Metal or acrylic. You're overthinking it.
Look, I've built both for 16 years. Metal signs win for non-lit durability and high-end look. Acrylic channel letters win for illuminated storefronts on a budget.
Stainless steel 304 will sit outside for 10+ years. Acrylic face on a channel letter? You get 5-8 years before UV yellowing if you pay for Mitsubishi or Degussa. Domestic acrylic starts yellowing in 1-2 years.
That's the real trade-off. Not style. Fading and replacement cost.
Metal signs mean fabricated letters, usually stainless steel or aluminum. Non-lit, or halo-lit with LEDs behind. Acrylic signs mean channel letters with acrylic faces, or full acrylic light boxes.
Nobody sells a "metal vs acrylic sign" as a single product. It's about construction.
Here's what nobody tells you: the metal is just the housing. The acrylic is the face. You can have both in the same damn sign.
Our stainless steel letters are all metal, no acrylic. Our aluminum letters are weight 1/3 of steel and naturally rust-proof. The acrylic version is a separate animal.
Stainless 304. 18% chromium, 8% nickel. Density 7.93 g/cm³. Common thickness 1.0-3.0mm. That's a sign that survives a decade outdoors, no paint needed if brushed or mirror finish.
For coastal or industrial zones, use 316. It has 2-3% molybdenum. Costs 20-30% more than 304. For a strip mall in Ohio, 304 is fine. For Miami Beach, pay for 316.
The ugly truth is most sign shops order 304 for marine environments because the client can't tell the difference. Then the pitting starts at year three. I've seen this go wrong with a hotel in Tampa. They saved $400 per sign. Spent $8,000 replacing them.
Metal letters don't have to be lit. That's the point. A brushed stainless logo on a stone wall looks expensive. You don't need LEDs.
Aluminum is the budget metal. Weight 1/3 of steel, 8-12 year outdoor life. It won't rust. But it dents easier than steel.
Acrylic face light transmittance is 90-92%. That's why it's the standard for illuminated channel letters. Light passes through, the metal can forms the letter shape.
But acrylic is not all equal. Domestic acrylic starts yellowing in 1-2 years. UV-resistant acrylic from Mitsubishi or Degussa lasts 5-8 years.
Here's what nobody tells you: most factories quote the cheap domestic acrylic by default. Ask what brand of acrylic sheet they're using. If they can't name it, walk.
Our front-lit channel letters use UV-resistant acrylic on request. You pay a few dollars more per letter. You don't replace faces in two years.
Acrylic light boxes are another story. They're $80-250 per square meter at factory pricing. Great for menu boards or storefront signage. But they're bulky, and the acrylic face is a big flat target for wind and impacts.
Let's talk real money. Factory price per letter, not installed US retail.
US retail installed is $200-700 per letter for front-lit. Factory-direct saves 50-65% on product. You handle installation and import.
So a non-lit stainless letter costs you $25. A front-lit acrylic letter costs you $50. Double the price for lighting.
The ugly truth is most storefronts need lit signage. Local codes often require it. So you're not choosing metal vs acrylic. You're choosing how to light it.
Factory price isn't the final number. Shipping and tariffs add up.
Express for small orders: 7-15 days, $30-100. Air freight: 10-20 days, $4-12 per kg. Sea freight LCL: 50-70 days, $80-200 per cubic meter.
US Section 301 tariff on signs is roughly 30%. So a $1,000 factory order might cost you $300 in tariff. That's not hidden. That's US Customs.
Even after shipping and tariff, you save 50-65% versus US retail installed. A local sign shop quotes $500 per letter installed. We ship the letter for $60.
Metal letters, especially stainless 304, need almost nothing. Wipe them once a year. They don't fade.
