As a premier supplier of high-end acoustic systems serving Brazil, Shandong Qianbang New Building Materials Co., Ltd. delivers state-of-the-art AKU panels engineered specifically to tackle the acoustic demands of high-density metropolitan spaces in São Paulo. From the busy corporate towers along Avenida Paulista to the creative hubs in Pinheiros, our sustainable, PET-felt-backed wood slatted panels provide structural resilience and acoustic relief with an NRC rating of up to 0.85.
São Paulo stands as the financial engine of Latin America, hosting a massive matrix of commercial office high-rises, mixed-use complexes, and dense urban developments. However, this high concentration of commercial activity brings the challenge of environmental noise pollution. Brazilian municipal and national building codes, including ABNT NBR 10152 (which specifies acceptable noise levels for internal environments), impose strict regulatory thresholds for sound levels in public places, offices, and educational centers.
Architects and mechanical designers in districts like Faria Lima, Vila Olímpia, and Berrini are increasingly using AKU acoustic slatted panel systems to handle these acoustic challenges. Our premium PET-backed wood acoustic panels act as highly efficient sound absorption units, designed to control mid-to-high frequency reverberation, reduce background noise levels, and improve speech intelligibility in open-plan corporate work environments.
Acoustic comfort is not just about blocking sound; it is about managing sound energy through precise material layering.
Our panels feature a 9mm dense polyethylene terephthalate (PET) felt backing created from recycled post-consumer plastics. It acts as an open-porous structure that traps and dissipates high-frequency noise waves, turning kinetic sound energy into thermal energy.
Each wood MDF slat is spaced precisely (typically 13mm to 15mm gaps) to allow sound waves to pass freely into the PET backing while diffusing ambient reflection. Available in wood veneer, bamboo charcoal, or scratch-resistant laminates.
Engineered to meet international Class B1 fire resistance ratings and low VOC emission profiles. Our production lines eliminate added formaldehyde, making the panels safe for classrooms, medical facilities, and government spaces.
Shandong Qianbang New Building Materials Co., Ltd. is based in Linyi, Shandong Province, the wood and logistics capital of China. Our factory operates over ten production lines equipped with automated CNC machinery that handles precise wood slitting, milling, veneer laminating, and assembly. By integrating raw material processing and shipping under one roof, we reduce intermediate production steps and maintain strict quality standards.
Our supply chain resilience is built on strong long-term relationships with major raw material producers, guaranteeing a steady supply of FSC-certified timber, bamboo charcoal cores, and PET backing sheets. This structural advantage allows us to offer competitive, direct-from-factory pricing while ensuring stable lead times even during global freight capacity fluctuations.
We optimize logistics for our South American clients, particularly in São Paulo. We coordinate with shipping lines from the Port of Qingdao to the Port of Santos, handling container planning, moisture-barrier packaging, and necessary commercial paperwork to ensure clean customs clearance.
