Road Signs Aluminum Circle Disc

Our Road Signs Aluminum Circle Disc is precision round aluminum blank specially produced for traffic signage fabrication, also widely applicable for deep drawing, spinning and stamping processing. Available in 1060, 3003 and 5052 aluminum alloys, the Road Signs Aluminum Circle Disc balances outstanding shaping performance, structural strength and smooth surface, perfectly matching mass production demands of road signs and various industrial products.

The Road Signs Aluminum Circle Disc covers diameters from 100mm to 1200mm and thickness ranging 0.3mm–6.0mm, flexible enough for small trial orders and automated large-volume production. Manufactured with DDQ deep drawing grade aluminum raw material, the Road Signs Aluminum Circle Disc features Erichsen cupping value of 9–12mm, which avoids cracking and surface flaws during deep forming.

Strict precision cutting keeps diameter tolerance ±0.5mm and thickness tolerance ±0.03mm, ensuring the Road Signs Aluminum Circle Disc fits stamping machines and processing fixtures precisely. All edges are fully deburred without burrs for direct safe usage without secondary trimming. Kraft interleaving paper is laid between layers to guard the Road Signs Aluminum Circle Disc against scratches during storage and ocean transportation.

Multiple tempers including O, H14, H24, H26 and H112 are optional. H14 & H24 temper are the most popular picks for the Road Signs Aluminum Circle Disc, delivering proper rigidity, weather resistance and flatness ideal for outdoor traffic sign panels.
