Materials Selection for Sheet Metal Frames
The longevity of your frame depends on matching the right substrate to its operating environment. At ShincoFab, we stock a wide range of certified metals to ensure your sheet metal frame performs as intended, regardless of where in the world it is deployed.
Frame Material Options (Alloys)
Aluminum (5052 / 6061): The premier choice for high strength-to-weight ratios. Essential for aerospace components and handheld device frames where reducing mass without sacrificing rigidity is critical.
Carbon Steel (CR / HR): Â The industry standard for cost-effective adaptability. Provides maximum tensile strength for heavy-duty structural applications where weight is less of a concern.
Stainless Steel (304 / 316):Â Engineered for harsh environments. Offers superior hygiene and natural corrosion resistance, making it mandatory for food processing, medical devices, and chemical plant frames.
Protective Finishes & Coatings
Raw metal is just the beginning. Our finishing services extend the lifecycle of your frames and ensure they meet aesthetic standards.
Galvanizing:Â A robust sacrificial zinc coating that self-heals against scratches. Critical for **outdoor sheet metal frames** and agricultural equipment exposed to moisture.
Powder Coating: A baked-on polymer finish that offers superior durability compared to wet paint. Provides electrical insulation, chip resistance, and custom color branding for consumer-facing enclosures.
Why We Are Your Ideal Frame Manufacturing Partner
Outsourcing critical structural components overseas shouldn’t be a gamble. Partnering with ShincoFab means working directly with the source. We execute your engineering requirements on our own shop floor in China, giving you total visibility and control over production. From controlling thermal distortion generally to ensuring material traceability, here is how our factory adds value to every frame we manufacture for our global customers.
Controlling Weld Distortion
Flatness and squareness are non-negotiable. While others struggle with heat warping, we engineer process controls to prevent it by utilizing custom modular fixturing and distinct welding sequences to manage thermal expansion. We validate this precision with rigorous QC using calibrated gauges and CMM validation, providing you with comprehensive First Article Inspection (FAI) reports to ensure your mating parts align perfectly during final assembly.
Cost-Reducing DFM Analysis
We don’t just build to print; we optimize for manufacturing. Our engineering team reviews your CAD files within 24 hours to suggest smart structural changes—like self-locating tab-and-slot designs, that reduce reliance on expensive fixtures and cut assembly time. The result is a lighter, stronger sheet metal frame with fewer inspection points and lower material costs, without ever compromising structural integrity.
Complete End-to-End Fabrication
Stop managing multiple vendors for one project. We handle the entire fabrication lifecycle under one roof, synchronizing cutting, forming, welding, and hardware insertion in our ERP system to eliminate bottlenecks. We also manage surface treatments like powder coating or zinc plating and deliver your frames fully kitted with fasteners, labeled by sub-assembly, and ready for immediate installation on your production line.
Scalable & Transparent Production
Deadlines dictate your profit, so we align our production capacity with your schedule to offer total transparency. Whether you need a single rapid prototype frame in 3 days or a 500-unit pilot run, our shop floor scheduling adapts to your volume. We remove the “black box” of manufacturing by assigning you a dedicated project manager who provides honest timelines, weekly photo updates, and immediate alerts if design adjustments are needed.
Certified Material Traceability
A frame is only as good as the metal it’s made of. We leverage strong mill relationships to stock standard gauges of Aluminum, Stainless Steel, and CR Steel, ensuring availability and consistent quality. Full traceability is guaranteed on every order; we provide Material Test Reports (MTRs) and Certificates of Conformance (CoC) with every shipment, ensuring your compliance requirements are met before the parts even hit your dock.

Frequently Asked Questions
Get straight answers to your technical and commercial questions. From controlling weld distortion to shipping heavy weldments globally, here are the critical details you need to know before working with ShincoFab.
What logical tolerances can you hold on welded frames?
For standard welded structures, we typically hold ISO 2768-m (medium) class tolerances. However, for precision chassis or machined surfaces, we can achieve tighter tolerances (e.g., ±0.005″ / 0.1mm) using post-weld machining and precision fixturing. Please specify critical dimensions in your 2D drawings.
What file formats do you need to provide a quote?
To get an accurate quote within 24 hours, please provide:
- 3D Model: STEP (.stp) or IGES (.igs) files for calculating material volume and bending interference.
- 2D Drawing: PDF files indicating critical tolerances, thread types (UNC/Metric), and finish requirements.
- Bill of Materials (BOM): If assembly hardware is required.
Do you have a Minimum Order Quantity (MOQ)?
No. As a factory-direct partner, we are set up for flexibility. We handle everything from single-unit prototypes (beta builds) to high-volume production runs (5,000+ units). Keep in mind that unit costs decrease significantly with higher volume due to setup amortization.
How do you control weld distortion on large frames?
Distortion control is our specialty. We utilize modular fixturing tables and clamping jigs to secure parts before welding. Our welders use specific sequencing techniques (such as stitch welding and back-stepping) to disperse heat accumulation. For high-precision bases, we also offer stress-relieving heat treatment services.
Can you source specific materials and provide traceability?
Yes. We stock standard Aluminum (5052/6061), Stainless Steel (304/316), and Carbon Steel (CR/HR). If your BOM calls for exotic alloys, we can source them through our mill partners. Material Test Reports (MTRs)Â and ROHS/REACH compliance certifications are available upon request for every shipment.
How are large frames packaged for shipping?
Shipping damage is unacceptable. Small chassis are wrapped in EPE foam and boxed individually. For heavy machine bases and large frames, we build custom wooden crates or skids bolted directly to the struct, ensuring they remain immobile during transit. We can also accommodate reusable returnable packaging for recurring local orders.
What is your standard lead time?
- Quoting: Within 24 hours.
- Prototypes: Typically 3–7 business days, depending on material availability and finish.
- Production: Typically 2–3 weeks.
