Aluminum profiles for air ducts and air conditioners are mainly made of aluminum alloy and are used for constructing ventilation ducts and components of air conditioning equipment. They have the advantages of being lightweight, high in strength and corrosion-resistant. They are easy to be processed and formed, and can meet complex design requirements, effectively improving the performance and efficiency of ventilation and air conditioning systems. Meanwhile, they also have good heat dissipation and fireproof properties and are widely used in ventilation and air conditioning projects of various buildings.
