COR-TEN Steel

Corten is a weathering steel, which is commonly used in projects where painting is not required or not preferred. When exposed to weather, Corten Steel (COR-TEN™) forms a stable rust-like appearance and due to its specific mix of steel alloys, it continues to resist corrosion due to harsh weather conditions for many years.

Corten gets the name ”weathering Steel” due to its ability to form a protective layer on its surface as a result of being exposed to atmospheric conditions. Due to its chemical composition, it is able to resist atmospheric corrosion better than other forms of mild steel.

The protective layer forms as a result of the specific concentration and distribution of the element alloys in it, and the protective surface layer develops and regenerates continuously as the steel forms rust.

 

With the rising popularity of aged and weathered looking outdoor structures, so too is the popularity of Corten Steel. Also known as ’weathered Steel’, or ’COR-TEN ™’, this very durable material can be used for many different purposes in an outdoor landscape setting. With a number of considerations to take into account that vary from other mild steel projects, Metalmac can produce top quality customised Corten Steel fabrications for any purpose.

Because of its rustic visual appeal, Corten is commonly used for some of the following examples:

Planter Boxes	Doors	Lighting	Gates
Fences	Retaining Walls	Landscape Artwork

 

Corten Steel was originally developed in 1933 and patented by the United States Steel Corporation. Not along after this, the developers realised that this steel had unique controlled corrosion properties and applied the trademark name Cor-Ten.

Due to the exceptional mechanical resistance of corten, it was used early on in railroad passenger cars both painted and un-painted, storage containers and for bulk transport purposes.

Conduit Packaging Jig

Hi All, it's been a while since my last post as I have been really busy fabricating away and seems the rebound out of COVID has been as dramatic for me as the initial slowdown during the peak of lock down....I hope many of you are also seeing the same and if you are not quite there yet hopefully not far from it although I am mindful there is still some hardship out there so all the best if in that situation. One of the more unique projects of late is developing a Conduit Packaging Jig to help a local (Hills District, Sydney) manufacturer to streamline that operation. The Business owner armed with some concept drawings engaged Metalmac to tweak the design in to a practical working fabrication. They are now able to 'stack crates with ease' and 'saving heaps of time compared to previous methods'. Some core functions of this project are the jig is actually founded on a trolley base, which means it can easily be pushed around the yard to the location it is required. Once the jig is in the correct location it becomes very easy to position and fix the timber packaging and easy to stack in the storage location.

Metal Fabrication

LOOKING FOR AN EXPERT STEEL FABRICATOR?

Customized metal fabrication is a process that involves measuring, cutting, machining and welding any kind of steel materials to specific dimensions, to meet the needs of the customer. A fabricator will usually be called upon to carry out the work because the requirements of the item can not be met through a commercially available or a standard-sized mass-produced item.  

 This makes a metal workers role extremely diverse as every new job brings a new challenge both from creativity and an engineering standpoint. 

It was the challenge and reward described above that always interested expert steel Fabricator David McNeice, and this interest carried him down the path of refining his craft to the point where he decided to start his own engineering workshop that we now know as  Metalmac. 

Based in The Hills Shire of north-western Sydney, David services everyone from local domestic and commercial clients, through to onsite maintenance work and welding for major projects and industrial manufacturing facilities. 

 At Metalmac, all our work and processes are born out of a desire to create the most enjoyable and rewarding experience for our customers as possible. This includes helpful ideas and advice on new job enquiries, highest quality guaranteed workmanship and great value for money. David works as a one-man operator, so you are not paying for the overheads that come with running staff and a large company.

WORKING WITH A METAL FABRICATOR

As previously mentioned, A metal fabricators role is extremely diverse with each project having its own context and requiring a customised engineering solution. Quite often, It is not only the experience of the fabrication company doing the work but also the ability of its employees to create, design and adapt dynamically.

 

1. Job Requirements
   When a customer first meets with a custom metal fabrication expert, they will start by asking a series of questions about the engineering requirements of the project. From here they will consider several different aspects such as dimensions, structural strength and integrity, weight specifications, load specifications, architectural considerations, cost considerations, environmental and any other specific requirements.
2. Materials
   With this information in mind, the fabricator can then decide on the most appropriate material for the role. For example, the product may be intended for use in rust-prone environments meaning high-quality stainless steel may be best suited for the role. In other cases, a cheaper material may be able to replace a more expensive material to meet cost constraints.
3. Design
   After a decision has been made on requirements and materials metal fabricator can then use his creativity and technical knowledge to create a design incorporating all of the required components. When he is satisfied with the design it can then be sent to the client for final approval.
4. Assembly
   Usually the most interesting and rewarding part of a job, the construction phase can include any number of tools and processes including machining, welding, CNC cutting, forming, bending, forging, stamping and many other manufacturing processes.A high-quality end result will be determined by a number of qualities about the individual(s) performing the work including, craftsmanship,  attention to detail, equipment used, materials used and time taken.

Welding Service

LOOKING FOR A PROFESSIONAL WELDING SERVICE?

In reality, most people could pick up a welder and crudely fuse two pieces of metal together, however, to do it precisely, structurally sound and visually appealing is an art that takes years of practice and experience.

Based in The Hills District and Servicing the greater Sydney Metropolitan area, Metalmac owner David McNeice left behind a successful professional career sitting behind a computer to pursue his passion as a Welder and Metal Fabricator. Being able to express his creative side through solving engineering problems and creating effective solutions with his technical know-how is something David finds much more rewarding than his previous employment.

MOBILE ONSITE WELDING

One of our core services at Metalmac is providing a mobile onsite welding service to the greater Sydney metropolitan area. In many cases, this is to service larger industries that have extensive onsite maintenance schedules for both heavy equipment and infrastructure but could also be on the local domestic level services structures such as gates, fences, trailers or anything else made of structural steel.

TYPES OF WELDING

MIG

Metal Inert Gas Welding or metal Active Gas Welding is one of the most commonly used techniques in industrial welding practices as it is relatively fast and efficient when compared to some of the older practices.

A MIG welding torch has a thin wire electrode that feeds from a roll on the machine itself. The speed at which the wire is feed can be controlled by the operator as well as the desired power output, amperage. Also feed from the welding gun is a shielding gas that helps prevent oxidation and makes a better quality weld. Atmospheric gases can cause porosity and fusion defects, so the use of argon, helium, carbon dioxide or a mixture of all 3 is used to mitigate this issue.

The advantages of using the MIG is it is easy to use and surface preparation is not as important when compared to other welding processes. The disadvantages are that it gives up a small amount of control when compared to the TIG.

TIG

Tungsten Inert Gas Welding, sometimes referred to as GTAW (Gas Tungsten arc welding) is commonly used on non-ferrous metals such as copper, magnesium and aluminium, but is also the preferred method of welding thin pieces of stainless steel and other iron-based metals.

The big advantage of TIG welding is greater control over the welding process, giving the operator a better chance at creating stronger and higher quality welds.

The disadvantages are the process is slower which adds more time to a job and this welding technique takes an experienced operator. Learning this method of welding is a complex art that can take a good while for the operator to become proficient in.

Stick Welding

Often considered ‘the old way’ of doing things a stick welder is the most basic of welding machines using a stick rod as the electrode, which is also the filler metal that helps to fuse the metals together. There are no protective gases used in stick welding.

Generally, stick or arc welding is still a very good option on heavier structural steels and thicker pieces of metal. When it comes to welding sheet metal or other thin pieces then this is not the best option.

A stick welder is very easy to use and very cheap to purchase.

Plasma Arc Welding (PAW)

The key differences between GTAW and PAW are the electrode is positioned in the body of the torch so the plasma arc is separated from the shielding gas. The gas plasma is then forced through a fine bore copper exit orifice on the torch at high velocities. This high-velocity gas exiting the nozzle is suitable for both welding and cutting purposes not unlike an oxy torch.

The key difference between plasma arc welding and oxy-acetylene welding is the plasma arc is around 28,000 degrees Celcius. By comparison, an oxy-acetylene flame is approximately 3150 degrees Celcius and a normal welding arc is around 10,000 degrees Celcius.

Gas Welding

This is another welding process becoming less and less used as time goes by due to the effectiveness of the TIG. This process usually refers to the use of oxygen and acetylene mixed together in the welding torch and this flame is used to create heat on the job surface. A rod is then applied to the heated joint which then melts to provide the filler metal and the joint strength.
