Our capabilities

Comprehensive Sheet Metal Fabrication & Contract Manufacturing Services

At Guanghao, we deliver turnkey engineering and manufacturing solutions tailored to meet the rigorous standards of global OEMs and industrial leaders. Utilizing state-of-the-art automation, high-precision machinery, and robust quality control systems, our full-service facility transforms raw metals into complex, high-tolerance components and fully assembled products.

Core Sheet Metal Fabrication Capabilities

Click on a category below to explore our specific advanced CNC machining and manufacturing capabilities:

Precision Laser Cutting

Equipped with high-power fiber laser cutting systems, we process complex geometries across a wide range of materials-including stainless steel, carbon steel, aluminum, and brass-with exceptional speed and smooth edge finish. Fiber laser technology minimizes heat-affected zones, reducing material distortion and eliminating the need for extensive secondary deburring.

CNC Sheet Metal Bending & Forming

Featuring multi-axis CNC press brakes and precision tooling, our multi-stage bending capabilities achieve consistent angles and intricate profiles on complex parts. Automated back-gauging systems ensure uniform bend accuracy and strict dimensional tolerance adherence across every production run.

Threading, Tapping & Chamfering

To prepare components for seamless mechanical assembly, we offer automated threading, blind-hole tapping, countersinking, and precision chamfering. These pre-assembly edge and hole treatments reduce stress concentrations, improve part fitment, and ensure structural integrity under load.

Surface Finishing & Treatment

Protecting your components against wear and corrosion while achieving the desired cosmetic appearance is integral to our process. Our comprehensive surface finishing options include industrial powder coating, wet painting, anodizing, electroplating, shot blasting, and manual or automated deburring and polishing.

Expanded Value-Added & Contract Manufacturing Services

Beyond standalone sheet metal parts, Guanghao offers end-to-end manufacturing solutions designed to streamline your supply chain, reduce lead times, and optimize overall production costs:

🏭 High-Speed Stamping & Metal Pressing

For high-volume production requiring maximum efficiency, our progressive stamping and punch press capabilities deliver high-speed blanking, piercing, and deep drawing with uncompromising batch-to-batch consistency.

🤖 Mechanical & Electromechanical Assembly

We go beyond part fabrication to deliver complete, ready-to-use sub-assemblies and final products. Our assembly line capabilities integrate hardware insertion (PEM fasteners, rivets, inserts), robotic and manual welding (TIG/MIG/Spot welding), wiring harness routing, and functional sub-system integration.

🌐 Full-Service Contract Manufacturing

Partnering with Guanghao as your contract manufacturer gives you access to complete supply chain management, design for manufacturability (DFM) analysis, rigorous quality assurance (APQP/PFMEA standards), custom packaging, and turnkey global logistics.

How It Works

From CAD to Delivered Metal Parts—Fast, Direct, and Transparent.


01. Upload CAD Models

Securely upload your 3D designs in STP, STEP, or SLDPRT formats to get started instantly.

02. Instant DFM & Quoting

Receive real-time pricing along with automated DFM feedback to optimize manufacturability and cost.

03. Place Direct Order

Configure your materials, finishes, and quantities, then order directly from the factory—no middleman markup.

04. Fast Global Delivery

Track your custom parts from our shop floor to your door with reliable, end-to-end logistics.

Surface Finishing & Post-Processing

Enhance durability and appearance with professional finishing and post-processing options.


Mill Finish

Unprocessed, raw surface directly from the mill - ideal for internal components or parts where appearance is not critical.

➔

Antirust Oiling

Temporary protective oil coating that prevents oxidation and corrosion during handling, storage, and transport.

➔

Brushed

Matte finish with a directional grain pattern that improves aesthetics, reduces glare, and hides minor scratches.

➔

Anodized

Electrochemical treatment that increases corrosion resistance, surface hardness, and allows for decorative color finishes.

➔

E-Coating

Electrostatically applied liquid coating that provides uniform coverage and durable corrosion resistance.

➔

Powder Coating

Durable, environmentally friendly coating available in multiple colors, providing excellent wear and corrosion resistance.

➔

Zinc

Electroplated zinc layer offering strong corrosion resistance and enhanced durability for steel parts.

➔

Passivation

Chemical treatment that removes surface contaminants and restores a protective oxide layer to improve corrosion resistance.

➔

Galvanized

Zinc-coated surface that delivers robust, long-term corrosion protection, especially for outdoor applications.

Frequently Asked Questions
Fast answers for engineers and procurement teams.
What files should I upload for an accurate quote?
Upload a 3D file (STEP/IGES) plus a PDF drawing that includes tolerances, critical dimensions, material/finish requirements, and quantity. If you have inspection or certification needs, include them in the RFQ.
Can you provide batch traceability and material certificates?
Yes. For eligible materials, we can provide traceability information and documentation such as material certificates, dimensional inspection reports, and declarations of conformity issued per production batch.
How do you handle DFM and cost reduction suggestions?
We review manufacturability and highlight cost drivers such as tight tolerances, difficult tool access, or finishing constraints. We then propose alternatives-like radius strategy, feature simplification, or process selection-to improve yield and reduce total cost without sacrificing function.
What quantities can you support: prototypes or production?
We support both. Many projects start with prototypes for validation, then move into pilot runs and production batches. During quoting, we align process choices to your current quantity and your expected ramp plan.
Do you offer surface finishing and post-processing?
We support a range of surface finishing options such as anodizing, plating, coating, blasting, and passivation. If a finish has compliance requirements, please specify them during RFQ so we can align the process and documentation scope.
How do you package and ship international orders?
We provide export-grade packaging options and can support common trade terms depending on your project. Share your destination, timeline, and packaging expectations in the RFQ so we can recommend the right approach.
