Pre painted steel is a bare metal substrate or corrosion-resistant substrate that has had paint applied to one or both sides through a continuous coil coating process, which produces a uniform paint finish. The steel is uncoiled, cleaned, and chemically treated during the process. Depending on product specifications, one or both sides may then be primed and coated, oven cured, and recoiled.
TIANJIN MUCHANG supplies a variety of prepainted steel sheets and coil products to meet our customer's needs. Our value-added service capabilities include slitting, shearing, stretcher leveling, blanking and cut-to-length, and metallurgical support.

Pre galvanized steel coil is a steel product made by uniformly coating a layer of zinc on the surface of cold-rolled or hot-rolled steel strip through hot-dip galvanizing or electroplating process, and then winding it into a coil shape. It is mainly composed of base steel and surface zinc layer. The base steel provides mechanical properties such as strength and toughness, while the surface zinc layer plays a protective and decorative role.
Pre-galvanized steel coils are a kind of coiled product with a pre-applied zinc coating on the surface of steel. They are processed through hot-dip galvanizing or electro-galvanizing techniques, which form a uniform and dense zinc layer on the surface of the steel. This zinc layer can effectively prevent the steel from rusting and corrosion, enhancing its durability. At the same time, it endows the steel coils with good corrosion resistance, processability, and decorative properties. Pre-galvanized steel coils are characterized by a smooth surface and uniform color. They are widely used in numerous fields such as construction, automotive, home appliances, and hardware products, and can be used to manufacture products like roofs, vehicle bodies, home appliance casings, and hardware fittings.

Market Status Quo and Development Trends
With the continuous development of industries such as construction, automotive, and home appliances, the market demand for pre-galvanized steel coils has maintained a steady growth. In the future, pre-galvanized steel coils will develop towards the directions of higher corrosion resistance, better surface quality, lower costs, and greater environmental friendliness. At the same time, with the continuous progress of technology, their applications in emerging fields will also continue to expand.
Features of Pre painted Galvanized Steel Coil
Strong corrosion resistance:
The zinc layer can effectively prevent air and water from coming into contact with the steel, and can prevent the steel from rusting and corroding for a long time even in harsh environments.
Good processing performance:
It has excellent flexibility, ductility, and weldability. It can be smoothly processed through operations such as bending, stamping, and stretching, and the zinc layer is not easily damaged.
Excellent surface quality:
The surface is highly flat and has a uniform color, which can provide a good foundation for subsequent surface treatments and has a good appearance effect.
Good economic performance:
Although the procurement cost is slightly higher, due to its long service life and low maintenance cost, the comprehensive cost throughout the entire life cycle is low. Moreover, it has high production efficiency and can save resources.
Good environmental performance:
No harmful substances are released during use. After being discarded, the steel and zinc can be recycled and reused, which meets environmental protection requirements.
