Back panel: HGI-1.6T

Sound absorbing material: Polyester, glass wool

Combination Installation optional with sound insulation, perforated, transparent type

3. Uneven steel type, N.B.

This technology uses noise characteristics (transmission, reflection, refraction, diffraction, etc.) to improve noise reduction performance.  The outer shape of the soundproof panel is bent in a concave shape, so effectively blocked reflections and diffracted sounds, As a plurality of air layers are formed in the portion to repeat transmission and reflection, noise reduction effect is increased. In addition, the sound absorbing material is made of polyester which is harmless to the human body in order to prevent environmental pollution.

Specifications

Front panel: AL-1.0T / GI-0.6T

Back plate: HGI-1.6T

Sound absorbing material: Polyester, glass wool

Perforated type is available to install

4. Uneven steel type, Sound insulation N.B.

It is a product developed as a substitute for extruded concrete sound insulation panel. Both sides have a very good effect of blocking the sound.

Because it is a closed type product, performance can be maintained for a long time. Powder coating makes it possible to apply the desired color and choose it to match the surrounding environment.

Combination Installation optional with sound insulation, perforated, transparent type

5. Transparent Type, N.B.

Resolve reluctance from existing metal products and does not interfere with the surrounding landscape. It is easy to create a free environment. Soundproof aluminum frame has transparent sound proof materials of glass, PC, PMMA etc to secure visibility distance and excellence of transparency

Recently, there is a tendency to use a lot of laminated glass, which was no yellowing

Combination Installation optional with sound insulation, perforated, transparent type

6. Semicircular transparent type, N.B

Unlike ordinary transparent panel, the product is designed as a semi-circular aluminum frame with transparent soundproof glass, PC, PMMA, etc., possible to secure view rights, sunshine due to excellent transparency and visibility

Frame: AL Aluminum (A6063-T5)

Soundproof material: glass, PC, PMMA

Combination Installation optional with sound insulation, perforated, transparent type

7. Semi-circular maintenance transparent type, NB

Superior Sound Insulation Performance of Transparent Soundproof Plate and maintenance of Partial Damage while Utilizing Transparency is easy and cost-effective. There is an effect that the landscape looks smooth with various colors after installation.

Application for design registration (2015-0006805)

Patent application for maintenance sound insulation panel (2015-0034789)

Perforated type is available to install

8. High-speed railway N.B  

High-speed railway products front side is made of aluminum at good absorbing effect, suppression of rust due to iron oxide powder from the rail is excellent, and it alleviates high-frequency noise emitted in high-speed railway sections.

Combination Installation optional with sound insulation, perforated, transparent type

9. Both-sided maintenance transparent type, NB

To support the transparency plate firmly even under wind pressure, Improved bearing capacity and durability of frame.

It is easy to assemble the soundproof panel and improves the construction work speed. In case of the breakage of the transparent plate, the two separate frames are used. Glass can be replaced on both sides of the soundproof plate. In addition, if the space behind the sound barrier is available, maintenance is possible without lane blocking.

Combination Installation optional with sound insulation, perforated, transparent type

10. Maintenance transparent type, NB

It is easy to assemble the soundproof plate so that the construction work can be processed quickly.

When one side separable frame is used in case of transparent plate breakage, it is possible to replace glass on the basis of one soundproof wall, which reduces maintenance cost.

Combination Installation optional with sound insulation, perforated, transparent type

11. Wood type, N.B.

Provides aesthetic effect to reduce road noise and green environment. It has excellent sound absorption and acoustic transmission loss and uses environmentally friendly wood. Excellent durability due to wood ACQ pressure preservation treatment.

Front platel: Semicircular wood (50 ~ 60Ø)

Back plate: Anticorrosive material (20,30mm)

Sound absorbing material: Polyester, glass wool

12. Soundproof Tunnel

Sound insulation effect is raised by blocking direct sound generated from noise source, Satisfactory sound insulation by blocking negative image quality in low-level areas. Minimizing the obstacles to landscaping and securing structural stability by reducing height. It is safe tunnels to reduce explosion sound at the rear of a high-speed railway tunnel and to prepare for the collapse of tunnel exit.

13. Temporary N.B (STEEL FENCE)

It is suitable for construction site and civil engineering field and protection the debris from the use of the equipment and various noise generated in construction site. It does not require any foundation work and is inexpensive and easy to install. It can be re-installed at other sites after demolition.

14. H-BEAM Post

It is one of among the important products that serve as pillars to install soundproofing. It prevents the corrosion and rust of iron through hot dip galvanizing and powder coating, and plays a role of effectively adding the durability of the soundproofing panel

15. 2W Guard rail  

It consists of Steel Circular Supports, Support Ribs, Impact Absorbing Buffer Brackets, Connection / Mounting Bolts, 2W-Beam. and 2W G/R maintains sufficient strength at the time of vehicle movement, absorbs the impact force of the vehicle by a certain amount of deformation, and improves the safety of passengers. The combination of materials is bolted to facilitate maintenance.

16. 3W Guard rail

It has the same characteristics as 2WAY and has more stability, strength and widely used.

Both 2WAY and 3WAY are used for the roadside (one side protection) or the median (for center line protection). 3WAY G/R is also bolted type and easy to maintain.
