The surface of the cast chock should be smooth and free of sand, cracks, shrinkage cavities, cold insulation scars, alluvial layers and other defects that affect strength and appearance. For chocks where steel plates are bent and welded, the quality of the welds must be ensured and no cracks, warps, skews or defects that hinder use are allowed, and sharp edges must be rounded. After passing the inspection, the surface of the chock should be coated with secondary asphalt paint or equivalent anti-rust material.
