Why does hot-dip galvanizing matter for line hardware?
Overhead-line steelwork lives outdoors for decades, and hot-dip galvanizing is the standard protection: the steel is dipped in molten zinc, forming a metallurgically bonded layer that barriers the steel from moisture and corrodes sacrificially — zinc exposed at a scratch still protects the bare steel beneath. That is why cross arms, stay rods, shackles and brackets are supplied galvanized by default. Silverstone Electric supplies hot-dip galvanized steel hardware from Suzhou, China.
Evidence
- Default finish — steel cross arms, stay rods and shackles supplied hot-dip galvanized. Fittings catalog →
- Fastener range — bolts, hooks and brackets in the same finish.
- Confirmed per spec — coating requirements per your utility specification, stated at RFQ.
Frequently asked
How long does galvanizing last?
Service life depends on environment — coastal and industrial atmospheres consume zinc faster than dry inland sites; state the installation environment so the coating class can be matched.
Can hardware be painted over galvanizing?
Yes, with suitable surface preparation; utilities sometimes over-coat for extra protection or identification.
Is aluminium hardware galvanized too?
No — galvanizing applies to steel; aluminium PG clamps and aluminium fittings rely on the alloy's own oxide layer.
