   gi sheet / galvanized steel sheet is a form of galvanization. It is the process of coating iron, steel, or aluminum with a thin zinc layer, by passing the metal through a molten bath of zinc at a temperature of around 860 °F (460 °C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that stops further corrosion in many circumstances, protecting the steel below from the elements. 

   gi sheet / galvanized steel sheet is widely used in applications where rust resistance is needed, and can be identified by the crystallization patterning on the surface (often called a “spangle”).

   gi sheet / galvanized steel sheet has gone through a chemical process to keep it from corroding. The steel gets coated in layers of zinc because rust won't attack this protective metal. For countless outdoor, marine, or industrial applications, galvanized steel is an essential fabrication component.

Corporation Introduction

 Shandong Longfa is a logistics, new building materials, galvanized steel processing, plastics machinery research and development as one group of the large-scale private enterprises.It has two production lines of PPGI/PPGL, one roduction line of GI and six lines of Sandwich Board.

About 20%of our steel output is to export. Our company operates to the stringent ISO 9001 and ISO 14001 quality standards and is committed to being a first-class coated steelmaker.
  We mainly manufacture all kinds of pre-painted galvanized steel coils (PPGI), hot dipped galvanized steel coils (GI), galvalume steel coil (GL), roofing sheet, composite boards, galvanized corrugated sheet and so on.
