What is Fabricated Sheet Metal Used For in HVAC?

Fabricated sheet metal is commonly used in the ductwork of HVAC systems. Traditional ductwork is installed in commercial and industrial buildings for the heating and cooling systems. Sometimes, however, the regular metal ductwork must be routed in odd ways, due to various obstacles in the path. Longer piping would be added to get the metal fittings and tubes installed to go around all those barriers.

Due to the odd routing of all the ductwork, the HVAC system would ultimately have to run harder to heat or cool the building properly, because it has to run the heat through a long set of pipes. For an HVAC unit to run efficiently, fabricated sheet metal would be utilized to run around the obstacles for a more direct path from the heating/cooling system to the air vents.

Fabricated sheet metal enables one to bend, and turn the metal to the desired shape, so it will fit much like a jigsaw puzzle in the areas you want them to. This would eliminate the need for all those extra pipes and fittings that only succeed in using more energy to run the HVAC system. Also, by using more customizable ductwork, like the sheet metal, you’re prolonging the life of your unit, because it’s not working harder to heat or cool your space.

How Does Fabricated Sheet Metal Have Advantage Over Regular HVAC Ductwork?

We’ve already discussed the fact that sheet metal is more customizable when it comes to installing the ductwork for a building. They work perfectly for fitting into what seems like an impossible spot for regular pipes. The places that fabricated sheet metal fittings work best are:

  • Around Sharp corners
  • Behind pipes
  • In tight, cramped spaces

When using only traditional HVAC ducts, one would have to install an intricate system of pipes to avoid the places where you can’t fit regular ductwork. Now, it’s much easier when you can get someone to fabricate ducts using sheet metal. The pipings and fitting would be cut and shaped precisely to your specifications.

Installing the fabricated pieces of ductwork helps the HVAC unit run in the most efficient way possible for any commercial or industrial building. Finding a shop that can fabricate sheet metal accurately isn’t always easy. If you’re looking to get some ductwork customized for your building or space, give us a call at 408-295-2182. Our skilled professionals can fabricate your ductwork for whatever specifications you need, and we can also install them if you want.

The Advantages of Fabricating New Sheet Metal for Your HVAC System

Another few years have passed and now it’s time for you to perform maintenance on your HVAC system. It takes time and money, and then you have to do it all again in the next few years. You should instead consider replacing the material in your HVAC system with sheet metal. Though thin, sheet metal has proven to be strong, efficient, and cost-effective. Whether you are a facilitation manager for a large company or responsible for new construction projects, sheet metal is highly recommended for ventilation ducts.

Sheet metal can withstand large amounts of pressure along with the harsh weathers ranging from frigid to scorching. It is lighter than other material used for ventilation ducts. Regardless, it’s the custom fabrication of the sheet metal that is specifically tailored for your business. Sheet metal is cost- and time-effective because it’s simpler to make. The material isn’t imported from across the sea. Not only does it save money for HVAC contractors, but it saves on your company’s energy bills in the long run.

The Efficiency of Sheet Metal for Your HVAC System

There are a number of ways that sheet metal is economical for your company:

  • custom fabrication reduces air leaks
  • the relatively smaller size allows for better air volume and distribution
  • easier to manage

Sheet metal is always custom fabricated, and this is beneficial. Regular, generic-shaped air ducts are not as stable; they have a tendency to move and bend while in use. This causes air leaks. Air leaks mean that your ventilation would have to work even harder to get the air to its destination. It will stay on longer and increase your energy bill. Custom fabricated sheet metal is sealed tightly and cut to fit your building. It will not experience energy losses like normal air ducts.

Due to its smaller size and sealed design, sheet metal ducts allows air to flow through in smaller volumes. Therefore, the fresh air will make it to the designated rooms faster. These ducts simply have better control of the air volume. As a result, this is another way your HVAC systems won’t have to work as hard and saves your company money on the energy bill.

Maintenence should still be required every few years for your HVAC systems. However, sheet metal makes it easier for HVAC technicians to service. You also will not be required to have to replace it every few years. This is because custom fabricated sheet metal ducts are more durable, and is yet another money-saver.

If you’re ready to save money on your energy bill, then call us today at 408-295-2182 and inquire about sheet metal ducts for your building.

How Quickly Can Ductwork Fabrication Be Done

When adding a new unit or expanding the additional system, ductwork replacement may be necessary. The process requires careful planning and coordination, so this alone could affect how long a system takes to build. Ductwork fabrication can completed in a matter of days depending on several factors.

Factors affecting the amount of time it takes to complete a system

Design of system-The design of the system is a factor. A more complex design may require more planning and labor. Intricate planning may be required if there are efficiency requirements that must be made. Repairs are almost unavoidable whenever a system is being upgraded. There may be multiple temperature controls that have to be incorporated into the design, which affects complexity of the overall system. If additional supply ductworks are needed than originally required, then the size of the system is affected.

Size of the project-The size of the project may vary. For example, there may be multiple stories to account for in the planning, which could affect the amount of labor that could be required. The square footage of each room affects the length of the project.

Improvement or replacement-If the system upgrade involves simply replacing the existing unit with a similar one, then there will be little changes to the design in most cases. This means that ductwork may need moderate improvements to resolve leaks or vulnerable areas.

Quality of existing ductwork-If the ductwork is aging and failing in multiple areas, then the ductwork has to be replaced. If there are energy efficiency concerns, then the ductwork should be replaced.

Permitting-Agencies may affect the timeline. The permit application may take longer to process if working with a particular agency. The duct installation project timeline could be affected if there are any delays in processing the application.

Accessibility of the ductwork-If the ductwork isn’t accessible, then the project will take longer to complete. The ductwork can be replaced quickly if it is very accessible.

How long does it take to install a ductwork?

The ductwork project takes between 1 to 4 days. The ductwork is mostly impacted by the size of the project. If there are no unexpected challenges, then the system will take only a few days to install. In some cases, the installation can be completed in one day.

New ductwork may be required if a new HVAC system is being installed. Multiple variables affecting the timeline of the project such as the design of the system and the size of the project can also affect the overall cost of the system. Most installation projects can be completed in a matter of days.

Why You Should Replace AC Ducts

When you are outside, you can breathe fresh air from all directions. In a building, you might receive the majority of your air from your air conditioning (AC) ducts. Learn why you should replace AC ducts.

Most air is a combination of many different elements, including oxygen. The dirtiest air is filled with germs, dust, smoke and other airborne contaminants. Some diseases are spread through the air.

When your workers have the freshest air with the highest percentages of oxygen, they are the most productive. They can concentrate and complete tasks faster. Here are some of the reasons for replacing AC duct work:

  • Fresh Air
  • Reduce Airborne Contaminants
  • Prevent Diseases
  • Indoor Air Quality

Do you know what is breeding in your air duct work?

Replace Air Ducts

When an athlete goes to the sideline, he gets oxygen to reinvigorate him. Fresh air can increase your workers’ productivity. They can process information faster and complete their tasks on time.

Do you want your workers to be coughing into their keyboards? This prevents them from completing their assignments. It also spreads germs and increases the chances that others will get sick too.

More sick time will lead to fewer productive hours. Airborne diseases can cause simple fatigue or lead to more serious lung problems. This is especially true during the flu season.

There are many other types of contaminants that simply make breathing more difficult. Dust can clog up the lungs. Coal mine workers eventually get “black lung” due to long periods of exposure to airborne contaminants. How do the lungs of your employees look?

As a building owner, you are not only responsible for your employees, but also guests and vendors. What do they say about your Indoor Air Quality behind your back? Do they rue visiting your establishment or leave with a hacking cough?

If you care about promoting an image of excellence, does this not extend to having superior Indoor Air Quality also? Rats, squirrels, bats and birds nest inside your air ducts. Vermin leave all sort of waste material that are then recycled into the air, you breathe.

Replacing your AC ducts can help all people breathe easier, avoid airborne diseases and work more productively. Are you convinced that your AC ducts need cleaning? If so, call us today at 408-295-2182

Will New Ductwork Improve Efficiency in an HVAC Unit Of a Facility?

Heating and cooling are a big part of your energy bill, and HVAC ducts are a major source of energy loss through leaks and lack of insulation. As much as 20 percent of your energy loss can be recovered by improving the efficiency of your HVAC unit. Look at your monthly energy bill, and extrapolate 20 percent of that over the next 10 years. Can you afford not to have new ductwork?

If you’re fortunate, your HVAC ductwork may last up to 10 to 15 years before it starts to deteriorate. If your ductwork has never been replaced in the past 10 years, you shouldn’t be surprised if your energy bills start to rise unexpectedly. You may even experience problems in less than 10 years, depending on how reliable your previous installer was.

Poor HVAC ductwork not only reveals itself in your power bill, but also in poor air quality. If your facility’s air has begun to smell stale, the health of people who live and work there may be affected. By restoring your HVAC unit to its original air circulation parameters, you’ll improve health and morale. By delivering more oxygen, new ductwork can improve efficiency by improving your efficiency and the efficiency of those you share your environment with.

Ways to Determine if You Need New Ductwork

Here are simple tests you can make to see if your ductwork is beginning to deteriorate:

  • Physically trace the ductwork through crawl spaces, looking for holes, tears, or disconnected joints.
  • Feel if the air flow and temperature remains constant throughout the rooms; a variation means you’ve got a leak.
  • Contact a mechanical contractor who specializes in HVAC and have your ductwork tested with a duct blower.

These tests will identify leaks, but what about energy losses through poor insulation? If your HVAC ductwork has developed leaks, then it’s likely the insulation is beginning to degrade as well. Again, a mechanical contractor specializing in HVAC can help you determine if that is the case.

What Exactly is Custom Sheet Metal Used For?

Custom sheet metal fabrication involves cutting and bending a metal sheet that is typically less than ¼ inch thick. Custom sheet metal fabrication is needed when standard parts do not fit, or when the job has specific manufacturing challenges. The ability to do this helps solve problems that cannot be solved using off-the-shelf parts. The range of applications is nearly limitless.

Custom sheet metal fabrication has its use in restaurants, hospitals, nursing homes, architectural applications, and supermarkets. It also has a place in production design such as for specialized hoppers and holding tanks. One of the most common uses is in specialized HVAC systems that must bend around existing structures or other building systems.

Why Choose Custom Components?

In some applications, the only choice is custom sheet metal fabrication because the exact component needed is not available or does not exist at all. Even when a standardized component or fitting does exist, there are reasons why custom sheet metal is preferable.

· More choices. With custom sheet metal fabrication you can choose different materials than those from which standardized parts are made. This means that you can use a heavier or lighter material, as the needs of your project dictate. It is possible to create a component that works better than the original and has better performance.

· Better quality. Custom fabrication provides better quality because the piece is expertly manufactured on an individual basis. It is not stamped or cut using a mass production process. This means that care is taken in each step of the process to make certain that it is within engineering tolerances.

· Exact fit. Sometimes standardized parts may not fit precisely. This can create problems such as leaks, movement, or component wear. When an exact fit is needed, custom sheet metal fabrication can provide better long-term results than a mass manufactured part.

There are many reasons why you may need custom sheet metal fabrication services. Whether you need a custom component, or want to upgrade or change an existing one, it is important to find a firm with experience in all types of projects. If it is new construction, or a retrofit, experience is the key to success. You also need a firm that has the latest in design and fabrication technology.

What is Sheet Metal Fabrication?

Manufacturing any product out of metal requires sheet metal fabrication. It is the fundamental process of taking a plain sheet of metal and forming it into the shape required for a part or component part of a larger manufactured good. Companies in the computer, electronics, medical equipment, and appliance industries are common sheet metal fabrication users. They require metal fabricated parts for a wide variety of projects. Some fabricated metal components are large, such as those needed for a household appliance, while other are tiny, such as those often needed by the computer and electronics industry.

There are three methods of sheet metal fabrication: cutting, forming, and finishing. Anything constructed of or containing metal must go through one of these processes. Here is a detailed description of each:

Cutting

Cutting is just what it sounds like, the process of cutting sheet metal into smaller pieces. However, one cut does not fit all. The size and application of the fabricated part indicates which cutting process is employed. Shearing uses a cutting machine to cut large pieces of metal into smaller ones. Electrical Discharge Machining (EDM) uses an electrode spark to melt conductive materials. Abrasive cutting uses a saw to cut through the metal. Precision parts require laser cutting.

Forming

Once the metal has been cut using one of the above processes, it must be formed.

Depending on the specifications, one or more forming processes are employed. Metal can be shaped through the rolling process, which uses a roll stand to roll over the metal. Bending and forming are the methods of shaping metal by hand. If the metal requires a design, we employ the metal stamping process. When necessary, metal pieces are joined through welding.

Finishing

No metal product is ready to ship until is has gone through finishing. During this process, all rough spots and edges are made smooth. The parts are cleaned and rinsed so they are ready as soon as they are shipped.

Sheet metal fabrication requires a provider with the equipment and experience to create metal components that fit the often tight specifications of many manufacturing projects. The components must also be durable, so they support the finished product’s quality. We have provided this level of service and quality in our manufacturing division for decades. Many Silicon Valley companies have come to rely on us for fast and high-quality sheet metal parts. If you need a sheet metal fabricator, call us today (408) 295-2182
