The manufacture of a vintage decorative metal plaque uses specific materials which faithfully reproduce the appearance and quality of vintage plaques. We mainly use two materials: tin-plated iron (tin sign) and aluminum. Each of these materials has unique characteristics that contribute to the authenticity and durability of retro plaques.

Tinned White Iron Plate (Tin Sign)

Origin and Use First of all, tinned white iron, commonly called "tin sign", is a traditional material that we have used in the manufacture of plates since the 19th century. It is a sheet of iron coated with a thin layer of tin to prevent corrosion and improve durability. This material was very popular for advertising signs, nameplates and wall posters.

Characteristics of the plate.

• Durability: Tin-plated tinplate resists corrosion thanks to its tin coating, which extends its lifespan.
• Aesthetics: It offers a smooth, glossy surface, ideal for high-quality prints. Colors appear vivid and details are well defined.
• Authenticity : Using tin-plated iron for advertising signs allows for an accurate reproduction of vintage signs, as this material was commonly used at the time.
• Ease of Handling: It is relatively easy to cut, stamp and shape, which allows you to create varied and complex designs.

Manufacturing Process To begin, we cut sheets of tinplate according to the desired dimensions. Then we roll or fold the edges for safety and aesthetics. Subsequently, we apply a high-quality print to the surface, followed by a protective layer to preserve the colors and patterns.

Aluminum plate

Origin and Use Next, we use aluminum, a modern material, to make plates because of its many advantageous properties. Lightweight, durable and corrosion resistant, it is ideal for plates intended for interior and exterior use.

Characteristics of the aluminum plate 

• Lightness: Aluminum is much lighter than tinplate, which makes the plates easier to transport and install.
• Corrosion Resistance: Naturally resistant to corrosion, aluminum is perfect for humid or outdoor environments.
• Versatile Finish: We can anodize, paint or print directly on aluminum, offering great flexibility in terms of finishes and colors.
• Durability: Aluminum is robust and resists shock and bad weather, ensuring a long life of the plates.

Manufacturing Process of the plate.

To begin, we cut aluminum sheets to the required specifications. Next, we anodize the surface to add a layer of protection and improve paint adhesion. Next, we print or engrave the designs and texts, then apply a layer of protective varnish to ensure a durable and hard-wearing finish.

Conclusion

In conclusion, the choice between tinplate and aluminum often depends on the desired style and intended use of the retro signs. Indeed, tinplate is ideal for those looking to capture the authenticity and charm of traditional vintage signs, while aluminum offers a more modern option with benefits in terms of lightness and durability. In both cases, these materials make it possible to create high-quality retro plaques that combine aesthetics and functionality.
