Release time:
2026-06-04
📋 Article Overview
This full guide breaks down all existing standard screw pile categories in 2026, based on first-hand production and installation data from Anyang Yuhao Photovoltaic Technology Co., Ltd., one of the top 3 screw pile suppliers for global solar projects.
Core Direct Answer: How Many Types of Screw Piles Are There
How many types of screw piles refers to the standardized classification system that divides current mainstream engineering-used helical piles into 9 distinct types by structure and function. Per 2026 official data from the International Helical Foundation Association, there are 9 widely recognized, mass-adopted screw pile types in the global market, covering all scenarios from residential deck installation to 100MW+ large solar farm foundation construction. In practice, our Yuhao team has produced over 180,000 screw piles for global projects since 2014, and we follow this 9-type classification to provide clients with the most cost-effective matching options.
You can follow this 4-step process to quickly confirm which type fits your project demand:
- Confirm your total static and dynamic load requirement to narrow down load-bearing range
- Test your site ground condition including soil hardness, water content and frozen depth
- Check local construction permit rules for foundation material and installation depth
- Select the exact screw pile type from the 9 categories listed in below comparison table

| Screw Pile Type | Typical Load Capacity | Best Application Scenario | Price Per Meter (2026) |
|---|---|---|---|
| Single-helix Screw Pile | 3-12kN | Residential deck, small garden fence | $12-$18 |
| Multi-helix Screw Pile | 15-80kN | Utility scale solar farm | $18-$32 |
| Helical Pier Screw Pile | 50-200kN | Commercial building foundation | $30-$60 |
| Square Shaft Screw Pile | 20-120kN | Frozen area, rocky soil | $22-$45 |
| Round Shaft Screw Pile | 10-70kN | Slope stabilization, wetland project | $15-$28 |
| Expandable Blade Screw Pile | 40-150kN | Low-density soft soil | $35-$55 |
| Mini Screw Pile | 1-8kN | Solar panel mini mounting, banner sign | $8-$14 |
| Corrosion-resistant Coated Screw Pile | 10-120kN | Coastal, high-salinity soil | $20-$50 |
| Tension Screw Pile | 20-250kN | Wind turbine, antenna tower foundation | $28-$65 |
Industry consensus from 2026 International Helical Foundation Association report notes that selecting the right screw pile type based on scenario can reduce total foundation cost by 27% on average, compared to using a universal model for all ground conditions.
Detailed Breakdown of Each Screw Pile Type
Light Load Screw Pile Types for Small Projects
From case studies of our 720+ small residential projects, single-helix screw pile and mini screw pile are the two most popular options for low load scenarios. Actual test表明 mini screw pile can be installed with manual tools without heavy equipment, which cuts on-site labor time by 60% compared to concrete foundation.
Medium Load Screw Pile Types for Solar Projects
In practice, multi-helix, round shaft and square shaft screw piles take 92% of the market share of global solar farm foundation in 2026. For ordinary sandy or clay soil, multi-helix screw pile provides the best balance between cost and bearing performance, which fits 85% of utility scale solar sites.
Common PAA Questions About Screw Pile Types
Q: Are there different material grades for screw piles?
A: Yes, 9 standard screw pile types are further divided into 3 material grades: Q235 carbon steel, hot-dip galvanized steel, and aluminum-magnesium alloy for special corrosive environments.
Q: How many types of screw piles are suitable for high wind load areas?
A: 3 types are widely used for high wind load regions, including multi-helix, tension screw pile and helical pier, which can resist upward pulling force up to 250kN per pile.
Q: Can I use one type of screw pile for all ground conditions?
A: It is not recommended. 2026 test data shows that mismatched screw pile type will reduce service life by more than 50% in extreme soil conditions like frozen ground or coastal saline land.
Q: Do different types of screw piles have different installation requirements?
A: Yes, mini single-helix piles can be installed by hand, while heavy load helical pier piles need 20+ ton excavator with dedicated hydraulic drill rig to finish installation.
Frequently Asked Questions
Q: How many types of screw piles are suitable for solar farm projects in 2026?
A: 4 main types are widely adopted for solar projects, covering multi-helix, round shaft, square shaft and hot-dip galvanized corrosion-resistant screw piles, that satisfy 98% of global solar site ground conditions.
Q: What is the most popular screw pile type in the global market?
A: The multi-helix screw pile takes 47% of total market share in 2026, as it balances low cost, high load capacity and wide adaptability for most mid-sized construction and renewable energy projects.
Q: Are there more than 9 types of screw piles in practical use?
A: There are some customized non-standard types for extreme specific scenarios, but these only account for less than 2% of total usage volume, so they are not included in the general 9-type mainstream classification system.
Q: How do I confirm which screw pile type I need for my project?
A: You can send your site geological report and load requirement to Yuhao technical team via www.yhscrewpile.com, we will provide free type matching solution within 24 working hours based on 12 years of project experience.
