2. Key Advantages of FRP Purlin

FRP purlins provide significant advantages over traditional metal purlins, making them an ideal choice for corrosive and weight-sensitive environments.

✔ مقاومة للتآكل

• Unlike steel, FRP does not rust, corrode, or deteriorate when exposed to moisture, chemicals, or harsh weather.

• Perfect for coastal, industrial, and chemical plant applications.

✔ Lightweight & High Strength-to-Weight Ratio

• FRP is up to 70% lighter than steel, reducing transportation and installation costs.

• يحافظ high structural strength, making it suitable for load-bearing applications.

✔ Low Maintenance & Long Service Life

• Requires minimal maintenance compared to steel, which needs regular painting or anti-corrosion treatments.

• FRP purlins have a عمر افتراضي يزيد عن 25 عامًا, significantly reducing replacement costs.

✔ العزل الكهربائي والحراري

• غير موصل للكهرباء, ensuring safety in electrical installations and power plants.

• الموصلية الحرارية المنخفضة, reducing heat transfer in hot or cold environments.

✔ Fire Retardant Options

• Fire-resistant FRP purlins are available with ASTM E84 Class 1 or 2 ratings.

• مناسب للتطبيقات التي تتطلب الامتثال لمعايير السلامة من الحرائق.

✔ Easy Fabrication & Installation

• يمكن أن يكون cut, drilled, and assembled without the need for welding or special tools.

• Reduces labor time and complexity compared to steel purlins.

3. Applications of FRP Purlin

FRP purlins are widely used in industries requiring corrosion resistance, lightweight solutions, and durability.

🔹 Industrial Buildings – Roofing and wall support in factories, warehouses, and workshops.

🔹 Chemical & Petrochemical Plants – Resistant to الأحماض والقلويات والغازات المسببة للتآكل.

🔹 البحرية والبرية – Used in shipyards, offshore platforms, and ports.

🔹 Cooling Towers – Supports cooling tower structures due to its high moisture resistance.

🔹 محطات معالجة المياه – Used in desalination plants, wastewater treatment, and reservoirs.

🔹 Agricultural Buildings – Corrosion-resistant purlins for livestock barns and greenhouses.
