Custom sheet metal work
De Graaf Metaalwerken is your partner for custom sheet metal work for construction, industry, and technical applications. With our modern bending machines and years of experience, we bend sheet metal in steel, stainless steel, and aluminum exactly according to your drawings, from simple angles to complex profiles. Whether it concerns facade finishing, roof edge profiles, consoles, cover plates, or specials: we think along with you in detail, deliver quickly, and ensure that your bending work fits perfectly with the rest of the construction.

Wat is custom sheet metal work?
With custom bending, we bend sheet metal into the desired shape, such as U, L, Z, or special profiles, fully tailored to your project. This ensures tight connections, less assembly work on site, and a sleek, professional finish for facades, roofs, stairs, steel structures, or machinery.
For who is custom sheet metal work?
Custom sheet metal work is ideal for contractors, steel fabricators, interior builders, facade builders, and installers who need reliable custom parts. Industrial companies and machine builders also benefit from precision sheet metal work that can be used directly in production or assembly.
Applications of custom sheet metal work
Customized metalwork is used in countless architectural and industrial situations. Examples include: roof and facade finishing, cover profiles and edge finishing on steel structures, consoles, brackets, and support profiles for installations.
Advantages of custom sheel metal work
Custom sheet metal work offers many advantages over standard profiles available on the market. You get exactly the size and shape that the design requires, which reduces errors on the construction site and improves the finish. In addition, you can tailor the type of material, sheet thickness, and finish to the load, environment, and aesthetics. This makes custom metalwork a sustainable, efficient, and cost-effective choice for professional users.
Advantages include:
- Perfect fit: Less on-site fitting, less sawing and grinding.
- Efficient assembly: Parts fit together directly, reducing assembly time and costs.
- Freedom in design: Profiles exactly according to drawings, even in complex shapes.
- Customized material selection: Steel, stainless steel, or aluminum tailored to function and environment.
- Suitable for series and single pieces: From a single unique profile to recurring series work.


Why choose for custom sheet metal work?
With custom sheet metal work, you translate the design one-to-one into reality, instead of having to adapt the design to standard sizes. We work with you during the engineering phase to consider dimensions, bending radii, and mounting options, ensuring that the profiles are both technically and visually correct. This prevents surprises during installation and ensures that details such as joints, corners, and connections are sleek and durable.
Flexibility in implementation and planning
At De Graaf Metaalwerken, flexibility is key in both execution and planning. We can respond quickly to changes in dimensions or additional orders without compromising on quality. Thanks to our own workshop, we can tailor production and delivery to your construction schedule, ensuring that custom metalwork is delivered exactly when you need it—ideal for projects with tight deadlines.

Peronal advice
We will review drawings, detailed solutions, and material choices with you to ensure that your custom sheet metal work is technically and practically perfect.
Custom sheet metal work vs. standard profiles
Standard profiles often force you to compromise: extra overlap, seams, filler strips, or grinding to make them fit. With custom-made flashings from De Graaf Metaalwerken, profiles are made exactly according to the design, so that they fit existing structures, insulation packages, and facade materials. This results in a visually cleaner result, less chance of leaks or rust spots, and a more efficient installation process. Custom metalwork makes all the difference, especially in projects where aesthetics and detail are important, such as visible work in facades, stairwells, or interiors.
Easy-to-install solutions
When designing custom-made formwork, we take into account fixing points, overlap, and accessibility to ensure that assembly on the construction site runs as smoothly as possible.
