The Material RHEINZINK

RHEINZINK is a trade name for titanium zinc, manufactured to DIN EN 988. Electrolytically refined zinc with a 99.995% degree of purity as defined by DIN EN 1179 serves as the basis for the alloy, which also includes small yet precise amounts of copper and titanium. The composition of the alloy is one of the factors determining the technological properties of the material – as well as the colour of the RHEINZINK patina.

The raw material is melted, cast and wound onto a steel sleeve in a single continuous operation. The quality of this material is uniform and flawless. These coils are then used for further processing as a universal source material to produce RHEINZINK's high-quality roof drainage programme, pre-fabricated parts for roofing applications and facade cladding including the necessary building profiles.

RHEINZINK is available in four different Product Lines: RHEINZINK-PATINA, PROTECT, COLOR and INTERIEUR.

The RHEINZINK Stamp

Product Marking

European standards stipulate that products are marked by the manufacturer. Our RHEINZINK products are identified as follows to prove they are the genuine article.

  • RHEINZINK sheets and coils with a continuous coloured stamp on the underside of the metal.
  • Guttering and downpipes: continuous embossed stamp.
  • Accessories for roof drainage: embossed stamp.
  • Pallets containing roof drainage products: stickers applied to the packaging, incl. detailed product data.

The RHEINZINK embossed stamp shown on our roof drainage products is an important mark of quality. This system includes almost 500 different parts, which are all matched in terms of dimensions, so guaranteeing a perfect fit.

Quality

  • DIN ISO 9001:2008 certified
  • DIN ISO 14001:2004 certified
  • DIN EN 16001:2009 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.

All RHEINZINK products are certified to DIN EN ISO 9001:2008 and submitted for voluntary inspection by TÜV Rheinland according to the stringent requirements of the QUALITY ZINC Criteria Catalogue. This recognised German certification company has developed its own quality label for zinc as a building material. A catalogue 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).

Environmentally conscious handling is documented through the adoption of ISO 14001:2004, the Environmental Management System, tested and certified by the TÜV Rheinland. Finally our environmental consciousness is also proved by the implementation of our energy management system according to DIN EN 16001. We are fully committed to save energy and resources thus minimalising our products effects on the environment.

Decalaration

Product Declaration

Regulations governing building products / CE marking

The products manufactured by RHEINZINK according to harmonised standards always comply with the requirements of the building products regulations for the CE marking of products used for construction.

We automatically supply customers with a declaration of performance and CE mark on delivery of the relevant product. This forms part of the shipping documents. Should you also be interested in receiving these documents electronically, please get in touch with us.

In the case of semi-finished products / sheets / coils (DIN EN 988) and our roof drainage programme (DIN EN 612), CE marking is not possible according to the building products regulations as these standards are not harmonised.

This however has no influence on product quality: All products manufactured by ourselves satisfy the relevant product standard. In addition, our semi-finished products are subject to the stringent QUALITY ZINC criteria, which are monitored by TÜV Rheinland.

REACH Regulation EC/1907/2006

In Europe all substances manufactured in a volume > 1 t/year must be registered according to the REACH Regulation EC/1907/2006. Furthermore, Art. 33 of the regulation states that manufacturers of products containing so-called substances of very high concern (SVHC) as defined by Art. 57 ff. / Annex XIV of the regulation in a concentration > 0.1% are obliged to notify customers accordingly and to supply them with information about the safe use of such products.

For RHEINZINK products this means:

  • RHEINZINK products are not subject to the obligation of registration under this regulation as they are not substances but products.
  • Our suppliers of raw materials have already preregistered their substances covered by the REACH Regulation and will carry out registration by the deadline.
  • As RHEINZINK products do not contain SVHC in concentrations > 0.1%, they do not need to be registered.

Our REACH declaration can be found under Downloads.

Environmental Product Declaration according to SO 14025 Type III and EN 15804

The certification of buildings according to sustainability criteria is becoming increasingly important. Verified product data from product-specific declarations or general databases are used by different certification systems such as DGNB, LEED or BREAM to access environmental performance of buildings. In this context we rely on transparency and real data and there for possess Environmental Product Declarations in accordance with ISO 14025 Type III and EN 15804 for our product Lines PATINA , PROTECT and INTERIEUR.
