What we do best
We provide effective, professional and cost-effective corrosion engineering services to clients all across Africa.
CORROSION TESTING
We have the capability to perform a wide range of tests related to evaluating the corrosion resistance and corrosivity of different materials.
FAILURE ANALYSIS
We use our analytical, metallographic, and chemical techniques to identify the factors that lead to the deterioration of any product or a piece thereof.
METALURGRAPHY
Corrosion Lab can help you analyse the structure of metals and alloys using techniques such as optical and electron microscopy.
MECHANICAL TESTING
We provide assistance with a wide range of tests to determine the material’s mechanical properties, independent of geometry.
MATERIALS SELECTION
We also provide materials selection solutions to minimise the costs without compromising on the product performance goals.
PRODUCT & EQUIPMENT SUPPLY
We can supply a wide range of product and testing equipment for use on-site and/or in a lab which can assist in the control of corrosion.

Try Our Process
Research & Analysis
Normally, the first step we take is to understand the root cause of the problem. To do this we spend enough time in the laboratory doing related research work and analysing all data.
Roadmap Planning
Once we have enough information about the problem, we begin brainstorming solution and develop a well-planned and well-documented roadmap to help us combat the problem at hand.
Execute & Monitor
With a good understanding of the problem and flawless plan in place, all that’s left is to implement the solution and monitor the changes to ensure there are no side effects we could have missed.
