FRP Box Beam

Our advanced composite FRP Box Beam  suitable for major load bearing structural applications. The modular construction system consists of a small number of interlocking fiber reinforced polymer (FRP) structural components produced by the pultrusion process. The main building panels are 3.15″ (80mm) thick and either 23.68″ or 13.70″ (601.5mm or 348.0mm) wide and feature a cellular construction. Through the use of toggles and/or hangers, panels can be connected to one another, to 3-way connectors, or to 45 degree connectors.

This uniquely designed system of interlocking components makes it possible to design fiberglass structures at significantly lower costs for a broad range of construction applications. structures can be designed to be shipped flat to the job site.

Our system of five interlocking components manufactured of pultruded fiberglass reinforced polymer. The system combines manufacturing simplicity with an almost unlimited number of configurations. The panel features integral grooves into which a toggle is inserted during assembly. 3-way and 45 degree connectors allow the system components to turn corners and facilitate the joining of walls or sides. For added flexibility, the system also includes a hanger and an end cap. Joints between panels and connectors are bonded during final assembly. Adhesive is applied along the length of the panel and connector. The toggle, to which adhesive is not applied, is then inserted as an assembly aid to mechanically secure the components and create even pressure along the length of the joint until the adhesive between the structural components cures.

The pultruded fiberglass skin is available in either a premium polyester or a vinyl ester resin. Both resin systems provide flame retardance (UL 94 V-0). Vinyl ester is utilized in extreme corrosive applications. A synthetic surfacing veil is incorporated into the skin to improve weathering, corrosion resistance, and resistance to degradation from ultraviolet rays. Resistance to weathering can be further enhanced by the application of a polyurethane paint. The core material, which provides the insulation value, is a rigid closed-cell urethane foam. The ends of the panels must be encapsulated or coated with a resin similar to the skin resin to maintain the corrosion and weather resistant qualities of the total panel

Traditional panel have their place. But for harsh, corrosive environments, FRP is a smart choice. Here’s how FRP compares to several traditional options

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.
