What Is PPGI Steel?

PPGI steel is short for pre-painted galvanized iron, which refers to pre-painted zinc-coated steel. As the name implies, PPGI commonly uses a hot-dip zinc-coated steel (GI) as a substrate. Then the GI sheet in coil form is cleaned, pre-treated, and painted with layers of organic coatings, such as PE, SMP, HDP, PVDF, etc. The painting process is continuous, which is known as coil coating process. That’s why PPGI steel consists of several layers, namely base metal, zinc coating, pre-treatment (chemical conversion coating), primer coating, and top/back coating. Below is a structure drawing for you.

PPGI Sheets & Coils

According to the shape, we divide prepainted galvanized steel into coil and sheet. The thickness of our PPGI is from 0.12 mm to 1.2 mm. To make it easy to transport, PPGI sheets are often rolled up into coils. While for specific purposes, PPGI coils can be sheared and profiled into plain or corrugated steel sheets. Commonly, PPGI coil is a kind of base material, which is suitable for investment; while PPGL sheet is a kind of finished product, which can be used directly. But essentially, pre-painted galvanized steel sheets and coils are the same things. Just choose the right form according to your needs.

PPGI Steel Price in 2021

PPGI steel price is from $500 to $1400 per ton. In the first three months of 2021, the steel price in China kept increasing. It is estimated that it may steadily rise in the future. There are several reasons.

1. The cost of raw materials rises.

2. Environmental cost. Influenced by environmental policy, some small and medium-scale steel mills may close. It means the production capacity will be less.

3. The operating cost of the steel industry increased greatly, including labor costs, financing costs, etc.

4. Market demand is recovering. Influenced by COVID-19, some projects were delayed last year. But in 2021, most of them started again. When demand is exceeding supply, the price will go up.
