Absorption of water and contaminants changes the way dynamic ropes perform. It makes ropes heavier, affects their stretch and rebound characteristics, and makes them more prone to damage and increased rate of wear. The advanced treatments developed by our engineering team utilize specialized techniques and technology to protect your ropes and ensure they perform well in all conditions.

Below is a rundown of Sterling's proprietary dry treatments for dynamic ropes.

DryCore™

Every Sterling dynamic rope for the last 20 years has featured our DryCore technology: This innovative process treats the all-important core fibers to prevent yarn-on-yarn abrasion and moisture absorption. This helps the fibers share loads more evenly and resist the negative effects of water. All of our dynamic climbing ropes have DryCore, even those that don’t go through the DeltaDry process. We think it’s that important.

DeltaDry™

DeltaDry is the process ropes go through to achieve the DryXP status. It encompassed DryCore treatment of the core strands, as well as the the process to chemically coat, treat and ‘bond’ the dry treatment coating to ropes at the finishing stage of rope construction. We coined the process/technology DeltaDry and the ropes that came out of it were DryXP, UIAA Dry.

DryXP™

DryXP™: Treated ropes that are certified to the UIAA Water Repellent standard of less than 5% water absorption.

Look for the DryXP or Dry labels on your favorite Sterling Rope. See below for details on which of our rope models feature what level of protection.
