Save on shipping!

You can select smaller lengths and switch from freight to standard shipping and save!

How does selecting smaller lengths reduce shipping costs?

Reducing your order from an oversize item that requires expensive freight services to a smaller bundle makes it eligible for less expensive (and faster!) standard shipping services.

*Material tolerances will remain +/- 0.125".

Single Heat Lot Required

Why are heat lots important?

Heat lots ensure consistent metal properties, full traceability, and quality control, which are critical for precision and reliability in your projects.

By selecting "Single Heat Lot Required" option, we ensure all cut pieces are sourced from a single heat lot for consistency in material characteristics.
