Pre-Painted Galvanized Steel Coil (PPGI)

Brief Introduction
The pre-painted galvanized steel coil takes the hot-dipped galvanized steel plate as the base plate. After the surface pretreatment (chemical degreasing and chemical conversion treatment), the hot-dipped galvanized steel plate is painted with a layer of primer and then a layer of top coating with organic coatings on the front side, as well as a layer of back coating with organic coatings on the back side. Via baking for curing, the pre-painted galvanized steel coil comes out.

In addition to the zinc coating protection layer, the organic coating on the surface also plays an important role in protecting the product. It covers on the surface of the product and prevents the formation of rust. The product has much longer service lifetime than the hot-dipped galvanized stele coil by about 1.5 times.

We have rich pre-painted galvanized steel coil reserve. The products from state-owned and private enterprises are both available with all price levels to meet the diversified demands of customers in different countries and regions. Our professional buyer is familiar with production process, controls the quality of steel products, guarantees the timeliness of delivery, and provides the technical support. In respect of the logistics, we are professional to offer the multimodal transport and door to door services.
