Als Ronn Stol Link Kette Fabrikant beschwéiert fir 30 Joer, ass eis Fabréck mat der ganz wichteg Period vun Chinese Ketten maachen Industrie Evolutioun bleiwen an zerwéiert Catering fir Biergbau (Kuel Grouf besonnesch), schwéier Levée, an industriell vermëttelen Ufuerderunge op héich Stäerkt Ronn Stol Link Ketten. Mir halen net op de féierende Round Link Kette Hiersteller a China ze sinn (mat alljährlechen Versuergung iwwer 10,000T), awer halen eis un net-stoppend Kreatioun an Innovatioun.

Schlëssel
| 1 | Traverse Mëttellinn vum Link | l | ass déi multiple Pitchlängt |
| p | ass den Terrain | dm | ass de Material Duerchmiesser wéi gemooss |
| ds | ass de Schweess Duerchmiesser | e | ass d'Längt vun der Schweess dimensional beaflosst |
| w3 | ass d'intern Breet op der Schweess | w2 | ass déi extern Breet iwwer d'Schweiß |
