Grinding
At Van Geenen’s, you will find a number of long-belt grinding machines capable of grinding sheets/plates in sizes up to 16,000 x 6,000 mm. The size of the sheets/plates is immaterial; however, the thicker the sheet, the more difficult it is to achieve the right finish. Van Geenen has a wealth of experience, especially when it comes to grinding and polishing thicker sheets/plates, the so-called hot-rolled or Quattro sheets/plates. If you want your product to have a certain visual aspect or be graded to a particular Ra value… Van Geenen is the answer to all your needs.
We can achieve any finish you desire: grinding to a particular grit size, high-gloss polishing or meeting a particular Ra value. ( Ra-value) Hot-rolled sheets – often abbreviated to 1D – are characterised by their thick and tough skin that contains irregularities, small dents and other damage.
To achieve the desired finish, it is of the highest importance to grind the surface in the right order. With our highly advances machines in combination with our know-how, we always manage to achieve the desired surface finish. Our machines have the additional advantage that the sheets/plates can also be ground widthways irrespective of the dimensions and the size of the plate.

Foils
As standard, all of our sheets/plates, strips, tubes and other products have an application of foil during processing to protect the material. Do you only want your material to be laminated? Once again, Van Geenen provides the solution. We have a suitable foil for any type of material and product to ensure that your products are protected during processing and arrive at their destination safely.
Our foil is highly suitable for cutting after grinding and polishing. Our laminating machine can apply foil to one or both sides of the product with a maximum size of 14,000 x 2,000 mm. Please contact us if you require different sizes.
