Average roughness (Ra) is fine for standard machining, but when the cuts get brutal—like flame cutting or heavy sawing—you need to measure the absolute extremes. Rz measures the distance from the highest peak to the lowest valley. A callout of Rz 300 isn't just a surface finish; it's practically a topographical map. This engineer eco hoodie celebrates the heavy structural steel world and the rugged professionals who thrive "from peak to valley." Whether on a construction site or in the QA lab, sometimes you just have to respect the rough terrain.
Bonne qualité de tissu, impression précise selon ce que j'avais demandé. Bon produit.
Tissu très confortable et belle coupe ! J'aime le dessin ! (je suis bricoleuse)
I'm really pleasantly surprised by the quality of this t-shirt! The order arrived faster than expected. The fabric is nice and feels durable—it's not that thin. The fit is perfect, not too tight and not too loose, and the color matches the pictures on the website.
The print is well done, the details are sharp, and it doesn't look like it will crack after washing (I'll wash it inside out to be safe!). It's very comfortable to wear and breathable.
