Frequently Asked Questions

What's the difference between 304 and 316 stainless steel?

304 is a general-purpose grade with good corrosion resistance. 316 contains molybdenum, offering superior resistance to chlorides and marine environments, making it ideal for coastal or high-moisture areas.

Why use 2205 duplex stainless steel?

2205 offers higher strength and excellent resistance to stress corrosion cracking. It’s used in aggressive environments like chemical plants, offshore platforms, and high-salinity areas.

Do you offer custom finishes?

Yes. We provide #4 brushed, mirror polish, satin, and powder-coated finishes including black, gold, and bronze tones.

Can I get a sample?

Absolutely. We offer free samples for evaluation. Contact us to request your sample pack.
