Product Description
Hot-dip galvanizing reacts molten metal with an iron matrix to produce an alloy layer, thereby combining the matrix and the coating. Hot-dip galvanizing is to pickle the steel parts first. In order to remove the iron oxide on the surface of the steel parts, after pickling, they are cleaned in an aqueous solution of ammonium chloride or zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride. , and then sent into the hot dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life.
Hot-dip galvanizing is one of the effective means to delay the environmental corrosion of steel materials. It immerses the cleaned and activated steel products in molten zinc liquid. Through the reaction and diffusion between iron and zinc, the surface of the steel products is Zinc alloy coating with good adhesion. Compared with other metal protection methods, the hot-dip galvanizing process combines the physical barrier and electrochemical protection of the coating, the bonding strength between the coating and the substrate, the density, durability, maintenance-freeness and economy of the coating. It has advantages in terms of durability and adaptability to the shape and size of products. At present, hot-dip galvanized products mainly include steel plates, steel strips, steel wires, steel pipes, etc., among which hot-dip galvanized steel plates account for a large proportion.
The production process of hot dip galvanizing is as follows:
Base material → oil removal → water washing → pickling → water washing → rinsing → flux solution → drying → hot dip galvanizing → cooling → inspection → packaging
Application scope
For a long time, the hot-dip galvanizing process has been favored by people because of its low plating cost, excellent protective properties and beautiful appearance. It is widely used in automobiles, construction, home appliances, chemicals, machinery, petroleum, metallurgy, and light industry. , transportation, electric power, aviation and ocean engineering and other fields.

EN8/EN9 En Series Round Steel BarThe chemical composition of EN8 includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements. The carbon content is the most important, usually between 0.36-0.44%. EN8 has good weldability, and it can be welded by conventional welding methods, such as arc welding, gas welding, etc. However, when performing high-intensity welding, care needs to be taken to control the welding heat to prevent material deterioration. EN8 carbon steel bars are widely used in the manufacturing industry, especially where high strength and wear resistance are required. They are often used to manufacture bearings, pins, mechanical parts, etc..
PPGI Steel CoilPPGI is GI steel sheets coated with a colored paint layer.
Characteristics: PPGI steel sheets offer not only the corrosion resistance of galvanized steel but also a vibrant and customizable appearance. They are widely used in construction, manufacturing, and decorative applications.
Uses: Roofing, wall panels, door frames, appliance housings, etc.
The full form of PPGI is pre-painted galvanized iron. It is a kind of color coated steel or pre-painted steel, which is an extension of GI. As the name implies, it uses zinc-coated steel as substrate, and then it is cleaned, pre-treated, and applied with layers of coatings to make it more beautiful and durable to use. We adopt the coil coating process to make PPGI coils. With slitting, shearing, and roller equipment, we also have strips, plain and corrugated sheets for sale.- PPGL Steel CoilPPGL is GL steel sheets coated with a colored paint layer.
Characteristics: PPGL provides enhanced corrosion resistance along with a wide range of color choices. It is suitable for architectural and industrial applications in harsh weather conditions.
Uses: Frequently used in the production of roofing, wall cladding, oil tanks, refrigeration equipment, and more.
PPGL stands for pre-painted galvalume steel, which is a kind of color-coated steel with GL as substrate. It combines the strength of steel with excellent anti-corrosion of Zn-Al coating. The galvalume coating is made of 55% aluminum, 43.4% zinc, and 1.6% silicon. Except for their excellent corrosion resistance, PPGL sheets also have high thermal reflectivity, which makes them heat-resisting. - Prepainted Galvalume Steel PPGL CoilColor coated coil can be divided into ordinary PE, high corrosion resistant HDP, high corrosion resistant silicon modified polyester SMP, high corrosion resistant fluorocarbon PVDF, super corrosion resistant nano fluorocarbon PVDF, aluminum magnesium manganese color coated board, printing color coated board, etc. Used for roof panels, wall panels, furniture, household appliances, auto parts, etc, it maintains the strength of galvanized steel, while its organic coating provides a variety of colors and attractive appearance.
- Color Coated Aluminium CoilColor-coated aluminum coils are the surface coating and coloring treatment of aluminum plates or aluminum coils. The commonly coated aluminum coils are fluorocarbon color-coated aluminum coils and polyester color-coated aluminum coils. They are widely used for Veneer, aluminum honeycomb panels, aluminum ceilings, roof surfaces, leftover material, cans, and electronic products. The performance of the color-coated aluminium coil is very stable, and not easy to corrode. Besides, the surface layer of the color-coated aluminum coil can achieve 50 years of quality assurance after special treatment. The weight of them per unit volume is the lightest among metal materials. Color-coated aluminum coils are currently the most popular new material.

Wood Grain Color Coated Roll Coil DescriptionWood grain color coated roll coil is made of refractory materials, such as steel and aluminum, which makes it an excellent choice for areas prone to wildfires or areas where fire safety is a concern. Unlike solid wood, wood grain board is not easy to rot, deform and crack. It also has strong resistance to impact and weather damage, which makes it ideal for harsh environments. Compared to solid wood, wood-like metals require minimal maintenance. It can be easily cleaned with a hose or high-pressure washer, and will not fade or discolor over time. Wood grain color coated roll coil products are widely used in construction, such as wall panels, siding, garage doors, fences, etc., and are also very popular in decoration and furniture.- Pattern Printing / Pattern Color Coating CoilThe patterned color coating coil is a galvanized steel coil or a AL-ZN steel coil as a base material. This is why the surface has incredible resistance to corrosion and rust. In addition, its thermal insulation effect is also great. Because the color coated steel coil is light in weight, it is convenient to transport and install, which greatly shortens the construction period. It weighs thirty times as much as a brick wall. The printed color coated steel coil is available in a variety of colors and patterns to meet exact needs. Lastly, it has a smooth surface, which means that no additional decoration is required.
- Color Coated Galvalume Steel Coil PPGLPPGL steel is a durable, colorful and economical building material. It is the abbreviation of color coated aluminum-zinc plated steel coil, which is based on aluminum-zinc plated steel coil. The aluminum-zinc coated steel is then continuously painted in coil form. Due to its heat resistance and corrosion resistance, it has become a material for various construction purposes, especially roofs and walls. Because it contains 55% aluminum, the corrosion resistance of PPGL coil is much better than that of PPGI, which can greatly extend the service life.
- G90 Galvanized CoilThe coating designation G90 represents the type of coating and the weight of the applied coating. The letter "G" indicates that the coating is galvanized, meaning zinc-based. Meanwhile, the number "90" represents the thickness of zinc on the surface of the steel coil. Galvanized steel coil is covered with a zinc coating to provide corrosion resistance. The G90 protective coating prevents moisture from reaching the steel structure, thereby improving the corrosion resistance of the steel. This can extend the life expectancy of the steel. G90 is the large coat weight and therefore provides strong protection.
