Product Description

Introduction

Hot Dip Galvanized

The process where steel is coated with protective corrosion resistant zinc is known as galvanization. The coating formed by the zinc protects the steel from corrosion and in cases where the coating gets scratched, the steel is still protected. Please note that the galvanizing does not change the mechanical properties of steel.

For industries or environments where steel needs to be protected from corrosion without using stainless steel, galvanized steel or painted steel can be used. There are three common methods of galvanization which include: hot-dip galvanizing, pre-galvanizing and electro-galvanizing. The choice in method will depend on the application of the end product as well as the environment it will be applied in.

Hot dip galvanized steel:

The hot dip galvanizing process is where an already formed part, for example plate, round, square or rectangular tube is dipped in a zinc bath. A reaction takes place between the steel and the zinc during the time the part is in the zinc bath. The thickness of the zinc coating is influenced by a number of factors, including the surface of the steel, the time the steel is dipped in the bath, the composition of the steel as well as the steel's size and thickness.

One advantage of hot dip galvanizing is that the entire part is covered including the edges, welds, etc. giving it an all-round corrosion protection. The end product can be used outdoors in all different weather conditions. It is the most popular galvanizing method and is widely used in the construction industry.

Production Process:

• Inspection Raw material in site (surface zinc coating and size)
• Open Coil and Joined welding
• Continuous ERW or HFW welding
• Cutting
• End and welding inspection (Painting ends)
• Mark Packing and Trucking

Application:

• Building and structural material
• Mechanical and general engineering purposes
• Manufacturing of Bus Body, Railway Boogies
• In Telephone department as Conduit Pipes
