Owners of private gardens, developers, architects, timber shop owner, landscaping architects, owners of vineyards and orchards, members of planning committees and decision-makers – all of them make high demands when deciding on and purchasing preservative treated wooden products. Preservative treated wooden products, marked with the RAL Quality Label for preservative treated wood construction elements fulfill your demands – long service life, safety and ease of maintenance. In the following we outline the underlying concept of RAL Quality Control for timber products.

  • What the Quality Control system consists of,
  • What relevant measures are taken during production,
  • How you can distinguish RAL wood products from others,
  • And finally the specific benefits for you and your business by using timber certified by RAL Quality scheme

One particular benefit when using products marked with the RAL Quality Label is the 10-year manufacturer’s warranty.

The Quality Label – how to recognize it and what it stands for

RAL quality-controlled wood products can be identified very easily by durable product-markings, e.g. by a plaque with the RAL quality mark, referencing the year of production year and other details provided by the manufacturer.

A further way of indicating RAL products is the “Simple Label”, by use of three stylized palisades, combined with the letter-sequence RAL and the manufacturer’s code number. This simplified quality mark is applied in several variations, e.g. as a marker nail or clip, by marking iron, by embossing or similar methods providing a durable marking on the wooden element.

The RAL Quality Label stands for:

  • Use of untreated timber of high-quality as raw meterial
  • Use of officially authorized wood preservatives
  • Profound treatment according to the most update treatment technic, specification and treatment requirements
  • 10-year manufacturer’s warranty
  • Highest durability and performance of the timber products providing a maximum of safety for everybody
