Quality marks
Woodies® Ultimate screws have been thoroughly tested and approved so that you, as the user, are assured ultimate satisfaction in your screw applications. See below for more information on our quality marks.
European Technical Assessment (ETA)
Woodies® Ultimate ETA/CE quality mark
Woodies® Ultimate galvanized screws come with ETA/CE certification. In other words, these screws comply with the strictest European standards, allowing them to be used for construction purposes.ropese normen, waardoor ze constructief gebruikt mogen worden.
The European Technical Assessment (ETA) is a document containing information on the performance of a given construction product and its essential characteristics. The ETA is officially defined in the EU Construction Products Regulation (EU/305/2011), which came into effect for all EU member states on 1 July 2013.
The ETA forms the basis of a declaration of performance (DoP), to be drawn up by the manufacturer.
The ETA helps to build trust in the performance of a given product with regard to its essential features, on the basis of its intended use. The ETA trajectory supports the free movement of construction products and, as a result, the European internal market as well
To ensure these standards and – above all – the quality of the products, our screws undergo thorough quality testing. Not only do we carry out tests at the manufacturing site, but also at our own Academy in Lelystad. This test facility is fitted with professional test equipment, which is used to test various properties of the screws, such as grip point, breaking point and drill speed in both soft and hard wood.
Protected in a special EP5 coating
Woodies® Ultimate C4 quality mark
Shield Outdoor (Blackline) screws are C4-certified. This means that they meet the highest standard of corrosion protection. These Woodies® Ultimate screws have a special corrosion-resistant EP5 coating, thanks to which the Shield Outdoor screws are many times stronger and more resistant than, for example, stainless steel screws.
Salt spray test
This commonly applied test method assesses the corrosion resistance of screws by subjecting them to a continuous spray of saline solution. The chart below compares the performance of the corrosion-resistance coating of Woodies® Ultimate Shield Outdoor screws against the corrosion resistance performance of a range of coated stainless steel screws. Findings: Shield Outdoor (Blackline) screws pass this salt spray test for up to 2,000 hours.
Rigorously tested
Woodies® Ultimate SHR quality mark
Woodies® Ultimate screws have the SHR quality mark.
The SHR wood research foundation conducts independent tests in its laboratories. The following properties are tested: pull-out resistance, pull-through resistance, screwing-in torque and flexural strength. At least once a year, SHR carries out spot checks to ascertain whether the screws still have the right properties.
