Galvanized vs Galvalume®

What is Galvanized Steel?


Carbon steel is inherently susceptible to corrosion, which means it must be protected by some other metallic coating that is less corrosive. Carbon steel sheet is called “galvanized” when coated with a thin layer of pure zinc.

This coating provides two types of corrosion protection for the steel: “barrier protection” (sealing the surface from air and water) and “sacrificial protection” or “galvanic” protection—especially at scratches and cut edges.

This is an electrolytic process whereby the base metal is protected, but at the expense of the coating. The zinc “sacrifices” itself to protect the underlying layer of steel.

What is Swarf? [Video]

Posted by Kimberly Reichert on Jun 20, 2019 9:31:11 AM

Swarf are the shavings of metal debris produced during machining. These chips or filings can also be produced during woodworking, grinding and other manufacturing processes. Metal, wood, plastic and stone can all produce this debris which is often called “swarf”.

At S-5 Manufacturing, the small chips and shavings created during the cutting, milling or drilling of stainless steel, aluminum and brass parts could be called “swarf”, but we commonly call them “saw chips” or “turnings” and produce tons of them each month. In that case, they are automatically collected at their source by special equipment and recycled regularly. We recycle approximately 40 Cu. Yd. or 14,450 lb. of aluminum chips every month. That amounts to over 7 tons per month of “swarf”. There are additional shavings produced when machining our brass and stainless steel clamps and brackets, but that volume is much lower than the aluminum.

What is COR-TEN® (aka Corten, CorTen)?

Posted by Kimberly Reichert on May 23, 2019 11:32:46 AM

COR-TEN® is a special steel alloy that has a weathered, rusty-orange look. The material, also referred to as corten or CorTen, was developed to eliminate the need for painting the metal. Cor-Ten forms a stable rust-like appearance after being exposed several years to weather.

U.S. Steel owns the trademark on Cor-Ten. This steel alloy is encouraged to rust – and form a dark brown oxidation. This rust forms a protective coating over the surface that slows further corrosion.
