Custom metalwork
Custom metalwork is indispensable for a sleek, durable finish on roofs, facades, steel structures, and technical installations. At De Graaf Metaalwerken, we produce custom metal sheet metal work in steel, stainless steel, and aluminum, exactly according to your drawings or dimensions. Whether it concerns simple corner profiles or complex, multiple sheet metal work, we think along with you, deliver quickly, and provide sheet metal work that fits immediately and is ready for installation.

What is custom metalwork?
Custom metalwork is sheet material that is bent into a specific shape, such as L, U, or Z profiles, or more complex shapes. By bending the sheet metal to exact specifications, profiles fit seamlessly onto roof and facade details, steel structures, or machines. This reduces the need for fitting and grinding work on the construction site and minimizes the risk of errors, leaks, or misaligned connections.
Who is sheet metal work suitable for?
Custom metalwork is ideal for professionals looking for reliable and dimensionally stable sheet metal. From finishing profiles for construction and roofing technology to sleek components for interior design and mechanical engineering: our flexible production always delivers the desired precision. Whether for one-off projects or recurring series, we offer the right solution for every production environment.
Applications of custom metalwork
Custom metalwork is used in a wide variety of projects. From finishing roofs and facades to covering profiles for steel and concrete structures. They also offer the ideal solution for components such as brackets, protective plates, and interior details. Because each profile is cut to size, the flashings always fit seamlessly with your specific details and material structure.
Advantages of custom metalwork
Custom metalwork offers many advantages over standard profiles or separate plates. By working from drawings, you get exactly the shape and size that your detail requires. This saves time during assembly, reduces sawing and grinding work, and results in a much cleaner finish.
Advantages include:
- Perfect fit: Profiles connect directly to the substructure and finish.
- Efficient installation: Less fitting, measuring, and correcting on site.
- Freedom in design: From simple to complex profile shapes possible.
- Customized material selection: Steel, stainless steel, or aluminum, tailored to function and environment.
- Suitable for single pieces and series: Ideal for detailed solutions and repetitive work.


Why choose for custom metalwork?
With custom metalwork, you let the design take the lead, rather than being dependent on standard commercial sizes. Profiles are tailored to insulation, cladding, connection details, and mounting points. This means fewer makeshift solutions, less chance of open seams, and a neater end result. Especially in visible areas — such as facades, entrances, stairwells, or interiors — custom metalwork creates a calm interplay of lines and a professional look.
Flexibility in implementation and planning
Flexibility is key at De Graaf Metaalwerken. Need to change a size, add an extra fold, or get extra profiles fast? Since we do our own production and engineering, we can switch gears quickly. We tailor production and delivery to your schedule, so your metal stamping is ready right on time and you can keep building without any delays.

Contributing ideas from the drawing board stage
We kijken graag met je mee naar details en tekeningen. Denk aan buigradius, overlap, waterafvoer en bevestiging, zodat het metaal zetwerk niet alleen maakbaar is, maar ook praktisch en duurzaam in de praktijk.
Consistent quality
By working with experienced craftsmen and professional machines, we consistently deliver dimensionally stable metal stampings. Especially in series production, it is important that parts are exactly the same and remain interchangeable.
Peronal advice
You have a single point of contact who is familiar with your project and can respond quickly to questions or changes. This makes the process clear and prevents miscommunication.
Custom metal work and choice of materials
Custom metalwork can be done in various materials, depending on the application and environment:
- Steel: robust and suitable for load-bearing or less visible components.
- Stainless steel: ideal for corrosion-resistant, hygienic, or representative applications.
- Aluminum: lightweight, dimensionally stable, and suitable for many facade and finishing details.
Together, we will determine which material best suits your project in terms of load-bearing capacity, appearance, and lifespan.
Easy-to-install solutions
When designing metal fittings, we take into account accessibility, overlap, and screw or mounting holes. This allows technicians to work faster and reduces the risk of errors during assembly.
Frequently asked questions about custom metalwork
What is custom metalwork exactly?
Custom metalwork is sheet metal that is bent into a specific shape, such as L, U, or Z profiles, or more complex shapes, entirely according to your specifications.
For which projects is custom metalwork suitable?
For almost all construction and industrial projects: from roof and facade finishing to interiors, machine construction, and technical installations.
Which materials do you use for custom metalwork?
Depending on the application, we use steel, stainless steel, or aluminum. Together, we determine which material best suits your requirements.
Can I submit my own drawings for custom metalwork?
Yes, you can submit drawings or dimension lists. We will check them, contribute ideas about details, and translate everything into a print-ready layout.
Do you do both one-offs and series production?
Certainly. We supply both unique profiles for specific details and larger series for repetitive work within a project.
How quickly can you deliver custom metalwork?
De levertijd hangt af van de omvang en complexiteit van de order. We stemmen productie en levering altijd af op jouw planning en kunnen met strakke deadlines meebewegen.
