Thread rolling

Our Service

Cold tread rolling

Thread rolling is a cold plastic working process of round steel elements' surfaces, where the thread is formed by appropriately profiled rotating rolls.

This process is used in the production of bolts, threaded rods, elements for system formwork, and elements for scaffolding.

Advantages of thread rolling

  • Increased thread strength on tension, shear, and fatigue – ideal for loaded elements in construction.
  • Excellent surface roughness without chips and distortions, which improves corrosion resistance.
  • Fast process with high dimensional accuracy, reducing production time.

Thread rolling stands out as a cold plastic working method, offering higher strength and efficiency compared to traditional production techniques, which is crucial for threaded elements manufactured by Pamexpol.

Recommendations from Pamexpol

Thread rolling works best in the production of rods and formwork accessories, improving corrosion resistance.

The choice depends on the series and type of thread – for large projects, rolling is preferred due to efficiency.
