In the helical pile system, the cap is not only the connection point between the pile body and the superstructure, but also undertakes multiple functions such as transferring loads, matching structures, and simplifying construction.

Various connection methods: Adapt to various superstructures and meet different connection requirements

Flat Plate Cap: Commonly used in photovoltaic brackets, fences, signboards, etc., which can be connected by welding or bolting.

Threaded Cap: Used to connect with adjustable bases, suitable for structures with requirements for installation height, such as equipment foundations or modular buildings.

Gusseted Cap: Suitable for heavy industrial structures, it can effectively enhance the bending and shear resistance of the pile top.

Construction method affects design: The requirements of different projects for construction speed and convenience also determine the form of cap:

Bolt-on Cap: Easy to install, no on-site welding required, suitable for fast construction projects;

Welded Cap: More suitable for customized structures or projects that require on-site fine-tuning;

Some cap designs have notches, holes or marks to match the specific installation method.

Environment and appearance: both functionality and aesthetics

Depending on the use environment and external exposure conditions, the cap design also varies:

Hot-dip galvanized sealing cap: corrosion-resistant, suitable for outdoor or humid areas;

Decorative pile cap: mostly used in municipal and landscape engineering projects, not only structurally safe, but also visually effective.
