Our factory experts at WR Profiles reveal why gram weight is the only honest way to price LED aluminum channels. WM-29 vs. XT-164 comparison.
Don’t Get Tricked by “Base Thickness”: A Factory Insider’s Guide
If you are sourcing LED aluminum profiles for your projects or distribution business, you probably always ask: “What is the base thickness? 0.8mm or 1.0mm?”
But here at WR Profiles, we want to show you a secret that most suppliers won’t tell you: The thickness of the base is only half the story.
The Comparison: Why “Thin” can be “Heavy”
Let’s look at two of our most popular 17x7mm surface-mounted models from the wrprofiles.com catalog. On paper, one sounds “thicker,” but the reality is in the weight.

Model WR-WM-29 (The Red One): This model has a 0.8mm base. It sounds strong, but to keep the cost down for budget-sensitive projects, we designed it with slim side walls.
Gram Weight: 77g per meter.
Live Price (2nd April 2026): 2.369 RMB/m.
Model WR-XT-164 (The Green One): This one only has a 0.6mm base. You might think it should be cheaper, right? At WR Profiles, the answer is No. We engineered this model with reinforced, heavy-duty side walls.
Gram Weight: 88g per meter (That’s 11% more aluminum than the 0.8mm version!).
Live Price (2nd April 2026): 2.707 RMB/m.
The “WR Profiles” Golden Rule: Gram Weight = Real Value

In our Jiangmen factory, we don’t just sell “thickness”; we sell aluminum content. Since raw 6063-T5 aluminum is priced by weight, the WR-XT-164 costs more because it actually contains more material.
Why does this matter for your business?
Professional Heat Sinking: More aluminum weight means your LED strips stay cool and last much longer.
Structural Integrity: WR Profiles’ heavy-wall designs won’t bend during installation, and our PC diffusers click in with a perfect, firm seal every time.
Transparency: We want our clients to know exactly what they are paying for. A “thick base” with “paper-thin walls” is a common way to hide a low-quality product.
My Pro Tip for Your Next Order:
Next time you compare quotes from China, don’t just ask for the thickness. Ask: “What is the gram weight per meter for this WR Profiles model?” That is the only way to know if you are getting a lightweight “economy” version or a heavy-duty “professional” version.
