Q1: Can you ensure the holes on opposite sides of the tube are perfectly concentric and aligned?

A1: Yes. We utilize advanced multi-axis CNC machining centers and dedicated indexing fixtures to drill the holes. This guarantees strict concentricity and prevents any deviation or skewing, ensuring quick-release pins can pass through smoothly without friction.

Q2: What aluminum alloy grade is recommended for salt-water marine paddle applications?

A2: For marine and outdoor environments exposed to moisture or salt, we highly recommend 6061-T6 aluminum alloy accompanied by a high-grade anodized finish. This combination delivers exceptional structural yield strength and premium structural corrosion protection.

Q3: How do you handle sharp burrs inside and outside the drilled holes?

A3: Safety and quality are paramount. Every piece goes through a thorough mechanical deburring process after drilling. We clean both the outer edges and internal walls of the holes to ensure a completely smooth surface, protecting internal locking mechanisms or hands from scratches.

Q4: Can I order paddle bars with custom spacing between the holes?

A4: Absolutely. We offer fully customized manufacturing. You can specify the tube diameter, wall thickness, total length, hole size, and precise center-to-center pitch dimensions in your design file, and we will produce them accordingly.
