There are two ways to reinforce color coated steel coils: standard reinforcement and special

reinforcement.

• standard reinforcement

We protect the coils by adding cushioning materials and tightening them with lashing straps,

non-slip wooden blocks underneath to prevent movement, meanwhile, we use waterproof

package,and add desiccants to prevent against moisture.
