Quality control point of galvanized wave guardrail
1. When we are in production and processing, we need to stake out first, make the template, and the template needs to be produced strictly according to the customer's needs.
2. The extrusion deformation process of the wave guardrail: the guardrail board is divided into two waves of guardrail board, three wave guardrail board and two waves Three-wave transition plates are processed by different production equipment.
3. The anticorrosive treatment effect of the corrugated guardrail galvanized must be good. The extruded corrugated guardrail needs to be galvanized in a high-temperature galvanizing furnace, and the temperature of the galvanizing furnace should not be too high or appropriate Too low, this requires strict control, otherwise it will directly affect the seeming effect.
4. The spray treatment of the wave guardrail: The spray treatment is also very strict. The spray guardrail board produced by some manufacturers is uneven, and the spray effect is not good. This is because the spraying equipment of the guardrail is not good, the spraying equipment is all assembly line operation, and the good spraying equipment is very uniform.
1. In terms of protection effect: the anti-collision levels of the cable guardrail and the guardrail board have their own protection levels: A, B, and S, but the protection effect of the cable guardrail is significantly better than the guardrail board. There are several cables for the cable guardrail. It is composed of steel wire rope, and its anti-collision and self-recovery ability is very strong. The guardrail is composed of corrugated steel plates, which can absorb the impact force of the car very well, but the self-recovery ability is poor, and the guardrail needs to be replaced after the impact.
2. Anti-corrosion: There are many anti-corrosion methods for cable guardrails and guardrails, but they are basically hot-dip galvanized. The anti-corrosion effect of hot-dip galvanized products is very excellent and can be used normally under outdoor conditions. Decades. Therefore, the anti-corrosion effects of the two road protection products are very good.
