304 Stainless Steel Sheets Remain Industry Standard for Kitchen Industrial Use

October 25, 2026

A 1.5mm-thick 304-grade stainless steel sheet with a single-sided 240-grit brushed finish is specified as a standard material for food service, kitchen fit-outs and industrial fabrication, where corrosion resistance and formability are central requirements. The grade is positioned as a durable alternative to economy grades such as 430 and 431, which contain higher iron levels. Its low-iron composition and non-magnetic properties are cited as key differentiators for damp and steam-heavy environments.

Grade choice and corrosion performance

In catering facilities, kitchen construction and general manufacturing, corrosion resistance is a primary factor in material selection. The 304 grade is designed to remain stable in humid conditions, including exposure to steam and water vapor, and to resist rust formation more effectively than higher-iron economy alternatives.

Those characteristics make the alloy suitable for components that must retain both appearance and hygiene over time. The material's chemical composition underpins its performance in wet environments, where lower-grade steels may deteriorate.

Surface finish and specification

The sheet is treated with a 240-grit brushed finish on one side only. A peelable PVC film covers the polished surface to protect it during cutting, transport and installation. The reverse side is not specially finished and may carry minor scratches, which the specification describes as a normal part of the production process.

The following table summarizes the stated technical specifications.

Parameter Specification
Material grade 304 stainless steel
Sheet thickness 1.5mm
Surface finish 240-grit brushed, one side
Protection Single-sided PVC protective film
Magnetic properties Non-magnetic, low iron content
Applications across kitchen and industrial uses

With its mechanical properties and weather resistance, the 1.5mm 304 stainless steel sheet is used across several application categories. It can be bent and welded to meet complex fabrication requirements, supporting use in commercial and industrial projects.

  • Kitchen and catering: splashbacks, work surfaces and food-processing equipment.
  • Industrial manufacturing: ventilation ducts and bent or welded components.
  • Decorative and fit-out work: decorative panels, cooking appliances and worktables.

Typical uses include kitchen splashbacks, work surfaces, food-processing equipment, ventilation ducts, bent and welded components, decorative panels and cooking appliances. The material's formability allows fabricators to produce components with varied shapes while maintaining the required surface finish.

Frequently Asked Questions
Why is 304 stainless steel preferred in kitchen environments?
Kitchen environments often contain water vapor, steam and acidic or alkaline substances. Compared with lower-grade options such as 430, 304 stainless steel offers better corrosion resistance, is less prone to rust and can maintain a hygienic and presentable surface over time.
How should the unpolished side of the sheet be handled?
The sheet is polished on one side only and covered with a protective film. The unpolished side may have scratches from production, so it is recommended that this side be placed inward or in a non-visible area during installation to preserve the overall appearance.
Is 1.5mm 304 stainless steel magnetic?
Because 304 stainless steel has a low iron content, its physical properties are non-magnetic. For precision instrument applications with specific magnetic requirements, the suitability of this characteristic should be confirmed against the design requirements.
