A well-built metal enclosure begins with a well-defined application. Before a fabricator can determine the manufacturing processes, production schedule, and price, they need to understand what the enclosure must protect—and what it may encounter along the way.
Providing complete information when requesting a custom metal enclosure quote helps the fabricator identify potential challenges early. You may not have every detail finalized yet, and that's ok. Early collaboration with an experienced metal fabricator (like Accurate) helps keep your project budget on track. However, answering these five questions will give the conversation a strong starting point.
1. Where Will the Metal Enclosure Be Used?
As the old adage goes, “Location, Location, Location!" And just like in real estate, your next sheet metal enclosure's final home will play a vital role in how it's fabricated.
Consider whether the enclosure may be exposed to:
- Moisture
- Dust, dirt, or airborne debris
- Chemicals or corrosive materials
- Extreme temperatures
- Direct sunlight
- Vibration or impact
- Frequent cleaning or washdowns
The environment will influence the material, gauge, seams, hardware, and finish. If the enclosure must meet specific industry or environmental requirements, include those specifications with the RFQ.
2. How Will the Enclosure Be Accessed and Secured?
A metal enclosure must protect its contents while still allowing the right people to reach them. Think about how operators, installers, and maintenance personnel will interact with the enclosure throughout its service life. Discuss questions such as whether you will need removable drawers or specialized locks with your fabricator in advance.
Consider hardware as part of the enclosure—not an afterthought. Create a list of every component the fabricator may need to install or accommodate. This could include:
- Hinges and handles
- Locks or latches
- PEM® fasteners
- Weld nuts or studs
- Mounting rails and brackets
- Perforated shelves or drawers
- Gaskets and seals
- Cable-entry points
- Interior panels
Be clear about whether your company will supply the hardware or the fabricator will source it. Providing part numbers and installation requirements helps prevent uncertainty during quoting and production. This planning will make production easier.
3. How Will the Enclosure Manage Airflow, Heat, or Noise?
Many electrical and mechanical components generate heat during operation. Without an effective way to release that heat, the enclosure may contribute to higher operating temperatures or reduced equipment performance.
Ventilation options can include:
- Perforated metal panels
- Expanded grilles
- Fan openings
- Filter accommodations
- Strategically placed intake and exhaust areas
The right solution depends on the heat generated, the surrounding environment, and the required level of protection. Openings must allow sufficient airflow without unnecessarily exposing internal components to debris, moisture, or accidental contact.
Noise may also affect the design. Generator and equipment enclosures, for example, may require a balance of ventilation and sound control. Identifying these requirements before requesting a custom metal enclosure quote gives the fabricator a more complete picture of the application.
4. What Finish and Appearance Does the Enclosure Need?
As we've seen from questions 1-3, how your enclosure will be used, where it will be used, and airflow considerations all lead to the finish your custom sheet metal cabinet needs. The right finish will protect your investment for years. Powder coating is common for custom metal enclosures because it offers a durable finish and a wide selection of colors. Depending on the material and application, you may also consider other finishing options, including decals.
If the enclosure is part of a branded product line (such as a first aid cabinet), provide the appropriate color information to the project manager. Defining these details early helps the fabricator meet inspection requirements and avoid bringing in powder from the manufacturer (which could have long lead times).
5. How Many Enclosures Will You Need—and When?
And the most important question is…how many and when! From prototype to an initial production run and an ongoing program, you need to determine what sort of fabricator can handle your project.
Include as much information as possible, such as:
- Prototype or first-article quantities
- Initial production quantity
- Estimated annual volume
- Typical release quantities
- Required delivery date
Even an approximate forecast can help a fabricator recommend a more efficient production plan. It may also identify opportunities for scheduled releases, stocking programs, or consolidated material purchases.
What Should Accompany a Custom Metal Enclosure Quote Request?
Once you have answered all the questions about your next custom metal enclosure job, gather your answers and send them to the sheet metal fabricator. These typically include CAD files or detailed drawings, material specifications, and quantities. The more complete the package, the easier it is to develop a quote that reflects the project's actual scope.
