The ZERUST®/EXCOR® Z-CIS® Methodology

Questionnaire

Do you want to…

  • Eliminate corrosion concerns?
  • Achieve rust-free shipment yields of up to 100%?
  • Reduce money lost to corrosion by at least 10%?

We’ll show you how with the Z-CIS System!

The Zerust Corrosion Inhibiting System (Z-CIS) is the proven methodology for deploying the complex corrosion management systems necessary to ensure the protection of metal products shipments as they are handled by multiple (internal and external) stakeholders in transit around the world. ZERUST/EXCOR Z-CIS is proven to meet both the rust-free and contaminant-free requirements of various OEMs sourcing from a global supple base. After implementing a Z-CIS System, our clients generally realize total cost savings of at least 10% and rust-free shipment yields as high as 100%.

Z-CIS Five Phase Approach


All entities involved in your supply chain (internal and external) affected directly or indirectly by corrosion concerns are identified as stakeholders and contacted by a ZERUST/EXCOR representative.

Each entity completes a Z-CIS Questionnaire either independently or in the course of a phone interview, so the Zerust Corrosion Engineering Team can properly understand all potential root causes of corrosion at the start of the project.


The Zerust Team reviews the project scope, corrosion control system performance requirements and critical issues with all stakeholders.

The Z-CIS Deployment Proposal is distributed. This document outlines the work that the Zerust Team would need to perform, the cost associated with the project, our initial recommendations and any additional items/information required from the stakeholders.

Key stakeholders review and sign-off on the Z-CIS deployment proposal authorizing the Zerust team to start work.


The Zerust Team collects product samples from the manufacturing site, draws samples of all processing fluids from the production line, evaluates the climatic stress impact of the shipping route, updates process FMEA documents, reviews process control plans, etc.

Products and fluid samples are tested in one of our regional laboratories located around the world for corrosion management system compatibility.

The Zerust team recommends a corrosion protection system (several recommendations may be generated) in the Z-CIS Deployment Recommendations document.


A meeting is required with all stakeholders to agree on the corrosion protection system to be deployed.

The Zerust Team works with the organizations directly involved in the process change (if any) to deploy the recommended solution. The corrosion protection system is executed in a viable time frame.

Trial shipments are made and monitored to ensure that the new Z-CIS System is working properly.


Regular audits against the Z-CIS Deployment Recommendations document are conducted to ensure that the process remains in control and improvements implemented.
