Rectangular-pattern perforated metal sheets are a versatile and cost-effective solution when you need to control airflow, daylight, privacy, and aesthetics at the same time. In this article I’ll explain the key factors that determine ventilation and light transmission for rectangular perforated metal sheet ventilation applications, give practical design rules, show a simple open-area calculation, and […]

Galvanized perforated metal sheets are widely used in architecture, industrial filtration, HVAC, machinery guards, and decorative façades. Their long-term performance depends not only on the base metal and hole pattern, but crucially on the adhesion of the zinc coating to the steel substrate and the sheet’s resistance to mechanical wear. This article walks through the […]

Slotted perforated metal sheets are a versatile solution used in facades, sunshades, machine guards, ventilation, acoustic panels, and decorative elements. Choosing the right material directly affects durability, appearance, maintenance needs, and long-term cost — especially when the panels are exposed to weather, salt air, or industrial pollutants. This article compares the common materials, explains how […]

When evaluating the long-term performance of 316L perforated metal panels, salt-spray resistance is one of the most critical indicators. Whether the panels are used in coastal buildings, chemical processing areas, or outdoor architectural projects exposed to high humidity, a reliable corrosion-resistance assessment ensures that the material can maintain durability, structural integrity, and visual quality. While […]

Perforated metal with round holes is a time-tested choice for architectural acoustics. This article breaks down how round-hole perforated metal acoustic panels work, what design variables most influence sound absorption, and practical guidance for choosing and installing panels in real-world projects. The goal is simple: help specifiers and buyers understand why round-hole perforated plates are […]

Micro-perforated metal panels have become a trusted solution in architectural acoustics thanks to their ability to achieve powerful sound absorption without foam, fabric, or traditional porous materials. Their performance is closely tied to how they interact with sound at different frequencies. Understanding this frequency response is essential for choosing the right panel configuration for any […]

Perforated carbon steel plates are more than just decorative panels — their hole geometry and arrangement play a major role in how air moves through them. For engineers, architects, and product specifiers, choosing the right hole pattern is a balance: you want enough open area for airflow while keeping structural integrity, acoustic behavior, and appearance […]

Cross-perforated plates (plates with cruciform or “cross” shaped punches) combine visual character with functional advantages — from acoustic panels and sunshades to safety grating and filtration. Their unusual geometry changes how stress flows through the sheet compared with simple round or square holes. This article walks through hole-pattern geometry, how stress concentrates and spreads around […]

When people think of acoustic panels they often picture soft, fabric-wrapped boards. But metal — especially aluminum — plays a surprisingly effective role in controlling noise when designed properly. An aluminum perforated acoustic panel is more than a decorative metal face: it’s a carefully engineered system that lets sound through the front skin and uses […]

Machine guards do more than keep hands and tools out of danger — when designed well they protect equipment, manage heat, and help maintain reliable airflow. Among perforation patterns, the hexagonal (honeycomb) layout strikes a rare balance of open area, structural strength, and predictable flow behavior. This article explains why hexagonal perforated metal sheets work […]
