DOSSIER 01 FLAGSHIP SUPPLY PROGRAMME

02 BYD · DOUBLE-DECK BUS PLATFORM

Take weight out across
both roof levels.

Series supply of upper roof and intermediate roof structures, engineered around the combined demands of mass, insulation, equipment interfaces and double-deck body integration.

PROGRAMME SCOPETWO-LEVEL
SERIES SUPPLY

Starting requirement: Resolve both roof levels as vehicle systems rather than separate stacks of structural and insulation parts.
AEVISS supply scope: Vehicle-specific sandwich composite upper roof and intermediate roof structures for double-deck bus programmes.
Engineering response: Coordinate mass, thermal layers, equipment zones, adjacent interfaces and assembly needs across both supplied levels.
Commercial significance: A sustained customer relationship documented across company market, delivery and service records.

WHY IT MATTERSThe programme demonstrates how one supply responsibility can coordinate lightweight structure and integration across two levels of a double-deck vehicle.

03 YUTONG · VEHICLE-SPECIFIC PROGRAMME

Fit the roof
to the platform.

The structure follows the vehicle definition: geometry, interfaces, insulation duty, assembly conditions and customer acceptance requirements.

DOSSIER 02 CUSTOM COMPOSITE ROOF ENGINEERING CUSTOMER / YUTONG

01 / CONTEXT

Bus-platform application

Roof requirements vary with body architecture, installed equipment and operating conditions.

02 / SUPPLY

Lightweight composite roof structure

AEVISS customer records document roof supply and programme-specific product development.

03 / RESPONSE

Configuration around the vehicle

Structural zones, interfaces and production definition are coordinated around the target platform.

04 / RESPONSIBILITY

Engineering through delivery

Differentiated service and programme support connect the supplied product to vehicle delivery needs.

04 SURBODY · DEVELOPMENT PROGRAMME

Extend lightweight engineering
across the body.

The SURBODY single-deck development programme combines composite roof, side, platform and floor thinking within a multi-material vehicle-body architecture.

DEVELOPMENT PURPOSE Move from optimising isolated parts to coordinating mass, structure, joining and assembly across the complete body system.

05 SUPPLY EVIDENCE
