    What Is Sheet Metal Fabrication?

    You can find sheet metal in just about anything and just about anywhere. It

    may be found in home appliances, aircrafts, construction, HVAC, furniture,

    cars, and in various industries. There are probably hundreds of productsthat contain this pliable and durable material. The raw material is used for a

    wide variety of applications because it can be bent, stretched, shaped, and

    cut into practically any shape. And the manufacturing process to which a

    piece of sheet metal is shaped into the required part through material

    deformation or removal is called sheet metal fabrication.

    The process for fabricating sheet

    metal may be categorised into

    two: forming and cutting. Forming

    may be done through different

    means such as stretch drawing, roll

    forming, spinning, or bending.

    Meanwhile, cutting can be applied

    with or without shearing force.

    When manufacturers cut without

    shearing force, they can utilise

    water jet cutting, plasma cutting, or even laser beam cutting. The process

    used will depend on specifications for fabrication.

    Note that the thickness of a sheet metal is called the gauge. The number

    will vary from 3 to 38; a higher gauge will mean a thinner piece of metal.

    The thin piece of sheet metal may be referred to as a foil while a thicker

    piece of metal may be called a plate. The required gauge will, of course,

    depend entirely on the application needed for the sheet metal. The same

    consideration also goes for the type of metal needed as sheet metal can

    come in stainless steel, steel, aluminium, copper, brass, titanium, zinc, and

    others.

    Another element to the fabrication process of sheet metal is welding. After

    parts have been shaped according to specifications, they have to be

    assembled and tack welded. There are different welding techniques the

    manufacturer can use in order to prevent warping of or visual defects on

    the raw material. The most common techniques are TIG, MIG, andOxyacetylene. TIG (Tungsten Inert Gas) is generally used for difficult welds

    such as for s-curves and round shapes on copper and titanium. Meanwhile,

    MIG (Metal Inert Gas) is ideal for joining wide-ranging metals and gauges

    and Oxyacetylene can straighten warped steel.

    Once welded, the manufacturer finishes off the fabrication job usually by

    sandblasting, priming, and then painting. The finishing touches, as always,

    are done according to the project specifications.

    So the next time you see any kind of consumer product, look at a car, or

    stare out at an airplanes wing from your airline seat, know that a lot of

    work has gone into just a few of its essential metal parts. And should you

    have need for metal fabrication, always go to an experienced and expert

    manufacturer to ensure that each piece has been cut, shaped, welded, and

    finished to the highest quality.Click herefor more.

    What Are The Main Features To Specify When

    Getting Acoustic Louvres Made?

    Certain buildings, factories,or big plant rooms, can

    create sound pressure levels

    that go beyond the existing

    or required noise criteria

    prescribed in specific

    locations. To address the

    reduction of noise egress, an

    acoustic louvre will have to

    be mounted behind a louvrepanel. But aside from enabling noise reduction, an acoustic louvre can also

    assist with ventilation, which means that construction of this important

    feature will require great consideration. This will guarantee that the

    intended purpose is met and that establishments that use it can expect

    longevity.

    The first thing to consider before getting acoustic louvres made is where

    they will be used. Applications for the acoustic louvre are generally for

    refrigeration machinery, underground or enclosed car parks, processingplants, plant rooms, cooling towers, and the like. Because it will come in

    two standard ranges and it can be made in different metals, it is critical that

    the application be determined at the design stage. Doing so will guarantee

    the best noise control and economical solution. It should be pointed out

    that retrofitting is not only quite pricey but may also disrupt operations.

    The two standard ranges for acoustic louvre panels are the R type and the

    LP type. The choice will depend on the required acoustic performance; the

    R type delivers maximum noise acoustic performance, with normalpressure drop while the LP type gives the normal acoustic performance,

    with minimum pressure drop. Some manufacturers may also add

    perforated underside for maximum sound absorption.

    While construction of these noise-reducing panels will be determined by its

    application, it is recommended that businesses specify acoustic louvre

    panels to be weather-rated and vermin proof. A non-combustible acoustic

    fill should also be requested for added safety.

    As for the materials used, most businesses might have their acoustic louvre

    panels made from galvanised mild steel. But it can also be made from other

    metals such as aluminium and stainless steel.

    Another main feature to specify in the construction of acoustic louvre

    panels is the blade styles. It would be ideal to complement the scale and

    aesthetics of the building or structure where it will be mounted. In addition,

    some consideration should also be placed on blade orientation as this, too,

    can have bearing on the overall look of the building as well as have anaffect on acoustic performance.

    Finally, businesses should also specify bird or insect screens for their

    acoustic louvre panels as additional forms of protection.Know more about

    Discover The Benefits Of Acoustic Enclosures In

    Industrial Environments

    Noise is inevitable in industrial environments. Most machines can producenoise that exceed limits, which can lead to serious health risks for those

    who need to work around them. Employers are bound to protect their

    employees from noise levels above 85dB(A). Naturally, having workers

    merely wear protective earmuffs or ear plugs cannot stifle certain levels of

    noise. A more effective solution needs to be implemented. And that

    solution may be delivered by an acoustic enclosure.

    An acoustic enclosure can be used and designed for fixed or mobile

    applications. Enclosures for diesel and gas generators are effective buffersfrom the machines noise. An acoustic enclosure may also be customised as

    a soundproof control or observation room, which will allow employees to

    work in a quiet environment and protect them against the noise in the

    plant. But generally, acoustic enclosures serve to muffle or shield the noise

    emanating from certain engines and machineries such as compressors,

    pumps, grinders, and the like.

    Aside from protecting employees against the health risks of a noisy

    environment and helping the business adhere to noise regulation, anacoustic enclosure may also guarantee the uninterrupted and optimal

    performance of engines or machines. Manufacturers of this type of

    industrial enclosure

    can design it

    according to its

    application and add

    features that would

    prevent, for

    instance, electricmotor heat. The

    addition of a small

    ventilation fan may

    address this need.

    Meanwhile, external materials and finishes may be specified according to

    the weather conditions the acoustic enclosure will encounter.

    Since an acoustic enclosure can be designed and installed outdoors (not

    just indoors), nearby areas may also benefit from its noise-reducingcapabilities. Instead of leaving a booming generator on top of a building or

    by the side of a structure, its owner may well protect neighbouring

    buildings from its noise by housing it in an acoustic enclosure. The

    enclosure may even be finished with paint that will match the overall

    appearance of the building so that it does not ruin its exterior area. This

    consideration of aesthetics is especially important for establishments that

    may be situated in a business or tourist area.

    Generator sets, compressors, pumps, blowers, and every other noiseproducing machinery and engine are not only unpleasant to hear. High

    levels of noise can also create health risks, particularly when workers are

    exposed to it constantly. By using an expertly constructed acoustic

    enclosure, employers provide a quiet and healthy working environment for

    employees so that production is efficient and uninterrupted. Visit this

    Minimise Downtime At The Job Site With Vandal

    Covers

    Towering skyscrapers. Highways and streets stretching for miles and miles.The food on your table and the gadgets you can't live without. All these

    modern marvels would not have been made possible without the

    construction and mining industries which rely heavily on earth moving

    equipment like graders, bulldozers, excavators, backhoes and scrapers.

    While ancient builders constructed timeless wonders using ingenuity and

    sheer manpower, today's builders cannot create modern wonders as

    quickly and as efficiently without these equipment.

    Heavy equipment manufactured by the likes of Daewoo, Caterpillar,Mitsubishi, Yanmar, Komatsu, Kubota, Case, JCB and Bobcat are built tough

    and can handle the demands of both construction and mining sites.

    However, there is one particular part that can leave them vulnerable to

    vandal attacks as well as harsh work environments the operator's cab.

    In order to protect heavy

    equipment against vandal

    attacks, construction and

    mining firms can implement avariety of strategies. These can

    include beefing up security

    especially during night time

    when operations have ceased,

    the use of security equipment

    like alarms, padlocks and

    CCTV. But if there is one

    convenient and cost-efficient

    way to protect a construction or mining firm's investment, that would bevandal covers or vandal guards.

    Vandal guards may be made of aluminium, punched, welded or woven

    mesh, solid steel, solid plastic or flat bars and are installed onto the earth

    moving equipment's cab through buttons, brackets, hinges and padlockable

    over-centre catches. While vandal guards can prevent stones hurled against

    it by saboteurs or during industrial demolitions or mining operations, meshvandal guards can allow visual control for the operator without

    compromising his safety. In addition to this, they are designed to allow the

    quick and safe entry and exit of the operators.

    When it comes to turning projects in time or meeting quotas, time is of the

    essence. Construction and mining firms must ensure continuous operations

    and minimise or prevent the cessation of operations due to various causes

    including the breakdown of earth moving equipment. Breakdown of

    equipment can translate to delays, which in turn can mean loss of profitsand opportunities, or even hassles with the client. As such, it is essential to

    put in place measures that will ensure continuity of operations. In addition

    to these, vandal covers are a small investment that a firm can make in

    order to protect some of its most important assets its heavy equipment.

    Shipping Container Modification For Industrial

    Purposes

    Various industries have utilised

    shipping containers to transport

    finished products and raw materials

    over long distances over land and sea.

    Because of their great size as well as

    their sturdy built and ability to

    protect goods against the elements,

    they are seen as a cost-effective

    means for transportation. However,after use, many of these containers

    are left when their cargoes have been

    delivered because it is more cost-

    effective for businesses to purchase new ones rather than ship these

    containers back to their countries of origin.

    As such, used shipping containers have created new industries which take

    advantage of their sturdiness. Some enterprising individuals make use of

    shipping containers for a variety of purposes including homes, mobile barsand storage units. Even businesses engaged in various industries have

    benefitted greatly from shipping container modification. One of the most

    obvious and perhaps most important advantage of appropriating shipping

    containers for other purposes is that it allows consumers and businesses to

    recycle a material into something beneficial instead of letting them languish

    in shipyards, accumulating rust when they can be given another lease on

    life through creativity.

    In addition to being sturdy, shipping containers are versatile and can bemodified to meet the various needs of businesses. Many industries have

    modified shipping containers into acoustic enclosures for their generators,

    compressors, pumps and similar equipment which can create a lot of noise.

    They can also be modified for storage, even those which require special

    storage features like temperature control. Shipping containers can also be

    modified as a mobile acoustic enclosure using attenuators, acoustic doors,

    absorptive linings and fuel tanks to enable sound absorption.

    Shipping containers can also be modified into access doors for plant

    equipment that may need seals or specific door frames. They can also beutilised as a weather-proof enclosure for machineries that need to be

    placed outside.

    Converting shipping containers for these and other industrial applications

    requires specialist expertise in order to design and modify the shipping

    container that meets a business's needs. In order to do this, the

    modification specialists need to visit the job site or area where the

    modified shipping container will be used and placed in order to fully assess

    the environment as well as come up with the necessary modifications tosuit these. Modifications can either be made in a factory or on site when

    the scale of the project is too big and too inconvenient to transport. For
