TECHNICAL DESCRIPTION OF PRODUCT
The Panacor ACX160/ALX160 noise barrier is a product specially designed to reduce the noise generated by road and rail traffic.
Its design criteria use the noise signature of road and rail traffic is a reference, subsequently adapting the barrier’s noise abatement properties to optimise its overall efficiency.
Likewise, the design seeks to optimise the panel’s mechanical performance by fitting it with two deep guiderails to improve its mechanical ability to withstand wind pressure.

THICKNESS: | 132 mm |
BARRIER COMPOSITION
The noise barrier can be made of grade DX51D+Z200/275-NA galvanised Steel plating in ccordance with standard UNE EN 10142, or with AA 3105 H24 aluminium sheet, either of which has a powder coating finish, customised as required in any shade on the RAL colour chart.
The inside of the composite panel is made up of sound-absorbing mineral wool of various densities and thickness depending on the precise noise-abatement properties required.
Thus, panels comprise four metal parts. The inner face (directed at the noise source)has holes over 36% of the surface área to provide for noise absorption, while the outer face is a plain, reflective panel. Barrier panels are installed between vertically arranged HEB/HEA profiles to achieve the desired overall height, in 300, 400 or 500 mm modules, and the distance between posts can be varied.

STRUCTURAL COMPONENTS
The barrier support structure is made up of HEA/HEB metal profiles with a welded baseplate, both grade S275JR according to standard EN 10025.Baseplates and profiles are galvanised and powder coated in accordance with the requirements of standards EN 1461 and EN 15773.
The profile posts are anchored to the foundations by means of anchor bolts of varying diameters, lengths and grades depending on the specific requirements of each individual project
BARRIER ASSEMBLY
The barrier panel is designed to be mounted without any need for rivets or bolts and thus can easily be installed manually by two people without any need for electricity.
This rivet- and bolt-free solution is highly suited to situations where fatigue problems may appear, for example in hi-speed railway construction projects
ASSEMBLY STAGES
01 The flat plate is placed on trestles. Then the mineral wool is placed on top of it, followed by the perforated metal sheet.
02 The two end guiderails then slide onto the composite sandwich.
03 This forms the finished barrier panel.
SURFACE FINISH
The thermosetting polyester powder coating process to which PANACOR ACX160/ALX160 acoustic fence panels are subjected produces excellent resistance to the effects of adverse weather, heat or continued exposure to sunlight, by providing enhanced corrosion-resistance and thus a product that requires practically no maintenance.
STAGE 1
PRE-TREATMENT
Automatic process to prepare panels for electrostatic application of paint powder.Dip 1
Tank capacity: 5600 lDip temperature: 35 to 45ºC
Composition of dip liquid: De-greasing agent; passivator; water;
Daily monitoring of concentration levels in pre-treatment dip tank 1 according to specific procedure.
Dip 2
Tank capacity: 2300 lDip temperature: room temp.
Composition of dip liquid: water
Dip 3
Tank capacity: 2300 lDip temperature: room temp.

STAGE 2
DRYING
All metal parts are placed in a blow drying tunnel at a temperature of between 80 and 100ºC to eliminate any moisture prior to the subsequent spray coating stage.
STAGE 3
PAINT BOOTH
Automatic process using robots and touch-up guns with spray nozzles that guarantee a perfectly smooth, uniform coat is applied to the panels to ensure an excellent finish.
STAGE 4
POLYMERIZING OVEN
Process in which the paint finish is achieved by applying heat for at least 10 minutes at an average temperature of 200 ºC Oven temperature: 165 to 230ºC.
