FRP rod advantages
- Light weight, high strength— easier to transport and install with standard tools
- Corrosion resistant— won’t rot or rust and absorbs minimal moisture
- Chemical resistant-mild acid-alkali proof
- Humidity resistant— no shrinking or swelling
- Impact resistant — fiberglass mat distributes the load to prevent surface damage
- Safety — won’t conduct electricity, and non-slip surfaces are available
- Long-lasting— lower lifetime cost than traditional building materials
- Low thermal conductivity — does not easily conduct heat or cold
- Non-electrical conductivity, with non magnetic property
- Fire retardant(selected)
Fiberglass rod Applications:
• Plant and tree stakes
• Tent poles
• Soccer poles
• Marker flags
• Marine masts
• Radio antennas
. Hanging rod for flour mill plansifter
