If you are sourcing light-up letters from China, the difference between suppliers shows up two years later - in dark spots, rusted edges and failed power supplies. Here is how we build them, what drives the price, and how to get a fast sample.
Why Buy From a Factory, Not a Trading Company
Dongguan Bolang Advertising Sign Co., Ltd. was founded in 2012 and runs its own 2,000 m2 factory in Humen, Dongguan, with a 30-person team. Cutting, bending, welding, painting and wiring all happen under one roof, so the price is a factory price and the lead time is ours to control. Trading companies add a margin and lose control of both.
Channel Letter Types We Build
- Stainless steel channel letters - the outdoor default: weather resistant, strong 3D look, ideal for chain storefronts
- Mini channel letters - small faces, fine detail, popular for in-mall shops and interior signs
- Perforated (punched) letters - one sheet punched and lit, very bright at distance, made for rooftop letters
- Flat acrylic letters - acrylic face with a metal return, the cost-effective choice for smaller shops
How Our Channel Letters Are Made
- Artwork check - font file, size, colour, lighting mode
- Sample letter - batch orders are approved on a real sample first
- Laser cutting, bending, welding and grinding
- Painting, powder coating or plating
- LED layout, wiring and an ageing test before packing
- Export packing, then installation or shipping
Every stage can be photographed for you, and pre-shipment inspection at the factory is welcome.
What Drives the Price
Quotes for light-up letters vary widely for the same nominal square metre, because the price depends on the letter material (stainless steel, aluminium or acrylic), sheet thickness, letter height and stroke complexity, LED and power supply brand, and whether a steel frame and high-level installation are included.
Treat any figure as an indicative range only - the real number is calculated from material, craft, size and installation. Send your artwork and we will itemise it line by line.
Sampling, Lead Time and Shipping
Standard letter orders usually ship within a few working days after artwork and sample approval. Volume orders are scheduled by quantity and process. Projects with rooftop or high-level installation add a site schedule on top. We can ship worldwide and pack for export; tell us your destination port and we will quote the suitable method.
Quality Control and Warranty
- Fully welded and ground shells, sealed faces - no light leaks
- Waterproofed cable joints and a low-mounted power supply to avoid standing water
- Even illumination, checked against the letter depth before shipping
- Ageing test on every batch before packing
Warranty terms for LED and structure are stated on the quotation and contract according to product and environment.
