Speaking of prepainted galvanized steel coil suppliers, there are really many of them! In the steel market now, pre-coated galvanized steel coils like this are everywhere. This kind of steel, with surface treatment and color, can withstand wind and rain even more. What does it mean? It is corrosion-resistant and durable. Such steel coils are not only beautiful, but also can be used in various projects, such as buildings, roofs, walls, etc. In recent years, more and more people have used this material.
Actually, this prepainted galvanized steel is a layer of color added to the ordinary galvanized steel coil, which is what we call coating. Before doing this coating, you must first clean the surface, remove oil and dirt, and then apply chemical treatment liquid to lay a foundation for it. Then the coating is applied and baked to make it firmly adhere to the steel coil, so as to better protect the steel inside.
Prepainted galvanized steel coil is generally divided into two categories, one is PPGI (prepainted galvanized steel coil) and the other is PPGL (prepainted aluminum-zinc steel coil). Although both are coated steel coils, the substrates used are different. PPGI uses ordinary galvanized steel coils, while PPGL uses aluminum-zinc coated steel coils. The aluminum-zinc type is more durable than ordinary galvanized ones, so the price will be a little more expensive.
Now speaking of prepainted steel coil suppliers, there are many factories at home and abroad, such as China, India, South Korea, and Japan, where there are many factories producing. The quality and price of each factory are a little different, but the quality of large factories is more stable because the technology they use is more advanced. However, some small factories also have advantages. They are cheap, so many customers will choose these small factories.
When looking for steel coil suppliers, we have to pay attention to a few points:
Product quality: This goes without saying. The most feared thing about buying steel is buying unqualified products. Some small factories have very thin coatings, which will fade and rust after a while. Such steel coils should not be bought no matter how cheap they are.
Service and delivery time: Some suppliers have good services and can provide services such as processing, cutting, and slitting. Sometimes they can also adjust the specifications according to customer needs, which is very convenient.
Price: Prices vary greatly from one company to another, especially when the raw materials fluctuate greatly. So you have to shop around and ask more.
Now some big brands like Alliance Steel and other well-known manufacturers not only make prepainted steel, but also various special steels, such as high carbon steel, low carbon steel, etc. Take Alliance Steel for example. They also provide processing services such as slitting, cutting, and stretching. After buying steel coils, customers can directly process them according to the specifications they want, which is very convenient.
In the international market, if you are looking for prepainted galvanized steel suppliers, most manufacturers will comply with ASTM A653/A653M standards, that is, products that meet American standards will have a certain guarantee of quality. Especially these pre-coated steel coils, which must not only be rust-proof and corrosion-resistant, but also able to withstand high temperatures and acid-base environments, so the standards and specifications are very strict.
When choosing steel coil suppliers, you should also look at the certification of the manufacturer. For example, ISO9001 quality certification, SGS certification, etc. With these certifications, the quality is relatively more guaranteed.
When buying prepainted galvanized steel coil, choosing the right supplier is the key, especially for this kind of coated steel coil used outside, the quality is not good. When buying, look more, compare more, and pay attention to the service content provided by the manufacturer, so that you can buy the right product and use it with more confidence.
