The galvanized carbon steel base provides high structural strength, with a polyester coating that effectively isolates the steel surface from corrosive industrial gases and liquids, extending the service life to over 5 years. The hexagonal hole design increases the filtration area by 15% compared to round holes, improving filtration efficiency up to 90% for particulate matter with a diameter of ≥10μm. The 1.5mm sheet thickness ensures resistance to deformation under high-velocity exhaust airflow, maintaining stable filtration performance during continuous operation. It can withstand acid-base environments with a PH range of 4-10, suitable for chemical and metallurgical industries with corrosive exhaust gases. The product is pre-cut to standard sizes compatible with most industrial dust removal frames, reducing on-site processing time and installation labor costs. Compared to stainless steel perforated sheets, it offers a cost-effective solution while maintaining reliable performance, helping enterprises reduce environmental protection investment costs.
Standard sheet dimensions are 1220mm×2440mm, with custom sizes available upon request. The base material is galvanized carbon steel with a zinc coating thickness of 80μm, and the surface is covered with a 50μm thick polyester coating to enhance corrosion resistance. The hole type is hexagonal, with an inscribed circle diameter of 8mm and a hole pitch of 10mm, resulting in an opening rate of 40% to balance filtration efficiency and structural stability. The sheet thickness is 1.5mm, with optional thicknesses of 1.2mm and 2.0mm to meet different airflow pressure requirements. Filtration efficiency reaches 90% for particulate matter ≥10μm, meeting national industrial emission standards. The operating temperature range is -10℃ to 120℃, ensuring stable performance in high-temperature exhaust environments. Tensile strength is ≥350MPa, and it passes ISO14001 environmental management system certification and GB/T13912-2002 galvanizing standards.
Ideal for dust removal systems in cement plants, steel mills, and thermal power plants, where it filters large particulate matter from flue gas to reduce air pollution. In chemical factories, it is used to filter corrosive exhaust gases containing acid or alkaline particles, protecting downstream purification equipment. It is also suitable for wood processing plants to filter sawdust and dust, reducing the risk of dust explosions and improving workshop air quality. In metal processing industries, it filters welding fumes and grinding dust to protect workers' health. The frame-mounted installation system allows for quick replacement during maintenance, minimizing production downtime. Additionally, it can be used in industrial ventilation systems to filter incoming air, preventing dust from entering production workshops and protecting precision equipment from contamination. Its cost-effective design makes it a preferred choice for small and medium-sized enterprises with limited environmental protection budgets.
