Foshan Shengfeng Building Materials Co., Ltd., a leading manufacturer of aluminum architectural products, has introduced a newly developed perforated aluminum square tube series designed to significantly improve acoustic control in high-traffic public environments such as subway stations, airport terminals, railway hubs, and convention centers.

With growing global demand for both aesthetic ceiling solutions and effective noise reduction in large‑span spaces, Shengfeng’s engineering team optimized the perforation pattern, hole diameter, and backing layer configuration of its aluminum square tubes. The new design achieves an NRC (Noise Reduction Coefficient) of up to 0.75, effectively absorbing mid‑to‑high frequency noise generated by passenger flow, public announcements, and mechanical systems.

"Our upgraded perforated aluminum square tubes combine structural strength with acoustic performance, making them ideal for transportation hubs where comfort and clarity are critical," said a product manager at Shengfeng. "Unlike traditional non‑perforated ceilings, our solution reduces echo and reverberation without compromising the modern, clean look architects desire."

The new product line retains all advantages of standard aluminum square tubes – lightweight, corrosion‑resistant, fire‑rated, and easy to install – while adding a functional acoustic layer. Multiple perforation patterns are available, including circular, square, and slotted holes, with custom hole sizes and arrangements to meet specific project requirements. The tubes are manufactured using the company’s advanced CNC punching equipment and finished with its in‑house electrostatic spraying line, offering over 200 RAL colors and a durable, easy‑to‑clean surface.

Shengfeng has already supplied the new acoustic square tubes to several infrastructure projects across China and Southeast Asia, including a newly expanded terminal at a regional airport and three underground metro stations. Early feedback from contractors and acoustic consultants has been highly positive, citing improved speech intelligibility and reduced passenger fatigue.

As part of the company’s commitment to quality and innovation, all perforated aluminum square tubes undergo strict testing in compliance with ISO and CE standards. The products are backed by Shengfeng’s 10,000㎡ Foshan base and 20,000㎡ Chengdu base, with a combined annual production capacity supporting thousands of projects worldwide.
