Standardized titanium fasteners supplied in accordance with standards DIN-EN-ISO, DIN-EN-ISO, DIN and also BSI, BSW.
Standardized and non-standard construction fasteners, anchors and fasteners for bridge, mining and steel structures, telecommunication towers, observation towers, railway ballast, solar power, etc.
Standardized and non-standard fasteners and fasteners for the woodworking industry, wood and plasterboard construction, manufacturer of plastic windows, timber, joiners, carpenters, flooring and furniture.
Standard and non-standard rivets, welding screws, compression screws and bridges, inserts for plastics and rubber, security screws, threaded inserts and housings, including the installation and application of tools, etc.
Special fasteners for mining, power, chemical, petrochemical and heavy engineering. Partners are granted a complete service including technical guidance, documentation, necessary testing, which are documented by issuing the relevant certificate, etc.
Drawn parts are supplied according to customer’s drawings. In case the customer does not have its own design and technological background, we can arrange technical delivery service as the material itself, including complete technical documentation to the actual fastener.
Technological processes in the manufacture of parts of the drawing are particularly cold forming, hot chip and conventional CNC machining, pressing the single or sequential molding tools, stamping, etc., followed by heat treatment. The steel products are neutral, isothermal, bainite, thermal, and dual induction quenching, then tempering, annealing, with a reduction in internal stress, normalization, ion implantation. U-corrosive materials and precipitation hardening.
Other material is delivered within Kanban supply. That is primarily packaging, welding, small electronics, rubber and plastic material, labour and technical aids, adhesives, tools, instruments, hydraulic and pneumatic couplings, fittings and hoses, abrasive consumables, lubricants and preservatives.
Surface finishing: fully in accordance with CSN EN ISO 4042:1999, EN ISO 10683:2000 and the European Directive EU2002/95/EC valid from 1.7.2006 prohibiting the use of CH6 (hexavalent chromium), Cd (cadmium) for the surface treatment of metals, we provide state of the art coating on the material supplied by us. That is primarily finishing non-elecrolitically eliminated by coating with zinc mikrolamelam technology DELTA MKS, Delta Protect, DELTA Seal, Geomet, which gradually replaces the first form of the modern surface adjustments Dacromet.
Furthermore, electroplating and hot dip galvanizing, nickel, veralizace, chrome, brass, copper plated, silver plated, gold plating, anodizing, burnishing, phosphate, Sursulf, Oxinit and their combinations Arcor etc. Most finishing can then further improve the corrosion resistance and facilitate the application itself. During mounting, an impregnation, which closes the pores in the very finish. This paint stripper can be either completely dry, or conversely may include lubricating grease. Impregnation is colourless.
Locking and sealing systems like TufLok and Eslok facilitating large-scale assembly guarantee high security connections against loosening under vibration. Sealants protect the screw joint against leakage of fluid between themselves threaded blades, which eliminates internal corrosion of joints and thus guarantees its long-term disassembled. The application of these cements is accomplished by applying the appropriate layers to the bolt threads, by automatic technological process that ensures the application of the sealant in exact proportion.
