UNDERSTANDING THE QUALITIES AND STRENGTHS OF GALVANIZED BOLTS.
Most bolts that are being sold to the market right now are made from steel materials. While steel bolts are durable and can last for a long time, one problem that they always encounter is corrosion. Corrosion has always been the determining factor of the longevity of bolts, especially if they will be used in environments that can trigger and hasten their rusting process.
Bolts and the Galvanising Process
Fortunately, one process that can help in protecting bolts from corrosion is the hot-dip galvanising process. Bolts that are composed of iron tend to corrode whenever they interact with oxygen in the atmosphere and water. But with the hot-dip galvanising process, bolts are subjected to several chemical baths that will effectively clean their surface before plunging them into a bath of zinc ammonium chloride and bath of molten zinc. The last two baths are essential in removing any lingering oxides and providing a protective layer against external elements of corrosion.
Once the bolts are dipped into the molten zinc bath, they are spun in a bucket to eliminate any excess zinc and subsequently cooled. The bolts will then be inspected and assessed to see if they have passed certain specifications set by the appropriate standards of the manufacturer.
Advantages of Galvanised Bolts
Galvanised bolts boast several benefits that enable them to be useful in different situations and applications. Some of these advantages are:
Excellent Durability: The galvanising process has equipped bolts with a surface layer that is strong and durable. The strong bond between the zinc coating and the base steel of the bolts enables them to maintain their surface coating for a very long time. The intermetallic layers of the said coating can readily help in resisting abrasion, heavy impact, scratches, and extreme temperatures. And even if this coating gets damaged, it will sacrifice itself first before allowing any damages to the base steel.
Uniform Coating: What is great about the galvanising process is that it coats the whole base steel of the bolts. The molten zinc from one of the process’s steps fluidly flows over and into all areas of the fastener, reacts with the base steel of the fastener, and produces a consistent coating thickness all over the material. Every corner and edges of the bolts are coated, leaving no exposed areas for corrosion and other damaging elements.
Increased Longevity: The durability of the coating, as well as its complete coverage over the fastener, allows the fastener to last for a very long time and to be used in a lot of applications. The service life of bolts hugely relies on the thickness of the coating and the presence of various elements like temperature, humidity, and pollutants. If the fastener has a thick zinc coating, then its life will be longer since damaging and corrosion elements must penetrate all the surface coating before they could reach and damage the base steel of the fastener.
The galvanising process enables bolts to withstand corrosion effectively, making them great for applications that are frequently exposed to oxygen, water, and other damaging elements. Additionally, this process prolongs their lives, which can be cost-effective in the long run. If you want to have your own hot-dipped galvanised bolts, feel free to contact us at Ebolts Online Store.
