Custom Metal Brackets
Discover high-quality custom metal brackets designed for durability, precision fit, and rapid delivery. Whether you need prototypes or volume production, our expert fabrication services ensure your custom metal brackets meet the toughest standards and unique project needs.
Why You Need Custom Metal Brackets
Off-the-shelf hardware often forces engineers to compromise—leading to wasted internal space, unnecessary weight, or suboptimal connection points. At ShincoFab, we believe the hardware should adapt to your design, not the other way around. Custom metal brackets serve as the critical link that ensures the structural integrity and functionality of your final assembly, allowing you to navigate complex geometries and route around existing motors or cabling to utilize every millimeter of available space.
Beyond unique geometry, custom fabrication optimizes your product’s performance and manufacturability. Instead of over-engineering with heavy standard parts, you can specify the exact material thickness and alloy needed to meet load requirements without excess mass. We deliver these components assembly-ready—complete with pre-installed PEM® fasteners, precise hole patterns, and integrated grounding points—eliminating secondary operations and significantly reducing your installation time and labor costs on the production floor.
Common Bracket Styles We Manufacture
At ShincoFab, we fabricate a comprehensive range of custom sheet metal brackets. While every project has unique requirements, most designs are built upon these fundamental geometries. Whether you need a simple L-bracket or a complex reinforced assembly, our manufacturing capabilities allow us to adapt these standard styles to your specific dimensions, material needs, and load requirements.
L-Brackets
As the essential workhorse of sheet metal design, L-brackets are formed by a single 90-degree bend to connect perpendicular surfaces seamlessly. They are the most versatile solution for mounting horizontal shelves to vertical walls, connecting chassis panels, and reinforcing corners. For applications requiring increased load capacity, ShincoFab can easily integrate welded or formed gussets into the bend design.
Z-Brackets
Characterized by two parallel bends usually in opposite directions, Z-brackets create a “step” geometry specifically designed for mounting surfaces on different planes. This profile is ideal for bridging offset panels, organizing cables, or creating airflow clearance behind components. They are frequently used in signage and architectural panels where hidden fastening is required to maintain a clean aesthetic.
U-Brackets
Formed with two bends in the same direction to create a “U” or “C” channel, these brackets provide excellent securement and structural stability. This shape is perfect for encapsulating components like capacitors and batteries, clamping pipes, or creating double-shear support points for pivoting joints. We can precisely customize the leg length and width to fit your specific manufacturing tolerances.
Gusset Brackets
Engineered for environments where standard bends might deform under stress, Gusset Brackets feature a triangular metal rib welded or formed directly into the bend. This reinforcement significantly increases rigidity, making them essential for heavy industrial machinery, motor mounts, and structural frameworks susceptible to vibration. ShincoFab offers both welded gussets for maximum strength and formed ribs for cost-efficiency.
Hat Brackets
Resembling a top hat with two outward-facing flanges, this “Omega” profile offers a stable, raised mounting platform while creating a functional cavity underneath. This space is excellent for wire management or heat dissipation by raising hot components off the base. Additionally, Hat Brackets can act as effective stiffeners to strengthen long, flat sheet metal panels against flexing.
Flat Brackets
Simple yet crucial, Flat Brackets are unbent metal strips featuring custom hole patterns designed for joining components on the same plane. They are the go-to solution for connecting adjacent flat surfaces, reinforcing weak joints, or acting as spacer plates to distribute loads. For a flush and seamless finish, we can manufacture these plates with precision countersunk holes.
Supported Materials for Custom Metal Brackets
At ShincoFab, choosing the right material is just as critical as the design itself. Whether your brackets need to withstand marine corrosion, support heavy industrial loads, or conduct electricity, we stock a vast inventory of metal alloys to meet your specific performance requirements.
Stainless Steel
The gold standard for durability and hygiene.
- 304 Stainless Steel: The most common choice for general corrosion resistance and indoor/outdoor utility.

- Brass (C260): Offers a unique combination of acoustic properties, corrosion resistance, and a premium gold-like aesthetic for decorative hardware.
Surface Finishing Options
The raw metal is just the beginning. Our comprehensive finishing services ensure your custom brackets not only look professional but are chemically engineered to last in their operating environment.
Protective Coatings
- Anodizing (Type II & III): Primarily for aluminum, this electrochemical process hardens the surface and prevents oxidation. Available in clear, black, or custom colors.
- Chemical Conversion Film (Chem Film): A chromate coating that creates a corrosion-resistant surface on aluminum while maintaining electrical conductivity (Mil-Spec compliant).
- Zinc Plating: A sacrificial coating for steel that acts as a barrier against rust, available in clear (silver) or yellow chromate.
- Passivation: A deep-cleaning process for stainless steel that removes surface contaminants to enhance its natural corrosion resistance.
Aesthetic & Durable Finishes
- Powder Coating: A highly durable, dry finishing process available in hundreds of RAL colors and textures (matte, gloss, sandtex). It provides a thicker, more protective layer than standard wet paint.
- Bead Blasting: Sprays fine beads at the metal to remove tool marks and create a uniform, matte texture.
- Brushing/Graining: Adds a directional grain pattern to stainless steel or aluminum for a premium, fingerprint-resistant cosmetic look.
- Laser Marking & Silkscreening: For branding, serialization, labeling port locations, or adding safety warnings directly onto your brackets.
Customization and Manufacturing Capabilities
End-to-End Precision Fabrication
At ShincoFab, we combine state-of-the-art automation with skilled craftsmanship to transform your CAD files into functional parts. Our integrated manufacturing process allows us to maintain strict quality control at every stage of production, ensuring your brackets meet precise tolerances whether standard or complex.

What is the difference between Laser Cutting and Stamping for brackets?
Laser cutting is ideal for prototypes and low-to-medium volume production as it requires no tooling costs and offers high flexibility. Metal stamping (using hard dies) is more cost-effective for high-volume runs (usually 5,000+ parts) because it dramatically reduces the per-unit cost, though it involves an upfront investment for the mold. ShincoFab offers both solutions to scale with your project growth.
What standard tolerances can ShincoFab hold for custom brackets?
For general sheet metal features, we typically hold tolerances of ±0.005″ (±0.127mm) for laser cutting and punching. For bending angles, our standard tolerance is ±0.5 degrees. If your project requires tighter precision for critical mating surfaces, please specify this in your drawing, and our engineering team will evaluate the feasibility.
I don't have a 3D CAD file. can you work from a sketch or sample?
Absolutely. Many of our clients start with a hand-drawn sketch or a physical sample. Our design team offers Reverse Engineering and CAD services to convert your concepts into manufacturable 3D models (STEP/SolidWorks) and 2D fabrication drawings.
Do you offer prototyping services? What is the MOQ?
We have No Minimum Order Quantity (MOQ). We specialize in “Quantity 1” prototyping to help you validate form, fit, and function before committing to production. Whether you need a single fast-turn L-bracket or 50 complex sub-assemblies, our process is flexible enough to accommodate your needs.
How do I choose the right material and finish for outdoor applications?
For outdoor brackets exposed to moisture or UV, we generally recommend Stainless Steel 304/316 for natural corrosion resistance unless weight is a concern. If utilizing Aluminum (5052/6061) or Carbon Steel, a protective finish is mandatory. Powder Coating provides excellent UV protection and durability, while Anodizing (for aluminum) or Galvanizing (for steel) offers superior corrosion resistance.
Can you install fasteners like nuts or studs into the brackets?
Yes, hardware insertion is a standard part of our process. We stock a wide range of PEM® fasteners (clinch nuts, studs, standoffs) and use automated insertion presses to install them permanently. This simplifies your final assembly and provides strong load-bearing threads in thin sheet metal.
How long does it typically take to manufacture custom brackets?
Our standard lead time for prototypes and small batches (under 50 pieces) is typically 3–5 business days. For larger production runs or orders requiring specialized finishing (like complex plating or silk screening), lead times typically range from 2–3 weeks. We also offer expedited options for urgent deadlines.
