Fiberglass Round Bar

Product Overview

The fiberglass round bar is a solid rod produced by pultrusion from fiberglass reinforcement and a resin matrix. It has high tensile strength, good electrical insulation and good corrosion resistance. Diameter accuracy is high and the surface is smooth, and the bar can be machined to suit many applications, which makes it an important base material in many industries. Compared with a metal bar, a fiberglass round bar is light, does not conduct electricity and does not corrode, so its performance stays stable in damp and corrosive conditions over long service and maintenance cost is low. The bar is strong and resilient and carries considerable tensile and bending load, and it is widely used in the power, construction, agricultural and sports sectors.

Different resin systems, such as epoxy and polyester, can be selected to meet insulation, flame retardant, acid and alkali resistance requirements. The size range is complete and lengths can be customized, which makes purchasing and use convenient and makes the bar a good alternative to metal bar, bamboo and wood.

Technical Specifications

Common diameters range from 3 mm to 50 mm, supplied cut to length or in coils. Resin systems such as epoxy and polyester can be selected for insulation, flame retardant, acid and alkali resistance as required. Tensile strength is high, the elastic modulus is moderate, dimensions are stable, and the surface is smooth with no burrs, which makes cutting and secondary machining easy; the mechanical properties suit a wide range of applications.

Straightness is good and the ends are square, which makes cutting on site easier and reduces material waste. Cut-to-length bar in different diameters and lengths, and coiled small-diameter bar, are available to suit different production methods and applications.

Production and Quality

Fiberglass round bar is produced continuously on automated pultrusion equipment, with fiber content and degree of cure held stable and a small diameter tolerance. Before dispatch, appearance and dimensions are checked batch by batch to confirm that the product has no blisters, burrs or bowing and that mechanical properties meet requirements. Tensile strength and other properties are sampled batch by batch, the test data is recorded and filed, and a quality inspection report is supplied. Custom sizes and lengths can be produced and samples can be tested to confirm that the product suits the application.

The company has volume production capacity and can deliver quickly to meet customer requirements for quantity and lead time. Products are packed by size and shipped with clear markings, which makes acceptance and stock control easy and gives customers an efficient and dependable supply of bar.

Applications

Fiberglass round bar is used for electrical insulating tools, arrester cores, structural reinforcing rods, tent poles, kite frames, craft work and sports equipment, and it is also used for greenhouse frames and temporary building reinforcement, with stable performance and safe use. In damp and corrosive conditions it resists ageing and damage over long service. Hebei Zhengche Trading Co., Ltd. supplies fiberglass round bar in a range of sizes with matching products and gives customers in different industries dependable material support.

In the power, construction and agricultural sectors, fiberglass round bar combines insulation, corrosion resistance and high strength and is a practical replacement for conventional materials. With stable product quality and complete service, the company continues to supply fiberglass round bars to its customers.

Fiberglass round bar can be cut, drilled and machined at the ends to suit the application, and it performs better when used with connectors and bases. Specific diameter and length requirements can be given at the time of purchase and the company will supply to order.
