Steel Protection

Corrosion of our buildings is one of the most visible defects affecting reputation as well as costing the company or building owners. Rust / corrosion to steel structures, external screens, equipment and fixings are all preventable with the correct...

Carbon Steel is Iron alloyed with carbon in varying percentage and other metals in small quantities such as nickel or tungsten to suit the strength and behaviour characteristics required. Stainless Steel is Iron alloyed with a min of 12% chrom...

a. It is the carbon impurities that are added to Iron to make a strong and usable alloy like Steel that accelerates the corrosion process.

Uniform Corrosion is the attack of a metal at essentially the same at all exposed areas of its surface. At no point is the penetration of the metal by corrosion twice as great as the average rate. Concentration Cell Corrosion is corrosion ...

4.1 Selection of Materials 4.1.1 By selecting a metal least likely to corrode in the design phase the potential for costly corrosion repairs is reduced. This can be achieved in a number of ways – a. Substitution of metals with other less-...

5.1 In a metal to metal contest with moisture as the catalyst, the metals higher on the list will sacrifice themselves for metals lower on the list. So it is ok to have run off from zinc to copper but not from stainless to zinc.

6.1 Above all you need to carefully consider each element of the building that contains a metal then decide whether it can be substituted with a less or non-corrosive material. 6.2 “Prevention is better than cure” – refer cases below where the...

Above - Units located on the beach - salt air blows through the unit and becomes lodged at "choke" point like this door frame - Unit is air-conditioned - so at the door junction (where the salt has been deposited) - COLD unit air meet...

8.1 Structural steel requires maintenance to ensure that the coating system is kept in good condition to continue to protect the steelwork from premature degradation. Surfaces need to be washed down to remove the salts that accelerate corrosion o...
