The Square Tubular Shaft Helical Piles offered by Better Screw Co. are heavy‑duty foundation elements fabricated from structural carbon steel to ASTM A36 specifications. The helices are supplied in square shaft sizes of 2 in, 2.5 in, 3 in and 4 in, with plate thicknesses of either 3/8 in or 1/2 in. Each helix features a 45° sharpened and rock‑cut leading edge to aid penetration in dense soils. Corrosion protection is provided by a hot‑dipped zinc coating that conforms to ASTM A153.
In the foundation market, square‑tube shafts are preferred where torque control and visual deflection monitoring are required, and the typical industry practice is to use ASTM A36 steel for its predictable yield strength. The design eliminates over‑torquing concerns that are common with pipe‑style helicals, delivering efficient torque transfer during installation. A clear visual indicator on the shaft allows installers to observe torsional deflection, aiding precise torque application. Typical installation torque for piles of this size ranges from 5 kNm to 20 kNm, depending on soil conditions.
These piles are widely used by foundation contractors, geotechnical engineers and civil‑construction firms for deep‑soil anchoring in commercial, industrial and residential projects. Better Screw Co. lists the product for export to a range of markets, but specific minimum order quantities, pricing and lead‑time are not disclosed and should be confirmed directly with the supplier. Prospective importers are advised to request material certificates, coating verification and load‑test reports before finalising any purchase.
| Material | Structural Carbon Steel ASTM A36 |
| Shaft size range | 2" - 4" square |
| Plate thickness options | 3/8" or 1/2" |
| Helix leading edge | Sharpened and rock‑cut at 45° |
| Corrosion protection | Hot‑dipped zinc coating, conforms to ASTM A153 |
| Torque transfer characteristic | Efficient torque transfer, eliminates over‑torquing (typical) |
| Visual installation indicator | Clear visual indicator of torsional deflection (typical) |
| Typical axial load capacity | 20 kN - 150 kN per pile (typical for 2‑4" square shafts) |
| Typical installation torque range | 5 kNm - 20 kNm (typical) |
Better Screw Co. is located at No. 59 Gongyenan Road, Jinan, Shandong 250101, China. The company holds a “harbor” trust tier on the platform, indicating a moderate level of verification, but its response rate is recorded as 0 % with an average response time of 0 hours, suggesting limited communication activity.
The supplier markets structural carbon‑steel helices for deep‑soil anchoring and lists detailed product specifications, including material grade and corrosion coating, yet it does not provide additional certifications, production capacity or client references in the listing.
Square tubular shaft helical piles are heavy-duty foundation elements used for deep soil anchoring in commercial, industrial, and residential construction. Constructed from ASTM A36 hot rolled plate, these helices are available in 2 to 4 inch square shaft sizes with 3/8 or 1/2 inch plate thickness. Leading edges are sharpened and rock-cut at 45 degrees for efficient ground penetration. Ideal for challenging soil conditions, retrofitting, and projects where traditional driven piles are impractical. Common in export markets for foundation and geotechnical engineering applications.

Sourcing Square Tubular Shaft Helical Piles from Better Screw Co. - China Import Guide
Before placing an order, verify that the steel grade and zinc coating certificates are current and that the dimensions match the project’s design specifications. Request a copy of the ASTM A36 material certificate and the ASTM A153 coating report, and confirm the shaft size and plate thickness to ensure compatibility with load calculations. These documents provide the baseline assurance needed for structural reliability.
Importers should clarify logistics details such as the expected lead‑time, preferred Incoterms and shipping method. Because the listing does not disclose these terms, ask the supplier whether they can ship FOB Shanghai, CIF Ningbo or another port, and what the typical transit time is for containerised freight. Also confirm acceptable payment terms, such as a letter of credit or advance payment, to align with your procurement policy.
Quality control measures are critical for foundation components; arrange for a third‑party inspection either pre‑shipment or at the port of discharge. Request a load‑test report for the specific pile size you intend to purchase, and ensure that the inspection agency follows recognized standards such as ISO 17025. Finally, obtain a full packing list, commercial invoice and certificate of origin to facilitate customs clearance and verify that the received goods meet the agreed specifications.
