DynaGuard STA : GFRP Moduled Gratings
Physical Properties:
Density: Varies depending on the resin matrix and reinforcement, typically around 1.6 – 2.0 g/cm³.
Thermal Conductivity: Low thermal conductivity compared to metals.
Expansion Coefficient: Minimal expansion and contraction with temperature changes.
Electrical Properties:
Non-Conductive: FRP gratings are non-conductive and offer excellent electrical insulation properties.
TECHNICAL & PHYSICAL PARAMETERS
Mechanical Properties:
Tensile Strength: Typically in the range of 20,000- 30,000 psi (138 – 207 MPa).
Flexural Strength: Around 25,000 – 40,000 psi (172- 276 MPa).
Compressive Strength: Approximately 20,000 – 30,000 psi (138 – 207 MPa).
