STUD AND NUT
LEADFRP consists of a pultruded stud with threads cut in a glass mat reinforced outer layer (the center of the stud is unidirectionally reinforced for high strength) and a molded nut. LEADFRP does not possess the thread shear strength of steel, but has sufficient strength to be a viable alternative in structures where fastener corrosion is a concern or where metal fasteners are not permitted (antennae housings, computer equipment testing structures, etc.).
Stud & Nut Applications:
- Chemical Process Equipment
- Air and Water Pollution Equipment
- Marine Applications
- Low in Conductivity
- Cellular Antenna Mounts and/or Screens
- Computer Testing Facilities
Stud & Nut Features:
- Corrosion Resistant
- Easy to Fabricate
- Low Maintenance
- Low in Conductivity
- Transparent to Electromagnetic Waves
- Color Blends with Most Structural Materials
Stud & Nut Specifications:
Customized according to customer needs
At LEADFRP, we believe that fiber reinforced plastic (FRP) products are the choice of the future. Compared with traditional materials such as steel and aluminum, it has excellent performance and service life.
LEADFRP provides a series of high-strength fiber reinforced plastic products (FRP), which are designed and manufactured to provide long-lasting performance in highly corrosive environments, while having the advantages of light weight and high dielectric strength compared with traditional structural materials.
Since 2001, we have provided our customers with innovative, high-quality composite designs and materials through two strategic offices/factories located in the United States and China. It is here that we provide turnkey solutions to take your product from concept to design, to mold calculation, manufacturing, and finally to installation. [More about manufacturing]
We own 5 acres (20000 square metre) standard plants, 80 sets of advanced various manufacturing and machining equipments, 120 sets of assembly pultrusion production line, including one 1000 kN tensile strength machine and one 200 kN bending and torsion machine. We also can proceed basic property test of different kinds of composite insulation materials according to GB, ASTM, etc standards. Our products passed TUV Rheinland type test and UL type test.
LEADFRP strictly carry out standardized, scientific and normalized management mode. We fully implement ISO9001 quality management system, ERP managing system and 6S management mode through the whole service cycle of contract signing, production, process inspection, finished product ex-factory, after-sales service, which outstandingly reflect ‘Quality is the Life of Enterprise’. We have ISO9001, ISO14001 and ISO45001 identification.
