The process for creating expanded metal was first developed and patented in the 1880’s in Hartlepool, UK. Despite technological advancements, the modern process for expanding metal remains similar to the original technique.

What Is Expanded Metal?

Expanded metal is plate or sheet that has been cut and stretched into a mesh. Stretching the metal results in a mesh with diamond-shaped spaces – although many other patterns can be created. Many types of metal can be expanded, including: stainless steel, hot rolled steel, cold rolled steel, aluminum and more.

The pattern of the mesh can either be staggered (providing the most open area) or in a straight pattern with all rows and columns aligned. The proportion of open area determines the amount of space for the passage of air, water and light, and will vary according to the intended application of the expanded metal.

Benefits of Expanded Metal

There are several benefits to using expanded metal:

• Cost-effective: A small quantity of metal can be stretched into a large piece.
• Efficient Process: There is very little waste when manufacturing and processing expanded metal mesh.
• Good conductor: Because expanded metal is one piece, it can be excellent conductor of electricity, magnetic flux, and heat.
• Protective reinforcement: Expanded metal meshes can be combined with glass, concrete, and other materials for added strength.
• High strength: Expanded metals support weight and withstands stress better than woven metals or jointed welds.
• Low weight: Expanded metals are lighter than traditional metal sheets.
• Allows circulation: Expanded metal allows air and light to move freely.
• Acoustic properties: Specially developed meshes can enhance acoustics and provide soundproofing.

How Is Expanded Metal Made?

Expanded metal is produced by an expanding machine, which turns solid metal sheets and coils into an expanded metal mesh. The expanding machine is fitted with a knife which determines pattern for the mesh. As the metal is fed through the expanding machine, it is cut and stretched simultaneously using a pressured slitting and stretching process. The slits created by the knife allow the metal to be stretched, which produces uniform holes. To ensure a consistent pattern, the expanding machine is programmed or operated manually as the metal is fed through. The finished expanded metal is then wound into coils or cut into sheets.

Depending on the intended application, different thicknesses of metal can be used and different mesh patterns can be chosen. L.W.D (Long Way Diamond) and S.W.D. (Short Way Diamond) are commonly used to indicate the desired length and width of the diamond shaped mesh holes.

Types of Expanded Metal

The most common types of expanded metal are:

Standard Expanded Metal

Standard expanded metal is extremely versatile and economical. It comes in a variety of gauge and opening sizes. It’s often used to provide a rigid, raised, slip-resistant surface. In standard expanded metal the strands and bonds are set at a uniform angle. This provides extra strength and rigidity whilst allowing maximum air circulation.

Flattened expanded metal

Flattened expanded metal is produced by cold rolling expanded metal to flatten it. It is chosen when a smooth surface is required. The flattening process generally elongates the length of the sheet by 5%.

Hexagonal expanded metal

Hexagonal expanded metal has hexagonal openings instead of the usual diamond ones. The hexagonal shape gives the metal extra strength while allowing the passage of air, light, heat, sound and liquid. Hexagonal openings are preferred over diamond openings when the metal is heavily expanded.

Architectural expanded metal

Architectural expanded metal features the diamond pattern with added architectural features. The result is a design which combines good aesthetics, increased security and privacy, and improved ventilation. It’s suitable for functional and decorative purposes, or a combination of the two.

Micro expanded metal

Micro expanded metal features small openings in light gauge metal. The openings can be standard, flattened, hexagonal and square. This type of expanded metal is often used in filters.

We often get asked what type of Stainless Steel Sheet can be used as a kitchen back-splash.
Stainless Steel 304 is the recommended grade. It should have a #4 brushed finish. The finish of this grade looks very similar to the type used for stainless kitchen appliances. This material can be cut to the size that you need, and can be adhered to the wall using construction adhesive.

This material comes with one-side brushed (#4 grit finish). It will have a peelable protective plastic layer that can be removed once the item has been installed. The reverse side is a plain matte finish, which can be used as the gluing surface.

You must consider the direction that you wish the brushed direction to go, before ordering your sizes. Make sure that you provide those details to one of our stores doing the cutting (or place in the comments section if ordering online). The brushed grain can either go along your length or across your width of the piece(s) that you need. A typical instruction to the store might be: “please cut with brushed grain along the 12 inch length”.

Stainless steel sheet comes in many thicknesses, from 0.125” (1/8”) thick to 0.030” (1/32”) thick. While each project may have a particular thickness in mind, the most commonly used thicknesses are 0.030” or 0.036” Thick. Please keep in mind that the thicker material will cost and weigh more.

Installing Stainless Steel Back-Splash

1. Make sure that the wall is flat. Remove all build up and repair any large dents.
2. Test the placement of the sheet. Make a supporting cleat if the backsplash is not being supported by the counter top.
3. Lay the sheet with the finished (#4) side down on a flat surface.
4. Apply construction adhesive to the back side (using caulking gun), making sure that the lines of adhesive go back and forth across the entire sheet.
5. Make sure that you evenly spread the adhesive on the sheet, using a putty knife.
6. Place the stainless steel sheet against the wall with either the bottom resting against the cleat or the countertop. Once in place press the sheet against the wall.
7. Using a soft cloth, move from side to side of the sheet, pressing firmly to remove any air bubbles that could be behind the sheet.
8. Once the glue has dried and the project is complete, remove the protective layer.

Emirates Steel in the UAE is taking part in an innovative and ambitious project whose aim is to capture, reuse and store 800,000 tonnes of carbon dioxide (CO2) from its steel plant annually.  The project is scheduled to be completed by 2016. The goal is to produce steel with lower carbon dioxide emissions to the atmosphere by capturing the CO2 produced in the iron and steel making process, injecting it into existing oil fields for enhanced oil recovery (EOR) and storing it at the same time.

The CO2 supply stream from the Emirates Steel plant, contains approximately 90% CO2, and will be transported to a compression and dehydration facility at the storage site in Mussafah. The CO2 will be compressed creating CO2 with a purity of 98%, then transported through 50km of pipeline network, and finally injected into an onshore oil field, operated by Abu Dhabi Company for Onshore Oil Operations.

This project was made possible thanks to the partnership between Masdar, the Abu Dhabi national clean energy conglomerate, and the Abu Dhabi National Oil Company (ADNOC). The joint venture was signed on 10 November 2013 and will consist of three key components:

• CO2 will be captured onsite at Emirates Steel, the UAE's largest steelmaking facility.
• The CO2 will then be compressed and transported along the 50km pipeline to oil fields operated by ADNOC.
• ADNOC will inject the CO2 into oil fields to enhance oil recovery, while storing the injected CO2 underground. 

The UAE has traditionally used hydrocarbon gases in some of the Abu Dhabi fields to enhance oil production. However, with the rise in energy demand, this Carbon Capture Usage and Storage project will allow the UAE to preserve its natural gas for domestic electricity generation.

The Emirates Steel Carbon Capture and Storage project complements other technologies to reduce carbon emissions currently being researched at a global scale:

• ULCOS (Europe)
  ULCOS is the EU-sponsored Ultra-Low CO2 Steel-making project made up of a consortium of 48 European companies and organisations from 15 European countries. ULCOS is working on projects which ultimately could reduce carbon dioxide emissions from steel production by at least 50%. The most promising breakthrough technology been researched by ULCOS is the HIsarna process which is running in a pilot operation at the Tata Steel site in IJmuiden in the Netherlands. In this process fairly pure CO2 is produced which can be used for carbon capture and storage with little further cleaning necessary. The expected reduction in CO2 intensity per tonne of crude steel produced is 20% – 25%. To be able to be effective, this process will also rely on CCS to realise the 50% reduction in CO2 intensity or more.
   
• COURSE-50 (Japan)
  This programme is strongly supported by the Japanese government as they are investing in the transportation, reuse and storage of the CO2. A number of projects have been established for a long period of time especially on storing CO2 in rock structure one or two kilometers underground. The sites have been significantly tested in recent earthquakes and no loss of CO2 has been detected by the sensors placed on the surface.
   
• POSCO (South Korea)
  In Korea, POSCO runs its own programme to look at the adaptation of CCS to the Finex smelting reduction processes. They are also completing trials on capturing CO2 from a blast furnace which uses similar technology than that being researched by the ULCOS programme.
   
• China Steel Corporation with Taiwan CCS Alliance coordination (Taiwan)
  Taiwan CCS Alliance is composed of 11 companies and organisations amongst which worldsteel member company, China Steel Corporation (CSC) is a participant. The Alliance is currently focusing their research activities on two main technologies: the oxy fuel burner technology which aims at purifying CO2 by burning without nitrogen content; and the chemical absorption pilot plant which seeks to further decrease energy consumption per unit of CO2 captured. Additionally academic cooperation projects in CSC include BOF slag carbonation and microalgae carbon fixation.
   
• BlueScope Steel and OneSteel with CSIRO coordination (Australia)
  In Australia, CSIRO is working with BlueScope and OneSteel on two significant projects aimed at cutting CO2 emissions: biomass, which uses renewable carbon derived from biomass in steel manufacturing and heat recovery from molten slags through dry granulation, which captures the waste heat released from slag cooling, thus reducing CO2 emissions. These programmes have received large support from the Australian government.

Some of these R&D projects potentially can reduce CO2 emissions by more than 50%. Research is now focused on feasibility at various levels of production, from laboratory work to pilot plant development, demonstrators and eventually commercial implementation. However, initial R&D investment of several million dollars will be required for these projects to come to completion.

Further cuts in CO2 emissions will be achieved in future decades through the increased use of the R&D technologies currently funded, but also through the increased recycling of scrap and its use in the production process. According to the Global CCS Institute, around 70%-80% of emissions can be avoided by using scrap in steel production, avoiding the need for using carbon to reduce iron ore and by only using melted scrap. However, scrap and scrap availability is dependent on the cost of recovery and usually matches the economic level of iron-ore and coal requirement.  

The International Energy Agency 2013 roadmap demonstrates that CCS is an integral part of any lowest-cost mitigation scenario. The total CO2 capture and storage rate must grow from the thousands of tonnes captured in 2013 to billions of tonnes of CO2 in 2050 in order to address the emissions reduction challenge (2DS scenario).

The steel industry is fully aware of the need for implementing technological solutions to reduce carbon emissions to the atmosphere through CCS or other forms of breakthrough technologies and will continue to concentrate its efforts on this goal for decades to come.

                                                                                Kitchen sinks get a lot of use.

Among kitchen sinks, those made with stainless steel and porcelain are durable options. Stainless steel sinks last 15 to 30 years, while porcelain has a lifespan of 25 to 30 years. No matter which material you choose, proper care and maintenance will make your sink last longer.

Stainless Steel

Get the most longevity from a stainless steel sink by installing one with a low gauge number. The lower the gauge, the thicker the steel and the longer it will last. Use only nonabrasive cleaners on stainless steel, and avoid cleansers containing chloride compounds. Never use steel wool or abrasive materials. The continuous dropping of silverware and dishes into the sink can scratch it, but a satin or brushed finish will camouflage these blemishes.

Porcelain

Porcelain sinks have a cast iron core with a baked-on porcelain finish. Because chipping and scratching of the finish shortens the sink's life, placing a stainless steel rack or soft mat in the sink's bottom can prevent chipping if a knife or dish falls into the sink. Never allow coffee grounds or other acidic materials to sit in the sink. Rinse and dry the sink after each use and clean the porcelain often, avoiding abrasive cleansers, rough sponges and steel wool. Consider having the sink refinished if the finish sustains numerous scratches and chips.
