At Allora USA, we take pride in offering true 304 stainless steel sinks that deliver lasting performance, superior corrosion resistance, and timeless style. Unfortunately, not every brand can say the same.
In today’s market, many sinks are advertised as “304 stainless steel” or “heavy gauge,” but many are built with lower-grade alloys and thinner steel that rust, discolor, and wear prematurely. The result is rust, discoloration, and premature wear, especially in high-moisture environments like kitchens and bathrooms.
Here’s what you should know before selecting your next stainless steel sink.
Why True 304 Stainless Steel Matters
304 stainless steel is the gold standard for food-grade and high-moisture applications. It contains roughly 18–20% chromium and 8–10.5% nickel, which gives it superior resistance to corrosion and rust.
By comparison, 202 stainless steel replaces much of the nickel with manganese, lowering production costs but also reducing durability. While the two materials may look similar, 202-grade steel rusts and stains much more easily, particularly in humid or coastal environments.

That is why Allora USA uses only certified 304 stainless steel across our sink collections. We never compromise on material integrity — every sink we make meets the highest standards of performance, finish, and longevity.
The Problem: False “304” Claims and Misleading Gauges
Some manufacturers advertise their sinks as “304 stainless steel” even when they are not. Without proper documentation, you could be purchasing a sink made from 202 or even lower-grade steel.
Gauge claims are also often misleading. Some companies promote their products as “16-gauge stainless steel,” but in reality, only part of the sink, such as the rim or certain sections, is made from 16-gauge steel, while the rest is formed from thinner 18- or even 20-gauge material. This inconsistency results in uneven durability, greater vibration, and thinner bowl walls that dent or fatigue over time.

At Allora USA, we take gauge integrity seriously. Every sink we produce is made from consistent, true 16- or 18-gauge 304 stainless steel throughout, not just in select portions. Our materials and manufacturing processes are verified through rigorous internal testing and quality control to ensure uniform strength, exceptional sound absorption, and long-term performance that endures year after year.
Beyond a Single Brand: The Widespread Issue of Mislabeled Sinks
This problem goes far beyond any single brand or model. Across the industry, mislabeled stainless steel sinks are becoming increasingly common, especially on online marketplaces and among unbranded imports.
Here’s what to watch for:
- Generic or unbranded sinks often claim to be 304-grade but are made of inferior, cheaper materials.
- Online marketplaces may list products with inaccurate or misleading descriptions, making it difficult to verify what you are actually buying.
- Lower-grade substitutes, such as 201 or 430 stainless steel, are sometimes used instead of 304. These alloys have lower nickel content, are magnetic, and are far more susceptible to corrosion and rust.

How to Avoid Being Fooled
To ensure you are getting what you pay for, here are a few simple ways to protect yourself and your projects:
|
|
Buy from reputable brands:Established manufacturers like Allora USA are transparent about material specifications, provide detailed documentation, and back their products with customer support. |
![]() |
Check for certifications:Reputable brands list material grades clearly on product labels or packaging and can provide Certificates of Origin or Certificates of Quality (CO/CQ) upon request. |
![]() |
Perform a magnet test:Genuine 304 stainless steel is non-magnetic or only weakly magnetic. If a magnet sticks strongly to the main surface of the sink, it is likely made from an inferior grade such as 201 or 430. |
![]() |
Use a testing solution:Stainless steel testing solutions are available online. Apply a drop to a discreet area of the sink. If the solution changes color (for example, turns red), it is a sign the material is not true 304 stainless steel. |
Taking these precautions ensures your projects use materials that truly stand the test of time.
