Custom Double-Sided Channel Letters – Brushed Black Standoff Sign
Custom brushed black steel double-sided channel letters with push-through acrylic faces on both sides and LED illumination inside the channel. Standoff off-wall letters for corner storefronts, restaurants, cafes, retail and architectural signage. Factory direct OEM from Hongbo Signage, Guangzhou.
Product Overview
Hongbo Signage manufactures custom double-sided channel letters for storefronts worldwide. Each double-sided channel letter is a fabricated metal channel body with push-through acrylic faces on both the front and back. LED modules are arranged on the inner walls of the channel, facing each acrylic face, so a single letter delivers uniform, low-glare illumination with controlled LED spacing, designed to minimize dark bands and visible hotspots. The brushed black stainless steel returns provide a premium satin appearance, while the whole set mounts off the wall on stainless standoff posts or a projecting steel arm — making double-sided channel letters readable from both directions on corner buildings, narrow sidewalks and main-street storefronts. The channel body is precision-fabricated using laser cutting, bending and TIG welding, with the acrylic faces push-through mounted and silicone-sealed around the edges for improved weather resistance.
Key Features
- Brushed black steel construction: Premium stainless steel frame and returns with a consistent brushed black satin finish — durable, corrosion-resistant and visually refined for commercial and architectural facades.
- Double-sided push-through glow: Acrylic faces on both sides light up from LED modules inside the channel — legible day and night from both directions of foot traffic.
- Standoff / off-wall mounting: Stainless standoff posts or a welded projecting arm hold the set off the facade for a premium, floating look; wiring concealed inside the posts or raceway.
- Precision fabrication: Laser cutting, precision bending and TIG welding ensure sharp, accurate letter forms with clean joints and consistent dimensions across every character.
- Controlled LED illumination: High-brightness LED modules spaced to the channel depth — even brightness across both faces, designed to minimize dark bands and visible hotspots.
- Custom sizes and fonts: Manufactured to your logo, font, dimensions and letter depth — from a small boutique set to large storefront lettering.
Materials and Construction
The channel body is fabricated from 304 stainless steel with a brushed black finish (316 stainless available for coastal / high-humidity environments), chosen for corrosion resistance and a premium satin appearance. The acrylic faces are push-through mounted and silicone-sealed around the edges for improved weather resistance. Inside, high-brightness LED modules, light-diffusing acrylic and a weather-sealed certified power supply are sized to the letter set.
Why the deeper channel? A double-sided letter houses two LED banks plus the internal wiring channel in one body, so the channel depth typically runs 100–150 mm (4″–6″) — deeper than a single-sided letter. Mounting options include stainless standoff posts (50–150 mm off the wall), a projecting steel arm for blade-style corner signs, or a rear-access raceway sized to your wall type.
Typical Applications
- Corner storefront and fascia signs: Double-sided illuminated letters that read from both directions on corner buildings and narrow streets.
- Restaurant, cafe and food-service signage: Brushed black steel double-sided sets for restaurants, hotpot chains, coffee shops and bars.
- Retail and boutique storefronts: Premium illuminated lettering for boutiques, salons, spas and retail brand zones.
- Office and commercial building signs: Architectural off-wall lettering for corporate facades, mixed-use buildings and lobbies.
- Main-street and pedestrian-scale signage: Where customers approach from either direction and a flat wall sign only reads from one angle.
