How much is a foldable cage? No blanket answer; price stacks from several factors. First, size. An 800×600×640 and a 1200×1000×890 use very different steel. Second, wire diameter. 5.8 mm and 6.2 mm differ in load and cost. Third, bottom channel. Channel thickness and structure follow the load; heavier loads call for thicker channel. Fourth, standard vs. non-standard. Standard specs have existing tooling for negotiable pricing; non-standard work needs custom design and setup, raising unit price at small volumes. Fifth, raw-material market. Steel price is the main driver; cage prices move with steel up and down. For an accurate quote, send size, load, stacking layers, and standard/non-standard status; Xintongnuo staff price it against the current steel market.
