Material properties:

According to the specific mechanical, electrical, anti-corrosion, flame retardancy and other requirements of the user for the profile, the designer must make a reasonable material structure design and select the appropriate combination of raw materials, including resin, reinforced fiber and other materials. Please refer to the physical properties table of pultruded FRP

Material advantages:

High strength, light weight, corrosion resistance, insulation, flame retardant. No electromagnetism. Low thermal expansion coefficient, good low temperature performance, aging resistance, strong designability, beautiful appearance, etc.

FRP pultrusion profiles are square, with uniform wall thickness on each side, smooth and glossy surface. In particular, observe the distribution of the internal felt, and there is no phenomenon that the felt cannot be covered, and there is no accumulation of excess resin. The feel on the surface is even, there is no yarn leakage, and the felt layer is evenly distributed. Therefore, the quotation of FRP pultrusion profile is also different.

The composite marker post is made of high-strength glass fiber and unsaturated resin by pultrusion, which has the advantages of beautiful appearance, tear heart, easy construction, high temperature resistance, corrosion resistance, oxidation resistance, high strength, non fragile and non recyclable.

The traditional marker post is cast with cement as a whole, with unclear handwriting and weak warning. The surface of the cement column is easy to fade, there is no guide and learning head, and the construction is inconvenient and difficult to maintain. This is a generation of marker post.

While the second-generation plastic steel (PVC) marker post has the advantages of light proportion, easy construction and beautiful appearance, it is easy to age, has no real temperature, and can be recycled (easy to be stolen).

Therefore, composite material marker post is a good substitute for cement and PVC marker post. It has been widely used in natural gas, oil, electricity, transportation, communications, water supply, and other pipeline lines.

I hope I can help you with the explanation of the production process and raw materials of buried marker posts. If you have any purchase needs, please pay attention to our website http://webtest2.daoshangbao.cn Contact me.
