How do you tell cage quality? From years of experience, Xintongnuo points to three key checks. First, welding. Passing material specs is not enough; mesh and base must be welded solid. Every wire intersection must be welded — no missed or cold joints; the base must be fully welded for strength. Second, high wire and channel. The cage body is high wire plus channel; wire material sets strength, reputable makers supply material reports, and large-mill wire is generally more consistent. Much of the load presses on the bottom channel, whose thickness decides whether the rated load is met. Third, galvanizing. Coating must be at least 8 microns thick, bright, spot-free, and smooth. These are details, but detail-slack shops slack on overall craft too. We ship to Japan, Europe, the U.S., and Korea, where buyers are picky about details — passing their bar is roughly the industry's strict standard.
