Marking of packages

Through a correct and complete marking of packaging will create the conditions to avoid misuse, accidents, wrong delivery, mass and volume losses and customs penalties. We do marking very clear and precise on ERW Steel Pipes & Tubes. You should contrast clearly with the package, usually it is applied in black color.
