Custom Stainless Steel Fabrication for OEM Projects
Standard stainless steel sheets often require additional processing before they can be installed or assembled into finished products.
Dongmeng Group transforms stainless steel sheet and plate into ready-to-use parts, panels, brackets, enclosures and welded assemblies. Components can be manufactured according to customer drawings, physical samples or project specifications.
Our OEM stainless steel fabrication services are suitable for:
New product prototypes
Replacement components
Customized machinery parts
Architectural metal panels
Stainless steel enclosures
Food equipment components
Decorative stainless steel products
Repeated production orders
Multi-part welded assemblies
Our team reviews the material grade, sheet thickness, bend radius, welding position, tolerance, surface direction and packaging requirements before production.
This helps reduce fabrication risks and improves consistency from prototype to volume production.
Stainless Steel Fabrication Capabilities
Precision Laser Cutting
Laser cutting is suitable for producing stainless steel profiles, holes, slots, decorative patterns and complex part geometries.
Our laser cutting service supports:
Custom profiles based on CAD drawings
Straight and curved cutting
Holes, slots and internal contours
Small and large stainless steel parts
Prototype and repeated batch production
Part identification and order sorting
Deburring and edge treatment after cutting
Cutting parameters are selected according to the stainless steel grade, thickness, required edge quality and final application.
Where necessary, cut edges can be deburred, polished or prepared for bending and welding.
CNC Bending and Forming
CNC press brake bending is available for custom brackets, channels, covers, boxes, frames, cabinets and structural components.
Typical forming options include:
V-bending
U-shaped profiles
L-shaped profiles
Box and enclosure forming
Multi-angle bending
Hemming and edge folding
Customized bend radius
Repeated production using controlled programs
Bend allowance, material springback, grain direction and surface protection are reviewed before fabrication.
For appearance-sensitive stainless steel parts, protective film and suitable tooling can be used to reduce scratches and pressure marks.
Punching and Stamping
Punching and stamping can be used for ventilation holes, mounting holes, perforated areas, slots, formed features and repeated production parts.
Available options include:
CNC punching
Custom hole patterns
Louvers and ventilation openings
Mounting holes
Perforated panels
Simple formed features
Progressive or dedicated tooling for suitable volume orders
Tooling requirements and production costs are evaluated according to the part design and order quantity.
Stainless Steel Welding
Dongmeng Group supports stainless steel welding for individual parts and multi-component assemblies.
Available welding methods include:
TIG welding
MIG welding
Spot welding
Laser welding
Continuous seam welding
Tack welding
Custom welded assembly
Welds can be ground, blended, polished or passivated according to the required appearance and corrosion-resistance requirements.
For fabricated enclosures, tanks or equipment components, leak testing and additional inspection can be arranged according to the drawing and application.
Surface Finishing and Polishing
Surface finish has a direct effect on appearance, cleanability, corrosion performance and installation results.
Available stainless steel finishes include:
2B mill finish
BA bright annealed finish
No.4 brushed finish
Hairline finish
Satin finish
Polished finish
Mirror and 8K mirror finish
PVD gold, black, bronze, rose gold and champagne colors
Weld grinding and blending
Pickling and passivation where required
For brushed and hairline components, the surface direction should be marked on the drawing.
Protective film can remain on the visible surface during cutting, bending, assembly and shipping.
Assembly and Secondary Processing
In addition to individual sheet metal parts, we can support secondary processing and assembly.
Services may include:
Fastener installation
Riveting
Bolt and nut assembly
Multi-part welding
Frame assembly
Cabinet and enclosure assembly
Edge deburring
Grinding and polishing
Protective film application
Custom labeling and packaging
Providing assembled or semi-assembled components can reduce the number of suppliers involved in your project.
Stainless Steel Materials Available
304 and 304L Stainless Steel
304 and 304L are widely used for industrial equipment, kitchen systems, architectural components, cabinets, brackets and general-purpose fabricated parts.
They offer a practical balance of corrosion resistance, formability, weldability and cost.
316 and 316L Stainless Steel
316 and 316L contain molybdenum and are commonly selected for marine, chemical, coastal, food processing and higher-corrosion environments.
316L is particularly suitable for projects involving extensive welding or strict corrosion-resistance requirements.
430 Stainless Steel
430 is a ferritic stainless steel commonly used for appliance panels, decorative parts, indoor equipment and cost-sensitive applications.
The required corrosion environment and forming requirements should be reviewed before material selection.
201 Stainless Steel
201 stainless steel can provide a cost-effective solution for selected decorative and indoor applications.
It should be used only after confirming that its corrosion resistance is suitable for the operating environment.
2205 Duplex Stainless Steel
2205 duplex stainless steel offers higher strength and strong resistance to chloride-related corrosion.
It is often considered for marine, chemical, structural and demanding industrial applications.
Fabrication and welding procedures should be confirmed before production.
