BEIHAI YUEDA FRP PRODUCTS
The application prospects and current status of pultruded fiberglass products in our country.
Release time:
2019/01/14
The pultrusion molding process is a special process in the fiberglass molding technology, suitable for producing fiberglass profiles with the same cross-sectional shape, such as rods, tubes, solid profiles (I-shaped, U-shaped, square profiles) and hollow profiles, etc. Its advantages are: 1. The production process is continuous, ensuring stable product quality and good repeatability; 2. The content of reinforcing materials can be adjusted according to requirements, resulting in high product strength; 3. The longitudinal and transverse strength of the products can be adjusted to meet different usage requirements; 4. It can produce products with complex cross-sectional shapes to meet the requirements of special occasions; 5. The products have good integrity, and the utilization rate of raw materials is high.

1. Application prospects of domestic pultruded fiberglass products
Due to the many advantages of the pultrusion fiberglass molding process, pultruded fiberglass products are widely used in various fields, with the main application areas being as follows:
1. Chemical and anti-corrosion market
The chemical and anti-corrosion market is a major user of pultruded fiberglass, with successful applications including: fiberglass sucker rods, cooling tower supports, offshore oil extraction equipment platforms, walking grids, stair handrails and supports, structural supports in various chemical corrosion environments, and cover plates for water treatment plants.
2. Electrical market
The electrical market is the earliest application market for pultruded fiberglass, with successfully developed products including: cable trays, ladders, supports, insulated ladders, transformer isolation rods, motor slot wedges, electric rail third rail protective plates, optical fiber cable core materials, etc.
3. Construction market
In the construction industry, pultruded fiberglass has penetrated the market of traditional materials, such as: doors and windows, concrete formwork, scaffolding, stair handrails, partition wall panels, reinforcement materials, decorative materials, etc. There is significant development space for fiberglass products in reinforcement and decorative materials.
4. Road traffic market
Successful applications in the road traffic market include: highway guardrails, road signs, pedestrian overpasses, sound barriers, components for refrigerated vehicles, etc.
5. Rural market
Successful applications in the rural market include: livestock pens, poultry house fences, greenhouse frames, supporting components, trellises, water troughs, etc.
6. Consumer entertainment market
The consumer entertainment market is a market with great potential, with currently developed applications including: fishing rods, tent poles, umbrella frames, flagpoles, tool handles, lamp posts, railings, handrails, stairs, radio antennas, yacht docks, garden tools and accessories.
2. Current status of domestic pultruded fiberglass products
China's fiberglass pultrusion industry has developed rapidly in recent years. Due to low investment and quick startup, it has shown a phenomenon of blooming everywhere, but the scale is not very large, leading to many manufacturers repeating at a low level. Currently, China's fiberglass pultrusion factories can be roughly divided into: 1. Original factories that have imported equipment and technology.22. Entrepreneurs who have gained pultrusion experience and sales channels from original factories and started their own businesses.33. Self-manufacturers who have transitioned from users to manufacturers.44. Entrepreneurs who start purchasing equipment and technology due to having orders. This situation has led most pultrusion manufacturers to focus on one market, one product, and one process, or even just one user. They keep the technology and users they have mastered a secret, resulting in insufficient personnel or time to experiment with the development of new materials, let alone market development.
CurrentlyChina's fiberglasspultruded products have formed manyseries, such as channel, angle, I-beam, square tube, rectangular tube, round tube, round rod, etc., but the specifications and dimensions of each manufacturer, especially the mechanical performance indicators, vary greatly, leading to inconsistent product quality.This inconsistency causes inconvenience for users in design and use. It also makes it easier for inferior products to mix into the market, resulting in quality accidents and adverse effects.Secondlydue to insufficient development efforts in the domestic market, many products are sold abroad, and most ordersarein the hands of foreign agents, forming a cake that everyone fights over, inevitablyleading toprice wars among themselves, which pleases the agents.This situation.自家打起价格战，乐坏了代理商的情况。
