Aluminum Strip for Channel Letter
Aluminum strip for channel letter is a specialized material used in the fabrication of three-dimensional illuminated signs (channel letters). It serves as the structural frame for LED-lit letters, offering durability, weather resistance, and ease of customization for indoor and outdoor advertising applications.
MESSAGE
Overview
Aluminum Strip for Channel Letter is a specialized product used to create three-dimensional, illuminated signage for commercial advertising. It is produced by slitting high-quality aluminum coils into narrow strips with precise dimensions, ensuring good ductility, formability, and surface flatness. This material acts as the "frame" for channel letters, allowing for easy bending, cutting, and welding into various shapes, such as store signs and brand logos. It is preferred over materials like stainless steel or iron due to its lightweight, corrosion resistance, and cost-effectiveness.
Specification
1.Alloy：Common alloys include 1100, 3003, and 5052. 1100 alloy has excellent ductility for complex bending; 3003 alloy adds manganese for enhanced strength; 5052 alloy offers superior corrosion resistance, suitable for outdoor long-term use.
2.Temper：HO，H12，H14，H16，H18，H19，H22，H24，H26，H28，H32，etc.
3.Thickness：0.2mm-4mm.
4.Width：10-1000mm.
5.Color：Normal(RAL or Pantone)，Metallic，Pearly，Shining Pearl Flower，Wrinkle，Marble，Wooden，Chameleon.
Feature
1.Excellent Formability
High ductility allows it to be bent into sharp corners, arcs, or complex font curves without cracking. It can be processed into various letter styles (italic, bold, hollow) to meet design needs.
2.Lightweight & High Strength
Density of 2.7g/cm³ (1/3 of steel), reducing the load on installation structures (such as building facades, sign brackets). Meanwhile, it has sufficient strength to resist wind pressure and external impact for outdoor use.
3.Corrosion Resistance
Aluminum’s natural oxide film and optional surface treatments (anodizing, coating) prevent rusting. It maintains stable performance in humid, rainy, or industrial-pollution environments, avoiding letter deformation or discoloration.
4.Good Weldability & Adhesion
Can be welded with aluminum solder or bonded with adhesives (for attaching acrylic panels or LED strips). The smooth surface ensures tight adhesion with other materials, improving the durability of channel letters.
5.Cost-Effective
Lower raw material and processing costs compared to stainless steel or copper strips. Long service life (5-10 years outdoor) reduces replacement frequency, saving long-term maintenance costs for businesses.
Application
Aluminum Strip for Channel Letter is widely applied in making channel letters for multiple scenarios: it’s used for luminous signs in commercial stores (like retail shops, restaurants), large outdoor advertising billboards (on building rooftops, highway sides), and high-end brand image signage (corporate buildings, hotel lobbies), with features fitting different use needs.
