Our offer includes high-strength HV sets for preloaded connections compliant with the requirements of the harmonized standards EN 14399 and EN 1090-2.
The highest quality of ŁF sets results, among others, from the implemented and rigorously observed production process. The ERP system adapted to our needs assigns a unique number to each production batch. This allows 100% identification of our HV sets and easy access to detailed test results. The system also contains complete information about individual operations, status, and their start and end dates. Production is continuously monitored and data is archived.
We can also easily identify the steel grade and the heat number used to produce HV sets. The suppliers of wire rod are only renowned steel mills from Europe, guaranteeing that our quality requirements are met. This allows for the flawless execution of the heat treatment process – one of the most important processes for mechanical properties in the entire production of high-strength HV bolts. We conduct the process according to the CQI-9 standard. The hot-dip galvanizing process is carried out according to DSV-GAV standards and the ISO 10684 standard.
Our offer is complemented by comprehensive technical support in the design and assembly of steel structures.
