Continuous quality control is maintained at all stages of production. We also regularly conduct strength tests on finished products in accordance with EN 13377-2002. For this purpose, we purchased a test rig that is unique in Russia. On this rig, we break every 10,000th beam produced at the factory to monitor and confirm specified characteristics. When you purchase H20 Karelia Premium, you can be assured of the highest quality. This applies to both the technical specifications and the appearance of the finished product.
