High-speed guardrail screws

High-speed guardrail screw is a kind of screw used to fix the highway guardrail. It is mainly composed of two parts, screw and nut, the length and diameter of the screw according to the required fastening force and the thickness of the guardrail material. Usually made of stainless steel material, with corrosion resistance, high temperature resistance, wear resistance, tensile resistance and other characteristics.

The material of high speed guardrail screw is made of stainless steel, which has good corrosion resistance. As installed on the highway, the screw needs to withstand long-term ultraviolet radiation and temperature changes in different seasons, so it needs to have a certain degree of weather resistance. At the same time, frequent vehicle traffic on the highway, screws need to have sufficient wear resistance to ensure long-term use will not occur loose or even fall off.

The installation of high-speed guardrail screws need to pay attention to the following points:

1. Select the appropriate specifications of the screw: according to the thickness of the guardrail and fixed force requirements, select the appropriate length and diameter of the screw.

2. Pre-punched: in the guardrail needs to be fixed position, first use the drill to punch a good screw hole.

3. Fixed force mastery: in the fixed guardrail, need to master the tightening force of the screws, should not be too tight or too loose.

4. The choice of installation: installation of high-speed guardrail screws can be used manually or mechanical equipment fixed.

High-speed guardrail screw installation for the highway traffic safety has a vital role. The use of high-quality screws for fixed, can ensure that the guardrail will not be because of the screw loose and fall off the accident, to ensure the safe passage of the highway. At the same time, regularly check the tightening of the screws to ensure that the guardrail is always in a stable state, is also one of the important measures to protect the highway traffic safety.
