Micro Expanded Metal - Economical Choice for Filtration

Micro expanded metal, a light gauge of metal with small openings, can be considered a particular type of expanded metal. Different from perforated plates, micro expanded metal is produced by cold metal cutting&stretching machines to create uniform openings and gaps in different styles and sizes, without punching waste material. Its tide and even holes permit air, liquid, and light transfer easily, and its one-piece construction makes the metal itself strong and durable to give excellent support during filtration.
With a professional design and technical department, we can produce and supply customized micro expanded metal to best-fit clients’ requirements. And if you can’t find what is the most suitable type for your project, welcome to email us directly, then we will give you our professional suggestions.
