Hot Dipped Galvalume Steel Coil

Product Specifications

Galvalume is a coating consisting of zinc, aluminum and silicon that is used to protect a metal (primarily steel) from oxidation. It is similar to galvanizing in that it is a sacrificial metal coating which protects the base metal.

Galvalume Steel:Alloy protection, durable
The aluminum plated zinc steel plate is composed of 55% aluminum, 43.4% zinc and 1.6% silicon, forming a dense protective structure. Its corrosion resistance is 2-4 times that of ordinary galvanized steel plate, and it can still maintain good condition in harsh environments such as high humidity and strong acid and alkali. At the same time, it has excellent heat resistance and high reflectivity, which can effectively reduce building energy consumption, and is widely used in industrial plants, home appliance shells, auto parts and other fields to provide long-term reliable protection for products.

Galvanized Steel:Classic rust prevention, widely used
Galvanized steel plate through hot dip galvanizing or electric galvanizing process, the formation of a solid zinc layer on the surface of the steel, effectively isolate the air and water, to achieve efficient rust prevention. Even if the zinc layer is locally damaged, it can continue to protect the steel matrix through the principle of "sacrificial anode protection". With good processing performance and high cost performance, galvanized steel plate is widely used in building steel structure, pipeline manufacturing, furniture production and other fields, is a trusted basic material in industrial and civil scenes.

Aluminum Coil:light weight, high strength, flexible
Aluminum coil is made of high quality aluminum, the density is only one-third of steel, light weight but high strength, easy to transport and processing. The naturally formed alumina film on its surface gives excellent corrosion resistance and can adapt to a variety of complex environments. Through different processing processes, aluminum coil can achieve a variety of molding effects, from the smooth lines of building curtain walls, to the precision shell of electronic equipment, and then to the efficient protection of food packaging, to meet the creative design and functional needs of various industries.

Stainless Steel:High quality, beautiful and durable
With the scientific ratio of chromium, nickel and other alloying elements, stainless steel has strong corrosion resistance and oxidation resistance, is not easy to rust, acid and alkali resistance, and is easy to clean and maintain. Different types of stainless steel, such as 304, 316, etc., designed for different use scenarios, 304 stainless steel is often used in food processing, kitchenware and other fields, 316 stainless steel is more suitable for Marine engineering, medical equipment and other environments with high corrosion resistance requirements. In addition, the stainless steel surface can be polished, brushed and other processing, showing a stylish and beautiful texture, is the ideal choice for high-end architectural decoration, precision machinery manufacturing.

Nickel Strip:Precision performance, professional choice
Nickel strip has high electrical conductivity, good temperature resistance and corrosion resistance, and plays a key role in electronics, batteries, electroplating and other precision fields. Its high purity, good ductility, can be accurately machined into different thicknesses and specifications, to meet the production needs of various precision components. In the new energy battery industry, nickel strip as a connection piece can ensure stable current transmission, improve battery performance and safety; In the field of electroplating, uniform material characteristics can ensure the quality of the coating and achieve high precision surface treatment.

Prepainted Steel:Color aesthetics, function upgrade
Through the advanced roll coating process, the surface of the steel plate is coated with organic coating, which perfectly combines the rich color expression and excellent weather resistance. The coating has good anti-ultraviolet, anti-fading ability, long-term use is not easy to aging; At the same time, it enhances the wear resistance and scratch resistance of the steel plate, and has the dual functions of decoration and protection. From the gorgeous appearance of modern buildings to the personalized design of household appliances, color-coated steel plates give unique charm to products with a variety of colors and excellent performance.

Product Description

Large Spangles

With the naked eye can distinguish the diameter of more than 3mm spangles called Large Spangles, also known as normal spangles or natural spangles. The best size recognized internationally is 8~12mm.

Small Spangles
The spangles diameter 1~2mm called Small Spangles. When the hot galvanized sheet comes out from the zinc pot, to the zinc layer without solidification spray or zinc powder, a water droplet, a zinc powder particles will form a crystallization center, so that the number of spangles per unit area increases and becomes smaller, so the galvanized surface will form small identifiable spangles with the naked eye.
Zero Spangles
The Coil can not see the Spangles with the naked eye, known as Zero Spangles, this is accomplished by controlling the chemical composition of zinc liquefaction. Hot dip galvanizing only adds a certain amount of aluminum to the zinc liquid, without adding lead, antimony, tin, can produce zero spangle products.
