Galvanized Steel Manufacturer
Galvanized steel manufacturer designs and manufactures a large range of galvanized structural items. These include pipes, air-conditioning equipment, fencing, and hardware. Its durability means that it can last for years and requires less maintenance than stainless steel.
The process of dipping metal in molten zinc has been around for over 200 years. It protects steel from corrosion and extends its life.
Cleanliness
The cleanliness of hot-dip galvanized steel products is a critical factor in their durability, formability, toughness, tensile strength, weldability galvanized steel manufacturer and resistance to cracking and fatigue. The cleanliness of a galvanized product can be evaluated by using a variety of methods. Some cleaners may be harmful to the zinc surface, so they should always be tested in an inconspicuous area before use over large areas.
General contaminants such as dirt, mud and oily spots can be removed with ordinary laundry soaps. For stubborn stains, pressure washing at a low pressure (less than 1450 psi) with water is advisable. Oxalic acid cleaners, such as those used to clean metal car parts and truck bodies, often provide satisfactory results for removing mild rust stains from the galvanized surface. Graffiti removers containing non-alkaline solvents are also effective in removing paint build-up and stains from galvanized surfaces. They should be rinsed thoroughly after application. In addition, it is important to avoid exposing galvanized steel to environments with pH below 6 or above 12 for long periods of time. If this happens, the galvanized coating is susceptible to rapid corrosion.
Strength
Galvanizing is a centuries-old process that protects steel from corrosion. The process involves dipping standard steel in molten zinc, creating a layer that bonds with the metal surface. This coating protects the steel from environmental elements, including moisture and temperature variations. In addition, it prevents rust by acting as a buffer between the iron and oxygen. While it’s impossible to completely prevent rust, galvanized steel is much more durable than uncoated steel.
Several methods can be used to galvanize steel, including hot-dip and electrogalvanizing. The former uses a bath of molten zinc to coat the steel, while the latter utilizes an electrical current and a zinc anode. Both processes can be customized to meet customer needs.
The durability of galvanized steel makes it an excellent choice for many industrial applications. In the construction industry, it’s a popular choice for rebar, tubing, rails and poles. It’s also used in bridges, sculptures and other structures that are typically found outdoors. Galvanizing these structural pieces reduces maintenance costs and increases longevity. It also provides a more aesthetically pleasing appearance than other types of treated steel.
Durability
Galvanized steel materials can withstand harsh environmental conditions and last for a longer lifespan than ungalvanized counterparts. They are a popular choice for plumbing and construction projects, as well as outdoor equipment like fencing and guardrails. The zinc coating on these metals protects them from rust and corrosion, making them durable and reliable.
Compared to aluminum, galvanized steel is more resilient and has greater resistance to corrosion and stress-induced cracks. Its durability also makes it an ideal material for roofing projects. It can withstand heavy rain and snowfall without affecting the integrity of the structure or its components.
When using galvanized steel in high-pressure applications, a metallurgical bond between the zinc layer and the structural steel is critical to ensure maximum durability. Typically, the galvanized steel manufacturing process involves immersing the steel in molten zinc to form a protective coating. The resulting product can be customized in various shapes, sizes, steel grades and standards, surface finishes, color preferences, and other factors. The coating can be sprayed, brushed, or rolled onto the steel to achieve the desired appearance.
Weldability
Galvanized steel offers a wide range of benefits for manufacturers that use it to fabricate automotive parts, including its ability to provide enhanced rust and corrosion resistance. It is also an excellent choice for building pylons that support high-voltage power distribution to factories and hospitals. The process of galvanizing was first developed in 1836 by French engineer Stanislaus Tranquille-Modeste Sorel, who invented the process by cleaning the steel and then dipping it into molten zinc to create a protective coating that is long-lasting.
However, these positive attributes can make galvanized steel difficult to weld. Its thinness makes it prone to burn-through, and its zinc oxide coating can produce defects if welded incorrectly. These problems can result in costly manufacturing delays and lost production time.
Fortunately, these issues can be easily addressed with the right welding equipment and proper preparation. A good starting point is to pair your current Pulsed MIG welding process with a metal-cored wire that is designed specifically for welding galvanized steel. This will help improve the speed and quality of your welds.
Cost
Galvanized steel is a durable, affordable material that offers high corrosion resistance and long life. It has been used in a variety of industries for years, including aerospace and construction. It is especially suited to products that are exposed to moisture or other environmental conditions.
The process of galvanizing was first introduced by a French chemist in 1742 and soon became popular. It involves cleansing and heat-treating rolled coils of steel before dipping them into molten zinc. The coating prevents rust, increases the durability of the metal and helps to protect it against harsh environments.
In addition to its durability, galvanized steel is also more cost-effective than other coated materials. It has a lower initial cost, requires less maintenance and saves time and alloy steel plate money on inspections. It is also self-healing, meaning that it corrodes preferentially in areas where the coating is damaged, protecting the steel underneath.
To help steel importers, buyers and structural engineers make an informed decision about the type of galvanization that is best for their project, the LCCC provides a free online calculator that compares the initial and lifetime costs of galvanizing to paint systems. Users can input the specific parameters of their project in three quick screens to receive a customized comparison.
