A 4×8 stainless steel sheet is a flat-rolled stainless steel product with a nominal width of 4 feet and length of 8 feet.

The dimensions correspond to:

Width: 48 inches = 1219.2 mm

Length: 96 inches = 2438.4 mm

Surface Area: 32 square feet = approximately 2.973 m²

In commercial specifications, this size is frequently described as 1219 × 2438 mm.

The 4×8 format is widely used by sheet metal manufacturers because it provides a standardized starting size for cutting, bending, punching, welding and other fabrication processes.

Unlike a stainless steel grade designation, 4×8 describes the sheet dimensions rather than its chemical composition or mechanical properties.

For example, a 4×8 stainless steel sheet can be manufactured from Grade 304, 316L or 430, with different thicknesses and surface finishes.

The correct material combination depends on the intended operating environment, corrosion exposure, fabrication requirements, appearance and purchasing budget.

Important: Not every grade, thickness and surface finish is available in every combination. Decorative finishes generally have more limited thickness ranges than mill-finish products.

Final dimensions, tolerances and delivery conditions should be confirmed in the purchase order.

Selecting the correct sheet size helps reduce material waste and improve fabrication efficiency.

Metric dimensions for imperial sheet sizes are rounded in the table.

4×8 vs. 4×10 Stainless Steel Sheets

A 4×8 sheet provides 32 square feet of material, while a 4×10 sheet provides 40 square feet.

Both have the same nominal width, but the 4×10 sheet is 25% longer and contains 25% more surface area.

A larger sheet may reduce the number of joints in some fabricated products, while a 4×8 sheet may offer better material utilization for smaller parts.

Buyers should evaluate the nesting layout, cutting method, handling equipment and finished part dimensions before selecting a sheet size.

We supply 4×8 stainless steel sheets in different grades to meet industrial, commercial and architectural requirements.

Grade equivalents are provided for material identification. Actual interchangeability must be checked against the applicable product standard and purchase requirements.

304 Stainless Steel 4×8 Sheets

Grade 304 is a common selection for general sheet metal fabrication.

It combines useful corrosion resistance, ductility, weldability and availability.

Typical applications include:

Commercial kitchen equipment

Food-processing machinery

Stainless steel cabinets

Architectural panels

Industrial enclosures

General fabricated components

Grade 304 is commonly selected for indoor and moderate outdoor environments where aggressive chloride exposure is not expected.

316L Stainless Steel 4×8 Sheets

Grade 316L contains molybdenum, which improves resistance to localized corrosion in many chloride-containing environments compared with Grade 304.

Its low carbon content also reduces the risk of sensitization-related intergranular corrosion during suitable welding operations.

Typical applications include:

Chemical processing equipment

Coastal architectural components

Industrial tanks and enclosures

Food-processing equipment

Pharmaceutical equipment components

Equipment exposed to selected corrosive environments

316L is not immune to chloride pitting, crevice corrosion or stress corrosion cracking.

Material suitability depends on chloride concentration, temperature, pH, cleaning chemicals, fabrication condition and service environment.

430 Stainless Steel 4×8 Sheets

Grade 430 is a ferritic stainless steel containing approximately 16–18% chromium.

It is magnetic and generally has lower nickel-related raw material cost exposure than common austenitic grades.

Typical applications include:

Appliance panels

Decorative trim

Commercial kitchen components

Interior architectural panels

Equipment covers

Grade 430 is best selected where its corrosion resistance and fabrication characteristics meet the actual operating conditions.

The following table summarizes selected alloying elements commonly used to distinguish these stainless steel grades.

Values are for preliminary material comparison. Complete chemical acceptance limits, including manganese, silicon, phosphorus, sulfur and nitrogen where applicable, must be checked against the specified edition of ASTM A240/A240M or the agreed material standard.

Chemical composition should be verified against the applicable mill test certificate.

Mechanical properties vary with stainless steel grade, thickness, manufacturing condition and the applicable material specification.

The following values are commonly referenced minimum requirements for selected annealed ASTM A240 stainless steel sheet grades.

Technical Note: These are reference values for commonly specified annealed products, not guaranteed values for every thickness or condition. Certain thin-gauge products have different elongation requirements. Cold-worked materials may have substantially different properties.

For structural or pressure-containing components, the final material specification, design code and certified mechanical properties must be checked by the responsible engineer.

The correct sheet thickness depends on stiffness requirements, forming operations, load conditions, surface finish and fabrication method.

Applications are illustrative only. Thickness selection must be based on design requirements rather than the examples above.

Stainless Steel Sheet Gauge vs. Thickness

In North American markets, stainless steel sheets may also be ordered by gauge.

Common commercial stainless steel sheet gauges include 20 gauge, 18 gauge, 16 gauge and 14 gauge.

However, gauge thickness conventions can differ between stainless steel, carbon steel and aluminum.

For international purchasing, we recommend specifying the exact thickness in millimeters or inches instead of using gauge numbers alone.

Sheet weight is an important consideration for international shipping, material handling, fabrication and purchasing cost calculations.

The following table gives the approximate theoretical weight of one 4×8 ft Grade 304 stainless steel sheet.

Sheet Size: 1219.2 × 2438.4 mm
Material: 304 Stainless Steel
Density Used: 7.93 g/cm³

Stainless Steel Sheet Weight Formula

For sheet dimensions in millimeters:

Weight (kg) = Thickness (mm) × Width (mm) × Length (mm) × Density (g/cm³) ÷ 1,000,000

For example, a 2 mm thick Grade 304 stainless steel sheet measuring 1219.2 × 2438.4 mm has an approximate theoretical weight of:

2 × 1219.2 × 2438.4 × 7.93 ÷ 1,000,000

= 47.15 kg per sheet

Actual weight may vary according to manufacturing tolerances, material density and measured dimensions.

316L and 430 stainless steel sheets have different densities, so their theoretical weights should be calculated separately.

For commercial quotations, buyers should confirm whether pricing is based on theoretical weight, actual weight or price per sheet.

Different surface finishes provide different appearances, processing characteristics and maintenance requirements.

2B Finish – Cold Rolled Stainless Steel Sheet

2B is a common cold-rolled mill finish with a relatively smooth, moderately reflective surface.

It is frequently selected for industrial fabrication where decorative polishing is not required.

Applications: Equipment panels, cabinets, fabricated components and general industrial sheet metal.

BA Finish – Bright Annealed Stainless Steel Sheet

BA stainless steel has a bright surface produced through controlled-atmosphere annealing.

It is commonly used for appliances, decorative components and products requiring a relatively bright mill surface.

Applications: Household appliances, decorative panels and precision fabricated components.

No.4 Brushed Stainless Steel Sheet

No.4 is a mechanically polished finish with a directional grain pattern.

It offers a decorative satin appearance suitable for frequently handled commercial surfaces.

Applications: Commercial kitchens, elevator interiors, wall panels and equipment covers.

Hairline Stainless Steel Sheet

Hairline stainless steel features a fine, directional brushed pattern.

The visual appearance depends on the abrasive process, grain direction and agreed surface sample.

Applications: Architectural cladding, furniture panels, elevator interiors and decorative metalwork.

Mirror Polished Stainless Steel Sheet

Mirror stainless steel sheets are mechanically polished to achieve a highly reflective appearance.

Commercial descriptions may include No.8, 8K or mirror finish, but these terms do not automatically guarantee identical reflectivity or surface quality.

Applications: Decorative architecture, commercial interiors, elevator panels and feature walls.

No.1 Hot Rolled Stainless Steel

No.1 is a hot-rolled, annealed and descaled mill finish generally associated with thicker products.

It is selected primarily for industrial fabrication rather than highly decorative applications.

PVD Colored Stainless Steel Sheet

Decorative stainless steel sheets can be supplied with selected PVD colors, including:

Gold

Rose Gold

Champagne

Bronze

Black

Blue

Color consistency, abrasion resistance, coating adhesion and service suitability should be confirmed through approved samples and agreed inspection criteria.

Embossed & Etched Stainless Steel Sheet

Embossed sheets provide three-dimensional surface textures, while etched sheets use controlled surface removal to create decorative patterns.

These products are commonly selected for architectural and decorative applications.

The available pattern, material grade and sheet thickness should be confirmed before ordering.

Choosing the right grade is essential for controlling total material cost and achieving the required service performance.

Selection Recommendations

Choose 304 for general fabrication, indoor architecture, commercial kitchens and industrial equipment where exposure is moderate.

Choose 304L when a low-carbon grade is specified to reduce the risk of weld-related sensitization.

Choose 316L for selected coastal, chemical and chloride-exposed applications after evaluating the actual environment.

Choose 430 for suitable indoor decorative and appliance components where magnetic response and corrosion requirements are compatible.

For highly aggressive chloride environments, elevated temperatures or demanding chemical services, additional stainless steel grades may require evaluation.

Dongmeng supports stainless steel sheet procurement with processing options selected according to the product specification and project requirements.

Cut-to-Length Processing

Stainless steel coils can be processed into flat sheets according to specified dimensions.

The process may include leveling, length measurement, transverse cutting and sheet stacking.

Precision Cutting

Depending on thickness and project requirements, available cutting methods may include:

Shearing

Laser cutting

Plasma cutting

Waterjet cutting

Customized profile cutting

The selected process should account for edge quality, dimensional tolerance, heat-affected zones and downstream fabrication requirements.

Surface Processing

Available processing options include brushing, polishing, mirror finishing and selected decorative surface treatments.

For appearance-critical projects, buyers should approve a reference sample before bulk production.

Protective Film

Protective film may be applied to suitable surfaces to reduce handling damage during processing and transport.

Film type, adhesive strength, removal conditions and compatibility with laser cutting should be specified when necessary.

Fabrication Support

Additional operations, including bending, punching and welding, can be evaluated according to approved technical drawings and manufacturing capability.

Stainless steel sheets should be purchased according to an applicable product specification rather than by grade name alone.

Important Procurement Requirements

Before production or shipment, the purchase order should identify:

Applicable product standard and edition.

Stainless steel grade and UNS designation.

Required sheet thickness, width and length.

Applicable dimensional tolerance system.

Surface finish and visual acceptance requirements.

Edge preparation and protective film requirements.

Inspection and certification requirements.

Quantity, packaging and delivery terms.

ASTM, EN and JIS requirements should not be treated as automatically interchangeable.

The applicable standard must be specified in the purchase agreement.

Stainless steel derives its corrosion resistance from a chromium-rich passive surface film.

However, corrosion performance depends on more than the grade designation.

Relevant factors include chloride exposure, temperature, acidity, deposits, crevice geometry, welding condition and surface contamination.

Pitting and Crevice Corrosion

Chloride-containing environments may cause localized corrosion.

Grade 316L generally offers improved resistance compared with Grade 304 in many such environments, but neither grade should be described as completely resistant to seawater or concentrated chlorides.

Intergranular Corrosion

The low-carbon grades 304L and 316L help reduce sensitization-related corrosion risk after suitable welding operations.

However, the welding procedure, material condition and service environment must still be considered.

Bending and Forming

Austenitic stainless steels generally offer good formability, although springback and work hardening must be considered.

Bend radius and tooling requirements depend on material thickness, grade, orientation and delivery condition.

Welding

Welding procedures should be selected according to material grade, thickness, joint design and applicable fabrication code.

Appropriate filler metals, shielding gases, heat input and post-weld cleaning procedures are essential.

Stainless steel surfaces should be protected from contamination by carbon steel tools or particles during fabrication.

Commercial Kitchens & Food Equipment

304 and 316L stainless steel sheets are used in worktables, equipment covers, splashbacks, cabinets and selected food-processing components.

Surface finish and hygienic requirements should be specified according to the intended application.

Architectural Wall Cladding

Brushed, hairline, mirror and decorative stainless steel sheets are used for interior wall panels, elevator cabins, commercial buildings and architectural features.

Industrial Equipment Manufacturing

Stainless steel sheets are suitable for selected machine covers, equipment enclosures, fabricated housings and industrial assemblies.

Chemical Processing Equipment

316L and other corrosion-resistant grades may be specified for selected chemical-processing components where environmental compatibility has been established.

HVAC & Ventilation Equipment

Stainless steel sheets can be fabricated into equipment housings, ventilation components and selected ductwork where the grade meets design and corrosion requirements.
