Production of steel and stainless spirals

The endless spiral is the best and most economical solution should you need to convey large quantities of material in a short time.
Our company's sophisticated production technology, capillary checks and overall control on the finished product, besides over 30 years experience, allow Agrispiral to supply a proven quality product, a punctual service, in compliance with every customers' requirements.
Endless spirals can be either carbon steel or stainless steel. They are cold rolled.
The versatility of our production range allows us to produce spirals 40 to over 1000 mm outer diameter and in a gauge ranging from 3 to 10 mm.
Endless spirals can be applied in various agricultural and industrial activities thanks to its versatility and effectiveness, for instance:
cereal storage in silos, the production of snowplows, drills, mixing wagons, cement augers, feeders in heating installations using pellets and biomass, microproportioners, treatment of sludge and compactors, harvest bars for combined harvesters, oil production installations and wine making appliances, extruders.

A flexible spiral made from a high resistance strip gives high flexibility and resistance to torsional stress with consequent correct operation on curves.
Standard sizes

• Flexible spirals are mainly used in the automatic distribution installations of zoo-technical breeding centres and in pellet and biomass heating installations.
• Flexible spirals are the best possible solution to carry large quantities of material thanks to its properties in terms of flexibility, resistance to torsional stress and correct operation on a curve, too.
• The materials used to produce flexible spirals are:
- hardened high resistance steel
- stainless steel aisi 302

Printed spiral segments, as long as the pitch and in a constant thikness are used in the production of augers or endless screws, should it be impossible to use endless spirals due to high gauge, size or type of material required.
