steel highway guardrail for sale

steel highway guardrail for sale introduce

steel highway guardrail for sale competition is very fierce, which requires every manufacturer to improve the quality and improve their own service.

All parts of corrugated guardrail board are generally treated with hot-dip galvanizing for metal surface treatment. In order to ensure its corrosion resistance, high-speed guardrail board needs to be tested from three aspects: zinc coating adhesion, zinc coating uniformity and zinc coating adhesion.

steel highway guardrail for sale so what's the test standard for them? Now let's explain steel highway guardrail for sale to you.According to the location, they can be divided into roadside guardrail and central divider guardrail.

The test piece shall be placed horizontally, the hammer head shall face the bench, the hammer handle shall be vertical to the base plane, and then steel highway guardrail for sale shall fall freely, strike five points in parallel at an interval of 4mm, and judge the adhesion by checking the surface state of zinc layer and whether there is zinc layer peeling and bulging.

The properties of steel mainly refer to mechanical properties, which can be divided into strength properties, plasticity and impact toughness. Strength performance refers to the resistance of steel to plastic deformation and failure.

Application of highway guardrail

steel highway guardrail for sale including elastic limit, yield limit, strength limit, fatigue limit and hardness. Plasticity refers to the plastic deformation capacity of steel, including elongation. Area reduction and cold bending. Impact toughness indicates the resistance of steel to impact load.

As the content of various components in the material affects the mechanical properties of steel, the performance test of steel plate raw materials includes chemical analysis, tensile test and bending test.The zinc used for dip galvanizing shall be No.0 or No.1 zinc specified in gb470.

The test of zinc adhesion can be conducted by antimony trichloride method or coating thickness gauge.Component name average zinc adhesion (g / m2), zinc adhesion (g / m2), average zinc layer thickness (mm), zinc layer thickness (mm)。Guardrail plate, end and column 600425 ≥ 85 ≥ 61。Fastener, anti blocking block and towing frame 350275 ≥ 50 ≥ 39.

steel highway guardrail for sale analysis

Basic principle of antimony trichloride method: since zinc can be completely dissolved in concentrated hydrochloric acid solution of antimony trichloride, the zinc adhesion per unit area of high-speed guardrail can be calculated by weighing twice before and after dissolution.

The corrugated guardrail board can be easily inserted into the pre-set plugging hole at the opening by using the plug-in steel column, which plays the role of isolation and protection.

steel highway guardrail for sale the rusty galvanized guardrail plate shall be cleaned in time and recovered by category. As guardrail is a common high-speed fence construction material, steel highway guardrail for sale still has a larger scope of application after professional recycling and degradation treatment.

In the process of producing galvanized guardrail plate, the surface of guardrail will be treated, including hot-dip galvanizing, spray molding, hot-dip galvanizing spray molding and other methods, the main role is anti-corrosion and anti-oxidation.

Make steel highway guardrail for sale more conducive to improve the service life.Regular maintenance is an indispensable link. Regular maintenance is adopted to separate the long-distance highway guardrail products.

Road maintenance and construction personnel should pay more attention to whether the guardrails on both sides are damaged, welded or severely corroded in the process of regular detection of the highway.

Guardrail end terminals

steel highway guardrail for sale should inform the high-speed road management center in time to send professionals. The maintenance personnel shall carry out site cleaning, replacement or other maintenance work.At the same time, steel highway guardrail for salecorresponds to the guardrail belt on the outside of the road, which is neat, uniform and beautiful.
