Our expertise in high-mix, low-volume, repeatable production makes us the ideal partner for companies requiring diverse component types with consistent quality across repeat orders.
Let’s break down the essential elements of metal fabrication—parts, weldments, and assemblies—and explore the wide range of components that power industries from medical equipment to industrial automation.
Precision Fabricated Sheet Metal Parts
At the heart of every metal fabrication project is the individual sheet metal part. These components are fabricated from stainless steel, aluminum, or other metals and can either function as standalone items or serve as building blocks for larger assemblies.
For example:
- Standalone Parts: Brackets, panels, and hinges that perform specific functions within equipment or machinery
- Components in Assemblies: Individual parts that are welded or fastened together to form complex structures like control cabinets, equipment enclosures, or material handling systems
Each sheet metal part is crafted with precision to meet exact specifications, forming the foundation for weldments and assemblies. Our ISO 9001:2015 certified processes ensure consistency across production runs, whether you need 50 units or 5,000.
Weldments: Strength Through Integration
Weldments are created by joining multiple metal parts together through welding processes like spot welding, robotic MIG welding, or TIG welding. These integrated structures provide durability and structural integrity, making them essential for equipment that must withstand demanding industrial environments.
Examples of weldments include:
- Equipment Frames: Structural frameworks for industrial machinery and automation systems
- Welded Enclosures: Custom-fabricated panels welded together to house sensitive electronics or control systems
- Chassis Assemblies: Integrated base structures for equipment and machinery
Weldments serve as intermediate structures that can be further enhanced with additional components—mounting hardware, access panels, cable management—to create complete, functional assemblies.
Metal Assemblies: Complete Integrated Solutions
A metal assembly is the finished product that combines individual parts and weldments into a complete, functional unit. Assemblies can range from relatively simple products to sophisticated multi-component systems with complex integration requirements.
Key processes for creating assemblies include:
- Welding: For strong, permanent connections that maintain structural integrity
- Fastening or Riveting: When serviceability, modularity, or field replacement is required
- Hardware Integration: Incorporating hinges, latches, handles, and mounting components
- Sub-Assembly Integration: Combining multiple weldments and components into complete systems
Common examples across industries:
- Server Racks and Equipment Cabinets: Used in IT infrastructure and telecommunications
- Medical Equipment Carts: Custom-designed for mobility and functionality in healthcare settings
- Control Enclosures: Housing electrical components, PLCs, and operator interfaces for industrial automation
- Test Equipment Chassis: Precision frameworks for laboratory and manufacturing test systems
Assemblies are highly versatile and can be tailored to meet the specific requirements of diverse industries, ensuring the durability, functionality, and precision that OEM partners demand.
Core Metal Fabrication Components and Products
EVS Metal manufactures a comprehensive range of components and finished products. Our expertise in high-mix, low-volume, repeatable production means we can efficiently produce diverse component types while maintaining the consistency and quality standards essential for OEM relationships.
Structural & Mounting Components
Fabricated Metal Brackets
Metal brackets are among the most versatile sheet metal components, fabricated in sizes ranging from small enclosure mounting brackets to substantial structural supports. EVS Metal has fabricated brackets for projects ranging from precision electronics enclosures to major infrastructure—past projects have included structural steel brackets for the Tappan Zee Bridge.
Brackets come in various configurations designed for specific mounting requirements:
- Z-Brackets: Used for mounting offset parallel surfaces within enclosures and equipment
- Gusset Brackets: Triangular reinforcement brackets that provide additional strength and rigidity in weldments and assemblies
- L-Brackets: Standard right-angle brackets for mounting vertical components to horizontal surfaces, commonly used for shelf mounting within enclosures
- Offset Brackets: Similar to Z-brackets, designed for specific spacing requirements
- U-Brackets: Used for mounting parallel surfaces together in equipment assemblies
Industrial Metal Supports
Metal supports encompass structural steel components used in construction and heavy industrial applications. These include beams, poles, structural brackets, pipes, and tubes designed to carry significant loads while maintaining dimensional stability.
Commercial Metal Frames
Metal frames are weldments and assemblies available in a wide range of sizes and configurations. Structural steel frames serve construction and heavy industrial applications, while smaller frames—doorway frames, equipment mounting frames, cart frames—are manufactured using stainless steel or aluminum depending on environmental requirements and weight considerations.
Fabricated Metal Arms
Metal arms range from simple single-component parts to complex multi-component assemblies, depending on application requirements. These include manipulator arms in vertical or horizontal orientations with rocker or double-rocker suspensions, powered by electric, pneumatic, or hydraulic systems. Other applications include mounting arms for industrial lighting, architectural lighting systems, and specialized equipment positioning.
Metal Hinges
Metal hinges enable rotational movement between components of an assembly, most commonly for doors, lids, and access panels on cabinets and enclosures. Hinges can be fabricated from stainless steel or aluminum—aluminum offers lighter weight and corrosion resistance for humid environments or outdoor applications, while stainless steel provides superior strength for heavy doors or high-cycle applications.
Enclosure & Housing Solutions
Fabricated Metal Enclosures
Sheet metal enclosures represent one of the largest product categories, encompassing the end products of countless part, weldment, and assembly combinations. Enclosures are most commonly fabricated from aluminum or stainless steel for commercial and industrial applications.
Examples include equipment cabinets, storage containers, protective cages, and specialized carts like those used in medical facilities for transporting supplies between operating rooms. The unifying characteristic is that enclosures are designed to house, store, or protect items—from computer servers and network equipment to industrial controls and sensitive instrumentation.
Metal Boxes
Metal boxes are sheet metal enclosures with five or six sides (the sixth being a cover, lid, or door). They’re manufactured from stainless steel, aluminum, or other metals in any required size. Box enclosures range from simple single-wall constructions to complex assemblies incorporating mounting hardware, ventilation, and integrated components.
Examples include electrical junction boxes, hinged access boxes, latched equipment boxes, and toolboxes. The distinction between “box” and “enclosure” often comes down to complexity and integration—boxes tend to be simpler structures while enclosures may incorporate multiple sub-assemblies.
Commercial Metal Cabinets
Metal cabinets are essentially box enclosures with doors attached via brackets and hinges, fabricated in sizes ranging from compact wall-mount units to large floor-standing systems. Smaller cabinets include medical supply carts with integrated casters for mobility, while larger cabinets encompass equipment storage lockers and secure storage systems with integrated lock mechanisms.
Cabinets frequently incorporate internal racks, adjustable shelves, or sliding drawer systems depending on their intended application—electrical control cabinets, network equipment cabinets, parts storage cabinets, and secure document storage all have distinct internal configurations.
Equipment Chassis
A chassis is the structural framework or housing for equipment and machinery, providing the foundation for mounting electronic components, mechanical systems, or integrated assemblies. Chassis can be simple open-frame structures or enclosed housings depending on environmental protection requirements.
Common applications include electronics chassis for test equipment, industrial computer chassis for harsh environments, and machinery base frames for automation systems.
Equipment Housings
Housings are protective enclosures designed to specific equipment requirements—motor housings that protect electrical motors from environmental contamination, sensor housings that enable precise instrument positioning while providing environmental protection, and equipment housings that integrate mounting, ventilation, and access requirements.
The distinction between housings and enclosures is often application-specific—housings typically conform more closely to the equipment they protect, while enclosures tend to be more standardized structures.
Commercial Metal Panels
Sheet metal panels serve two distinct purposes in metal fabrication. Architectural panels are primarily decorative, used in commercial building facades and interior design applications. However, the majority of fabricated panels are functional components—access panels for equipment enclosures, electrical panels for control cabinets, and mounting panels for electronic components.
A common example is the electrical panel found in nearly every commercial building—a fabricated assembly of panels, covers, and mounting components that houses circuit breakers and electrical distribution equipment.
Equipment & Infrastructure
Equipment Racks and Server Racks
Equipment racks are a specialty area for EVS Metal, dating back to the company’s origins in electronics manufacturing. Modern equipment racks serve diverse applications—19-inch server racks for IT infrastructure, telecommunications equipment racks, industrial control system racks, and laboratory equipment racks.
Racks can be open-frame structures for equipment rooms with environmental control, or fully enclosed rack cabinets for office environments or outdoor installations. Custom rack configurations accommodate specific equipment layouts, cable management requirements, and cooling system integration.
Machine Guards and Safety Guards
Machine guards and safety guards are protective barriers fabricated to OSHA and ANSI safety standards, designed to prevent operator contact with moving machinery while maintaining equipment visibility and access for maintenance. Applications include guarding for robotic work cells, CNC machine tool guarding, conveyor system guards, and industrial equipment barriers.
Control Consoles and Operator Stations
Control consoles are integrated assemblies that combine structural framework, mounting surfaces, and equipment housing to create complete operator interface stations. These range from simple single-operator stands to sophisticated multi-station control rooms for industrial processes, manufacturing lines, or facility monitoring systems.
Storage & Material Handling
Industrial Metal Containers
Commercial metal containers include intermodal shipping containers used for ocean freight and rail transport, often called “dry” shipping containers. Other container types include portable storage units and modular storage “pods” for construction sites and industrial facilities.
Smaller metal containers serve warehouse and industrial environments—modular containers designed for stacking or rack mounting, parts storage containers with integrated dividers, and material handling containers designed for forklift or overhead crane transport.
Commercial Metal Bins
Metal bins are open-top containers used for material storage, waste management, and material handling. Large industrial bins serve construction sites for waste consolidation and material transport. Some industrial bins incorporate covers and locking mechanisms for securing valuable equipment that cannot be easily transported daily—useful for road construction projects requiring long-term equipment staging.
Smaller metal bins serve warehouse and manufacturing environments, often stackable or designed for rack storage to maximize space utilization. These include parts bins, storage bins, and material handling bins for work-in-progress inventory.
Metal Lids and Covers
Metal lids and covers range from simple flat covers to complex assemblies incorporating hinges, latches, and gaskets for environmental sealing. Applications include equipment access covers, electrical enclosure covers, inspection port covers, and storage container lids. The distinction between lids and doors often relates to orientation—lids typically cover top openings while doors cover side or front access points.
Metal Trays and Shelves
Fabricated metal trays and shelves serve both equipment integration and storage applications. Equipment trays include slide-out server trays for rack-mount installations, component mounting trays within enclosures, and cable management trays for wire routing. Storage shelves range from light-duty parts storage to heavy-duty industrial racking designed for substantial load capacity.
