Sheet metal fabrication
Are you looking for a reliable partner for sheet metal fabrication? De Graaf Metaalwerken provides custom sheet metal fabrication and processing in steel, stainless steel, and aluminum for construction, industry, and technical applications. From simple sheet metal parts to complex components requiring multiple processes: we work with you from the initial drawing or idea to deliver a solution that is technically sound, practical to manufacture, and perfectly suited to your project. Sheet metal fabrication is ideally suited for components where dimensional accuracy, finish, and flexibility in execution are critical.

Versatile
Sheet metal fabrication is used for a wide range of applications, from trim pieces and mounting plates to brackets, panels, and structural components.
Fully customized
We manufacture sheet metal parts based on your drawings, dimensions, and intended application. This ensures that every component is perfectly suited to the practical requirements of installation and use.
Suitable for multiple materials
Sheet metal fabrication can be performed on steel, stainless steel, and aluminum, depending on the load, environment, and desired appearance.
What does sheet metal fabrication involve?
Sheet metal fabrication is a general term for the process of transforming metal sheets into usable components, semi-finished products, or finished goods. In practice, this often involves a combination of processes, in which the material is first cut to size and then further shaped or assembled. It is precisely this combination that makes sheet metal fabrication so well-suited for custom projects in construction and industry.
Our areas of expertise:
- Cutting sheet material to the correct shape and size.
- Bending and forming sheet metal into profiles and technical components.
- Welding and assembling multiple parts into a single functional unit.
- Finishing touches for a neat fit and practical use.
- Production of single units, small batches, and recurring custom parts.


Why choose custom sheet metal fabrication?
With standard sheet metal or standard profiles, the design often has to be adapted to the available sizes and shapes. With custom sheet metal fabrication, it works exactly the opposite way: the part is tailored to its function, the available space, and the desired connection to other structural elements or technical components. This not only results in a neater end product but also prevents a lot of corrective work during installation or assembly. Especially in projects where precision, repeatability, and a high-quality finish are important, custom sheet metal fabrication offers clear added value.
Sheet metal fabrication for construction and industry
Sheet metal fabrication is widely used across various industries, including construction, mechanical engineering, installation technology, and interior design. Applications range from enclosures, brackets, and mounting plates to trim pieces, panels, and machine components. This makes sheet metal fabrication a versatile solution for companies seeking a reliable partner for custom technical work. For De Graaf Metaalwerken, this aligns well with projects where customization, flexibility, and a comprehensive approach are key.

Precise dimensions
In sheet metal fabrication, precision is key. Well-made sheet metal parts minimize on-site adjustments and make assembly or installation much more efficient.
Easy to use
Because components are delivered in the correct shape and size, the installation process on the construction site or in the workshop is faster and more organized.
For single pieces and series
Metal sheet fabrication is suitable for one-off custom parts, as well as for recurring parts within larger projects or production lines.
Custom vs. standard sheet metal
Standard sheet metal is a good starting point, but it is often insufficient for projects where fit, finish, or technical requirements play a major role. Custom sheet metal fabrication allows components to be produced exactly according to design specifications, including necessary shapes, cutouts, and joints. This eliminates the need for improvisation during assembly and results in a much more consistent final product. Especially when components need to connect to existing structures, systems, or machinery, custom fabrication is often the most efficient and reliable choice.
Flexibility in planning and execution
In construction and industrial projects, conditions can change rapidly. In such cases, it’s important to be able to adapt quickly in terms of dimensions, quantities, or execution. A company that handles sheet metal fabrication in-house can often adapt more quickly and better align with the project schedule. This is particularly valuable in B2B environments, because lead times, manufacturability, and clear communication directly impact the progress of the work.
Frequently Asked Questions About Sheet Metal Fabrication
What exactly is sheet metal fabrication?
Sheet metal fabrication involves processing metal sheets into components or finished products using techniques such as cutting, punching, bending, welding, and assembly.
What materials can be used in sheet metal fabrication?
Common materials include steel, stainless steel, and aluminum, depending on the application and the desired properties of the final product.
For which industries is sheet metal fabrication suitable?
Sheet metal fabrication is widely used in construction, mechanical engineering, building services engineering, interior design, architecture, and other industrial sectors.
What processes are included in sheet metal fabrication?
These include cutting, bending, forming, punching, welding, assembly, and various types of finishing.
When should you choose custom sheet metal fabrication instead of standard materials?
Custom solutions are particularly useful when standard sheets or profiles do not meet the required dimensions, shape, load capacity, or finish.
Is sheet metal fabrication suitable for one-off parts and small batches?
Yes, in the market, sheet metal fabrication is used for both individual custom parts and small- to medium-sized production runs.
Can you share your thoughts on design and engineering?
Yes, within the sheet metal fabrication industry, it is common for specialists to contribute their expertise regarding engineering, manufacturability, and the technical optimization of parts.
How is the price of sheet metal fabrication determined?
The price depends on factors such as the type of material, thickness, dimensions, the complexity of the machining operations, and the quantity.
How quickly can sheet metal fabrication be delivered?
Delivery times depend on the scope of the project, the materials used, and the complexity of the manufacturing process. In B2B environments, close coordination regarding scheduling and feasibility is particularly important.
Is sheet metal fabrication also suitable for visible applications?
Yes, sheet metal fabrication is also used in visible applications and architectural projects, provided that the material, finish, and dimensions are tailored to those purposes.
