Helical Pier/helical Pile/screw Pile

The Helical Pier, also marketed as a helical pile or screw pile, is produced by Better Screw Company for deep‑foundation applications. The shaft is a seamless high‑tensile pipe that conforms to ASTM A500 Grade B, while the helices are fabricated from ASTM A36 hot‑rolled plate. Corrosion protection follows ASTM A153 hot‑dipped zinc coating, and the leading edge of each helix is beveled at 45 degrees. These components are shipped as complete pile assemblies.

ASTM A500 Grade B pipe typically offers a yield strength of 300 MPa and tensile strength around 460 MPa, values that are standard for high‑strength structural steel. ASTM A36 plate provides a minimum yield strength of 250 MPa, a common baseline for load‑bearing steel plates. The 45‑degree bevel increases the section modulus, giving greater resistance to torsion and improving load capacity, a design feature typical for screw‑pile foundations. Better Screw Company states that the piles are engineered for higher load capacities than conventional driven piles.

Primary users include geotechnical contractors, foundation engineers and offshore platform builders who require rapid installation and high axial capacity. Buyers usually discuss bulk quantities, Incoterms such as FOB or CIF, and payment methods directly with the supplier; exact MOQ and lead time must be verified. Shipping is generally arranged from ports in Shandong province, with containerised or bundled crate options. The Chinese origin gives access to established steel supply chains and export logistics.

Better Screw Company is based at No. 59 Gongyenan Road, Jinan 250000, Shandong, China. The supplier appears in the harbour trust tier and currently shows a 0.00 % response rate, meaning communications are routed through the platform’s messaging system.

The company produces round‑shaft helical piles using high‑tensile pipe and steel plate to ASTM specifications. It highlights the ability to provide piles with a 45‑degree helix bevel and enhanced section modulus, but does not disclose further corporate history, employee numbers or client references.
