What Are Custom Fabricated Metal Buildings
Custom fabrication involves designing and constructing a building from scratch based on specific requirements. Poma and other custom fabrication companies like them design, manufacture, and install these facades on site.
Pros of Custom Fabrication
Buildings that take a custom fabrication approach have several pros:
1. Complete Customization
Custom fabrication allows for unparalleled design flexibility. You can create a building that fits your exact needs, from unique layouts to specialized features.
2. Higher Structural Loads
Custom fabricated metal buildings typically exceed local wind and snow load regulations. They are incredibly structurally sound.
3. Specialized Use
Structures created using custom fabrication are tailored to individual clients, making them a great option if you’re looking to do a highly custom project.
Cons of Custom Fabrication
1. Higher Costs
Because of the extra labor and materials used in custom fabricated metal buildings, it is typically a more expensive option.
2. Longer Lead Times
The design and construction process of structures created with custom fabrication is much more time consuming than pre-fabricated steel structures.
3. Complexity in Execution
On-site fabrication can be complex and require more oversight and expertise.
What are Pre-Engineered Metal Buildings (PEMBs)?
Pre-engineered metal buildings (PEMBs), or prefabricated structures, are designed and manufactured off-site and then assembled at the installation location. These structures come in a variety of standard sizes and styles, offering a versatile solution for a wide range of applications.
Pros of Pre-Engineered Metal Buildings:
Prefabricated metal buildings are beneficial to many customers looking to purchase a garage, carport, or shed for several reasons:
1. Cost-Effective
Prefabricated buildings are typically much more affordable because of streamlined manufacturer processes and reduced labor requirements.
2. Quick Installation
Pre-engineered components fit together seamlessly, significantly reducing construction time.
3. Durability
Made from high-quality galvanized steel, prefabricated metal buildings are strong and built for longevity. They can withstand harsh weather and require minimal maintenance.
4. Versatility
While not as customizable as custom fabricated options, prefabricated buildings still offer a range of sizes and configurations for various uses, such as carports, garages, and commercial structures.

Cons of Pre-Engineered Metal Buildings
1. Limited Customization
Whilst prefabricated buildings offer some flexibility, they can’t match the full range of custom options available with on-site fabrication.
2. Standardized Design
Prefabricated buildings might not fit unique architectural or aesthetic requirements as precisely as custom-built options.
When to Choose Custom Fabrication
Custom fabrication is ideal for:
- Projects requiring unique shapes, sizes, or features.
- Clients who need their buildings to match existing structures or specific architectural styles.
- Specialized industrial or commercial applications that demand tailored solutions.
When to Choose Pre-Engineered Metal Buildings
Pre-engineered metal buildings are perfect for:
- Budget-conscious clients seeking durable and reliable structures.
- Projects with tight timelines that require quick installation.
- Common applications like carports, garages, sheds, and workshops.

Frequently Asked Questions
What is the difference between custom fabricated and prefabricated metal structures?
Custom fabricated metal structures are built to specific requirements and designed to meet unique specifications. Each component is individually made, often allowing for more complex designs. Prefabricated metal structures, on the other hand, are pre-engineered and mass-produced in standardized sizes, making them more cost-effective but less flexible in design.
Are custom fabricated metal structures more expensive than prefabricated ones?
Yes, custom fabricated metal structures generally cost more due to the specialized design, manufacturing, and labor involved. Prefabricated structures, being mass-produced, tend to be less expensive and offer quicker installation, making them more bud
Can I modify a prefabricated metal structure?
While prefabricated structures offer limited modification options, you can often make some adjustments during installation or afterward (e.g., adding doors, windows, or other elements). However, the level of customization is far less than what is available with custom fabrication.
How long does it take to build a custom fabricated metal structure?
Custom fabricated metal structures usually take longer to complete since each piece must be designed and built specifically for the project. The timeline can vary based on complexity but may take several weeks to months from design to installation.
How long does it take to install a prefabricated metal structure?
Prefabricated structures are designed for quick assembly, and installation typically takes much less time compared to custom-built ones. Depending on the size and complexity, installation can often be completed in just a few days.
Which is the better investment in the long run?
It depends on your needs. If you need something highly specific that will last for years and are willing to invest more upfront, a custom fabricated structure may be the better option. For those looking for a more affordable and quicker solution, a prefabricated structure offers great value without sacrificing durability.
