What Is The Cost Of HDG?

Hot-dip galvanising has steadily become more competitive and often less expensive on an initial basis than other corrosion prevention systems.

Many other corrosion protection systems, including paint and powder coatings, have seen cost increases of 100% or more over the past five years. To make matters worse, these protective systems often require frequent maintenance, which increases life-cycle costs (LCC) even further — direct maintenance costs typically reach 2-5 times original costs, while indirect costs often surpass 11x direct repair expenses.

With the rising costs associated with other coating systems and maintenance expenses, more specifiers consider life-cycle costs when selecting their building materials. Life-cycle cost analysis offers more comprehensive cost consideration since it takes into account both initial costs and ongoing maintenance expenses for a project’s lifetime. Given that hot-dip, galvanised steel requires no upkeep for 70+ years in most environments, Life cycle costs often equates directly with initial costs; making hot-dip galvanised steel an economical and environmentally sustainable choice.

Therefore, when specifying materials for any project, specifiers must consider more than just the initial cost when choosing protection systems. Accounting for long-term costs like service life extension, expected first maintenance cycle time, and economic impacts related to initial and continued upkeep will provide more accurate predictions of its effect on future generations.
