For tin plate coils secured with chains, which edge protectors should be used?

Metal and black rubber edge protectors are the optimal choice for securing tin plate coils with chains due to their ability to effectively distribute the load's pressure and protect both the cargo and the securing equipment. Tin plate coils, being heavy and potentially sharp or susceptible to damage, require edge protectors that can withstand significant tension and pressure without degrading or compromising the integrity of the coils.

Metal edge protectors provide durability and strength, essential for maintaining the stability of the load during transport. The black rubber component adds an additional layer of protection by cushioning against abrasions and preventing the chains from slipping, which ensures that the load remains secure throughout its journey. This combination not only safeguards the product but also enhances the overall security of the load by minimizing the chances of movement.

Using plastic edge protectors could result in excessive wear or breakage under heavy loads, while wooden protectors may not provide the necessary strength and could be less effective in preventing damage at critical pressure points. The option suggesting that none are needed does not consider the importance of protecting both the load and the securing system during transport. Therefore, the selection of metal and black rubber edge protectors aligns perfectly with best practices in load securement for such applications.
