance
- Do not damage the surface coating of steel during processing and transportation.
- Regularly clean the impurities accumulated on the surface of the roofing sheet.
- Regularly check the surface of the steel, if there are scratches, rust should be repaired in time.
PPGL Roofing Sheet has excellent corrosion resistance and high-temperature resistance in high humidity and high salt spray environments and is a high-quality roof covering material for buildings and industrial plants in coastal areas.
