This product is a fixing bracket matched for left-side tool boxes of heavy trucks, tractors, dump trucks and passenger coaches, mounted on the left vehicle frame to bear storage boxes, serving as OEM aftermarket replacement spare part. The one-piece forming structure balances high load capacity and long-term rust resistance. Besides standard in-stock specifications, we also provide personalized customization including dimension, hole layout and plate thickness to fit refitting demands of various special commercial vehicles.
①CNC Integrated Bending: One-piece automatic bending from whole steel plate without split welding seams to avoid cracking risks. Integral stamped reinforcing ribs on stress areas disperse vibration force from bumpy roads.
②Laser Precision Punching: High-precision laser positioning punching with hole tolerance within ±0.02mm, mirror copying OEM left-side mounting layout.
③Double Anti-Corrosion Process: Bottom electrophoresis penetrates steel micro-pores to block moisture; outer high-temperature matte black electrostatic powder coating forms dual barrier against salt and mud erosion, passing 480-hour neutral salt spray test.
①High Load & Anti-Deformation: Thick steel with reinforcing ribs avoids twisting or fracture even under full heavy tool load, ideal for harsh construction and mountain long-haul roads.
②All-Weather Durable Anti-Rust Performance: Double protective coating stays intact under extreme temperature, suitable for coastal areas and winter salt road conditions.
③Fast Modification-Free Installation: OEM mirror holes support direct assembly with original bolts, no cutting or grinding needed; single-person installation finished within 10 minutes.
