Wellmade Japanese and Korean Scaffolding Clamps
Wellmade’s JIS and Korean standard scaffolding are tested according to JIS A 8951 and KSD 3501.
There are OD48.6mm standard JIS and Korean standard scaffolding clamps in Wellmade, also other sizes like OD42mm and OD60mm.
For anti-corrosion purpose, the JIS and Korean standard scaffolding clamps are always galvanized.
There are 2 types of galvanizing for the JIS and Korean standard clamps:
- Zinc-plated
- Hot Dip Galvanized
Zinc-plated JIS and Korean standard scaffolding clamps are the most common couplers. It is always finished in golden color(yellow). If you want, white color zinc-plated scaffolding clamps are available too.
Hot dip galvanized scaffolding clamps are the most durable without rusty for 15-20 years. The color is always white or grey.
Zinc-plated is also called E-galvanized. Compare to hot dip galvanizing, E-gal couplers are easy to rust within 0.5-2 years depending on the construction site and stock conditions.
