Difference Between National Standard And Non-Standard Of Waveform Guardrail Difference Between National Standard And Non-Standard Of Waveform Guardrail

Wave guardrail is a semi-rigid traffic anti-collision facility. The raw material is Q235 low carbon steel. It has the advantages of simple production process, convenient installation and beautiful appearance. It is widely used on both sides of the road and in the middle of the road. The production standards are different, so there are also great differences in price. Next, let's talk about the difference between national standard and non-standard waveform guardrail.

It is mainly manifested in the following aspects:

1. Thickness:

There are two wave guardrails 4320 * 310 * 85 * 3 / 4mm and thrie wave beam guardrail 4320*506*85*3/4mm due to the different grade of the road. Non-standard guardrails are inferior on this basis. It can not be accurately visualized, so it needs calipers for actual measurement.


2. Surface treatment:

Firstly, the waveform guardrail should be complete, smooth, bright, with no zinc tumors, no leakage plating, and it is uniform in color. And the plate is not allowed to have torsion, edge wave and other deformation defects.

3. Thickness of zinc layer:

The thickness of zinc layer of waveform guardrail can be divided into three kinds: 600g full zinc layer, 300g semi-zinc layer and 100g zinc layer (galvanized white board). The average zinc coating of the national standard for galvanizing is 600g/with a thickness of 85um, and the average antiseptic coating of the national standard for spraying is 115 mg/. The zinc layer thickness and spray thickness are all non-standard products.

Having a comprehensive understanding of the non-standard national standard of the guardrail panel can help to avoid the mistakes in selecting products.
