I've been on this factory floor for 16 years, and I can smell a fake quote from across the ocean.
Look, a 24-hour quote means nothing if the number's invented. Some sales rep in a Shanghai office will type a price without checking aluminum thickness, LED brand, or whether the letter needs a UL sticker. Then you order, and two weeks later you get an email asking for more money because "the size changed." The size didn't change. Their first number was a lie.
We don't do that here at Aochuang Sign in Lu'an, Anhui. Founded 2010, 3,000 square meters of production, 50+ workers. When I say you get a quote in 24 hours, I mean a line-item number based on a real drawing, real material, and real labor.
Here's what nobody tells you: "factory direct" is the most abused phrase in the sign business. I've seen trading companies mark up channel letters 30% and still call themselves factory direct because they own a warehouse next to a factory. That's not the same thing.
You want the actual factory floor. The one with the laser cutter running ±0.1mm tolerance, the TIG welders, the acrylic face CNC. That's us.
The ugly truth is most buyers overpay because they don't ask the right questions. They ask "how much for a 3-foot letter?" but don't ask what LED module is inside, what thickness acrylic, or whether the power supply is Mean Well or some no-name that dies in six months. I'll give you those answers before you even ask.
We make custom illuminated signs: front-lit channel letters, back-lit halo letters, rimless, dual-lit, stainless steel non-lit letters, aluminum letters, acrylic light boxes, and neon flex. MOQ is 1 piece. Not 50 pieces. One. That's rare in China.
A standard front-lit channel letters job runs $20-80 per letter factory price. Same thing installed by a US sign shop runs $200-700 per letter. You're saving 50-65% on product. That's not a sales pitch, it's arithmetic.
3D fabricated letters run $40-120 per letter depending on depth and finish. They're built with welded returns and can be lit or non-lit. For architectural jobs where the glow matters more than the face, back-lit halo letters cost $35-120 per letter. They use spacers, special mounting, and more LED labor. The premium look costs more because it takes twice as long to wire.
If you need non-lit exterior letters that survive salt and freeze-thaw cycles, stainless steel letters start at $15 for 304 and go up based on thickness and finish. A 304 letter with brushed #4 finish will last 10+ years outdoors. I've pulled 316 letters off a Miami Beach restaurant after 8 years and the only damage was from a hurricane debris strike.
Look, we can't give you a UL 48 sticker. That's a US certification, and it costs $4,000-15,000 plus quarterly audits. We hold CE, RoHS, and ISO 9001, which cover a lot of international work, but if your city inspector demands UL 48, you'll need to go through a national testing lab or a certified shop. We can build exactly to NEC Article 600 and UL specs, but the certificate itself isn't ours.
Can't also isn't in our vocabulary for rush jobs. Our lead time is 7-15 days for production, not 7-15 days after a two-month waiting list. Once the drawing is approved, the floor starts cutting. I've burned my hands on hot acrylic enough times to know that rushing the bending step creates weak welds. We don't rush, but we don't sit on your job either.
I've seen this go wrong: a guy ordered 20 channel letters without asking about LED lifespan. The factory used cheap modules that cost 1/3 of quality ones. Twelve months later, half the letters were dim and patchy. He paid $4,000 to relight a sign he'd just bought. That's a rookie mistake.
Here's our rule: SMD 2835 modules from Samsung, Osram, or Blueview (our standard) run 100-150 lumens per watt and last 5+ years in real conditions. L70 rating is 50,000 hours. Cheap modules last 12-18 months. The price difference per letter is maybe $6-12. You tell me if that's worth it.
Acrylic matters just as much. Domestic acrylic starts yellowing in 1-2 years under UV. Mitsubishi or Degussa UV-resistant acrylic keeps 90-92% light transmittance for 5-8 years. Over 2.5 meters, we automatically spec 5mm+ thickness because 3mm will bow and crack in wind.
For metal, 304 stainless is 18% chromium and 8% nickel. Density 7.93g/cm³. Common thickness 1.0-3.0mm. That's your strip mall Ohio workhorse. 316 stainless adds 2-3% molybdenum for marine grade and costs 20-30% more. If you're 500 meters from salt water, pay for 316. Otherwise 304 is fine.
Aluminum letters weigh one-third of steel and run $10-25 per letter. They won't rust, and with powder coat or anodized finish, they'll do 8-12 years outdoors. If you need a 4-foot letter on a facade that can't take steel weight, aluminum's the call.
Light boxes run $80-250 per square meter factory price. Neon flex signs run $30-200 per sign depending on shape and LED density. If someone quotes you $50 for a 2-meter neon flex sign with IP68, they're lying about something.
Here's what I need from you, and it's not a 20-page brief. Send me the text or logo file, the letter height in inches or mm, the mounting surface, and whether it's indoor or outdoor. That's it. If you don't know what material you want, I'll give you two options: the budget one that'll last
