SSP-RS114-400-Conventional spiral pile

Product Description

This model features a welded assembly consisting 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 treatment finishes of the product can be adjusted in accordance with customer construction drawings or engineering technical specifications. The actual load-bearing capacity shall be comprehensively verified by integrating soil stratification conditions, installation torque, embedment depth and engineering design criteria.

Product Features

Clear specification positioning

It adopts a combination of 114 mm (4-1/2 in) round tube steel shaft and 400 mm (16 in) helical flight, which serves as a standard display model for the engineering reinforced product line.

It features segmented equal-thickness helical flight structure, which enables precise control over flight thickness, dimensional tolerances and welding consistency.

Flexible flight configuration

Double or triple helical flights are optional, adjustable in accordance with soil layer conditions and load-bearing requirements.

The standard length ranges from 2.1 m to 3.0 m. Extension joints or custom lengths are available to meet various embedment depth requirements.

Defined applicable scenarios

It is mainly designed for commercial projects, high-load bearing foundations and general engineering applications, facilitating rapid application matching for overseas customer inquiries.

Multiple surface treatment finishes are available, including hot-dip galvanizing, black steel finish and custom protective coatings, making the product suitable for long-term outdoor service.
