Based on our business experience, we offer robust spirals from 25 mm to 800 mm. Dimensions are usually immediately available from our warehouse.

RL and RLN spirals (robust and robust stainless steel) are sold in production lengths, in case of exact length requirement different from production length, we charge preparation fee + weld.
