What Is Sheet Metal Fabrication?

Sheet metal processing is a comprehensive cold processing technology for thin metal sheets (stainless steel sheets, aluminum sheets, etc., usually less than 6mm), including cutting, stamping, bending, welding and surface treatment, to process them into the metal structures or products you want.

Major Types of Sheet Metal

Stainless Steel Sheet

Grades such as 201, 304, 316, and 430 are widely used in kitchens, architectural decoration, and structural components.

Carbon Steel Sheet

Known for high strength and excellent wear resistance, commonly used in industrial and structural applications.

Galvanized Steel Sheet

Offers strong corrosion resistance, suitable for outdoor use, ventilation systems, and building exteriors.

Aluminum Sheet

Lightweight, corrosion-resistant, and highly conductive; used in aerospace, transportation, and electrical enclosures.

Copper Sheet

Features strong antibacterial properties and excellent electrical conductivity; commonly used in electrical systems and architectural decoration.

Brass Sheet

Attractive appearance and high formability, often used for artworks, decorative elements, and hardware components.

Titanium Sheet

High-strength and lightweight with outstanding corrosion resistance, ideal for high-end engineering and medical equipment.

How the Sheet Metal Fabrication Process Works？

Design & Material Selection

Before any cutting or forming begins, the part or product is designed (often with CAD/3D modeling), including dimensions, bend lines, hole positions, and tolerances.

Based on application requirements (strength, corrosion resistance, finish, budget, usage environment), the appropriate sheet-metal material is selected (e.g., stainless steel, carbon steel, aluminum, etc.).

Cutting

The raw metal sheet is cut to the required 2D shapes or “blanks.” Cutting methods vary depending on thickness, precision, and material: common techniques include laser cutting, water-jet cutting, plasma cutting, and shearing.

This step defines the outline of each part that will later be bent, formed, or assembled.

Punching

For parts that need holes, slots, cutouts, or special edge shapes, punching or notching may be applied to the blanks before forming. This helps create features like vents, mounting holes, slots, or flanges.

For mass production or repetitive patterns, stamping or blanking can be used.

Bending

The flat blanks are then shaped into 3D forms. This can involve bending (e.g., with press brakes), rolling (for curves or cylinder shapes), stamping, deep-drawing, or other forming processes, depending on the geometry.

Prope planning is important: bend sequences, grain direction (for metals with grain), bend radius, and tool selection all affect whether the final part meets design specs or cracks/distorts.

Assembly / Joining

If the final product requires multiple sheet-metal parts, they must be joined. Common joining methods include welding (MIG, TIG, spot welding), riveting, bolting, or mechanical fasteners, depending on requirements.

Welding is often used for permanent, strong joins; bolts/rivets or fasteners may be used when disassembly or modular assembly is needed.

Finishing (Surface Treatment & Final Touches)

After shaping and joining, parts are often finished to improve appearance, durability, and functionality. Finishing may include deburring (removing sharp edges or burrs), grinding/sanding weld seams, polishing, painting, powder coating, anodizing, or other surface treatments.

This step is especially important when the metal part will be exposed (architectural features, railings, furniture, visible surfaces) or used in harsh environments (corrosion resistance, hygiene, long-term durability).

Quality Inspection & Final Assembly / Packaging

Once fabrication and finishing are complete, each piece undergoes inspection: checking dimensions, weld quality, surface finish, fit-up of assemblies, and compliance with design specifications.

Finally, the product may be assembled with other components (if part of a larger structure), packaged, and prepared for delivery or installation.

Types Of Sheet Metal Work

Security & Driveway Gates

Security and driveway gates are essential components in residential estates, commercial buildings, industrial facilities, and parking systems. Fabricated using stainless steel, carbon steel, or aluminum, these gates must achieve a balance of durability, corrosion resistance, and visual appeal.

Why Sheet Metal Is Ideal for Gates

• Excellent structural strength

• Customizable patterns and laser-cut designs

• Long lifespan with minimal maintenance

• Compatibility with automation systems

Custom metal fabrication allows gates to be made in unique sizes, patterns, and finishes such as brushed, mirror, PVD colors, or powder coating.

Railings, Balustrades & Fencing

Railings and balustrades are widely used in hotels, commercial buildings, apartments, staircases, shopping malls, and public facilities. Stainless steel is especially preferred for its durability and modern appearance.

Fabrication characteristics

• TIG/MIG welding for seamless joints

• Bending and forming for curved railing systems

• Laser cutting for premium designs

• Safety-compliant structure for fall protection

These fabricated metal products enhance safety while adding architectural aesthetics.

Platforms & Landings

Industrial platforms and landings require strong steel structures to support heavy loads in factories, warehouses, logistics hubs, and construction sites.

Key fabrication requirements

• Precision cutting and welding

• Anti-slip grating or tread plates

• Structural reinforcements and load testing

• Compliance with building codes

Metal fabricators and welding experts ensure structural reliability through advanced welding techniques and engineering calculations.

Staircases & Balconies

Metal staircases and balconies combine design freedom with superior load-bearing capabilities. Steel's strength allows for minimal structure thickness while maintaining stability.

Common options

• Spiral staircases

• Industrial steel stair platforms

• Cantilever balcony structures

• Decorative stainless steel handrails

These can be highly customized using sheet metal fabrication technologies.

Cages & Shelters

Metal cages and shelters are used in security systems, industrial safety zones, equipment protection, warehouses, and animal facilities.

Fabrication highlights

• Strong structural framework

• Mesh or perforated sheet designs

• Solid welded construction for durability

Custom fabrication services ensure every cage matches its specific operational environment.

Commercial Kitchen Extraction Systems

In commercial kitchens—restaurants, hotels, cloud kitchens, catering facilities—extraction systems must be robust, easy to clean, and heat resistant.

Why stainless steel is preferred

• Hygienic and non-porous

• High resistance to heat and oil

• Easy to maintain

• Complies with food-grade standards

Fabricated hoods, filters, and ducting systems are typically made via sheet metal work using stainless steel 304 or 316.

Industrial Kitchen Fit-Outs

Industrial kitchens demand more than just hoods—they require a complete metal solution, including wall claddings, sinks, tables, and custom storage systems.

Typical components
