Korean pressed couplers are manufactured in various standard types to accommodate multiple scaffolding configurations:
- Double Couplers: Fixed clamps joining two tubes at right angles, manufactured from forged steel with hot-dip galvanized or electro-galvanized coatings for enhanced protection.
- Swivel Couplers: Enable angular connections to support diagonal bracing and complex scaffold geometries, designed for strength and flexibility.
- Putlog Couplers: Connect ledger tubes to transoms and support working platforms.
- Half Couplers: Attach tubes to structures or form cantilever scaffolding configurations.
- Sleeve Couplers: Used for end-to-end tube connections allowing extension, secured with mechanical pressing.
Standard tube fitting diameters include 48.3mm with M14 bolts offering secure locking. Korean pressed couplers emphasize dimensional accuracy and high tensile strength to meet safety requirements.
Surface finishing is a key quality aspect. Common Korean finishing methods include:
- Hot-dip galvanizing: providing thick zinc layers for extreme corrosion resistance.
- Electro-galvanizing: offering uniform zinc plating for lighter applications.
- In some cases, powder coating enhances chemical resistance and aesthetics.
These finishes ensure long service life even in coastal or industrial climates.
In addition to traditional finishings, Korean manufacturers are experimenting with advanced coatings such as zinc-aluminum alloys and nano-ceramic layers to further improve durability and environmental resistance.
