FAQ
| Q1: | What materials do you use for Heavy Duty Truck Casting Fittings? |
| A1: | We use high-grade carbon steel and alloy steel. Carbon steel suits general chassis parts, while alloy steel handles high-stress connections with superior strength and fatigue resistance. All materials are certified. |
| Q2: | Do you accept custom orders? |
| A2: | We provide OEM and ODM services based on your drawings, samples, or specifications. Our team evaluates feasibility and delivers approved samples before mass production. |
| Q3: | What is your lead time and shipping method? |
| A3: | Standard lead time is 4–6 weeks after sample confirmation. We pack in export cartons and wooden crates, with flexible sea or air freight options and full tracking support. |
