Corrosion Protection

Steel is commonly used material in any kinds of construction. In steelworks, the favor of durability is an important matter to consider. However, when faced against the environment, steel may corrode and damage easily. As an alternative, Fiberglass Reinforced Plastic (FRP) is highly favored to replace some steel part. In offshore mining where the construction is surrounded by salt water, FRP is highly recommended for its durability against salt water, because FRP does not easily affected by wet environment and it is cost efficient.

There are various protections and coating technology to maintain steel structures against corrosion. One example is the weathering of iron alloy layers of the galvanized coating can give the appearance of superficial rusting many years before the durability limit has been reached. Where galvanized steelwork is affected by ‘white rust’ (wet storage stain) this should be removed with a stiff brush and washed with water before subsequent pre-treatment and coating. Although there are solutions to protect steel structures against corrosion, it does not come cheap. Consequently, cost effective corrosion protection of structural steelwork should present little difficulty for common applications and environments if the factors that affect durability are recognised at the outset. Therefore it is important to recognise the corrosivity of the environment to which the structure will be exposed, in defining clear and appropriate coating specifications, and in ensuring the correct application of coatings by trained operative.

FRP is the best solution to replace easily corrode applications. It is light weight, non-corrosive, strong and easily maintained. FRP is cost efficient which has been advantageous in various applications and to replace many steel applications. For information about our FRP products, please contact Surya Cakra Mandiri.
