Aluminum Sign Blanks

Sign blanks are flat aluminium plate cut and finished for sign making — the substrate that sign shops print, laminate and mount. In this catalogue they are a documented plate product: the full-range site's plate family lists hot rolling plate, circle plate, moulding plate, sign blanks plate, brazing sheet plate, stucco plate, tread plate, mirror plate, oil tanker plate and precision plate, and sign blanks sit in that family as their own entry.

Sign blanks and license plate blanks are different products with different buyers: sign blanks are the general sign-making substrate, while license plate blanks are the dedicated vehicle plate strip documented on the coil-strip and full-range sites. Order sign blanks for shop, wayfinding, display and traffic signage; vehicle plates take the plate strip product.

The category pages held for this catalogue show no size table for sign blanks, but the supplier's Square and Rectangular sign blank detail pages publish the standard options in prose: alloys 1100 H14, 3003 H14, 5052 H38, 5454 H34 and 5754 H34; thicknesses 0.48, 0.81, 1.0, 1.27, 1.60, 2.0, 2.54 and 3.175 mm; mill finish, color coated or anodized surfaces; standard hole diameters of 3.175, 4.76, 6.35, 7.94, 9.53 and 12.7 mm — centred top and bottom, custom holes or no holes — and corner radii from 9.53 to 76.2 mm, with additional sizes, shapes and gauges available on special request. What is confirmed in writing per order is the specific order itself — blank dimensions, quantity and availability against those published options: the enquiry carries alloy if fixed, thickness, blank size, corner and hole requirements if any, and surface. Quantities and minimums are confirmed in the quotation.

Sign blanks in the plate family

Sign blanks sit in a plate family that also includes hot rolling plate, circle plate (the disc page), moulding plate, sign blanks plate, brazing sheet plate (the brazing page), stucco plate, tread plate, mirror plate, oil tanker plate and precision plate. Sign blanks are the flat, clean, print-ready member of that family — the product exists because sign making needs plate whose surface and flatness are the point, supplied as blanks rather than as general sheet the sign shop must select from. The category pages held for this catalogue give the product a name and a family but no size table; the standard options are published on the supplier's Square and Rectangular detail pages — thicknesses 0.48–3.175 mm, standard hole diameters of 3.175–12.7 mm, corner radii of 9.53–76.2 mm, and mill finish, color coated or anodized surfaces — and the practical specification for an order — thickness, blank dimensions, corner radius, mounting holes, surface — is fixed against those options and confirmed in writing per order. Sign fabricators ordering repeatedly usually fix a blank schedule once and reorder against it; first orders should include one finished sign's specification so the blank is quoted as a product, not as raw sheet.

Sign blanks also reward a sample-first route. A first blank order proves flatness, surface readiness for print or vinyl, and edge quality on your own line before a programme is committed — and since the blank is specified per order, the sample can be your exact production blank. Send the finished sign specification once, approve the blank against your own print and mounting process, and reorders become a simple reference-number exercise against the documented plate product.
