Yes, there are several price and cost differences between square and round shaft helical products, though specific pricing is determined on a project-by-project basis.
Key factors influencing the cost difference include:
- Material Costs: Square shaft helical piles generally require more steel per linear foot compared to round shaft alternatives, which can increase the raw material expense.
- Installation Efficiency: Round shaft piles often install faster in dense soils due to their lower torque requirements and slender profile. This can lead to lower costs by reducing equipment hours and labor. Conversely, square shafts often require larger, more robust equipment and higher torque, which may increase mobilization and operating costs.
- Maintenance and Longevity: Round shafts offer superior corrosion resistance because their continuous profile eliminates weld seams that typically exist on square shafts. While square shaft modifications (like treating welded connections) can add complexity and cost, the round shaft’s geometry may simplify long-term protection requirements.
- Project Complexity: Residential projects often utilize square shafts for their ease of handling with lighter loads, whereas commercial projects frequently utilize round shafts for high-torque, deep-embedment needs.
Because costs are heavily dependent on soil conditions, load requirements, and building code compliance, Helical Technology does not provide generic price lists. Instead, they provide custom quotes based on project-specific configurations and engineering analysis.
