不銹鋼無縫管對比於有縫管，更能承受更多的壓力；不銹鋼管不易生銹的特性也廣泛地運用在各種食品級、醫療級配管。但不銹鋼相較於鋁、銅等材質，是相對難加工及磨損刀片甚劇的，可以說是耗時費材。尤其是外徑大內徑大的尺寸，不少業界同仁更至視為畏途。

例如之前有一筆外徑內徑的美標訂單，每米長重量公斤的實心棒材，便有公斤多是廢料，實心空心比例高達.倍。然而，倘若經由敝公司的客製化無縫管訂製，一來一體成形，無須多花時間鑽孔，是謂省時；二來重達公斤的米實心棒，倘若假設每公斤元，那米長就是元的成本。相較之下，訂製米空心管只需要將近公斤，是謂省料，而我們的價格總單價也絕對遠低於元；三來現成的空心管材只要經由剪裁、車牙、倒角等，就可以廣泛應用於螺母、汽車零件、快速接頭、食品級管材等成品，可謂好加工。在節省了成本，加工時間的雙重優勢下，不但增加了獲利空間，更有利於台灣的企業搶單。對於汽車工業、造船工業、金屬加工、工程機械業都可以互利進而創造雙贏局面。
