To be a valuable global supplier
for metallic honeycombs and turbine parts
Square metal substrates are widely used in industrial emission control systems because of their simple, practical design and durability. You’ll find them in power plants, automotive exhaust systems, and chemical plant flue gas treatment setups, where stable performance is essential.
In power plants, square metal substrates are commonly used in catalytic converters or oxidizers to manage large volumes of exhaust gas. Their shape makes stacking straightforward and ensures the catalytic coating gets good coverage. Gas flows evenly through the substrate, which improves efficiency and keeps pressure drops low. Many operators prefer square substrates because they are easier to handle during installation and maintenance, especially in big systems.
In heavy-duty trucks and off-road vehicles, square metal substrates are sometimes used in DOC (Diesel Oxidation Catalyst) units. The square shape fits larger housings better and allows for modular replacements when needed. Mechanics often point out that these substrates hold up well under repeated heating and cooling cycles, which helps meet emission standards reliably.
Chemical plants also rely on square metal substrate for flue gas treatment. Their geometry helps distribute gas evenly across the catalytic surface, which improves pollutant conversion and reduces hotspots. The rigid square structure also resists vibration and makes it easier to fit into existing ductwork, which is important in busy industrial environments.
Overall, the square metal substrate combines sturdiness, efficient use of surface area, and ease of handling. Regular cleaning and inspections are still needed to keep them performing well, but their reliability and practical design make them a favorite in many industries.
In short, whether it’s power generation, automotive exhaust, or chemical processing, the square metal substrate delivers consistent, durable, and easy-to-maintain solutions for emission control.
