Architectural metal parts
The correct production route depends on the stainless steel grade, sheet thickness, part geometry, quantity, surface requirement and dimensional tolerance.
Stainless Steel Cutting Services
Laser Cutting
Laser cutting is suitable for producing customized profiles, holes, slots and complex shapes from stainless steel sheet.
It is commonly used for:
Brackets
Flat blanks
Equipment panels
Ventilation patterns
Mounting plates
Decorative components
Enclosure parts
Prototype components
Repeated production parts
Before production, the drawing should clearly identify:
Finished part dimensions
Hole diameters
Slot dimensions
Internal and external contours
Critical tolerances
Visible surface
Protective film requirements
Quantity
Very small holes, narrow slots and closely spaced features should be reviewed in relation to the sheet thickness and production method.
Shearing and Cut-to-Size Production
Shearing is commonly used for straight cuts and rectangular blanks.
It can be suitable when buyers require:
Rectangular panels
Cabinet blanks
Wall panels
Simple covers
Standard strips
Straight-edge components
Material prepared for later bending
Shearing requirements should specify the finished width, length, squareness and edge condition.
Punching and Drilling
Punching or drilling may be used for:
Mounting holes
Ventilation holes
Fastener positions
Repeated hole patterns
Access openings
Assembly features
Hole diameter, spacing and distance from bends or edges should be reviewed before production.
Deburring and Edge Finishing
Cut stainless steel parts may require deburring or edge finishing according to their final use.
Available requirements may include:
Removal of sharp edges
Light edge breaking
Burr reduction
Edge polishing
Preparation for welding
Preparation for assembly
The required edge condition should be stated on the drawing or purchase specification.
Stainless Steel Bending Services
Press Brake Bending
Press brake bending is used to form flat stainless steel blanks into angular components.
Typical products include:
L-shaped brackets
U-shaped channels
Z-shaped profiles
Trays
Covers
Cabinets
Enclosure panels
Frames
Architectural trims
Machine components
The bending result depends on:
Material grade
Sheet thickness
Bend radius
Bend angle
Flange length
Bend direction
Tooling
Grain direction
Springback
Number and sequence of bends
Bend Radius
The inside bend radius should be specified wherever it is functionally or visually important.
An extremely small bend radius may increase the risk of:
Surface marking
Material cracking
Distortion
Dimensional instability
Tooling interference
The required radius should be reviewed against the material grade, thickness and bending direction.
Bend Direction
For brushed, hairline or otherwise directional surfaces, drawings must identify the visible side and grain direction after bending.
The grain direction on the flat blank may not match the desired visual direction on the finished component unless it is planned before cutting.
Springback
Stainless steel can recover slightly after the bending force is removed.
This effect is known as springback.
The amount of springback depends on the stainless steel grade, thickness, bend radius, tool selection and forming method. Bend angles should therefore be confirmed through the agreed production process rather than assumed from the flat drawing alone.
