I am currently in search of a heavy-duty handle capable of supporting loads up to 50 kg. I'm particularly interested in designs that incorporate wheels for easier maneuverability. If your factory has similar products that fit these criteria, I would love to explore those options. Additionally, please provide any details on available materials, durability features, and customization options. I'm eager to understand how your offerings can meet these needs. Looking forward to your suggestions and potential product recommendations from your lineup.
