Secondary Fabrication & Customization Capabilities

Specialized machinery and in-house tooling to execute complex custom modifications for stainless steel profiles, posts, and components directly on the production line.

1. Fiber Laser Cutting & Slotting

CNC fiber lasers execute 3D tube cutting, miter cuts (0-60°), and U-channel glass slotting on stainless steel profiles with a clean edge tolerance of ≤ ±0.1mm.

2. Hole Punching & Drilling

Automated multi-head drilling and hydraulic punching for railing post passthrough holes, flow-drilled threaded sockets, and custom fitting mountings.

3. CNC Bending & Mandrel Rolling

Mandrel tube bending for smooth elbow curves without wall wrinkling or cross-section ovality, ideal for continuous handrails and curved structural profiles.

4. Laser Etching & Private Labeling

High-contrast laser logo etching on stainless steel parts, custom-printed protective film, end cap branding, and OEM distributor retail packaging.

Engineer's Checklist: 3 Common CAD Considerations in Custom Orders

To accelerate tooling setup and avoid production delays, ensure your engineering drawings account for the following stainless steel fabrication physics:

1. Bending Radius Limits

Centerline Radius (CLR) for mandrel tube bending should be ≥ 2x Outer Diameter. Tighter bends risk wall thinning or outer surface cracking.

2. Hole Distance to Edges

Hole edge distance to tube and profile ends should be ≥ 1.5x hole diameter. Placing punched holes too close to cut edges causes metal end deformation.

3. Weld Seam Orientation

For slot profiles or laser-punched posts, specify weld seam positioning in 3D STEP models so laser cuts avoid internal weld bead lines.

Custom Manufacturing & OEM/ODM FAQ

What 2D and 3D CAD file formats does your engineering department support?
We accept STEP (.stp), SolidWorks (.sldprt), DWG, and DXF vector files. If you only have physical sample parts, our CAD team can perform 3D scanning to reverse-engineer production drawings.
What is the lead time for custom tooling and prototype samples?
Engineering drawing review and feasibility evaluations are conducted rapidly upon submission. Once CAD models are signed off, custom prototype samples are typically produced and dispatched within 7 to 10 business days.
Can you provide non-disclosure agreements (NDA) to protect our proprietary design?
Yes. We routinely sign bilateral Non-Disclosure Agreements (NDA) with global B2B clients and original equipment manufacturers prior to reviewing proprietary CAD models or patent-pending profile designs.

Have a Custom Stainless Steel Profile or Laser Cutting Project?

Send us your CAD drawings or technical specifications. Our engineering team will perform a feasibility audit and provide an OEM proposal.
