While the initial cost of galvanizing may add up to 50% to the cost of the reinforcement, this cost premium as a percentage of total building cost is always significantly less than this value.
Yidao supply professional and honest service.
The overall cost in using galvanized reinforcement in concrete construction depends largely on the extent to which it is used throughout the structure. For example, it is rarely necessary for the structural core or internal elements of a high rise building or the deeply embedded components of large abutments and foundations, to be galvanized. In these situations, it may only be necessary to use galvanized reinforcement in surface exposed elements or where foundations and the like may be affected by aggressive or fluctuating groundwater.
In building construction, it is generally found that the cost of galvanizing increases the overall cost of concrete as-placed by about 6-10% depending on the size and type of bar used, the galvanizing price and the quantity of steel per cubic meter of concrete. On average, the cost of the reinforcement would not be more than about 25% of the total cost of the concrete as placed. Considering that the cost of the structural frame and skin of a building normally represents only about 25-30% of total building costs, the additional cost of galvanizing reduces to between 1.5-3.0% of total building costs. This premium reduces to as little as 0.5-1.0% if galvanizing is restricted to surface panels only. However, when taken against the total project cost or final selling price, the added cost of galvanizing becomes very small indeed, often not more than 0.1-0.2%.
When the costs and consequences of corrosion damage to a reinforced concrete building are analyzed, this extra cost of galvanizing is often seen as a very small investment in long-term corrosion protection.
