In 2013 I completed this sliding gate design. Layering the carbon steel with stainless steel, this gives the work a nice 3d appearance. The surrounding steel work is the traditional wrought iron theme with a touch of stainless to bring it into the modern era.Plastic spacers are used to reduce the chance of electrolysis across the dissimilar metals. All stainless steel and fasteners used are grade 316 stainless steel.
For those with some welding skills this gate feature is available to purchase in polished kit form so please contact me via my web page or FB page if you would like to purchase.
Motivation I have a few outdoor designs which I am working on, I am writing this blog with the aim to better understand weathering steel and it’s advantages and limitations.
Intro So weathering steel is often known by one of it’s brand name’s “Corten”. This material can be cut, bent, drilled etc and then left in it’s raw state (No painting or surface treatment) then used for it’s intended purpose.
Availability – Australia So far I have found a supplier that stocks 3mm sheet form only. At time of this blog a 3m x 1.2m sheet is $330, as opposed to a mild steel sheet which is $135.
How it works Basically the weathering steel is similar to stock mild steel but classed as an alloy steel due to its additional properties of Chromium, Copper & Nickel. These elements assist in forming an oxide layer on the material surface which in effect allows the material to continually rust to a limited depth which increases the materials resistance to atmospheric corrosion.
Comparison This material was developed as a cheaper substitute for “Stainless steel” which is one of the best materials to use in corrosive environments.
Applications Weathering steel is often chosen A; Because of its corrosion resistant properties and B; Because of its aesthetic appearance. It is popular for use in outdoor sculptures, marine environments, Bridge piling & Exterior facades on buildings to project a rustic theme.
Disadvantages Using weathering steel in construction presents several challenges. Weathering steel is not rustproof in itself. If water is allowed to accumulate in pockets, those areas will experience higher corrosion rates, so provision for drainage must be made. Weathering steel is sensitive to humid subtropical climates. In such environments, it is possible that the protective patina may not stabilize but instead continue to corrode; in this case Stainless steel would be the preferred option.
Weathering of the material can result in discoloration of the surrounding environment, IE; city sidewalks, as well as other nearby buildings. Staining can be prevented if the structure can be designed so that water does not drain from the steel onto concrete where stains would be visible.
Welding I- Contact your local welding supplier to find out what welding electrodes should be used. Challenges that exist are ensuring that weld-points weather at the same rate as the Weathering steel.
My first creation was this bar stool height table, which I labelled Table “X”. I marked out this table pattern by hand; the whole table was made by hand. All of my later work was designed on computer drawing software which gives the cleaner sharper look.
I found out that I had this artistic streak when I began teaching fabrication and welding apprentices in 2004. I was delivering the topic of “Geometric Construction” which is the cornerstone for metal fabricators to use when marking out patterns and shapes on metal.
I realised that by combining straight lines, parallel lines, arcs, tangents & radius tangents and bringing all these techniques together you can pretty much create any shape and pattern that you desire.
I was excited and enjoying my new career as a lecturer within the fabrication & Welding trade and at the same time was equally excited to discover that I had an eye for detail when it comes to creating a new approach to Metal Art & Design which I labelled “Freestyle Metal Art (FMA)”.
Ok, here goes, my first blog. I am choosing the topic of “Metal Art” Because that is my passion and what I love to do. I am sure I will start with producing ramblings but hopefully my blogs will evolve into topics of interest for others and with any luck people will have a desire to comment and contribute to what I write.
I am unsure how the whole blog thing works and I have watched plenty of youtube clips and read articles but still am none the wiser. I am just biting the bullet and venturing into the unknown.
Attached is a photo from my web page www.freestylemetalart.com This photo is one of my many designs, but does suite my traditional style of Metal Art.
