Difference Between PPGI And PPGL Steel Sheets
1. Coating material:
The surface of the PPGI is sprayed with a color coating. This coating gives PPGI steel plate good rust resistance and beautiful appearance, common colors are red, blue, white, gray and so on.
The surface of PPGL is coated with hot dip galvanized aluminum-zinc alloy. This special alloy coating makes the steel plate excellent in corrosion resistance and weather resistance.
2. Performance Characteristics:
PPGI has excellent weather resistance and corrosion resistance due to its coating properties. So it is ideal for use on the exterior walls and roofs of high-end buildings.
PPGL steel sheets stands out for its excellent corrosion resistance and high temperature stability. It enables it to maintain its performance stability in harsh environments such as seaside and industrial areas. And it is often used in home appliance housings, automotive housings and other fields.
3. Usage and Application Scenarios:
PPGI because of its beautiful, rust and other characteristics, building wall panels, roofs, warehouses, shopping malls and other fields are inseparable from it.
Due to its excellent corrosion resistance and weather resistance, PPGL is more used in the manufacture of home appliance housings, automotive housings and other products requiring high corrosion resistance.
4. Price and cost:
Generally speaking, PPGI as a high-end product of color steel coil, its price may be relatively high.
In contrast, PPGL’s price is likely to be more affordable, making it more competitive in applications such as walls and roofs for mid-range buildings.
Operation Precautions of PPGL Steel Sheets
1. Handling and storage
When handling, avoid directly dragging or hitting the edge of the steel plate to prevent damage to the coating or deformation.
Store steel plates in a dry, well-ventilated place. This can avoid direct sunlight and wet environment, prevent the coating from fading or rust.
2. Preparation for processing
Before operation, ensure that the working area is clean, so as not to contaminate the surface of the steel plate.
The use of appropriate fixtures and supports ensures that the steel plate remains stable during processing.
3. Cutting and processing
Use sharp knives for cutting to reduce burrs and unevenness of the cutting surface.
During bending, stamping and other processing, workers should adjust the machine parameters according to the thickness of the steel plate and the coating characteristics to avoid the coating peeling or cracking of the steel plate.
4. Welding and connection
If PPGL steel plates need to be welded, appropriate welding methods and parameters should be selected to reduce the impact of welding on the coating.
For the connection part, self-tapping screws, rivets, etc., can be used. But care should be taken not to over-tighten, so as not to destroy the coating.
Maintenance Advice
- Coating protection: Regularly check the coating condition of the surface of the steel plate. If the coating is found to be damaged, peeling and other phenomena, it should be repaired or re-coated in time. The integrity of the coating is important for protecting the steel plate from corrosion and aging.
- Waterproof treatment: For the steel plate used in a humid environment, it should be regularly waterproof treatment to improve its waterproof performance. You can use special waterproof paint or waterproofing agent. This ensures that the surface of the steel plate forms an effective waterproof layer.
- Anti-rust treatment: If the steel plate rusts, you can treat it with a special rust remover and then reapply the anti-rust coating. At the same time, it is also necessary to pay attention to regular inspection of connecting parts and fasteners. This ensures that it is securely fastened and prevents corrosion problems caused by loosening.
