Protect your investment and meet application demands. Our engineered finishes solve corrosion, wear, and compliance challenges—extending part life and ensuring performance. For specialized needs, select "Custom Finish" and detail your requirements for a tailored solution.
As Machined
Solve immediate prototyping and functional part needs. This finish delivers parts fastest and at lowest cost, ideal for non-cosmetic components where speed to test and budget are critical.
Anodizing
Eliminate corrosion and wear on aluminum parts. Our anodizing creates a hard, protective layer that significantly extends part life and allows for durable, color-matched aesthetics.
Polishing
Achieve a flawless, high-gloss appearance. This process removes micro-imperfections, enhancing reflectivity, cleanability, and premium visual appeal for consumer and architectural components.
Sand Blasting
Create a uniform, matte surface and prepare for coating. This process effectively cleans, deburrs, and textures parts, providing excellent adhesion for paints and a consistent non-reflective finish.
Brushed Finish
Conceal daily wear and fingerprints. The directional satin texture minimizes the visibility of scratches, offering a sophisticated, tactile surface that resists marking.
Powder Coating
Apply a durable, vibrant, and uniform protective shield. This thick, thermoset layer provides exceptional impact, UV, and chemical resistance in a wide range of colors and textures.
Electroplating
Enhance surface properties with a bonded metal layer. Add hardness, corrosion resistance, conductivity, or a decorative chrome, nickel, or zinc finish to base materials.
Black Oxide
Improve corrosion resistance and light absorption on steel. This conversion coating adds a dark, attractive finish with minimal dimensional change, ideal for tools and mechanical components.
Passivation
Restore and maximize the innate corrosion resistance of stainless steel. This chemical process removes free iron, preventing surface rust and ensuring long-term performance in demanding environments.
Electropolishing
Smooth, deburr, and ultra-clean stainless steel. This advanced process polishes at a microscopic level, improving corrosion resistance and creating a bright, hygienic, premium surface.
Alodine (Chromate Conversion) Coating
Protect aluminum with a superior conductive primer. This coating provides excellent corrosion resistance and dramatically improves paint adhesion, essential for aerospace and automotive applications.
Hot Dip Galvanizing
Guard structural steel against harsh, long-term corrosion. The thick, bonded zinc layer provides sacrificial cathodic protection, ensuring decades of service in outdoor and industrial settings.

Tolerances | Specifications |
|---|---|
General Tolerances | Metals: ISO 2768-m (Medium) |
Cutting Feature | ±0.1mm (0.0039") – Ensures perfect fit and assembly. |
Bend Angle | ±0.5° – Guarantees dimensional accuracy for enclosures and brackets. |
Bend to Edge | ±0.15mm (0.0059") – Solves alignment issues in multi-part assemblies. |
Hole to Bend | ±0.2mm (0.0079") – Maintains functionality of mounted components. |
All critical dimensions are verified with calibrated instruments and documented for traceability in your project's quality report.
Sheet Metal Fabrication Design Guidelines
Engineer your parts for seamless manufacturing. Our design guidelines are engineered to prevent common fabrication issues, reduce costs, and accelerate your time-to-market. Adhering to these parameters ensures parts that are not only manufacturable but also robust, reliable, and delivered on schedule.
| Feature | Recommended Design Value (MT = Material Thickness) | Core Benefit & Consideration |
|---|---|---|
| Minimum Bend Radius | 1×MT | Prevents material cracking. Softer materials (e.g., 5052 Al) can go to 0.5×MT; harder ones (e.g., stainless steel) may require ≥2×MT. |
| Hole-to-Edge Distance | ≥2×MT | Prevents edge tear-out or deformation during punching or laser cutting, ensuring part integrity. |
| Hole-to-Hole Distance | ≥2.5×MT | Maintains structural strength between holes. Increase to ≥6×MT for high-density patterns or heavy loads. |
| Bend-to-Hole Distance | ≥2.5×MT | Prevents hole distortion during bending. For tapped or critical holes, increase to ≥4×MT. |
| Countersink-to-Edge Distance | ≥3×MT | Ensures material integrity around the countersink, preventing breakout and ensuring flush fastener seating. |
| Minimum Flange Width | 4×MT (or 6mm) | Enables reliable bending. Provides sufficient grip for the press brake die to form a consistent, accurate bend. |
| Relief Notch Width | ≥1×MT | Eliminates material stress and tearing at inside bend intersections, required for perpendicular bends meeting at a corner. |
| Corner Fillet Radius | ≥0.5×MT | Improves manufacturability and stress distribution. A radius is strongly preferred over a sharp corner for most materials. |
