Japanese and Korean Scaffolding Clamps

Japanese standard scaffolding clamps are also called JIS scaffold clamps.  It is manufactured according to JIS A 8951 standard. In construction, the JIS scaffolding standard scaffolding clamps are used to fix JIS 3444 standard scaffolding pipes. Korean standard scaffolding clamps are similar to Japanese standard scaffolding clamps in weight, steel, specifications, etc.

Standard JIS and Korean scaffolding clamps are used to fix OD48.6mm scaffolding pipes. While JIS scaffolding clamps, with special 110-degree clamp bases, can be used to connect two scaffolding frame verticals. Which is in OD42mm.

The JIS and Korean standard scaffold fittings include different types of scaffold couplers including fixed clamps, swivel clamps, fixed beam clamps and swivel beam clamps (scaffold C clamp), inner joint pins, limpet clamps, half single clamps(checking clamp) and base plates, etc.

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:

  1. Zinc-plated
  2. 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.

JIS, Korean and Other Standard Scaffolding Couplers

JIS and Korean standard scaffolding clamps are lightweight compared to British, Germany, and USA standard scaffolding couplers. Use scaffold fix clamp for an example, you can find the different weights of different standards of scaffolding couplers.

JIS Double Clamps0.64 KG
Korean Double Couplers0.65 KG
British Double Coupler1.02KG
USA Double Coupler1.45 KG
Germany Double Coupler1.30 KG
Astralian Double Coupler1.05 KG

Both JIS and Korean standard scaffolding clamps are used to connect OD48.6mm scaffolding pipes. While other standard scaffold couplers, including EN 74, BS1139, and AS1576 standards scaffolding couplers are used to connect with standard OD48.3mm scaffold tubes.
