Body and structural members
Longitudinal rails, cross-members, roof supports, subframes, side structures, brackets, and lightweight frame assemblies.
Application pathway
Automobile Industry
Lightweight structural, crash-management, battery, trim, and thermal profile concepts for vehicle manufacturing.
Application guide
Where the profiles are used.
Automotive extrusions can form lightweight structural members, crash-management components, battery and electronics housings, roof and body rails, steps, trim carriers, and thermal-management parts. The section is developed as one element of a complete vehicle system, with geometry coordinated around loads, joining, corrosion protection, manufacturing rate, assembly sequence, and repair strategy.
Crash-management systems
Bumper beams, crush cans, reinforcement sections, and controlled-deformation members designed by the vehicle engineering team.
Battery and electric-vehicle systems
Battery-tray rails, enclosure frames, sealing lands, cooling interfaces, cable routes, inverter housings, and protective members.
Trim, access, and thermal parts
Running boards, roof rails, door or window members, seat tracks, heat sinks, motor housings, and visible trim sections.

Assembly mechanics
How the assembly works.
These principles explain the role of the extrusion inside the finished assembly. Final dimensions and performance must be checked against the project design and selected hardware.
Principle 01
The section carries distributed loads
Outer walls, internal webs, hollows, and attachment flanges create bending, torsional, bearing, and local stiffness along the vehicle structure.
Principle 02
Joints transfer load between systems
Welds, bolts, rivets, adhesives, inserts, cast nodes, and formed end features connect the extrusion to sheet, cast, or composite components.
Principle 03
Some members manage impact energy
Vehicle engineers tune geometry, alloy, temper, trigger features, joints, and deformation space so selected components collapse in a controlled manner.
Principle 04
Production turns length into assemblies
Sawing, machining, bending, forming, joining, coating, inspection, and sequenced delivery convert long profiles into repeatable vehicle parts.
Alloy guidance
Alloy requirement for technical review.
The final alloy and temper are confirmed against the controlled drawing, required strength, extrusion geometry, fabrication route, finish, and service environment.
Alloy status
To be confirmed against the drawing
Availability, temper, tolerances, and suitability are confirmed during technical review.
Engineering fit
Match the challenge to the profile strategy.
Common requirements
What the application must account for
- Mass reduction
- Crash and fatigue load paths
- High-volume repeatability
Profile response
How aluminium profiles can help
- Multi-function cross-sections
- Fabrication-aware design
- Consistent repeat supply
Technical decision points
Information that drives profile selection.
Structural and crash targets
Define load paths, stiffness, energy-management intent, deformation envelope, fatigue duty, and vehicle-level validation responsibilities.
Packaging space
The section must fit body, battery, suspension, glazing, trim, service, and occupant-clearance zones while preserving tool access.
Joining strategy
Material stack, weldability, adhesive gaps, rivet or bolt access, inserts, heat input, distortion, and corrosion isolation require early coordination.
Manufacturing rate
Cycle time, datum scheme, automated handling, machining fixtures, poke-yoke features, inspection frequency, and line-side presentation affect geometry.
Corrosion and finish
Road salts, trapped moisture, dissimilar metals, drainage, sealants, coatings, visible surfaces, and stone-impact exposure should be reviewed.
Service and repair
Fastener access, replacement boundaries, joining method, crash repair approach, drainage, and protection influence the final component design.
Practical technical facts
Extrusions combine structure and interface
One profile can carry load while also providing mounting flanges, sealing lands, cable channels, locating features, and finished edges.
Vehicle performance is system-level
Crash, fatigue, stiffness, sealing, and durability depend on the complete joined assembly rather than the isolated profile.
Electric vehicles expand thermal needs
Battery, power-electronics, inverter, and motor systems create opportunities for structural housings and heat-transfer profiles.
High volume rewards stable datums
Clear locating faces and tolerance strategy improve machining, gauging, automated assembly, and repeat supply.
