Professional FAQ—Galvanize Washer Technology
Galvanize washer is typically manufactured from carbon steel (Q235) or stainless steel (A2/SS304, A4/SS316) substrates. Carbon steel variants are commonly used for general construction, while stainless steel provides enhanced corrosion resistance for marine and chemical environments. See engineeringtoolbox.com.
The most widely used coatings are hot-dip galvanizing (HDG) and electro-galvanizing. HDG provides thicker, more robust zinc layers (~40–70μm) ideal for exterior exposure, while electro-galvanized washers (zinc-plated) are suited for indoor applications. Reference: Corrosionpedia.
Thickness ranges from 1mm to 5mm, depending on load requirements, bolt diameter, and installation standards. For heavy structures and seismic categories, thicker washers are mandated. See Structure Magazine.
Sealing washers, often integrating elastomeric or neoprene layers, are designed to prevent fluid or gas leakage at bolt joints. In galvanize washer assemblies, they provide both electrical insulation and watertight performance. More at Engineers Edge.
Look for ISO 9001, CE Marking, and compliance with EN ISO 1461 (for galvanizing), ASTM F436/F844, and RoHS/REACH standards. Reliable suppliers offer third-party test reports.
Pricing fluctuates based on diameter, thickness, material, surface finish, and purchase volume. For example, a standard M10 HDG washer ranges from USD 0.014 to 0.022/pc. Bulk orders and OEM customization can reduce cost. Inquiry at mark@gardepota.com.
"Nut bolt washer" usually means a steel washer used with steel bolts/nuts. "SS nut bolt washer" refers specifically to stainless steel, offering enhanced corrosion resistance for chemical, marine, and food processing applications. For more, see AZoM.
