SS 304 & SS 316 Puddle Flange Price List (2025 Updated)

 

Introduction

Puddle flanges are vital components in plumbing and waterproofing systems, especially where pipes penetrate concrete structures. Stainless Steel (SS) puddle flanges, particularly SS 304 and SS 316 grades, are highly preferred for their superior corrosion resistance and durability. Whether you're working on industrial, commercial, or residential projects, understanding the price differences and applications of these two grades is crucial for making the right purchase.

What is a Puddle Flange?

A puddle flange is a flange welded around a pipe where it passes through concrete walls or slabs. It serves as a waterproofing barrier by allowing waterproof membranes to “puddle” or collect around the flange, preventing water from seeping through pipe penetrations.
