The cargo body of 4.2m light truck often carries sand, farm supplies, fresh produce and bulk materials. Rainwater, moisture and salt erosion will easily cause rust, paint peeling and steel plate perforation. Anti-corrosion maintenance is essential to extend the service life of flatbed, box and stake cargo body, which is often ignored by operators engaged in urban-rural delivery, farm produce transport and building material freight. Light trucks running in rainy, humid, coastal or rainy regions of Africa suffer from faster rusting. Proper anti-corrosion work helps you cut high cost from frequent body repair and replacement.https://www.hjtrailer.com/truck/box-truck/isuzu-box-truck.html
Anti-corrosion treatment at the new body production stage lays the foundation. Our 4.2m light truck cargo bodies go through sand blasting, primer, intermediate coat and topcoat painting. Weld seams are sealed specially for rust resistance. After receiving the new truck, avoid carrying highly corrosive cargo immediately. Check paint surface, weld seams, corners and rivets for scratches. Corners are high-risk rust areas. Touch up paint promptly once steel is exposed.
You also need protection during loading and unloading. Sharp building materials and crushed stones scratch paint easily. Wear-resistant rubber strips and bump pads are recommended. When transporting wet farm goods, fertilizer or salty cargo, lay waterproof sheets to avoid standing water soaking the floor. Clean dirt, fertilizer residue and water inside the body after every trip. Corrosive debris trapped in gaps is the main cause of rust spots. Make sure the body dries fully before closing doors.
Carry out regular anti-corrosion inspection. Focus on floor welds, hinge joints and drain holes at the bottom of cargo box. Blocked drain holes trap water inside and accelerate rusting for box trucks, so clear them regularly. Apply anti-rust grease to hinges, latches and bolts to prevent seizure. If rust spots appear, polish and remove rust completely before applying anti-rust primer and topcoat. Painting over existing rust will not stop corrosion spreading inward.
For 4.2m light trucks exported to Africa and the Middle East, hot-dip galvanized body and stainless steel floor are optional upgrades for humid rainy seasons and salty dirt roads. Regular anti-corrosion maintenance reduces the risk of rust perforation and deformation, and keeps your daily delivery of general goods, fruits and building materials running smoothly.
