Go-to guide on zinc
We are currently the ONLY manufacturer to derive its surface colors directly from the ALLOY. RHEINZINK prePATINA blue-grey and prePATINA graphite-grey are two different alloys leading to different colors. Other zinc manufacturers have an alloy with a surface treatment to give the appearance of a different color. The distinction of having two different alloys is very important due to the fact that zinc is a ‘self-healing’ material and if scratched, RHEINZINK will re-patinate after periods of wetting and drying cycles.
- RHEINZINK is the ONLY zinc manufacturer with two different alloys. Learn more about ATSM B69-16
- Regionally-based company employees to provide support throughout the project.
- Experienced distributors and system partners with extensive zinc knowledge across the U.S., Canada and Mexico.
- Environmentally friendly material that offers up to 17 possible LEED points.
- Education - AIA CEU credits
European standards stipulate that a product must be marked by the manufacturer. Our RHEINZINK products are identified as follows to prove they are the genuine article:
- RHEINZINK coils and sheets: a continuous stamp on the underside of the metal
- Gutters and downspouts: continuous embossed stamp
- Accessories for gutters: embossed stamp
- Pallets containing gutter products: stickers applied to the packaging, including detailed product data
The RHEINZINK embossed stamp shown on our gutter products is an important mark of quality. This system includes almost 300 different parts and components, which are all matched in terms of dimensions, guaranteeing a perfect fit.
- DIN ISO 9001:2008 certified
- DIN ISO 14001:2004 certified
- Quality Zinc
The outstanding quality of RHEINZINK products in terms of materials and manufacture can be attributed to our many years of experience combined with a constant willingness to innovate. A uniform quality standard is ensured by our patented wide-strip casting and rolling mill, continuous monitoring of each stage of production, all mechanical and technological properties listed above as well as the dimensional tolerances of the material.
RHEINZINK is certified to DIN EN ISO 9001:2008 and is subject to voluntary inspection by TÜV Rheinland according to the stringent requirements of the QUALITY ZINC Criteria Catalogue. This recognized German monitoring board has developed its own quality label for zinc as a building material. A catalog of quality criteria lists all characteristic data for the material and permitted tolerances for the quality of the semi-finished product (coils and sheets). Monitoring is carried out every two months by an inspector from TÜV Rheinland, who arrives at the plant unannounced.
Inspection focuses on the quality characteristics going beyond the requirements of the standard, e.g. reduced deviation in the permitted thickness of only ±0.020 mm, reduced length / width tolerances of +2.0/-0 mm and increased proof stress (Rp 0.2).
Guaranteed quality. What is your benefit?
As the manufacturer, one goal is for our customers to put their utmost confidence in our products and company. To achieve this, we follow manufacturing standards according to quality management system ISO 9001:2008 and environmental management system ISO 14001. These XXX strictly aim at delivering top-quality products. The institutes TÜV Rheinland and the Netherland MRPI are responsible for monitoring these quality systems.
We continuously strive to improve our production processes and focus on material waste and saving energy.
Having these quality measures in place, brings confidence to our products and allows us the opportunity to offer product guarantees to the end users.
