SSP-RS89-350-Conventional spiral pile

Product Description

This model adopts a welded structure composed of round tube steel shafts and segmented equal-thickness helical flights, which facilitates mass production, dimensional tolerance control and project-specific customization The flight diameter, tube wall thickness, overall length, quantity of helical flights, connection methods and surface treatments of the product can be adjusted in accordance with customer drawings or engineering specifications. The actual load-bearing capacity shall be comprehensively verified based on soil conditions, installation torque, embedment depth and engineering design requirements.

Product Features

Clear specification positioning

Equipped with an 89 mm (3-1/2 in) round tube steel shaft and 350 mm (14 in) helical flight, it serves as a standard display model for the medium-load product line.

It adopts segmented equal-thickness helical flight structure, enabling precise control of flight thickness, dimensional tolerances and welding consistency.

Flexible flight configuration

Double flights are optional, adjustable according to soil layer conditions and load-bearing requirements.

Standard lengths range from 2.1 m to 2.5 m. Extension sections or custom lengths are available to meet various embedment depth demands.

Defined applicable scenarios

Primarily designed for medium-load foundations, soft soil subgrades and large decks, facilitating quick application matching for overseas customer inquiries.

Multiple surface treatments are supported, including hot-dip galvanizing, black finish and custom coatings, making it ideal for long-term outdoor service.
