The powder-coated anti-rust steel frame is built with 8 sturdy 1.57"×1.2mm steel poles and 8 ground anchors to lock the structure firmly in place. It is equipped with thick 180g removable PE sidewalls that are waterproof and tearproof. The fully enclosed structure shields vehicles from rain, snow and strong sunlight all year round. Stick the supplied waterproof tape on every roof seam, overlap upper roof sheets over lower ones, then tighten screws onto the steel frame to stop water leakage effectively. Spacious enough to shelter cars, trucks and boats. It can also store farm tools & equipment or serve as a temporary outdoor party tent for multiple scenarios. Installation must be on flat hard ground like concrete. Do not set up directly on grass, dirt or gravel. If placed on lawn, lay a wood or concrete base first; fix the carport with expansion bolts when mounting on concrete floors.
