Industrial walkways provide safe access to equipment, elevated platforms, rooftops, and maintenance areas. Choosing the right material affects safety, maintenance costs, and long-term performance. Today, FRP walkways and steel walkways are the two most common options for industrial access systems. Both offer unique advantages, but each performs differently depending on the operating environment.
This guide compares fiberglass and steel walkways across the factors that matter most, including strength, corrosion resistance, maintenance, cost, lifespan, and application suitability.
What are FRP Walkways?
FRP walkways are access systems manufactured from fiberglass reinforced plastic. They combine fiberglass reinforcements with durable resin systems to create lightweight yet strong structures.
A typical system includes:
- FRP walkway grating
- Structural fiberglass profiles
- Handrail systems
- Support members
- Connection hardware
Unlike steel, fiberglass does not rust and requires very little maintenance. These properties make fiberglass walkways popular in chemical plants, water treatment facilities, marine environments, and many other corrosive applications.
