FRP Round Tube

Product Overview

The FRP round tube is a round-section profile produced by pultrusion. It is light, strong, corrosion resistant and electrically insulating, and it is a common base material for building FRP structures. The surface is smooth and the dimensions are stable, the tube can be cut to any length for the application, and it is easy to work, which makes it a practical replacement for metal round tube. Compared with a conventional metal round tube, an FRP round tube needs no protective coating and does not corrode in damp, acidic or alkaline conditions over long service, so maintenance cost is low. The product does not conduct electricity or carry magnetism, which makes it safer in electrical and special environments, and it is widely used in industry, agriculture and municipal construction.

The FRP round tube has a regular section and good concentricity, so load is carried evenly and flexural strength is high enough for the loads of normal service. Wall thickness and diameter can be selected as needed, so the design stays flexible and the customer can choose an economical and sensible material configuration for the structure.

Technical Specifications

Common outside diameters range from 20 mm to 150 mm, with wall thickness from 2 mm to 10 mm, and lengths are supplied cut to size. The resin system can be selected for the service environment, with flame retardant, acid and alkali resistant options, and the standard colours are grey and yellow, with others available to order. Mechanical properties are stable, flexural and compressive strength meet structural requirements, the surface is smooth and free from twist, and dimensional tolerances are small, which makes cutting, drilling and jointing straightforward.

The ends are square, which makes cutting and assembly on site easier, and elbows, tees and other fittings can be used to build a variety of structures. Cut-to-length products in different lengths reduce splicing on site and improve construction efficiency.

Production and Quality

Round tube is formed continuously on pultrusion lines, with even fiber distribution and full cure, so properties are stable. Before dispatch, outside diameter, wall thickness, roundness and surface quality are checked batch by batch to confirm that the product has no blisters, cracks or bowing and meets structural requirements. Mechanical 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 project.

The company has the capacity for volume production and can meet project requirements for quantity and lead time. Products are packed by size and shipped with clear markings, which makes acceptance and management easy and gives customers a convenient and efficient profile purchasing service.

Applications

FRP round tube is used for guardrail handrails, flagpoles, support poles, tool handles, frame posts and greenhouse brackets. It suits damp and corrosive environments in particular, with a long service life and low maintenance cost. The tube serves as structural support, protection and decoration, and with other FRP profiles it forms a complete structural system. Hebei Zhengche Trading Co., Ltd. supplies FRP round tube in a range of sizes with matching connectors and gives structural projects dependable material support.

In industrial and agricultural facilities, FRP round tube is an economical replacement for metal tube thanks to its corrosion resistance and freedom from maintenance. With stable product quality and prompt supply, the company continues to provide customers with FRP profiles.

When choosing an FRP round tube, select the diameter and wall thickness for the load and span at the point of use, and confirm that the resin system suits the site environment, so that the structure stays safe and reliable in long-term service.
