Continuous spirals
Select the type of a spiral you need:
Shaftless spirals - robust
These spirals have constant thickness of a material all over its length.

Steel spirals are also known as metal spirals, continuous flighting or shaftless spirals. We produce these spirals with our own technology and thank to that we can achieve the best results in quality. Wide options of production range of thickness and diameters gives us opportunity to supply the right spiral for you.
Metal spirals are produced from flat bars, on the basis of technical specification from our customer. It’s important to know the exact data of your spiral - outside diameter, pitch, inside diameter, thickness and type of required material. We also need to know if the spiral will be mounted on shaft, or it will be used for shaftless spiral conveyor. This is important for prioritizing the inner or outer diameter.
We can offer you robust spirals with constant material thickness or spiral composed from two flat bars welded together or spirals produced from metal stripe with conical thickness and international standard measures.
Shaftless spirals or continuous flighting welded on shaft are often used in many industries for handling material in conveyors for drilling or pressing machines etc.
You can find them almost in every industry: constructions, agriculture, waste water treatment, energy, wood processing, pharmaceutical, chemical or heavy industries.
