Topspan steel is one of the options which can help you to save your money.  Ithana tospan steel products were produced by the high tensile steel which is able to carry the heavy weight. It is light weight with Galanize, the corrosion protection, so it is unnecessary to be colored. This product is designed to be able to be superimposed that make a transportation, levying and installing easier. For these reasons make this produce popular for general constructions than normal topspans which you can find from the market. For the noncorrosive roof, we know that "Topspan" have to carry a lot of heavy weight from all roof tile, so it needs to be the noncorrosive topspans. Nowadays, Ithana tospan is the best choice of the noncorrosive topspans which is produced from Corrosion Protection Technology with Corrosion Protection covering processes or Hot Dip Galvanized as used for producing cars. It is not only Ithana topspan noncorrosive, but also the processes of installing that use galvanized nails to make it completely noncorrosive.

Notable qualifications of Galvanized steel

Corrosion resistance
Galvanize is working as the protection barrier for a reaction of steel's surface and air. In addition, Galvanize has a effective qualification to protect the steel from the sacrificial corrosion by using itself to be corroded. However, it can resist a corrosion in corrodible area.

Forming
Ithana Galvanized steel is produced by continual hot dip Galvanized which make the steel have a durable surface for a cracking or a peeling during board or press forming.

Welding
Ithana Galvanized steel could be welded by several methods such as the electric resistance welding, brass soldering, Single Spot welding, Seams welding and Stud welding.
