Today let's us talk about details:
Fiber Reinforced Polymer or FRP is formed by reinforcing fiber materials such as glass fiber, carbon fiber, aramid fiber, etc., and the matrix material is subjected to a forming process such as winding, molding or extrusion. Composite material. Common fiber-reinforced composites are classified into glass fiber reinforced composites (GFRP), carbon fiber reinforced composites (CFRP), and aramid fiber reinforced composites (AFRP), depending on the reinforcement.
The Advantages of FRP manhole cover
Excellent performance: Similar hard property as cast iron, while have a overwhelming advantage on stretch recovery.
No theft value: Anti-rust, corrosion, water, dust, well sealed
Non-electricity conduction and non-heat conduction.
High load capacity:Load capacity are A15, B125,C250,D400
Light weight:The weight especially SMC manhole cover is lighter than cast iron and concrete.
Durable service life:More than 30 years service life without crack and color fading.
It is used in various fields such as civil buildings, bridges, highways, oceans, hydraulic structures, and underground structures.
