BUILD TO LAST FOR CENTURIES WITHOUT MAINTENANCE
3. ADVANTAGES
Zero corrosion: 100% resistance to any & all harsh environmental factors, No rusting
High chemical resistance: Impervious to salt and other chemical attacks
High tensile strength: 2 x stronger than steel with tensile strength of 1000MPa
Light weight: 4 x (i.e. 73%) lighter than steel, (2100 Kg/m3 vs.7800 Kg/m3), Ease of transportation
Long life span: over 100s of years life span (GFRP) vs 25 years (Black Steel)
High fatigue life: 20 x higher resistance under cyclic loading (440,000 cycle vs. 40,000 cycle)
Non-Conductive, & Non-Electromagnetic: Ideal for high electrical field, e.g. power stations
Non-Magnetic: Ideal for hospitals, MRI rooms, laboratories & other uses
Low thermal conductivity: Makes it suitable for use in hot and cold environments, power plants
Low thermal conductivity: Makes it suitable for use in hot and cold environments, power plants
High bonding strength: Much greater bonding strength to concrete (20 Mpa)
Ease of cutting & handling: Faster & cheaper installation and site handling
Fire rated: Capacity to stand for more than 3 hours in direct fire with minimum concrete cover
Sustainable to environment: Environmentally friendly, less Green House Gases while transporting
High durability & performance: No maintenance required, No additional project cost, Major savings
Min. concrete cover: requires minimum concrete cover i.e. 38mm, (2 ½ x less cracking of concrete)
Detection by GPR: Easily detected by GPR
No waterproofing: For bridge decks, unique saving for future
