Marine Propulsion Stainless Steel Distributor

As a marine propulsion stainless steel distributor, Ram Alloys offers standard ABS-certified BSQ bar lengths, grades, and finishes, supplemented with complete on-site customization services for your marine needs. Boat shaft quality (BSQ) bars are a specialized type of precision shaft. Most commonly used in the marine and naval industries, BSQ bars are specially formulated and carefully treated to meet demanding performance requirements in challenging conditions.

While BSQ bar tolerances and performance standards are not typically as stringent as those for pump shaft quality (PSQ) bars, we understand that your project schedule demands on-time performance and full traceability. We stock boat shaft quality bars in the most common grades and sizes available for prompt shipment. Considerations for applications include engine horsepower, shaft speed (RPM), yield strength, torsional sheer, water temperature and corrosion resistance.
