Stainless Steel Fabrication Services for Industrial Projects
Basic Description
Sagiant Piping Industries provides stainless steel fabrication in 304, 304L, 316, 316L and 430 (ASTM A240) — hygienic tables, hoods, tanks, enclosures, railings and architectural features, TIG/MIG welded, passivated and finished to brushed or mirror standard for food, pharma, chemical and architectural use.

Frequently Asked Questions
304 vs 316 — which do I need?
304 for general/food use; 316 where chlorides, acids, marine or pharma conditions demand extra resistance.
Do you passivate after welding?
Yes — pickling and passivation restore the corrosion-resistant layer at welds.
Can you achieve hygienic / sanitary welds?
Yes — crevice-free, ground-and-polished welds to food/pharma standards.
Which finishes do you offer?
No.4 brushed, No.8 mirror, bead-blast and electropolish.
