Frequently Asked Questions

What is the difference between 304 and 316 stainless steel bars?

While both are austenitic, 316 contains molybdenum, which significantly increases corrosion resistance, particularly against chlorides and marine environments, compared to 304.

Do your products comply with international standards?

Yes, all our stainless steel bars meet the strict requirements of ASTM A276 and ASME SA479, ensuring consistent quality and structural integrity.

What surface finishes can I choose from?

We offer a variety of finishes including Pickled, Black, Bright (Cold Drawn), Polished, and Sand Blasting to meet your specific application needs.

Can you provide custom lengths for the bars?

Absolutely. While standard lengths are 5.8m or 6m, we can cut the bars to specific lengths as required by your project.

What is the typical lead time for an order?

Lead time depends on the specific grade and quantity ordered. Standard sizes are often in stock, while custom requirements are processed according to our current production schedule.

What shapes of stainless steel bars are available?

We provide a full range of shapes including Round, Square, Hexagonal, Flat, and Angle bars in various dimensions.
