Refer to attached drawings
The RB8 bus is built with an integrated body
shell structure that is safe, strong and as light as
reasonably possible. It utilises High Tensile
Galvanised steel tubing in combination with
rolled and pressed sections to produce a vehicle
of exceptional strength and durability. All hollow
sections are injected with a corrosion protection
coating to inhibit rust formation inside the
structure. The body structure is ADR compliant.
All exterior panels are made of GRP (fiberglass)
including boot lid and side access doors and
hatches. The roof panel is a one piece
fiberglass sheet with extruded aluminium cant
incorporating gutter recesses on both sides from
front to rear.
The interior is clean and uncluttered. The interior
side walls and ceiling panels are Laminex. Pillar
and sill cappings are thermoformed from highly
durable ASA. Front and rear header panels, and
door pillar cappings are GRP mouldings with a
durable finish. Modesty panels are fitted in front
of the first row of seats trimmed in fabric
matched to the seat trim.
Curved one piece screen designed to maximise
driver visibility. Glass thickness is 7mm
laminated and produced to European ECE
Saloon windows are made of anti-sun tinted,
toughened safety glass, bonded to the body.
