As a warehouse cage maker, Xintongnuo sells standard sizes (800*600*640mm, 1000*800*840mm, 1200*1000*890mm) but more often builds non-standard cages. Many buyers do not realize non-standard splits into two types; here is the clear line. The first type is the small non-standard cage: the outer dimensions stay standard, while square tubes, angle steel, casters, hollow panels, or other auxiliary parts are added to the bottom or as fittings. Because the dimensions do not change, no new tooling is needed; production is fast and the minimum order is low. The second type is the large non-standard cage: the outer dimensions themselves are non-standard and require new tooling. These are designed around the customer's specific inquiry; Xintongnuo's minimum for large non-standard work is 20 units. Below that, lead times run long and prices run high. Common non-standard directions include: stackable, lined, multi-layer, rack-mounted, over 2 meters long, lidded, powder-coated, and caster-equipped. Tell Xintongnuo your material size and use case, and we will judge whether small or large non-standard is the right path.
