What is the U-bolt surface technology? As one of the most commonly used fasteners, U-bolts require long-term maintenance during their use because of their importance. But maintenance is just one of the methods, the other is to pay more attention to the process of bolt surface. We don't know much about the surface technology of bolts, so next, Plit Fasteners will explain the surface technology of bolts.
One of the most effective methods for U-bolts is galvanizing. Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metals, alloys or other materials to play a role of beauty and rust prevention. The main method used is hot-dip galvanizing.
The national standard of hot-dip galvanizing is GB / T13912-2002 "Technical requirements and test methods for hot-dip galvanizing of metal-clad iron and steel parts." The metal after galvanizing should be smooth, free of zinc knobs, burrs, and silver-white The thickness is controllable and can be chosen arbitrarily within 5-107um; the surface has no hydrogen embrittlement and no temperature hazard, which can ensure the mechanical properties of the material remain unchanged; it can replace some of the processes that require hot galvanizing; the corrosion resistance of the metal after galvanizing Good performance, neutral salt spray test for 240 hours.
Galvanized has a wide range of applications, such as steel nails, iron nails, fasteners, various metal pipe fittings, scaffolding fasteners, and so on.
