Generally speaking, the service life of highway guardrail network is 5-10 years. Guardrail net is a gate made of metal mesh welded to the supporting structure to prevent people and animals from entering the guarded area. Guardrails and barriers should be installed on both sides of expressways and first-class passenger roads. To avoid illegal encroachment of highway land. One of the anti-corrosion methods for guardrail nets used by guardrail manufacturers: zinc steel guardrail dipping is a plastic coating process, which is to coat plastic on a substrate (usually metal) by powder dipping.
It originated from the vulcanized bed method. The so-called vulcanized bed was first used in the contact decomposition of petroleum on the Winkler gas generator, and then the solid-gas two-phase contact process was developed, and was later gradually used in metal coating. Plastic dipping is to heat the metal and spray plastic powder evenly on the metal to form a layer of plastic film, or heat the plastic dipping liquid and put it into the metal parts to cool them and then the plastic is coated on the metal surface. This process is widely used because it does not require molds, has low processing costs, is simple to form, and can process various shapes.
We use heavy-duty anti-corrosion coatings for guardrails. Heavy-duty anti-corrosion coatings refer to those that can be used in relatively harsh corrosive environments compared to conventional anti-corrosion coatings, and have a longer protection period than conventional anti-corrosion coatings for guardrails. Anti-corrosion coating. Regarding the use of heavy-duty anti-corrosion coatings for guardrail nets: How can guardrail nets be used under harsh conditions and have long-term anti-corrosion life?
Heavy-duty anti-corrosion coatings can generally be used for more than 10 or 15 years in chemical atmospheres and marine environments. They can also be used for more than 5 years even in acid, alkali, salt and solvent media and under certain temperature conditions. Thick film is an important sign of heavy-duty anti-corrosion coatings. The dry film thickness of general anti-corrosion coatings is about 100 μm or 150 μm, while the dry film thickness of heavy-duty anti-corrosion coatings is 200 μm or more than 300 μm, and there are also 500 μm ~ 1000 μm, or even as high as 2000 μm. The columns of guardrail nets are made of concrete cast parts.
The project cost is low, the strength is high, the overall stability is good, the colorful plastic layer has good anti-corrosion and decoration effects, and the guardrail fence is overall harmonious and beautiful. Concrete columns can be made by local surplus labor and simple molds. You only need to purchase structural mesh sheets from our factory. The guardrail mesh can significantly reduce the project cost and is an ideal choice for your fence construction. Guardrail net has the characteristics of durability, beauty, broad vision and excellent protective function.
