Product Details



We produce helix with real helical shape, which can perform a clean rotation in soil and improve your screw pile installation.

Sectional helical plates, also known as sectional flighting or helices, are widely used in the fields of grain processing, food processing, mining, oil and gas, construction, solar farming, etc.. Due to the curved shape, it is normally very difficult to produce the perfect helix. Cold-forming solves this problem, producing a superior result, but at present only a few companies worldwide have this technology.


Employing our proprietary technology, we produce all types of cold-formed helical plates for a wide variety of industries, especially for screw pile foundations and screw conveyors. All types of raw materials, from carbon steel, low alloy steel and stainless steel to abrasion resistant steel, can be chosen to meet your needs. We are able to supply high quality helical plates at a competitive price to maximize your competitive advantage.


A well formed helical plate plays a key role in the screw pile foundation. We ensure its helical surface is normal to the axis or shaft, and the leading edge is parallel to the trailing edge. Its perfect helical surface will allow a clean rotation through the soil, for optimal installation and minimal soil disturbance.


Product Usage:

Apply to screw piles, screw conveyers, blenders, pile drivers, drilling machines, etc.. Cold-formed helices improve the efficiency when conveying materials and drilling.
