The main thing you need to know upfront is that the zinc plating isn't as heavy-duty as hot-dip galvanizing for constant salt spray exposure, so if you're parking near the coast for months on end, you'll want the black painted option instead, but for typical yard or driveway use it's fine and actually better than reagent grade for this.
We've got six weight ratings here—350, 750, 1500, 2000, 5000, and 7000 lbs—so most buyers go with the 1500 or 2000 lb capacity for standard single-axle trailers, and the tube diameters run form 48mm to 64mm depending on which model you pick, which covers pretty much any A-frame you'd encounter.
Height adjustment range is 420mm to 1295mm, model dependent obviously, and the wheel options are either rubber or plastic in 6-inch or 8-inch sizes, but the rubber ones handle better on gravel while the plastic ones roll easier on concrete, so pick base on your typical surfce.
ISO/TS16949 and CE certs are in place, and the warranty runs 1 to 3 years depending on the componnet—the wheel itself is the shorter end, the tube assembly is the longer—and we usually have stock on the 48mm and 57mm tubes but confirm lead time on the 64mm (check lead time, usually 2-4 weeks).
One thing you wouldn't think to ask: the plastic wheels have a higher load capasity per wheel than the rubber ones at the same size, roughly 20% more, so if you're pushing the upper end of the weight rating, go plastic.
Anyway, the custom labeling and bulk synthesis isn't really applicable here since these are mechanical parts, but our company can do custom tube lengths or paint colors if you're ordering 50 units or so, and the MOQ on standdard models is just 10 pieces.
Our MOQ is 500 units per model, but we can be flexible for first-time orders or custom requests—just reach out and we'll work something out.
Yes, we include copies of ISO/TS16949, CCC, DOT, and CE certifications with every order. Just let us know which ones you need in the shipping documents.
Absolutely—you can combine rubber and plastic wheels, and even different sizes like 6'' and 8'', as long as the total meets our MOQ. We'll adjust the packaging accordingly.
Standard lead time is 25-30 days after order confirmation. If you need a rush, we can sometimes cut it to 20 days for standard specs.
We wrap each wheel individually in anti-rust paper, then pack them in reinforced cartons or wooden crates depending on quantity. The zinc plating itself also gives solid corrosion protection.
