When transporting angle steel, several precautions should be taken. First, ensure that the transportation vehicle is equipped with proper securing devices, such as straps, chains, and anti - skid mats. Stack the angle steel neatly and firmly, with the L - shapes interlocked if possible to prevent movement during transit. For long - length angle steel, use special supports to avoid bending and deformation. Protect the surface of the angle steel from scratches and collisions by placing soft materials between layers. In case of adverse weather conditions, cover the angle steel with waterproof tarpaulins to prevent rusting and damage.
