Materials Used

COR-TEN or WEATHERNG STEEL COR-TEN® has a unique look and naturally oxidizing finish make it especially desirable for many architectural projects. Weathering steel, best-known under the trademark COR-TEN steel, is a group of steel alloys which were developed to eliminate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. Cor-ten resists the corrosive effects of rain, snow, ice, fog, and other meteorological conditions by forming a coating of dark brown oxidation over the metal, which inhibits deeper penetration and negates the need for painting and costly rust-prevention maintenance over the years. COR-TEN® is a trademarked name owned by U.S. Steel.

COR-TEN Corten never completely stops rusting. The weathering process occurs after the panel is installed.  It eventually decreases and from that point on the finish acts as a protective coating for the base metal. This protective coating essentially stops the corrosion.  Laboratory analysis of the rust film have shown that the alloying elements in the steel, particularly copper, chromium, and nickel produced insoluble compounds that clogged the pores at the rust/steel interface, thereby ending the regeneration.

STAINLESS STEEL TYPE 304L Stainless steel is one of the most widely used types of metal in the world. The steel is a very durable and low-maintenance material. It is also environmentally friendly as it is recyclable. Stainless steel is basically a type of alloy that is made with at least 10.5 percent of chromium. The chromium creates an invisible chromium oxide film over the steel that is corrosion resistant. Therefore the steel is known as stainless because it can resist rust and corrosion.

Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Stainless is available in a variety of finishes No. 4 is the most typical witch is ground to roughly 180 grit finish to give the material a grainy look often seen on hand rails counter tops and kitchen appliances. Matt finish is also available and is produced by blasting with garnet to have a flat tasteful look. We also offer a distressed stainless which is less refined and has more of a rugged look desired for more rustic applications.

STAINLESS STEEL TYPE 316L We offer type 316 which is usually regarded as the standard “marine grade stainless steel”. In many marine environments 316 does exhibit surface corrosion, but far less than 304 and is offered in situations that expose the material to harsh environments. It is a option where more protection is from the elements are desired. All mentioned finishes are available with type 316L as type 304L

SILICON BRONZE Bronze is a metal alloy produced by blending copper and tin in various amounts, depending on the application. Additional elements such as manganese , lead, and phosphorous are added to create bronze with specific properties. Bronze is found in bells, statuary, bearings, gears, valves, pipes, and other plumbing fittings, and it is a sturdy, durable metal when well cared for. Humans have been working with bronze for over 3,000 years in various parts of the world, using it for weapons, coins, tableware, and an assortment of other household purposes.

One of the more unique properties of bronze is the natural patina that forms on it, turning the bronze a dark, dull color. This patina is actively encouraged with most bronze , because it provides a protective layer, preventing oxidation below the surface of the bronze . Before being shipped, most bronze is coated with a thin layer of lacquer to protect the metal and the patina, making the metal very easy to care for.

ALUMINUM Aluminum available in a variety shapes and profiles also corrosion resistant offers a cheaper alternative to stainless steel but does not have the same visual appeal.

STEEL Available hot rolled or cold role, galvanized just about any thing is possible with this material.
