# Choose Your Signature Infill

Choose the infill next. The infill changes the line weight, maintenance routine, and whether the railing can follow curves.

{% hint style="info" %}
This step covers **Signature cable railing**. Express uses a smaller set of pre-configured options, so some choices shown here do not apply to Express.

If you choose Express, go to [Customize Your Express Cable Railing](/guides/planning/how-can-i-customize-my-cable-railing/choose-your-cable-system/customize-your-express-cable-railing.md) to review the standard option set. If you choose Signature, continue through the full customization process.

### How to choose infill

* Choose cable for the lightest visual line and the classic modern look.
* Choose stainless rod for curved sections, lower long-term adjustment, and maximum coastal durability.
* Choose Onyx Rod when you want a darker, bolder line without giving up the open view.
