HDG hot dip galvanized Thread Bar
Yidao thread bar is hot rolled continuous threaded along entire length, it can be cut short or extension with coupler at any point,
High tensile strength thread bar is easy handing in job sites for formwork ties, reinforcing coupling, soil nails, micropiles, soil and rock bolts, anchorage systems for mining, tunneling and post tensioning system.
Hot dip galvanized is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F).
A hot-dip galvanized coating is relatively easier and cheaper to specify than an organic paint coating of equivalent corrosion protection performance.
The British, European and International standard for hot-dip galvanizing is BS EN ISO 1461, which specifies a minimum coating thickness to be applied to steel in relation to the steels section thickness e.g. a steel fabrication with a section size thicker than 6 mm shall have a minimum galvanized coating thickness of 85 μm.
