Hot dip galvanizing hdg delivers long term maintenance free corrosion protection of fasteners thus eliminating the concern. Hot dip galvanizing provides uniform coatings on these surfaces because the process develops the zinc coating by way of a metallurgical reaction. Hot dip galvanizing hdg is one of the oldest and most commenly used method of protecting steel fasteners from corrosion. Hdg coating is relatively maintainence free and provides excellent corrosion protection to steel structures for 50 70 years in most atmospheric environments industrial urban marine rural. Hot dip galvanizing produces a zinc coating with a measurable.
To avoid mismatched bolts and nuts that cause installation issues like bad fit. Hot dipped galvanized screws 117 products found. Hot dip galvanizing the coating process involves completely immersing the bolts in a tank containing 70 tons of 840 f molten zinc. The protection of fasteners is imperative because if the fasteners corrode and fail the integrity of the structure is at risk. This time varies depending on the diameter steel grade and a number of other factors.
The material will remain in the tank until the zinc has metallurgically bonded to the steel. The fasteners are dipped in a bath of molten zinc with normal temperatures around 455 c to 480 c and high temperatures between 530 c and 560 c. Whether used in atmospheric concrete soil or water fresh or salt applications hot dip galvanized steel provides maximum time to first maintenance. Our hot dip galvanized fasteners are made of high quality raw materials like stainless steel alloy steel nickel alloy and non ferrous materials. High tensile fasteners like b7 2h grade 8 8 10 9 12 9 fasteners are commonly hot dipped galvanized.
