EXPANDED METAL INFILL PANELS FOR SECURITY, DECORATION AND DURABILITY
Expanded metal panels are made from a single piece of metal through slitting and stretching process. Finished products without any welding or waste of materials and offer a clear and bright visual effect. Based on the above characteristics, expanded metal panel are ideally used as the infill panels for balustrade & railing. They are multipurpose for bridge, terrace, balcony, stairs and so on. Our products are all treated with anticorrosive coating to ensure durability both outdoors and indoors.
- Good ventilation, allow flow of air & light.
- High strength and rigidity for security.
- Anti-corrosion surface treatment for durability.
- Various patterns, finishes & innovative colors.
- All-purpose for both indoor and outdoor applications.
- Easy to install and maintenance free.
Expanded Metal Bridge with High Bearing Capacity, Anti-Skid, Beautiful
Expanded metal is often used as walkways, platforms, handrails and stair treads on the bridge. Expanded metal grating with high bearing capacity, coupled with good anti-skid performance, it is very suitable for pedestrians walking. Expanded metal grating with small-sized openings are especially suitable for women in high heels to prevent heels from falling. In addition, the use of bridge handrails made of expanded metal, from afar to give a person a kind of transparent and lightsome feeling, will not like the bridges made of other materials as people feel very cumbersome.
- Features of expanded metal on the bridge
- High strength and high bearing capacity.
- High security with anti-skid.
- Simple and beautiful appearance.
- Saving costs.
- Durable with longer lifespan.
Applications of expanded metal on the bridge
Expanded metal on the bridge can be used as:
• Platforms.
• Walkways.
• Handrails.
• Stair treads.
Noise Barrier / Sound Attenuation / Acoustic Board
In downtown area and heavy traffic area, the noise troubles civilians long term. There are several noise barrier products at the markets, such as perforated metal or louver type noise barriers. But they all need the extra sound absorbing materials to achieve the needed effects and some of the sound absorbing material is not environmentally friendly.
As we all know the sound resistance of surface material is inversely proportional to the open area. Thinner opening, better sound resistance. So, we recommend the micro expanded metal as the noise barrier.
Working Principle
The noise barrier is evenly distributed with raised pyramid and oval tiny holes. When the noise contact with the surface of noise barrier, most of the noise are reflected and attenuated by the raised pyramid. And the rest noise/sound are penetrated through numerous tiny holes and long passing distance. At last, most of the noise/sound are reduced. Thus, it can achieve better noise reduction and sound absorption performance and it is more environmentally friendly.
