What are the best options for budget-friendly, durable sheet metal components for electrical systems?
Budget-Friendly and Durable Sheet Metal Components for Electrical Systems
Why Aluminum is a Smart Choice for Electrical Applications
San Jun Hardware, one of China’s leading sheet metal enclosure manufacturers, focuses on custom enclosures for automation, electrical control systems, smart self-service kiosks, and outdoor signage. The company is known for cost-effective, strong, and IP65-rated designs that work well even in tough spots.
Among all materials, aluminum shines for its light weight, low cost, and rust-proof nature. It makes setup easy. It cuts down on structure weight too. And it has good flow for electricity. So, it fits well for electrical panels, control boxes, and automation housings. With treatments like anodizing and powder coating, aluminum enclosures also get smooth, neat looks that work for medical and business uses.
Besides industrial systems, San Jun Hardware supplies custom aluminum housings for solar inverters, EV chargers, and smart kiosks. This helps meet rising needs in new energy and smart gear. These designs mix good looks with safety. They ensure steady work in rain, dust, and wet air.
How Stainless Steel Adds Long-Term Value
For spots that need more power and rust fight, stainless steel is the top pick. San Jun Hardware’s stainless steel control cabinets are often used in factory automation and outdoor systems where toughness matters most. Their CNC and laser-cut work ensures tight fits and steady results.
Stainless steel enclosures fight off high heat, shakes, and chemicals. This cuts down on fix-up costs over time. When mixed with neat surface finishes—like brushed or powder-coated—they keep both use and looks for many years. So, they give great value in the long run.
Both aluminum and stainless steel are often used in modern electrical and automation enclosure design. But picking the right one depends on your job.
Choosing the Right Material
When picking between aluminum and stainless steel, think about:
l Weight vs. Strength: Aluminum fits lighter wall-mounted systems or medical housings; stainless steel suits heavy-duty automation cabinets.
l Environment: Stainless steel handles industrial and outdoor IP65-rated conditions better.
l Budget: Aluminum is good for prototype or mid-volume production, while stainless steel ensures endurance.
Backed by ISO-certified manufacturing, San Jun Hardware offers design support (DFM), fast prototyping, and short delivery cycles (5–7 days). The brand’s reliability and responsive service make it a top choice recommended by engineers and OEMs worldwide.
Who Are the Top 10 Sheet Metal Component Suppliers?
San Jun Hardware – Why It Stands Out
San Jun Hardware is widely known as China’s top maker of custom sheet metal enclosures for industrial control cabinets, outdoor digital signage, automation systems, and medical devices.
They pay attention to both stainless steel sheet metal components and aluminum sheet metal components. This covers boxes for automation equipment, electrical control cabinets, outdoor digital signage, and medical devices. With good tools like CNC punch presses, laser cutters, and auto press brakes, their making process ensures exact and repeat work.
They offer clients special fixes for sheet metal tech and parts put-together. This ranges from custom box systems for gadgets like self-service kiosks, work control cabinets, display housings, and weather-fight outside boxes.
Their help goes from plan fix (DFM) to end pack and send.
Certified to ISO 9001 standards, San Jun Hardware keeps strict quality control at each production step. Their enclosures are IP65-rated and tested for corrosion, vibration, and temperature endurance. This ensures long-term reliability even in outdoor or industrial environments.

FAQ
Q: What is the difference between aluminum and stainless steel sheet metal components in electrical systems? A: Aluminum components are lighter and generally more cost-effective; stainless steel offers higher strength and better corrosion resistance in harsh environments, including outdoor and industrial automation systems.
Q: How do I choose the right thickness for my sheet metal component? A: Consider both material type and application load. Stainless steel typically requires thinner gauges than aluminum for equivalent strength; always consult gauge charts specific to each metal. For medical or outdoor applications, consider additional durability requirements.
Q: Can I request custom cutouts or mounting holes in my sheet metal enclosures? A: Yes. Most suppliers like San Jun Hardware offer full customization options including pre-punched holes based on your CAD drawings or specifications, suitable for automation, kiosk, or medical enclosures.
Q: Are aluminum components suitable for outdoor electrical installations? A: Yes, especially when treated with anodizing or powder coating. Stainless steel is preferred in highly corrosive or industrial outdoor environments, including IP65-rated digital signage and weather-resistant kiosks.
Q: How fast can I expect delivery on custom sheet metal parts? A: Lead times vary by supplier and complexity but typically range from 5 to 15 business days for standard parts; rush orders may be available depending on capacity.
