Z & P traditionally throughout its history has offered coating services in its different forms both on-site and applied in coating plants. Since its early operations, coatings were offered with coal tar and polyethylene tapes that were replaced over time with materials and technologies that guaranteed greater performance and durability. Z & P in the 60s installed in its yard of Las Morochas, Zulia state of Venezuela, its first external pipe coating plant  with high density polyethylene (P.E.A.D.); Then, Z&P installed an external pipe coating plant with concrete to give it greater mechanical protection and weight to avoid buoyancy in the construction of underwater pipelines. Finally, in the 1980s, Z&P installed an external coating plant for pipes with fusion bonded epoxy coating (F.B.E.), for low and high pipelines service temperatures
