S355 hollow section

What measures are taken to prevent corrosion during the export of S355 circular hollow section?

• The sections are thoroughly cleaned & dried to remove any contaminants that may promote corrosion.
• Protective coatings like oil based or rust inhibiting coatings are applied to the surfaces of the sections. This helps create a barrier against moisture and corrosive elements.
• The S355 circular hollow sections are securely packaged using appropriate materials providing resistance to moisture and environmental factors.
• Proper handling and storage practices are also followed to minimize the risk of corrosion during transportation and storage.

What are the common industry practices for ensuring weld quality in S355 box section?

• Careful selection of welding processes suitable for the S355 box section material. For example, MIG or TIG welding.
• Pre weld preparation is vital. It involves cleaning & removal of contaminants from the surfaces to be welded.
• Adequate welding parameters are used to achieve sound welds with proper fusion.
• Non-destructive testing methods help detect any defects in the welds

What are the common defects or anomalies that can be detected through visual inspection in S355 square hollow section?

• Surface irregularities, such as cracks, porosity or incomplete fusion, can have a significant impact on the structural integrity of the section. These imperfections may weaken the weld joint and compromise its overall strength.
• Additionally, discoloration, spatter or excessive weld reinforcement can serve as indicators of potential welding issues.
• Distortions, warping, or misalignment of the S355 square hollow section can be visually observed and indicate potential issues with the manufacturing or handling processes. These irregularities can affect the overall structural integrity and aesthetics of the section.
• Additionally, inconsistent dimensions, sharp edges or burrs may be identified, highlighting the need for further attention. It is to ensure proper dimensional accuracy and a smooth, safe surface finish.

How is the thickness of a S355 rectangular hollow section determined?

The thickness of an S355 rectangular hollow section is determined through measurements taken during the manufacturing process. The initial thickness of the steel plate used for forming the section is known. Post the hot or cold rolling process, the thickness is measured using calibrated gauges or ultrasound technology. The measured thickness is then compared to the required specifications to ensure compliance.

What surface treatment options are available to improve the appearance or corrosion resistance of S355 box section?

• The paint or powder coating forms a protective shield that helps to prevent moisture and environmental factors from directly contacting the metal surface. It reduces the risk of rust and deterioration.
• Galvanizing involves applying a layer of zinc to the S355 hollow section through a process called hot dip galvanization. This protective coating acts as a sacrificial barrier, as the zinc corrodes preferentially to the underlying steel.
• Metal plating like chrome/ nickel plating offers a decorative finish along with providing additional resistance to corrosion.

What are the pre-welding preparations required for S355 steel section welding?

• To ensure the optimal quality of S355 steel sections, it is crucial to conduct thorough cleaning of the welded surfaces to remove any dirt, oil, rust, or other contaminants. This cleaning process plays a vital role in promoting strong and reliable welds. Various methods can be employed to achieve this level of cleanliness, such as wire brushing, grinding or solvent cleaning.
• The edges of the sections may need to be prepared by chamfering or beveling. It helps to ensure proper penetration and fusion during welding.
• Proper fit up and alignment of the sections are crucial to achieving sound welds.
• Preheating may also be required for thicker sections or in cold weather conditions to prevent cracking.
