The high-strength steel car jack from Henan Probon Tools Co., Ltd. is built around a frame constructed from premium high-strength steel—selected by the company’s domestic first-class R&D team for its exceptional tensile strength, impact resistance, and durability. High-strength steel (typically with a tensile strength of 600 MPa or higher) allows the jack to handle heavy loads (often 2-5 tons) while maintaining a relatively lightweight design, balancing strength with portability. This material also resists bending, warping, or cracking during use—even when subjected to lateral pressure (such as when technicians lean on the vehicle during repairs) or accidental impacts. Henan Probon Tools, established in 2019, uses advanced manufacturing techniques (like laser cutting and precision welding) to shape and assemble the high-strength steel frame, ensuring consistent thickness and structural integrity across every unit. The jack’s critical components—such as the saddle, lifting arm, and base—are also made from high-strength steel to eliminate weak points. Each high-strength steel jack undergoes quality testing to verify load-bearing capacity (tested to 120% of rated capacity), impact resistance (via drop tests), and structural stability (at maximum lifting height), adhering to the company’s “quality first” concept. For professional auto repair shops, fleet maintenance teams, or users who prioritize long-term durability, this jack is a reliable investment. With a monthly production capacity of 1 million products, the company ensures that every jack uses genuine high-strength steel.
