Noise barriers supplied by Vinh Hung IP, which meet all current standards, are able to minimize the noise affecting surrounding area (residentialareas, hospitals, schools, industrial parks, etc.)
and ensure a fine landscape. The noise barriers are windproof and aid to driver's concentration which could increase safety for people and other vehicles.
PRODUCT CHARACTERISTICS
Absorptive noise barrier:
Using sound-absorbing materials, punch plates,
etc., which prevent sound reflection.
Sound absorption standard rating: Noise Reduction
Coefficient NRC describes the average sound
absorption performance of noise barrier.
For the absorptive noise barrier, the NRC will be
within 0.6 to 0.9 range (FHWA highway noise barrier
design handbook).
Reflective noise barrier:
Using good noise insulation materials such as
Polycarbonate panels (PC), Poly methyl methacrylate
panels (PMMA), Glass laminate.
Sound reflective standards: Transmission loss
coefficient TL will measure the amount of sound energy
hitting on or transmitted through the barrier.
For the reflective noise barrier, the TL coefficient is
>25 dB at 500HZ and >30 dB at 1000HZ (according to KS
F4770 standard).
INSTALLATION
Preparation:
Prepare installation materials, tools and equipment.
Check the surface of base structure:
- Check the distance among the anchor bolts.
- Check the dimensions of posts flanges, positions of bolt holes and anchor bolts.

Traffic control barrier gate, parking lot barrier provies a rapid, reliable and smooth operational way with low power consumption Traffic control barrier gate JDDZ-11 is an efficinet vehicle access control solution for controlling entry of authorized resident vehicles at safe pre-determined time intervals, coming with compact and stylish design for restrict areas with high traffic flow. The combination of the advanced digital DC24V brushless motor and a planetary gearing system with sinusoidal movement for a soft start and soft stop action, ensures a smooth elevation or lowering of the barrier arm, and avoiding bounce in the end position. On the other hand, automatic vehicle barrier gate JDDZ-11 provides variable speed 0.6~ 6 seconds for different boom length. In general, each boom length Is set to a standard operational speed but can be simply adjusted directly from control board to get a faster or slower speeds depending on the requirement. Designed for both indoor and outdoor application, providing a rapid, reliable and smooth operational way with low noise and low power consumption, and flexibly integration various access control systems, traffic control barrier gate JDDZ-11 is generally used in commercial and industrial applications such as controlling access to parking lots and garages in large business complexes, airports and public facilities. Traffic Control Barrier Gate Featurers 1. Speed 0.6 second up to 6 seconds depending on the settings 2. Energy saving DC24V brushless motor gearbox 3. Manual operation in the event of power failure 4. Smooth and efficient operation 5. Secure operation with safety devices 6. Possibility of integration with any type of access control systems 7.
