Fiberglass Arch Pole

Product Overview

The fiberglass arch pole is an FRP support rod designed for arched greenhouses. It is made by pultrusion or pulwinding and has good bending elasticity and load capacity, which makes it a suitable support material for greenhouse and livestock housing construction. The arch pole is light, easy to bend and install, corrosion resistant and long in service life, and it replaces bamboo, timber and metal arch poles. Compared with bamboo and timber poles it does not rot, is not attacked by insects and lasts longer; compared with metal poles it does not rust, is lighter and is easier to install, and it needs no maintenance in long service. The smooth surface does not damage the covering film, so the structure is protected and the service life of the greenhouse is extended.

The pole has good and stable bending performance: it can be bent to shape on site, springs back strongly and does not break easily. A full range of specifications is available, with diameter and length customized to the greenhouse span, and used with longitudinal rails and clips the poles form a stable greenhouse frame.

Technical Specifications

Common diameters range from 10 mm to 20 mm, and lengths are made to the arch span and arch height. The pole is bent to shape on site to match the structure, has good elastic recovery and, combined with longitudinal rails, forms a stable greenhouse frame. It has high strength and good elasticity and carries the covering material and the snow and wind loads, while the smooth surface and stable dimensions make film fixing easy.

Different diameters and wall thicknesses are available to suit the load requirements of greenhouses of different spans. The ends are flat for connection to bases and clips, and longitudinal rails, channels and other accessories can be supplied to project requirements so that customers can build a complete greenhouse frame.

Production and Quality

The poles are formed continuously on the production line with tight control of fiber content and degree of cure, which gives stable elasticity. Diameter, length and surface quality are checked pole by pole before dispatch to confirm that there are no cracks or delamination and that no breakage occurs when the pole is bent on site. Strength is sampled and tested by batch, the data are recorded and kept on file, and an inspection report is supplied. Custom products are available to match the customer's greenhouse specification so that the poles fit the structure and installation goes smoothly.

The company has volume production capacity and can meet the quantity and lead time requirements of agricultural projects. Poles are packed in bundles with clear length markings, which makes transport and site handling easier and gives farmers and greenhouse builders a convenient purchasing service.

Applications

Fiberglass arch poles are widely used for the arched frames of vegetable greenhouses, flower greenhouses, mushroom houses, seedling houses and livestock sheds. They suit damp regions in particular, where they reduce maintenance cost and extend the service life of the greenhouse. The poles can be used with covering film, shade netting and other materials to meet the needs of different crops. Hebei Zhengche Trading Co., Ltd. provides design, customization and installation guidance for arch poles as a complete structural support solution for agricultural customers.

In protected cultivation, the corrosion resistance and elasticity of the fiberglass arch pole help farmers build stable, durable arch structures and reduce facility maintenance cost. With consistent product quality and complete service, the company continues to supply quality arch pole products to agriculture.

When installing the poles, set a sensible bending radius for the span of the house, fix both ends firmly to the bases, and use longitudinal rails, which markedly improves the overall stability of the frame.
