COMMONLY USED SUBSTRATES FOR CHANNEL LETTER SIGNAGE
Because of its unique properties, aluminium has become the substrate of choice for channel letter manufacture. The Channel Letter Factory is experts in the manufacture of aluminium channel letter signs.
Aluminium is a lightweight, durable and corrosion resistant substrate and used in applications ranging from traditional signage to extruded profiles for lightboxes, frames and POP display components. Aluminium channel letters can be manufactured manually, but the use of automated manufacturing tools is the new trend. Fully automated, channel letter benders provide computerized production environments that result in consistent fit, finish and 100% job accuracy with a quick production turnaround. Channel letter benders are extremely expensive and signage companies make use of outsourced services in this regard as a resource to compliment their existing production.
Aluminum is available in different thicknesses (0.9mm, 1.6mm, 2mm and 3mm) and finishes (plain, anodized, brushed anodized and plain brushed). Channel letters are joined using rivets, screws, glue and welding.
The job requirements will determine the thickness of the aluminium and joining method.
Acrylic is one of the most popular signage substrates in the signage and graphics industry. Available in a range of colours and thicknesses, acrylic can be used in the complete manufacturing process of channel letters or just as the “face” of channel letters where the return has been manufactured from aluminium. Acrylic is a very versatile substrate, but can prove challenging to work with for especially large scale or repeat projects.
