Type of Scaffolding Fixed clamps
British forged fixed clamp is also called BS1139 standard scaffolding double coupler. It is right angle clamps with 21mm cross nut&washer. BS1139 fixed clamps are most used by global countries.
Germany type scaffold fixed clamps are with 22mm flange nut. It is anti slip designed in 1.25KG weight. Both round threaded(Layher heavy duty type) and normal threaded bolts are available.
USA I Bolt fixed clamps is in 1.5KG. It is with 22mm flange nut too. The I bolt scaffolding fixed clamps size for scaffolding include O.D42mm, O.D48.3mm, O.D60mm, and O.D 89mm.
Australian type fixed clamp scaffolding are fabricated with 23mm flange nut. There are lightweight and heavyweight Australian fixed and swivel clamps.
British pressed fixed clamp is also called pressed 90 degree or right angle coupler. It is in 0.85KG and used as 3.2mm scaffold tube fittings.
JIS 3444 standard is Japanese scaffolding clamp standard. It is able to fix scaffolding poles and pipes from O.D 42mm to O.D 48.6mm.
Different from Japanese standard pressed fixed clamp, Korean scaffold fixed clamps is used to fix O.D 48.6mm scaffolding pipes in construction.
Italian type right angle coupler is pressed steel too. It is specially used by the Italian scaffolding construction companies.
Fixed wedge clamps are scaffold fittings between aluminum scaffold tubes. It is another type of the USA scaffolding fixed clamps.
Fixed Clamp Scaffolding Sizes
O.D 48.3mm scaffold fixed clamps are the most popular sizes in the tube and clamp scaffolding construction. It is also called 1.5” scaffolding right angle clamps or 50mm scaffold double couplers.
89mm scaffolding fixed and swivel clamps to the USA American heavy duty type scaffold fittings O.D 42mm Scaffolding Fixed Clamps
Traditional scaffolding frames verticals are in O.D 42mm (41.3-42.7mm). O.D42mm scaffold fixed clamps are used to connect 42mm scaffolding poles. Both Japanese standards fixed clamps and forged fixed clamps are able to be used to fix the O.D 42mm scaffold poles.
- O.D 60mm Scaffolding Fixed Clamps
There are O.D 48mmx60mm, O.D 42mmx60mm scaffolding fixed clamp for your construction. It is used to fix the 2” scaffolding poles like adjustable steel props and 2” scaffold tubes etc.
- O.D 76mm scaffolding fixed clamps
O.D 76mm scaffolding fixed clamps are called prop coupler or shoring civil clamps. It is used to connect between heavy-duty scaffold post shore jacks with O.D 76mm outer tubes.
- O.D 89mm scaffolding fixed clamps
O.D 89mm scaffold fixed clamps mainly required by the New York scaffolding and construction companies. It is used in the city sidewalk scaffolding system. Used to fix between the sidewalk shield bridge legs and posts.

Zinc Plated VS Hot Dip Galvanizing Scaffolding Fixed Clamps
Hot-dip galvanized fixed clamp is the most durable scaffolding fittings finishing. The zinc thickness of the HDG fixed clamps is more than 40 micros.
HDG fixed clamps are required by oil gas companies for onshore and offshore construction. It is also required by the scaffolding rental companies for long-term recycling using.
You can use the hot-dip galvanized fixed clamps in all weather and under all atmospheres & conditions.
Zinc plated fixed clamps are also called E-galvanized scaffolding couplers. According to its colour, there are white zinc plated and golden galvanizing.
zinc plated scaffolding fixed clamps are required by a wide range of scaffolding and construction companies. It is because of the less cost.
Zinc plated fixed clamps are not as good as Hot dip galvanized in corrosion resistance.
Scaffolding Clamps Types
More than the forged and pressed type scaffolding fixed clamps, you can find all other scaffolding clamps in Wellmade. All of the scaffold couplers are tested according to the international scaffolding standards.
Wellmade manufactures the scaffold fittings according to ISO9001 management. In each batch of scaffolding clamp manufacturing, you can find the relative test report against your order and shipments.
