Aluminium Flat
What is Aluminium Flat?
Aluminium Flat is a rectangular, solid strip of aluminium used in structural, decorative, and fabrication applications. It offers excellent corrosion resistance, strength-to-weight ratio, and formability. Aluminium flats are widely used in brackets, trims, construction supports, frames, and more.
Asiad Steel Industries manufactures and supplies premium-grade Aluminium Flats in a wide variety of sizes and alloys, ensuring accuracy, consistency, and superior finish.
