Is there any equivalent to a McMaster-Carr or Grainger supplier in China? One that has all kinds of construction/building/laboratory supplies available all in one online shop? Doesn't have to be in English. All I know about are local markets and hardware stores but going there everytime I need something isn't exactly convenient and can be hit-or-miss.
(If this should be posted in the Business Announcements forum, I apologize in advance, not quite clear on the difference)
