The characteristics and development trend of guardrail

There are generally many types of guardrails. At present, the main paint-based iron railings or iron flower railings on the market, but they are generally unevenly painted, easy to rust, and iron flower fences have the disadvantages of being easy to break and weakly welded. . For this reason, we believe that plastic-dipped iron fences, wire mesh plastic-dipped fences or plastic steel fences are the future development trend, and people are paying more and more attention now. According to our recent 10 years in highways or railways and in recent years in municipal From the use of road isolation dipping fences, we believe that the price of dipping fences is very high, and it has the advantages of beautiful appearance, saturated color, anti-aging, convenient installation, firmness, easy cleaning, and no maintenance.

1. Wrought iron fence:
The iron dipping fence is a new type of durable and anticorrosive environmental protection fence. The steel components, wrought iron railings, road isolation fences, balcony fences, shelf air-conditioning racks and other series of products after dipping treatment adopt high-tech anti-corrosion treatment technology, and dip a layer of thermal engineering plastic with strong adhesion on the surface of the steel body. Layer, the steel body is completely isolated from air, moisture and acid-base substances, achieving the effects of wear resistance, strong UV resistance, corrosion resistance and rust resistance. Its appearance is full and lustrous, the colors are diverse, the service life is long without painting and maintenance, and it is easy to clean. It also has the advantages of simple, beautiful, firm and diverse varieties of traditional iron railings. The production of this product is factory-oriented and intensive, which greatly guarantees the stability of product quality, energy saving and consumption reduction. The product only needs to be assembled on site simply and without using the site and construction period of the construction unit.

2. Wire mesh dipping fence
The fence adopts high-quality low-carbon cold drawn steel wire, cold-formed steel, straight seam steel pipe, high-adhesion PE or PVC thermal engineering powder, proprietary adhesive and other raw materials. It adopts professional automated assembly line operation, and performs welding and forming before galvanizing. Then use high-adhesion PE dipping or polyester electrostatic spraying, single-layer dipping and other anti-corrosion treatment processes, which are durable, non-corrosive, strong UV resistance, no pollution, no deformation, beautiful appearance, bright color, smooth and delicate specialty. And the cost is much cheaper than the fence of the same purpose, and it does not take up more space.

Three, steel isolation fence
The new type of plastic steel (PVC) guardrail (polyvinyl chloride) is made by the process of extruding and coating vinyl plastic and plastic profile on the surface of the metal profile. The specifications are diverse, the colors are rich, and the ornamentation is strong. A large number of model products are available for users to choose and customize.
Secondly, it has high strength and toughness. PVC guardrails can complete a 100 kg weight test, and their strength and toughness are far superior to ordinary wooden guardrails. The guardrail can resist 7-8 strong winds through reasonable installation of columns and horizontal bars.
Finally, the service life is relatively long. The service life of PVC guardrail is 15 years, and generally can reach about 20 years. There is no need for rust removal, paint, or special maintenance. When it gets dirty, it can be refreshed easily with water and detergent. The viewing effect can be guaranteed to be consistent.
The production of this product can all be factoryized and intensive, which greatly guarantees the stability of product quality, energy saving and consumption reduction. The products only need to be assembled on site simply and without using the site and construction period of the construction unit.
