steel roadside guardrails for sale introduce

steel roadside guardrails for sale reduce the losses caused by traffic accidents, the improvement of guardrails on both sides of the road has been strengthened. In order to prevent runaway cars from running out of the road and causing heavy losses, guardrails play an important role.

Galvanizing surface roughness: when the formation of iron zinc alloy is too much or the distribution is uneven,steel roadside guardrails for sale will cause surface roughness. And there may be a little white rust on the surface, and the guardrail board with white rust will make people feel serious corrosion.

This white powder is not rust of zinc layer, it only needs to be wiped and treated with weak acid. This kind of white rust is due to the high stability, which makes the formation of iron zinc alloy core element and the long time of galvanizing.

steel roadside guardrails for sale increases the diffusion reaction of iron and zinc. When galvanizing the guardrail plate, if the residual moisture contains chloride, sulfide in the industrial environment or the zinc content in galvanizing is too high.

steel roadside guardrails for sale is necessary to replace the galvanizing solution or reduce the temperature, and salvage the zinc slag, so as to steel roadside guardrails for sale prevents the zinc particles from being too dense. However, due to the hot-dip galvanizing process and cost control and other reasons.

Application of highway guardrail

steel roadside guardrails for sale is inevitable to have a small amount of zinc particles. Agglomeration, zinc nodules and flow marks: excessive pickling results in uneven distribution of elements in the steel matrix, resulting in rough surface due to different dissolution speed or micro battery effect during pickling.

The above is the roughness of zinc coating caused by the process, which can be improved by adjusting the process. Due to the rough surface of the selected steel, corrosion or obvious rolling stripe, the surface will still have rough phenomenon after galvanizing. Or affected by steel composition.

when carbon element is more than 0.2%, phosphorus is more than 0.5%, manganese is more than 13%, the galvanized layer formed is different from the normal galvanized layer. In these cases, the galvanizing process can only achieve limited control.

steel roadside guardrails for sale in the process of transportation and loading and unloading, the guardrail material inevitably produces scratches. From the characteristics of hot galvanizing.

steel roadside guardrails for sale description

we can know that zinc and The color difference of iron is obvious, but the anode protection characteristic of zinc layer can protect the surface from slight scratch. For scratches.

steel roadside guardrails for sale zinc rich paint can be used.The bubble of zinc coating is caused by excessive pickling of steel roadside guardrails for sale before plating or insufficient inhibitor added to the acid solution, resulting in more hydrogen adsorbed on the surface of steel parts during pickling.

without drying water and degassing before entering into the zinc pot, and the hydrogen adsorbed by steel is discharged during the solidification of the zinc plating solution to form bubbles. A large number of bubbles exist, which steel roadside guardrails for sale makes the galvanized layer loose and not dense. Under the high temperature, rain and humidity environment.

the galvanized layer is oxidized into white rust, which produces zinc oxide, zinc hydroxide, zinc carbonate and other zinc corrosion products. That is to say, the white ash on the surface of highway guardrail plate is seen on the road.

If the zinc layer is oxidized to lime and the zinc layer is thinned, the copper sulfate solution will not pass the immersion test. Article 5.1 of American Standard Specification for hot dip galvanizing of steel parts 6ma153 (reapproved in 1987) clearly states: "galvanized parts shall be free from uncoated parts, bubbles, flux deposition, black spots.

traffic guard rails

steel roadside guardrails for sale solvent inclusions and all kinds of projections that may hinder the use of galvanized parts in the future, or other defects incompatible with good galvanizing operation.
