GALVANIZED ANGLE LINTELSThe long life of galvanized steel angle lintels reduces the chances of costly rust jacking, a problem that occurs when lintel corrosion causes severe expansion cracking or shifting in brickwork. Hot-dip galvanized steel has been used for decades to resist corrosion in the most severe environments.

The unique chemistry of zinc galvanizing actually reacts in the presence of water to create rust-resistance at the point of any surface damage.

South Atlantic’s galvanizing process creates alloy layers on the surface that are actually harder than many base steels.

The Service Life Chart (SLC) was developed based on decades of corrosion rate data collected from galvanized steel samples exposed to the five defined environments in cities all over the world, and a corrosion prediction model based on statistical methods and neural network technology.10

CHOOSE GALVANIZED LINTELS AND PREVENT COSTLY REPAIRS FROM OXIDE JACKINGAs ferrous metals oxidize they rust, this rust converts the iron or steel surface into an oxide scale that can reportedly grow up to ten times the thickness of the original structural element. In other words, a steel lintel embedded in a masonry wall and supporting the brick above a window or door header can grow in height from .375 inches to nearly 3.75 inches... What is difficult to believe is that the rust scale grows with an incredible amount of force. The upward or outward growth of the ferrous scale can easily move entireveneer sections or if restrained, crush the masonry in contact with it. Veneer anchors (wall ties) are typically designed to keep the masonry from moving laterally. Upward movement of the veneer will often disconnect or break the veneer ties...We call this movement of the masonry by the structural elements Oxide Jacking.

Once Oxide Jacking has begun, the only way to stop it is to remove the masonry and protect or replace the iron or steel element or keep the metal totally dry. Obviously, keeping the metal totally dry is not an option in the real world!

COST TO REPLACE A RUSTED OUT LINTEL: “About a grand to $1250 per if one is doing several of them... If it’s just a single lintel, I doubt it’d be less than a couple grand.”
