Colorbond patina green series#

“It has a depth of colour that you can’t achieve with a powder coat colour such as Colorbond,” she says. The name Corten refers to the two distinguishing properties of this type of steel: corrosion resistance and tensile strength.Īrchitect Nicole Walters of Bespoke Architects likes using Corten for its “ever changing” look. Also known as ‘weathering steel’ Corten is a mild steel that was created to eliminate the need for painting, and develops a rust-like appearance - also known as a patina - after exposure to the weather. CortenĬorten Steel weathering steel is a type of steel that develops a protective layer of rust when exposed to atmospheric conditions. By using these types of metals, projects are rewarded with a material that will take on its own characteristics and will evolve over time. The word “Patina” describes the oxidization layer which builds up on metal surfaces. Steel coated with an alloy of Aluminium and Zinc has been extensively proven in the field, and has a service life at least 4 times longer than that of traditional galvanised steel.Each architectural metal has a different response to aging. It has excellent forming capabilities and is available in high strength grades.

The zinc/aluminium alloy coating on Zincalume® steel imparts corrosion resistance of up to four times the life of galvanised steel. The coating on ZINCALUME® steel comprises of 55% aluminium, 43.5% zinc and 1.5% silicon. These coils are then used for further processing as a universal source material to produce RHEINZINK`s high-quality roof drainage programme, pre-fabricated parts for roofing applications and facade cladding including the necessary building profiles. The quality of this material is uniform and flawless. The raw material is melted, cast and wound onto a steel sleeve in a single continuous operation. The composition of the alloy is one of the factors determining the technological properties of the material as well as the colour of the RHEINZINK patina. Electrolytically refined zinc with a 99.995% degree of purity as defined by DIN EN 1179 serves as the basis for the alloy, which also includes small yet precise amounts of copper and titanium. RHEINZINK is a trade name for titanium zinc, manufactured to DIN EN 988. High build system with a primer of 4 - 6 microns and a top coat of 20 - 25 microns. The Zinc in the coating protects the steel at the cut edges. The Aluminium component of the coating provides a tough physical barrier between the extreme atmospheric conditions and the inner core of steel.

This patented coating protects the steel in two ways: Nominal film thickness 5µm.įrom severe coastal environments to severe industrial environments, Clean Colorbond® Ultra steel is one of the most effective building material available to combat these harsh environments.Ĭoating consists of 55% aluminium, 43.5% zinc and 1.5% silicon.ĬOLORPLUS® has been developed as a premium product to endure South Africa`s harshest climates, ensuring your building will have a considerable increase in service life, superior thermal protection, added aesthetic value, cost-effectiveness and eco-friendly credentials.ĬOLORPLUS® is produced by a unique, efficient process whereby rolled steel is continuously hot dipped into a 55% Aluminium, 43.5% Zinc and 1.5% Silicon Alloy.
