Assembling galvanized guardrail fitting bolts

After hot-dip galvanizing, high-strength bolts for high-speed guardrails should be coated with butter on the surface of high-strength bolt connectors, and phosphating and lubricating. Packaging should be sealed at the factory to prevent rust or stains during shipping and storage. After hot-dip galvanizing of corrugated cardboard, plastic coating should be used. The polypropylene fabric should be used at the factory to prevent scratching and discoloration on the surface of galvanized steel.

High-speed guardrail bolts have very important significance under high strength, and can be consistent with the use of standard, high-speed guardrail screws in different jobs. It includes hexagon head screws, guardrail anti-theft screws, hot-dip galvanized bolts, etc., which is very convenient for use.

It has strong corrosion resistance and oxidation resistance. Because of its strong adaptability, it can better promote future applications. With the continuous development of the electronics industry, we continue to make progress.

In addition to electronic equipment, high-speed guardrail screws will also be used in digital products and the like. The shape of the screw will be different, so it will be very convenient and convenient to use. Due to the small shape standard, the use of lunch is easy for some workers.
