How to Choose Aluminum Strips for Channel Letter?

Table of Contents

Aluminum strips for channel letters are commonly made of 1000 series aluminum alloys, which have good corrosion resistance and formability. When making channel letters, you first need to cut the aluminum strip into the required shape and size according to the design requirements. The aluminum strip is then fixed to the frame or outline of the channel letters, usually using glue, screws or welding. Finally, a light source (usually an LED light) needs to be installed to provide a light effect. The light source is installed inside or on the back of the channel letters and transmits light through transparent or translucent materials, making the borders or outlines of the channel letters shine brightly at night or in low-light environments. Yongsheng’s aluminum strips for channel letters can provide advantages such as being lightweight, durable, easy to process, and good in heat dissipation. We also supply aluminum strips with various treatments such as color coating, mirror surface, which can be used to make channel letters and achieve various attractive effects and performance!
