• No painting, sealing, or coating required, unlike steel or wood.

• Resistant to mold, mildew, and termites.

3.5. Easy Fabrication and Installation

• Can be easily cut, drilled, and joined using common tools.

• No welding required, reducing installation complexity and costs.

3.6. Sustainable and Cost-Effective

• Longer lifespan than metal or wood, reducing the need for frequent replacements.

• No expensive corrosion treatments required, minimizing maintenance costs.

4. Disadvantages of FRP Corner Angle

4.1. Higher Initial Cost

• FRP is more expensive than steel or aluminum per unit.

• However, long-term savings on maintenance and replacement justify the investment.

4.2. Lower Stiffness Compared to Steel

• More flexible than steel, requiring additional support in load-bearing applications.

• Not ideal for high-load structures without reinforcement.

4.3. UV Degradation Without Protection

• Exposure to direct sunlight can cause surface fading or slight degradation.

• Requires UV-resistant coatings for long-term outdoor use.

4.4. Limited High-Temperature Resistance

• FRP can soften above 150-200°C, unlike steel, which withstands extreme heat.

• Fire-retardant versions are available but come at a higher cost.

4.5. Recycling Challenges

• Difficult to recycle due to its composite structure.

• Limited eco-friendly disposal options.
