2PCS 304 Stainless Steel Sheets, 8″ x 4″ x 0.04″ Inch

These two stainless steel plates measure 8″ by 4″ with a thin 0.04″ (1 mm) thickness. Made from 304 stainless steel, they resist rust and corrosion and feature flat edges with a coated surface. This size is ideal for crafts, small repairs, and kitchen DIY tasks where a compact, sturdy sheet is needed. Best for hobbyists or makers doing modular builds or small shims. A caution: not magnetized, which may limit magnetic mounting uses.
Why choose this product
- Compact, controllable size for precise projects
- 304 stainless steel offers corrosion resistance and durability
- Thin yet sturdy for easy cutting and shaping
2PACK 304 Stainless Steel Sheets, 4 x 8 x 1/8 Inch

Two 4″ by 8″ stainless steel sheets with a thickness of 1/8″ (approximately 3 mm) provide bulk for larger small-scale projects or multiple uses. The 304 stainless steel composition delivers rust resistance and reliable mechanical properties for crafts, electrical enclosures, or lightweight structural parts. This option is better for projects requiring a bit more material and rigidity, but it’s not magnetic.
Best use case
- Projects needing a sturdier plate than thin shims
- DIY kitchen or cabinetry components where a non-magnetic surface is acceptable
Uxney 1mm Stainless Steel Sheet 4×8 Inch

This sheet is a precise 4″ x 8″ plate, 1 mm thick, made from 430-grade magnetic stainless steel. The magnetizable surface makes it ideal for magnetic boards, tool organization, and magnetic crafts. It’s easy to cut and shape with common tools, supporting a range of DIY projects from jewelry components to small wall art. Best for projects that benefit from a magnetic surface. Caution: 430-grade steel is magnetic but may have different corrosion resistance than 304-grade stainless.
Who should consider this?
- People building magnetic displays or magnet-based storage
- DIYers needing a flexible, cut-friendly plate
2PACK 4 x 8 x 1/16 Inch 304 Stainless Steel Sheets

Two sheets measuring 4″ by 8″ with a thickness of 1/16″ (1.5 mm) provide a leaner, lighter option for shim work, small crafts, and fabrication projects where minimal material weight is beneficial. Made from 304 stainless steel, these sheets resist corrosion and offer stable dimensions for delicate builds. This choice suits budget-minded crafters who still need reliable steel.
Winfox 430 Stainless Steel Sheet Metal 4 x 8 Inch 0.5mm

This 4″ by 8″ sheet has a thickness of 0.5 mm and is made from 430-grade stainless steel. It is magnetic, which is useful for mounting displays or organizing metal tools. The polished finish and uniform thickness support crafts, small panels, and decorative applications. Best for magnet-friendly, budget-conscious projects. Limitation: thinner sheets may not be suitable for load-bearing parts or heavy structural uses.
Buying Guide: How to Pick the Right 4×8 Steel Sheet
What material matters most?
304 stainless steel offers excellent corrosion resistance and a non-magnetic to magnetic property depending on grade. 430-grade steel adds magnetism and good corrosion resistance but may be less durable in extreme environments. Choose based on exposure to moisture, chemicals, and magnetic needs.
How thick should the sheet be?
Thickness influences strength and ease of cutting. For delicate crafts, thinner sheets (0.04″ to 0.0625″) are easier to bend and shape. For small structural parts, a thicker sheet (0.125″ or more) provides rigidity. Consider your project’s bending radius and mounting requirements.
Magnetic vs non-magnetic considerations
Magnetic sheets are ideal for tool boards, magnetic displays, or cabinets. If you don’t need magnetic properties, non-magnetic options like many 304 stainless steel sheets still offer corrosion resistance and a strong working surface.
Finish and edge quality
Flat edges and coated surfaces reduce burrs and improve finish quality for crafts and wall art. A smooth surface enhances paint adhesion and reduces handling hazards during fabrication.
Recommended use scenarios
- Small crafts or prototypes: choose 0.04″–0.0625″ thickness in 304 stainless steel for ease of cutting and shaping.
- Magnetic organization or displays: select 430-grade stainless steel sheets with magnetic properties.
- Budget-friendly shim or spacer parts: 1/16″ to 1/8″ thick sheets in 304 stainless offer good value and versatility.
Maintenance and care
Clean steel sheets with a mild detergent and dry promptly to reduce water spots. Avoid harsh abrasives that can scratch coatings. For extended outdoor exposure, consider coatings or storage in a dry environment to minimize corrosion risk.
Frequently Asked Questions
- What does 4×8 mean for these steel sheets? It refers to the sheet dimensions in inches, 4 inches by 8 inches, providing a compact working area for small projects.
