I've watched sign shops pay $800 for a front-lit letter. Same 304 stainless, same Samsung LEDs. We ship that letter for $120.
Here's what nobody tells you: most "factory direct" websites you find on Google are trading companies. They don't own a factory. They take your order, mark it up 20-30%, and pass it to a factory like mine.
That markup is your money. Buying from an actual factory matters, but only if you know how to check.
The ugly truth is that many buyers get burned because they don't ask the right questions. They see a cheap price, wire money, and six weeks later get a crate of warped aluminum with LEDs that flicker. Don't be that buyer.
We're Aochuang Sign. Lu'an, Anhui, China. Founded 2010. 3,000m² production floor, 50+ workers, exports worldwide. I'm not going to waste your time with corporate fluff.
Factory direct means you talk to the people who cut the metal, not a middleman. That saves you 50-65% on product compared to US retail installed prices. A basic front-lit channel letter that costs $20-80 from a factory goes for $200-700 installed in the States.
But here's the catch: factory direct also means you handle the logistics, the customs paperwork, and the quality vetting. Nobody's holding your hand. If you're a sign shop or contractor ordering 20 letters, that's fine. If you're a business owner ordering one sign for your own storefront, you might be better off with a local installer who eats the mistakes.
Look, I'm not going to pretend we're the right fit for everyone. We have a 1-piece MOQ, which is rare. But small orders cost more per piece because setup time is the same whether you order one letter or a hundred.
Stainless steel 304 is the workhorse. 18% chromium, 8% nickel, density 7.93g/cm³. That's the material for stainless steel letters that'll stand outside a strip mall in Ohio for 10+ years without issue. Common thicknesses run 1.0mm to 3.0mm. Finishes: brushed #4, mirror #8, PVD, powder coated.
If your job is within five miles of salt water, pay for 316. It's got 2-3% molybdenum, costs 20-30% more than 304, but it lasts 15+ years in marine environments. I've seen 304 rust in Miami Beach after three years. Cheap bastards thought they'd save $2 a letter.
Aluminum is different. We sell aluminum letters too. Weight is one-third of steel, naturally rust-proof, 8-12 year outdoor life. Thickness from 1.0mm to 1.6mm. Finish it with anodizing or powder coat. It's not as rigid as steel, so if your sign is over 2 meters wide, you need internal bracing or thicker material.
Here's the brutal honesty: domestic Chinese acrylic (when we pair it with metal faces) lasts 1-2 years before yellowing. Imported UV-resistant acrylic from Mitsubishi or Degussa lasts 5-8 years. Same sign, double the material cost. Tell your customer the truth. If they want cheap, they'll call you back in 18 months. Not my problem, but it should be yours.
Factory prices per letter: stainless steel non-lit $15-40, aluminum $10-25, back-lit halo $35-120, 3D fabricated $40-120. Light boxes $80-250 per square meter. That's not retail; that's what you pay before shipping and tariffs.
Shipping will eat your savings if you're not careful. Express for small samples: $30-100, 7-10 days. Air freight for medium orders: $4-12 per kilogram, about 10 days. Sea freight LCL: $80-200 per cubic meter, about 65 days. A full 20-foot container: $1,200-3,000.
Then add the US Section 301 tariff on signs: roughly 30%. Don't forget that. I've watched American buyers celebrate their $5,000 savings and then get a $1,500 customs bill. That's not a factory problem, but a smart buyer factors it in from day one.
Look, I price our stainless letters at $120 for a typical front-lit letter with Samsung LEDs. US installed retail for that same letter is $400-700. You do the math. But if you order one letter, sea freight LCL costs more than the letter itself. Order volume matters.
CE marking costs 20,000-50,000 RMB and takes 2-8 weeks. Most factories say they have it. Ask to see the certificate with today's date on it. A PDF from 2019 means nothing.
UL 48 is the big one for US electrical signs. It costs $4,000-15,000, takes 4-9 months, and requires quarterly audits. We don't keep UL listed products as stock. If you need UL, we'll manage the certification process for your specific sign model, but you're paying for it and waiting for it. Don't expect UL on a $60 letter from any factory.
ETL is a cheaper alternative to UL, about 10-30% less. CE is fine for Europe, but not the US. IP65 means dust-tight and water jets from any direction. That's the minimum for outdoor. IP66 for coastal. IP68 for submersible — overkill for most signs.
Here's what nobody tells you: a factory's ISO 9001 certificate doesn't mean their quality is good. It means they have a documented process. I can show you a process document. That doesn't stop a worker from using cheap LED modules unless your QC checks for it. We use Samsung, Osram, or Lan Jing. Cheap ones last 12-18 months. Ours are rated L70 ≥50,000 hours, real lifespan 5+ years. Big difference.
We're transparent about this. Design confirmation takes 1 day. Laser cutting with ±0.1mm tolerance: 1-2 days. TIG welding and bending: 1-2 days. Grinding and polishing: 1-2 days. Acrylic face CNC: 1 day.
LED assembly: 1-2 days. Sealing with neutral silicone: 1 day. Then 8-12 hour aging test. 100% QC inspection. Export packaging with foam, carton, and plywood crate. Total lead time: 7-15 days. That's for standard orders, not UL, not custom finishes like PVD which add 3-5 days.
I've seen this go wrong: a customer sent us artwork with hairline strokes. Looked great on screen. We cut it, bent it, and the stroke broke. Rookie mistake. If your design has anything thinner than 2mm, expect problems. Talk to us before you finalize.
We don't do installation.
