Rain-proof shutter is a kind of shutter structure used to prevent wind and rain intrusion, it is composed of a plurality of shutter pieces, can effectively block wind and rain, protect the indoor safety and indoor environment.
NCC louvers can be made into sound-absorbing louvers with single or double leaf structures, with a minimum structural height of 850mm. The standard height for single leaf doors is 1250mm x 3000mm, and the height for double leaf doors is 2500mm x 3000mm
All doors are equipped with joint locks, latches, and handles
Soundproof doors can be provided with bird guards and insect nets upon request
The door can be provided with polyester powder coating
Can be made of galvanized steel, stainless steel, or aluminum
The main features and benefits of NCC acoustic louvers are:
Equipped with weatherproof sealing plate to prevent rain and snow infiltration.Equipped with rainproof and rust-proof material selection and
surface treatment process.
Reduce reflection noise and parallel barriers to improve indoor sound insulation.
Louver ventilation improves indoor air quality.The modular design makes the louvers suitable for "vents" of any size.
It can be used as an independent barrier around the equipment or combined with building walls.Composed of prefabricated parts, it can be assembled in the field quickly and without welding.
The horizontal layout of the sand shutter not only reflects the beauty, but also enhances the sand and dust prevention performance.Effectively prevent sand and dust from entering the room and adjust the indoor temperature and humidity.
With steel structure design ability, with wind, snow load calculation ability, improve indoor safety.Meet anti-theft requirements and standards.
NCC's anechoic louver has an energy-efficient aerodynamic design and a very low pressure drop characteristic. The sturdy all metal structure ensures a long service life for NCC's noise reduction louvers. If necessary, we can also provide necessary supporting steel structures and provide comprehensive installation services.And for each individual project, it can be adjusted according to site conditions, as well as environmental factors.

The double row shutters FYL155S series are rated A for high rainwater permeability and are rated 2 for airflow rate and airflow class.
Single row blinds FYL100S, series with good airflow rate and airflow grade of 2.
NCC rain blinds all have Chinese GB test reports. Free area calculations can be provided based on the size of the shutter segment for each item.
NCC Acoustic Laboratory - A Laboratory Professionaly Committed to Serving Customers
We exert every ounce of our strength to construct a high-end, avant-garde laboratory endowed with autonomous control capabilities. For all bespoke products, be it in terms of specifications, dimensions, or acoustic requisites, prior to entering the mass production phase, we shall enforce rigorous and meticulous pre-production sample testing procedures. Only upon thorough confirmation that all indicators are up to par will we invest a considerable amount of human and material resources to embark on mass production endeavors, thereby effectively guaranteeing that each and every batch of large-scale goods delivered to clients possesses outstanding quality.
The fabricated product samples are positioned within the spacious window of the laboratory and securely fastened through professional sealing measures. Through precise adjustment of the relevant parameters and concurrent utilization of advanced and precise apparatuses for comprehensive and profound testing, it is ultimately ensured that the products can fully comply with the exacting requirements of customers.
As depicted in the illustration, the external noise of the laboratory attains 80.1 dB, while through random measurement, the internal acoustic laboratory drops to 36.4 dB or even lower. The elevated standard of sound insulation not only ensures the accuracy of the experimentation but also furnishes a robust guarantee for the test outcomes.
