How to Check if WF Iron is Original or Reconditioned

In the construction world, selecting genuine, high-quality Wide Flange (WF) steel profiles is crucial to ensure the strength and safety of building structures. However, there are many reconditioned WF steel products on the market that appear similar to the original product. If not carefully considered, the wrong choice can have significant consequences, both technically and financially.

What is Reconditioned WF Steel?
Reconditioned WF steel is steel scrapped from projects that has been re-polished, painted, or even re-ground to look like new. Although cheaper, the quality and strength are certainly not as good as the original factory-made product.

Why Be Careful?
Using reconditioned WF steel without understanding its history and strength can lead to:

• Structural failure
• Premature corrosion
• Sizing errors
• Failure to comply with SNI or project standards

How to Check Genuine or Reconditioned WF Steel
Here are some steps to distinguish between genuine and reconditioned WF steel:

1. Look at the Steel Surface

• Genuine: The surface is flat, smooth, and precise. It is usually coated with mill scale (a natural black coating from production).
• Reconditioned: The surface is often uneven, wavy, or has weld and grinding marks. Paint can mask defects or rust.

2. Check Factory Markings / Production Marks

• Authentic: There is an embossment or stamp from the factory, such as the brand, size, and heat number.
• Reconditioned: Usually no factory markings. If there are, they may be re-screened or not meet official manufacturer standards.

3. Measure Dimensions and Weight

• Authentic: Dimensions and weight are consistent with SNI or JIS standards.
• Reconditioned: Dimensions may have shrunk due to sanding or cutting processes. The weight often does not match the steel table.

4. Ask for a Mill Test Certificate (MTC).

• Authentic: Accompanied by an MTC, which lists the results of chemical and mechanical tests on the steel.
• Reconditioned: No supporting documentation.

5. Examine the Ends and Joints

• Authentic: The ends are precise and there are no visible rough cuts.
• Reconditioned: Flame cuts, welds, or even welded joints between scrap metal pieces may be visible.

Additional Tips:

• Buy from a trusted distributor that guarantees quality and authenticity.
• Avoid purchasing WF steel from unknown sources simply because you're tempted by a low price.

Conclusion
Checking the authenticity of WF steel isn't just about appearance, but also about the safety and durability of the building structure. Refurbished products may look similar, but they differ significantly in performance. If in doubt, always consult a professional supplier.
