Product Description
Galvanized Steel Sheet & Plates, are intended for use where greater corrosion protection is required without painting. A lower cost alternative to stainless steel, galvanized sheet and plates have a rust free protection for up to 30 years, while maintaining strength with a durable surface coating. Metals Depot stocks many sizes in precut sizes, full mill sizes or we can hot dip virtually any size and quantity required for your welding or construction project.
Galvanized sheet / plate can be cut, machined or welded by common methods used for regular steel, but adequate ventilation should be used to avoid inhalation of fumes when heated. Sheared edges are not galvanized and can be treated with a cold galvanizing paint to maintain protection if desired. All dimensions are before the galvanizing process.

Main Application
Galvanized steel is available in a variety of forms, such as galvanized pipes and galvanized wire.
Galvanized metal has found its way into several household appliances such as washing machines, air conditioning housings, hairdryers, etc.
It is also used to make wrought iron gates and other items,high tension electrical towers, protective gears, highway signs,make metal pails,build houses,etc.
Main Features
1.Light weight; the density of aluminum is 2.73g/m3, only 1/3 of that of steel.
2.High strength; high strength can be achieved through composition configuration, processing and heat treatment methods.
3.Corrosion resistance; it has the ability to self-rust, and the oxide layer formed can prevent metal oxidation and corrosion, and it has good acid and alkali resistance.
4.The surface treatment is diverse and beautiful.It can be anodized, electrophoresis, chemical treatment, polished, and painted.
5.Good plasticity and easy to process；
6.Good electrical conductivity.Non-magnetization and low EDM sensitivity can prevent electromagnetic interference and reduce flammability in special environments.
7.Easy to install; aluminum can be connected by riveting, welding, gluing, etc.
8.Environmentally friendly, 100% recyclable.
