Galvanized steel coils are widely used in the construction industry, as raw material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommended for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 100 – 180 grams per square meter.
Hot-dip galvanized steel coils are produced by immersing steel in a zinc bath. An appropriate galvanizing process requires a pretreatment process during which the steel passes through different baths which prepare the surface for zinc coating. In this stage, chemicals are used to clean the surface of the steel. After the chemical treatment, the steel coils pass through a bath of melted zinc at temperatures around 460 ° C. The resulting uniform coating is finished through a process of skin-passing to provide smooth and shiny appearance of the finished product. To store for a longer period, the hot-dip galvanized coils can be delivered with a final oil coating, according to the customer’s demand.
PROFILAND STEEL produces hot-dip galvanized steel coils with very good work at further cold forming and bending processes.

Technical specification:
• Steel grade: DX51D+Z
• Zinc coverage: 40-275 g/sqm on both sides (depending on the requested specification);
• Thickness: between 0.2 mm and 4.00 mm;• Width: 600mm,914mm,1000mm, 1220mm, 1250,1500mm;
• Coil weight: 3-10 mt;• Coil ID: 508 mm;
• Coil OD: 900-1500 mm ;
Depending on their usage, the hot-dip galvanized coil can be delivered slightly oiled.

Characteristics:
a) Low-cost: Zinc coating is cheaper than other coatings.
b) Lasting and durable: The zinc coating is attached by chemical reaction to become the surface of the steel sheet, therefore, the coating lasts for a long time. Generally, standard zinc coating(Z60 to Z80) can last for 50 years without any repair,
while in coastal areas lasting 20 years.
c) Strong toughness: The zinc coating owns special metallurgical structure which bears mechanical damages in delivery and application.
d) Overall protection: The steel materials are totally submerged into the alloy and galvanized in every place; even the depressions,concaves, and sharp corners of the steel materials could be galvanized and protected.
e) Convenient:Galvanizing is easier and more convenient than other coating application. Besides, applied in construction, there’s no need to paint once the galvanized steel coils&sheets are installed in construction sites

Production Application:
Galvanized steel coil products are mainly used in construction, light industry, auto industry, agriculture, animal, husbandry and fishery, and commercial.
a.) Construction industry is mainly used in the manufacture of corrosion resistance of industrial and civil construction roof panel, roof grille, etc;
b.) Light industry with its manufacturing home appliance shell, civil chimney, kitchen utensils, etc;

In this episode of TIG Time we are welding on an engine mount that was brought to us for some repair. The mount is made of 4130 Chrome Moly and goes on a small, 2 seat aircraft called a Hummel Bird.

Aircraft engine mounts often develop small cracks that need repaired due to engine vibration. In this case, we show you how to prepare for welding tubular mounts by drilling a pressure hole as well as how to weld the crack. After the crack is welded, we will let the part cool down and re-weld the hole.
