Design - Quality
No other protective coating for steel provides the long life, durability and predictable performance of hot dip galvanizing. An alloy of its steel base, a galvanized coating is unique in matching the design and handling characteristics of steel. As asset management and life-cycle costing become even more essential, after fabrication galvanizing provides the facility to design for a predictable, engineered result. Galvanizing is a once only process, committed to the concept of the maintenance-free use of steel, ensuring long service life and virtually eliminating disruptive maintenance. This long-term protection is well documented world-wide in terms ahead of any other protective coating, and galvanizing continues to find new applications in almost every field of engineering.
| The benefits of after-fabrication galvanizing | |
| Competitive first cost: | For many applications first cost is lower than alternative coatings. |
| Long life: | Often exceeding 30 years. |
| Lowest lifetime cost: | Low initial cost and long life make galvanizing the most versatile, economic method of protecting steel. |
| Reliance: | Specified to AS 4680 and equivalent World Standards. |
| Speed of application: | A fully protective coating can be applied in minutes. |
| Complete coverage: | All exposed steelwork is completely coated both internally and externally. |
| Ease of inspection: | The nature of the process is such that if the coating looks continuous and sound, it is so. |
| Coating toughness: | Alloy layers are harder than the steel on which the coating is formed. |
| Adhesion: | Metallurgically bonded to steel. |
| Coating thickness: | Galvanized coatings are distinctly thicker at corners and edges, an important advantage over most organic coatings which thin out in these critical areas. |
| Cathodic protection: | Electrochemical protection which takes place on any damaged areas. |
| Environmentally clean: | Non toxic. No volatiles. No ultimate disposal costs. |
| Faster construction: | An off-site finish, geared to fast-track construction. Requires no site repairs short of weld damage. |
| Top coats: | Top coats can provide: colour, chemical resistance, synergistically-extended life |
