Design Services Offered: From Sketches or Samples to Engineered Solution
- DFM (Design for Manufacturing) Review — Free engineering analysis before production. We identify cost-saving opportunities, material alternatives, and tolerance optimization for stainless steel fabrication.
- Reverse Engineering — Send us a sample or damaged part. We measure, model, and fabricate an exact replacement in stainless steel.
- Material Consultation — Not sure which SS grade fits your application? Our engineers recommend the optimal grade based on corrosion requirements, temperature, and mechanical loads.
- Prototyping — Single-piece prototypes with full inspection reports. Test fit, form, and function before committing to production quantities.
Surface Finishing for Stainless Steel
- Passivation — Citric and nitric acid passivation per ASTM A967. Removes free iron, restores chromium oxide layer for maximum corrosion resistance.
- Electropolishing — Bright, ultra-smooth finish. Removes surface material for a mirror-like appearance. Ideal for pharmaceutical, semiconductor, and food-grade applications. Meets ASME BPE and 3-A sanitary standards.
- Mechanical Polishing — #4 brushed (satin), #8 mirror, hairline, and bead blast finishes available. Custom Ra values on request.
- Pickling — Chemical removal of heat tint and weld scale from fabricated assemblies. Restores full corrosion resistance after welding.
- PVD Coating — Physical Vapor Deposition for decorative colors (gold, black, rose gold, blue) on stainless steel. Scratch-resistant, fingerprint-resistant finish.
Simplified Process, Premium Quality
- Submit Your Drawing — Send your STEP, STP, DWG, or PDF file with dimensions, tolerances, and quantities. Include your preferred stainless steel grade and surface finish.
- Free Engineering Review — Our engineers analyze your design for manufacturability. We confirm material availability and recommend optimizations within 24 hours.
- Quote & Approval — You receive a detailed quotation with material cost, fabrication time, surface treatment, and shipping. No hidden fees.
- Production — Laser cutting, bending, welding, polishing, and passivation — all performed in-house. Quality gates at every stage.
- Inspection & Delivery — CMM dimensional verification, surface finish testing, material certification (EN 10204 3.1 / MTR). Packed and shipped via DHL, FedEx, or UPS.
Typical Stainless Steel Parts We Fabricate
- Custom Enclosures & Cabinets — IP65 / IP67 / NEMA 4X rated stainless steel enclosures for electrical, industrial, and outdoor applications.
- Brackets & Mounting Plates — Precision laser-cut and bent brackets with tapped holes, weld nuts, and hardware installation.
- Tanks & Hoppers — TIG-welded stainless steel tanks for food, chemical, and pharmaceutical processing. Ground and polished interior welds.
- Frames & Chassis — Welded structural frames from square tube, angle, and channel. Drilled and tapped mounting points per your drawing.
- Hygienic Components — Tri-clamp ferrules, sanitary tubing assemblies, and fittings for food, beverage, and biopharma industries.
- Architectural & Decorative Parts — Mirror-polished panels, handrails, cladding, and custom decorative elements in #8 or PVD finish.
