How to Protect Bollard Substrate from Corrosion Under UHMWPE Pads

Overview

This guide covers the practical steps to protect bollard substrate from corrosion under uhmwpe pads. JSLT Marine produces engineering plastic components in UHMWPE, HDPE, PA, POM and PTFE — full-process fabrication from raw sheet to CNC-machined parts.

Step-by-step procedure

1. Inspect substrate before mounting. Sandblast and prime steel bollards before pad installation.
2. Use marine-grade coating. Two-pack epoxy or zinc-rich primer beneath pad.
3. Add drainage gaps. Spacer washers create air gap to drain trapped seawater.
4. Monitor annually. Lift pad annually to inspect and re-coat substrate.
5. Document and certify. Record inspection results; certify annually for port operations.
