WHY IS OUR 3-LAYERED, PRE-GALVANIZED PRODUCT SUPERIOR?
| HOT DIP AFTER (The old way) | HOT DIP DURING (Limited Inside Protection with In-Line process) | HOT DIP BEFORE (The superior method that gives you the protection you need with a 3 step exterior process and a PURE ZINC/GALVANIZED INSIDE COATING) |
|---|---|---|
| 1. Minimal surface cleaning and temperature control means possible poor adhesion of zinc coating. | 1. Minimal surface cleaning and temperature control means possible poor adhesion of zinc coating. | 1. Continuous galvanizing of cold rolled sheet at the Steel Mill results in the BEST possible coating adhesion, thereby eliminating flaking and spot rusting. |
| 2. Lack of controls result in poor uniformity (pin holes) and adhesion of the zinc coating. | 2. Lack of controls result in poor uniformity (pin holes) and adhesion of the zinc coating. | 2. State of the art coating and temperature control guarantee a uniform coating which prevents pin holes and spot rusting. |
| 3. Hot rolled steel surface imperfections result in non-uniform zinc coating. | 3. Hot dip during exterior zinc application results in non-uniform zinc coating | . Hot dip galvanized interior surface provides the BEST corrosion protection. |
| 4. Zinc surface is unprotected resulting in white rust (zinc oxide). | 4. Zinc painted interior DOES NOT have the qualities of a pure galvanized coating or overall corrosion protection. | 4. A clear acrylic exterior coating plus a conversion coating gives added protection. |
| 5. Only standard lengths are available. | 5. Clear polymer coating protects against white rust. | 5. High strength base steel allows lighter walls resulting in lower handling and shipping costs. |
| 6. Cost factors are typically high. |
