Durable connections for eternity
The construction industry primarily demands screws made from stainless steels because corrosion resistance is the driving factor. Even these could be subject to inter-crystalline corrosion, stress fractures, vibration cracks, or contact corrosion.
With this in mind, KOLB produces special screws for the construction industry, tunnel construction, and swimming pool construction that minimize the corrosion risk because of their physical characteristics.
We also produce screws with large head volumes such as hammerhead screws with hooks of profiles under the heads to provide anti-torsion protection.
