Scaffolding Coupler and Scaffolds

Scaffolding is used for construction support, framing, or concrete shoring. The fundamental parts of scaffolding include scaffolding standards, scaffold ledgers, scaffold braces, scaffold transoms, scaffold jack base, scaffold boards, scaffold ladders, and scaffold beams.

There are two main types of scaffolding: tube and coupler scaffold and system scaffold.

Tube and Coupler Scaffold

Tube and coupler scaffold is also called pipe and clamp scaffolding, tube scaffolding, or tube and fitting scaffold. It is formed and installed by scaffolding tubes and scaffolding couplers.

The scaffold couplers joint scaffolding pipes in the tube and coupler system scaffold construction. They help scaffolding pipes form the main parts of scaffolding: scaffold vertical standards, horizontal ledgers, diagonal braces, transoms and scaffold staging, scaffold side protection, etc.  Meanwhile, in the pipe and clamp system, you can use 2.4mm, 3.2mm, and 4.0mm thickness of scaffolding pipes to form a light weight and heavy-duty scaffolding.

The interval of the tube and coupler scaffold is customized at any distance as long as follows up the scaffold and construction safety rules.

Scaffolding couplers are also called scaffolding clamps or scaffold fittings. It is the scaffold joints and connectors of the tube and clamp scaffold system. They are used to fix the scaffold tubes, scaffold boards, scaffold ladders, and scaffold beams in position in the scaffolding construction.

According to the scaffolding coupler function in the tubular scaffolding, there are different types of scaffold couplers: scaffold double coupler(right angle coupler), scaffold swivel coupler, scaffold single(putlog) coupler, scaffold sleeve coupler, scaffold joint pins, scaffold beam clamp, scaffold ladder clamp, scaffold board retaining coupler, scaffold limpet plank clamps, toe board clips, and scaffold fence clamps, etc.

Tube and Coupler scaffolding is the best type of scaffold:

    1. Heavy Duty Load with Up to 4.0mm Thick Scaffold Parts.
    2. Customized Intervals
    3. Scaffolding Couplers are the Most Durable
    4. Flexible to Form All Shapes of Scaffold for Construction
    5. Durable with Galvanized Finishing
    6. Cheap In Cost Then System Scaffold
    7. Easy Transporation and Stock

System Scaffold

System scaffold is also called modular scaffolds. It is another scaffold other than the tube and coupler scaffold.  System scaffolds include prefabricated modular scaffold parts and components of standards, ledgers, braces, boards, etc.
There are 6 types of modular system scaffolds:

    1. Ringlock Scaffolding System
    2. Kwikstage Scaffolding System
    3. Cuplock Scaffolding System
    4. Scaffolding Frames
    5. Crab Scaffolding System
    6. Quick Lock Scaffolding System

Main Types of Scaffolding Coupling

The 5 main types of scaffold coupling include:

      1. Scaffold Double Coupler
      2. Scaffold Swivel Coupler
      3. Scaffold Putlog Coupler(Single Coupler)

Drop Forged, Pressed, and Casted Type of Scaffolding Couplers

According to the scaffolding manufacturer procedure, you can find the following different types of scaffolding couplers:

Drop Forged Scaffolding Couplers and Photos

Forged scaffolding couplers are drop forged from steel round bars. Before the forging, need to heat the round bar to make it easy for forging. The Steel round bar for forged couplers should be of high strength and less hardness.

Forged scaffolding couplers are the best scaffolding coupler among all of the three types of scaffold clamps. You can have forged couplers of the double coupler, swivel clamp, girder coupler, putlog, board clamps, etc.

Drop forged scaffold fittings are the most common type among all three types of scaffold clamps. You can find forged clamps with forged covers or forged bases.  Most scaffolding companies, construction companies, and formwork companies in global wide are using drop-forged scaffolding couplers.

Pressed Steel Scaffolding Couplers and Photos

Pressed Steel Scaffolding Couplers are manufactured from high-strength steel plates. Punching, Forming, and assembly by bolt and nut. You can find both British type and Japanese/Korean type pressed steel scaffold couplers in Wellmade. While sleeve couplers are always pressed steel type. There are no drop forged sleeve couplers.  Meanwhile Japanese standard pressed steel scaffold couplers are used for OD48.6mm scaffolding pipes JIS standard.

Cast Iron Scaffolding Couplers and Photos

Cast iron scaffolding couplers are traditional Chinese standard scaffold couplers. It is cheaper than drop forged or pressed steel scaffold fittings. Some countries like Ethiopia and Bangladesh prefer cast iron scaffold couplers for your project.

Different Scaffolding Coupler Sizes

There are different sizes for scaffolding couplers. According to the pipe diameter used for scaffolding. You can find the following tube and scaffold coupler sizes:

      • OD48mm
      • OD42mm
      • OD60mm
      • OD76mm
      • OD89mm

48mm is the standard pipe size. Thus 48mm scaffolding coupler size is the most popular. More than standard 48mm scaffolding couplers, other sizes are specially designed for light-duty and heavy-duty construction scaffold systems.

42mm size scaffold couplers are used to connect two frame poles. Because traditional scaffolding frame vertical parts are always 42mm in diameter.

60mm and 76mm size scaffold couplers are also called prop couplers. They are used to connect two scaffolding props in the shoring scaffold system. 60mm size scaffolding clamps are also connectors between heavy-duty shoring system scaffolds. Like shoring frames, hi load ring shore system, etc.

89mm sizes scaffolding couplers are used for New York City Sidewalk Sheild Construction. The large scaffold couplers connect bridge legs which are heavy-duty scaffolding posts with 89mm diameters. You can find the following different types of OD89mm scaffold clamps. The OD89mm

Standard Class for Forged and Pressed Scaffold Couplers

In BS1139 and EN74 standards, you can find 2 classes of scaffolding couplers. Include

  • Class A Scaffolding Coupler
  • Class B Scaffolding Coupler

Basically, Class A is lighter duty than Class B scaffold couplers in weight-bearing. Class B scaffold coupler allows more load(KN). For construction design, most companies ask Class B for double couplers. While for swivel couplers, Class A is acceptable.

Hot Dip Galvanized VS E-galvanized Couplers

For scaffold couplers, you can ask hot-dip galvanized or E-galvanized(zinc-plated) finishing.
E-galvanized is called cold galvanized or zinc plated. It is with less zinc and not as durable as hot dip galvanized. But it is much cheaper in price.
Hot dip galvanized couplers are the most durable scaffolding couplers. Industrial construction projects especially oil gas offshore and marine projects are required hot dip galvanized scaffolding couplers mostly. The zinc thickness for the hot-dip galvanized scaffolding couplers are more than 40 micros. More than the zinc thickness, Wellmade does adhere to test galvanizing quality for both zinc-plated and hot-dip galvanized scaffolding couplers according to CE requirements.  Our scaffolding coupler durability is more than normal scaffold factories.

Scaffolding Coupler Slip and Distortion Test

Wellmade has its own test facilities. We do daily slip and distortion tests for all of the scaffolding couplers during production.  Following are the test videos.
