Aftertreatment of sheet-metal parts

From a simple sheet part to a fully finished and assembled product with the right aftertreatment. We also provide the correct surface treatment and final finishing as part of the total product, either in-house or in cooperation with a few specialised partner companies. Which aftertreatment is right for your semi-finished product? Depending on the application of the end product, we are happy to help you make the right decisions!

Finishing, surface treatment & aftertreatment

Ensuring that a product no longer has any sharp edges? Or extend the life of the sheet-metal part? The type of finishing we have to carry out for you is closely related to the application of your final product. A sheet-metal part that is exposed to extreme conditions, chemicals or seawater requires a different aftertreatment than a profile in a ventilation shaft. The condition of the material, the construction and the shape are also factors that count. Giving the right metal finish helps to ensure that the semi-finished product meets your expectations. As part of a total product, we offer various finishing treatments.


When there are sharp edges left on the product after laser cutting, our automatic deburring machines strip these sharp edges from the products. We cut using advanced machines equipped with the latest techniques, based on both fibre and CO2, so our cutting is done with minimal burring. However, burring may still form on a product, especially in thicker sheet material. For that reason, we offer as part of our service various machine deburring techniques.

Barrel tumblers

Deburring barrel tumblers are ideal for small particles, with vibration and small stones rounding off the sharp edges.

Pickling / Passivation

Has the oxide film been damaged? Then we repair it by pickling and passivation, so that the oxide film becomes passive once again.


Grinding is an operation in which we treat the surface of the material with granules. This creates an aesthetically pleasing smooth and shiny effect.


Has the material surface already been ground? Then we make the surface even smoother and shinier by polishing the metal or stainless steel. This also increases corrosion resistance.

Bead blasting | in-house

To remove weld discolouration and make the material more resistant to rust, we blast the product in our special blasting cabinet with small glass beads. This completely seals the surface of the material.

Powder coating

Powder coating gives the product a great finish and a longer life. We work together with renowned partners for this purpose, so we will also arrange this final finishing for you if you wish.


This surface treatment on an aluminium surface provides your product with extra hardness and wear resistance. In cooperation with various specialized companies we will anodize your aluminium sheet parts as per your requirements.

Addition to delivery programme

Aftertreatment of semi-finished products is an addition to our delivery programme. We offer this as part of a product or construction. Are you looking for a supplier for just processing your own product? If so, we would be delighted to refer you to one of our specialist partners.

Why subject sheet metal to aftertreatment?

Finishing, surface treatment & aftertreatment

Ensuring that a product no longer has sharp edges or extending the life of the sheet-metal part are all reasons for aftertreatment. Which aftertreatment we carry out for you is closely linked to the application of your end product. A sheet-metal part that is exposed to extreme conditions, chemicals or seawater requires a different aftertreatment than a profile in a ventilation shaft. In addition, operations such as pressing and welding lead to damage to the oxide film of stainless steel, resulting in corrosion (rust). The right aftertreatment allows us to increase the life span of these products. Finally, aesthetic factors also count, of course. You want a smooth, visually pleasing and fully finished semi-manufactured product that you can further build on?

The benefits of our aftertreatment

Stainless steel is our specialism

Not only are our machines and software a key part of our stainless-steel specialism, but our employees are also an indispensable factor in our success. Whatever end product you use our specialism for, we are happy to make our craftsmanship part of your process.

Collaboration in the chain

Since 1986, we have been a close-knit family business characterised by continuity and reliability. We work in an open and informal atmosphere and find involvement very important. Not only within our company, but also with our customers and suppliers. With our years of experience in the market, we have acquired some great partners. We also work together with our partners in the field of surface treatments. We provide you with a fully finished product, and you keep a single point of contact.

Smart manufacturing process, from a sheet-metal concept

Setting up a product completely from a sheet-metal concept saves time and money. We arrive at the ideal manufacturing process by thinking carefully about the correct sequence of machining operations, the use of open sheet-metal profiles in constructions and the consequences of heat input during the welding process, as well as other factors. Our aim is greater efficiency while maintaining quality. The right finish completes the picture!

Advice as added value!

You know your end product and your market through and through. We have the knowledge and resources for an optimal manufacturing process of the stainless-steel semi-finished products that are essential for this. We prefer to bring the best of both worlds together as early as the engineering phase. By being involved with you and your project as early as possible, we like to partner with you about how best to realise the finest end product together. A small modification can already save a lot of money. In terms of not only the number of operations, but also time or material consumption.
