ZEH is deeply engaged in the R&D and manufacturing of Grilles products, focusing on materials, technology, audio adaptation and practicality.

Strict Material Selection (Material Feature):Weather-resistant stainless steel is used for outdoor models, and lightweight aluminum alloy and polymer composite panels are selected for indoor and audio models, which balance high strength, corrosion resistance, acoustic compatibility, light weight and easy installation, suitable for multiple scenarios.

Precision Manufacturing Process (Technical Feature):Integrating precision manufacturing and acoustic simulation technology, CNC engraving or metal etching is adopted for core parts, with aperture error ≤ ±0.05mm. Integrated stamping forming reduces splicing, with excellent flatness and stability.

Audio Optimization (Audio Feature):Scientifically designed grille parameters, with sound transmission rate up to 98%, reducing sound wave loss, suppressing resonance noise, accurately restoring sound quality, suitable for various audio terminals, balancing protection and sound quality.

Practical and Convenient (Practical Feature):Outdoor models have IP65 waterproof and dustproof performance; indoor models support multi-directional installation. Modular design allows easy disassembly and cleaning without professional tools, suitable for audio, ventilation, architectural acoustics and other scenarios.

Anti-aging and Durable (Practical + Material Feature):The surface is treated with anodizing and anti-ultraviolet spraying, resisting exposure and humidity, with service life over 15 years, impact-resistant and wear-resistant, reducing later maintenance costs.

Flexible Customization (Technical + Practical Feature):Relying on flexible production lines, it can be customized in aperture, size, color, etc., supporting logo and special shapes, balancing functionality and decorativeness, suitable for personalized needs.

Our grilles boast customizable structures and diverse material options, supporting strip, circular, special-shaped and grid designs. With core properties of ventilation, light transmission, protection and partitioning, they are tailor-made for architecture, electronics, new energy and other industries, meeting all scenario-specific demands.

The Customizable Metal Mesh Cover &Plastic cover Applications

As a fundamental component consisting of strip-shaped, circular, special-shaped or other grid-like structures, grilles are widely applied in architecture, industry, transportation, electronics, municipal engineering, aviation, new energy and other fields by virtue of their multiple core properties—ventilation, light transmission, protection, partitioning and ornamentation. They have become key components that integrate practicality with functionality.

The structure of grilles can be flexibly tailored to scenario-specific requirements: ranging from fine metal grids to wide bar grilles, and from diverse material options to customized styling designs. This adaptability enables grilles to meet the special demands of different sectors, making them play an irreplaceable role in enhancing product performance, optimizing user experience and enriching visual effects.

Automotive Audio Field

As core components of in-vehicle audio systems, subwoofers specifically compensate for the insufficient low-frequency output of main speakers, enhancing the low-frequency richness of music and human voices during driving. Combined with the mid-to-high frequency reproduction capability of automotive audio speakers, they create an immersive in-vehicle audio experience.

Home Entertainment & Performance Fields

In home theater and living room audio systems, subwoofers can deliver powerful cinematic sound effects (such as explosions and ambient scene sounds), while mid-to-high frequency speakers reproduce human voices and details. In KTV audio systems and large-scale entertainment performance scenarios, our designed subwoofers enhance the low-frequency penetration of music, boost the appeal of the on-site atmosphere, and meet the demand for highly immersive auditory experiences.

Professional Large-Scale Equipment Integration

As core sound-generating units for products like active speakers, line array speakers, and professional monitoring equipment, large-sized speakers (including audio speakers and subwoofers) are key carriers of “sound output terminals.” Crafted from high-quality materials and featuring synchronized optimization design for deep bass and high frequencies, they ensure professional equipment delivers stable and accurate full-frequency sound in scenarios such as recording monitoring and stage sound reinforcement, meeting the strict requirements of professional audio workers.

Specialized Scenario Fields

In aviation and military simulation scenarios, professional large-sized audio speakers and subwoofers can simulate physical vibrations in real environments (such as engine roars and equipment operation vibrations) through low-frequency vibration feedback, helping to improve the authenticity of simulation training. In game room scenarios, large-sized audio speakers and subwoofers enhance the low-frequency special effects of game sounds (such as the impact of gunshots and explosions), while high-frequency speakers reproduce in-game ambient sounds and command details—further strengthening the sense of immersion in the gaming experience
