FRP Threaded Rods, FRP Bolts, and FRP Nuts: Durostone® composite fasteners are used in technical fields that have high demands on electrical, chemical and thermal properties. Durostone® FRP fasteners are based on glass fiber reinforced epoxy or polyester resin Systems with special additives and a special structure.
Compared to steel composite fasteners made of Durostone® are:

• Much lighter
• Electrical and thermal insulating
• Corrosion-resistant
• Resistant to aggressive media

Properties:

• Electrical properties: All Durostone® composite fasteners are electrically insulating and non-magnetic. Some qualities are moreover, partial discharge free up to a high electric field of strengths and especially non-tracking. They are excellent for use in transformers, in electrical engineering, in high-frequency, switching, and electrostatic powder coating equipment.
• Chemical properties: Durostone® composite fasteners are particularly resistant against aggressive fluids and gases, resistant to transformer oil and dielectric liquids and highly UV and weather resistant. They are in use, for example, in chemical equipment, flue gas desulfurization, and cable trays, onshore and offshore technology, seawater desalination, wastewater treatment, and cable trays.
• Thermal Properties: Compared to steel (15 - 58 W/mk) FRP threaded rods, bolts and nuts made of Durostone® have a very low thermal conductivity of 0.3 W/mk, and are therefore at the level of mineral wool, which is used in construction as insulation. They are ideal for use in refrigeration, HVAC and areas suitable for applications, where thermal bridges must be avoided.
• Lightweight: Durostone® composite fasteners have a density of 1.9 t 2 g/cm³ and thus weigh only about 1/4 of steel. They are well suited for applications where weight reduction is an important factor - for example, in-vehicle or the construction of nacelles for wind turbines.
• High tensile strength: Compared to threaded rods made of thermoplastic such as for example polyamide. Durostone® FRP threaded rods have a six-fold higher tensile strength.

Durostone FRP threaded rods, bolts, and nuts are used in:

• Flue gas desulphurization plant
• Onshore/offshore engineering
• Chemical plants
• Hydraulic engineering, sewage treatment plants, desalination of seawater
• Transformers, dry-type and oil-immersed
• Generators
• Switchgears
• Instrument construction, High-frequency Systems
• Traffic engineering
• Refrigeration and air conditioning
• Cable trays
• Electrostatic powder coating
• Electroplating plants
