Traffic guardrail H post

Steel H post has the following advantages:

1. High strength: The section shape of H post is reasonable, able to withstand complex mechanical forces, with high strength.

2. Good stability: The upper and lower flange pressure bar and the groove of the middle waist bar of the H-section steel column can make the stability of the structure better, and enhance the bending, torsion and extrusion resistance.

3. Strong anti-corrosion: After hot dip galvanizing, H-beam post has good anti-corrosion and anti-oxidation effect to protect the long-term service life of steel structure.

4. Convenient construction: The section shape of H-beam post is regular, easy to cut, drill and weld, convenient for site construction.

5. Beautiful appearance: The shape of H beam column is beautiful and generous, in line with the aesthetic requirements of modern architecture.

In short, as a support material for guardrail and other building structures, H beam steel column has the advantages of high strength, strong anti-corrosion, good stability, convenient construction and so on.

The general length of the ASTM Steel H post is 1830mm, 1500mm, and 1750mm. Holes are drilled on both sides of the H post

Specification of ASTM Steel H Post:

H column drilling refers to the perforation process on the H-shaped steel column for easy installation and fixing. The following are the general steps for H column drilling:

1. Preparations: Confirm the size, model, and drilling position of the H-shaped steel column, and prepare required drilling tools and equipment.

2. Positioning and marking: According to the design requirements, position and mark the H-shaped steel column to determine the hole position. You can usually use a ruler, pencil, or plaster line to mark.

3. Drilling operation: Use a drilling machine or electric drill and other tools to drill holes according to the marked positions. According to the actual needs, select the appropriate drill bit to ensure the quality and efficiency of drilling.

4. Cleaning and trimming: After drilling, use a wire brush or cleaning cloth to clean the debris and metal shavings at the hole. For holes with uneven edges or burrs, you can use a file or sandpaper to trim them.

5. Inspection and quality control: Check the hole aperture, depth and position to ensure consistency with the design requirements. If the problem is found, it should be corrected or repunched in time.

6. Finish the work: After the drilling is completed, anti-rust treatment and painting can be carried out to extend the service life and beauty of the H-shaped steel column.

It should be noted that the operation of H column drilling needs to pay attention to safety issues, wear personal protective equipment, and use tools and equipment reasonably. Sometimes, the drilling process may produce large noise and dust, and corresponding measures should be taken for protection and treatment. In addition, the design and requirements should be carefully checked before drilling to ensure that the drilling position, quantity and specifications meet the requirements.
