Hot Dip Galvanising — Commercial Building Canopies
Description

Perry Metal Protection offer Hot Dip Galvanising of Commercial Building Canopies suitable for warehousing-style applications. Galvanising Steel is widely used in applications where corrosion resistance is needed without the additional cost of on-site painting and expensive touch-ups caused by installation.

Batch hot dip galvanising provides Corrosion protection of steel by providing a thick, metallic envelope which completely covers the steel and seals it from the corrosive action of the environment. Metallic Zinc is strongly resistant to the corrosive action of normal environments and hot dip galvanising therefore provides long term protection for steel.
