Galvanized Steel and Galvanized Steel Coil

Galvanized Steel Coil and Galvanized Steel  are essentially carbon steel sheet coated with zinc on both sides via an electroplating method. The zinc coating acts as a barrier between the precious metal its coated on and prevents it from rusting by being sacrificed in its place. Hot dipping and electro-galvanizing are two most widely used processes used in order to produce Galvanized Steel and Galvanized Steel Coil. On most processes the hot dip process entails the passing of steel that needs to be galvanized through a bath of molten zinc. The electro galvanizing process consists of the submission of zinc by electrolytic temperament. The resultant metal has a layer of zinc tightly is a layer of zinc that’s stuck to the precious metal through a layer of iron-zinc bonding. Likewise, Galvanized Steel Coil is obtained by passing of steel coil that needs to be galvanized through a bath of molten zinc which provide great resistance to corrosion. Galvanized Steel Coil have great deforming and forming properties making them ideal for fabrication via bending and pressing.

A coating made of zinc is one of the most economical and most durable coatings out there. It’s also one of the greatest methods of preserving precious metals to date from the corrosion effect of the environment. The zinc coating will sacrifice  itself to save the underlying precious metal. The sacrificing of the zinc protective barrier begins when two different kinds of metals come in contact with the water, oxygen and carbon in the atmosphere. Zinc corrodes quite favorably for iron in steel. Zinc coating minimizes the spreading of corrosion once it’s cut from its edges or drilled holes in or metal breaks. It must be kept in mind without a zinc coasting most of the metal structures in the  world would corrode at an unbelievable rate and fall down without a moment’s notice.

There’s is no other coating that matches zinc unique combination with steel and gives as many advantages.  Thanks to zinc coating Galvanized Steel provide the longest term of protection  at lowest long term and initial cost. Since It’s easy to reproduce and economically beneficial zinc coating for producing Galvanized Steel  is used globally. An essential advantage of the process is that a standard intermediate coating thickness is applied every time. It makes the metals harder,  more stronger providing outstanding toughness and resistance. Galvanized steel coatings can literally inspect themselves. This is due to because the reaction between steel and molten zinc in the galvanizing bath doesn’t occur until the surface of the steel is completely clean of any impurities. Therefore a galvanized coating if appears safe and ready is definitely safe and ready for use.

The Difference between Galvanized Steel and Galvalume Steel

With the sustained and stable development of China’s national economy, the galvanized steel and galvalume steel has been in rapid growth, and in the field of international trading, China steel prices also attract large amount of requirements of them.

The main difference between galvanized steel and galvalume is the plate coating. Surface of galvanized steel evenly distributed the layer of zinc materials, which plays the role of anodic protection for base material, that means corrosion of zinc material give the protection of the base material , and only when all the zinc coating is corroded ,can harm done to the base metal inside. Galvalume coating surface is made from 55% aluminum, 43.5% zinc and a little amount of other elements. Galvalume coating is of a honeycomb structure under microscopic circumstance .The “honeycomb”, which is made of aluminum, contains all the zinc .In this case, the galvalume coating also plays the role of anodic protection, but with the decrease of the zinc amount, and the zinc material covered by aluminum, the anodic protection reduced greatly. So once the galvalume steel sheets are cut, the cutting edge without protection will soon be corroded. So should galvalume sheets be cut less, and zinc-rich paint or anti-rust paint applied to the cutting edge could be able to increase the life of the steel sheets.

galvalume steel

The surface of galvalume sheet is more beautiful than galvanized sheet, while the galvalume sheet is much more expensive than galvanized sheet, and the price of small spangle is more expensive than large spangle.

galvanized steel

In a rainy and humid city, once corrosion occurs at some point on galvalume sheet, it will spread increasingly on whole board if you do not take measures timely to slowly rust; while galvanized rust not spread if it occurs at a point.

Even a galvalume with greatest quality cannot overcome this shortcoming. Therefore, when we propose customers of the galvanized products, we will explain to customers the difference between them, if they require galvalume products, then we can only try to use corrosion paint immediately once it is cut.

 

Metal Roofing

Metal roofing is durable, lightweight, efficient, fire resistant and environmentally friendly. Although metal roofing is more expensive than its more common cousin-asphalt-it far outlasts it. It has been known to last as long as 50 years.

The energy efficiency of metal roofs is impressive. As much as 70% of the sun can be reflected, thus drastically reducing cooling costs. It will also help maintain the temperature inside at a comfortable level and keep the cost of heating down.

Metal roofing is an environmentally friendly option for today’s builder and homeowner. The steel used for metal roofing products is made of as much as 50% recycled materials. It is also completely recyclable itself. Some contractors will install metal roofing materials over existing asphalt shingles, thus reducing waste in a landfill.

Metal roofing material can be made of copper, galvanized steel, coated steel, stainless steel or aluminum. There are several options for panel construction – standing seam, decorative stampings and many others. Color choices are endless and can please even the pickiest client.

Most homes in hurricane-prone areas benefit greatly from metal roofing choices. Experience proves that high winds often leave these roofs intact. They are also resistant to heavy rain, damaging hail and snow and ice which can result in lower insurance rates for homeowners. Metal roofing may well be the choice of future roofs!

How Many Do You Know about Galvanized Steel and Galvalume Steel?

The best way for anti-rust of steel is hot dip galvanizing and galvalume. Galvanized steel and Galvalume steel is becoming more and more popular in modern building market to fulfill our daily life. Among so many China steel suppliers, Steel from China performs outstanding for the qualified products and good service it services.

Galvanized steel is steel that has gone through a chemical process to keep it from corroding. The steel gets coated in layers of zinc oxide because this protective metal does not get rusty as easily. The coating also gives the steel a more durable, hard to scratch finish that many people find attractive. For countless outdoor, marine, or industrial applications, galvanized steel is an essential fabrication component. Galvanized steel can be found almost everywhere. Many individuals live in steel frame houses, and buildings are often made with galvanized steel roofs. There are multiple steel parts in cars that help protect them from the weather, and it’s used in many marine applications due to its ability to withstand the salt and the elements. Besides being inexpensive, durable and effective, this metal is also popular because it can be recycled and reused multiple times.

Galvalume sheet steel is a 55% Al-Zn coated sheet steel product that is ideally suited for most types of roofing and siding applications as well as unexposed automotive parts, appliances and miscellaneous applications like furniture, outdoor cabinetry, computer cases, gutters, pipe, etc. Since 1972, over 100 million tons of licensed products have been produced globally.

No other protective coating for steel provides the long life, durability and predictable performance of hot dip galvanizing.

As asset management and life-cycle costing become even more essential, after fabrication galvanizing provides the facility to design for a predictable, engineered result.

Galvanizing is a once only process, committed to the concept of the maintenance-free use of steel, ensuring long service life and virtually eliminating disruptive maintenance.

This long-term protection is well documented world-wide in terms ahead of any other protective coating, and galvanizing continues to find new applications in almost every field of engineering.

Hot dip galvanizing protects steel from corrosion by providing a thick, tough, metallurgically bonded zinc envelope, which completely covers the steel surface and seals it from the corrosive action of its environment.

The galvanized coating provides outstanding abrasion resistance. Where there is damage or minor discontinuity in the sealing coat of zinc, protection of the steel is maintained by the cathodic action of the surrounding galvanized coating.

Metallic zinc is strongly resistant to the corrosive action of normal environments and hot dip galvanized coatings therefore provide long-term protection for steel.

The galvanizing process produces a durable, abrasion-resistant coating of metallic zinc and zinc-iron alloy layers bonded metallurgically to the steel base and completely covering the work piece. No other coating for steel matches galvanizing’s unique combination of properties and advantages:

1. For most classes of steelwork, galvanizing provides the lowest longterm cost. In many cases galvanizing also provides lowest initial cost.

2. The galvanized coating becomes part of the steel surface it protects.

3. The unique metallurgical structure of the galvanized coating provides outstanding toughness and resistance to mechanical damage in transport, erection and service.

4. The galvanized coating is subject to corrosion at a predictably slow rate, between one-seventeenth and one eightieth that of steel, depending on the environment to which it is exposed.

5. Galvanizing’s cathodic protection for steel ensures that small areas of the base steel exposed through severe impacts or abrasion, are protected from corrosion by the surrounding galvanized coating.

6. An inherent advantage of the process is that a standard minimum coating thickness is applied.
