Metalic Noise Barriers Panacor AC10

 

NOISE BARRIER PANACOR AC10

 

TECHNICAL DESCRIPTION

OF PRODUCT

The PANACOR AC10 noise barrier panel is specially designed to reduce noise generated by road and rail traffic.

Its design criteria take the noise signature of road and rail traffic as the reference on which to base the panel’s efficient noise abatement performance.

Likewise, the panel’s mechanical behaviour has also been optimised by fitting it with 4 deep intersecting joints that improve its mechanical resistance to strong winds.

COMPOSITION

OF THE FENCING PANEL

The panel is made of 1.0 mm thick steel plate galvanised to grade DX51D+Z275-NA as per standard UNE EN 10142 and heat coated to any colour on the RAL colour chart to customer’s choice.

The inside of the sandwich panel is made of sound-absorbing material based on a 50 mm thick layer of rock wool with a density of 55 kg/m3.

Fencing panels comprise two metal parts: the inner side (the one that faces the noise source) has perforated holes over 36% of its surface area to absorb noise, while the outer side is a plain, flat (reflective) surface. The panels are fitted between HEB/HEA vertical posts up to the desired height in steps of 500 mm, while the distance between posts is variable.

ACOUSTIC AND MECHANICAL

CHARACTERISTICS

STRUCTURAL

COMPONENTS

The support structure for the fence is made up of HEA/HEB metal posts on a welded base plate, both complying with grade S275JR according to standard EN 10025. Posts and base plates are galvanised and heat spray coated to meet the requirements of standards EN 1461 and EN 15773.

Posts are anchored to the foundations using anchor rods that vary in diameter, length and grade depending on the specific requirements of each individual project.

TWO-COMPONENT RUBBER
SEALS
FOR IMPROVED PERFORMANCE

The acoustic panel is designed so that it can house optional rubber seals made of one rigid PVC part and a second part made of flexible EPDM rubber, so that the panel fits the size of the different types of sections used. These seals prevent the fence panels from vibrating due to wind pressure or suction forces caused when trains and vehicles rush past. They also help to prevent any noise leaks in the contact between the panel and the support post.

SURFACE

FINISHES

Anti-corrosion treatment. The heat spray coating process to which PANACOR AC10 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 dust.

Dip 1

Tank capacity: 5600 lt

Dip 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 lt

Dip temperature: room temp.

Composition of dip liquid: water

Dip 3

Tank capacity: 2300 lt

Dip temperature: room temp

Composition of dip liquid: water

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

CURING 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.
