Holland Scaffold Supply | HSS | Segments

HSS | Tubes & Couplers

Holland Scaffold Supply supplies both aluminum and galvanized steel tubes for scaffolding and fall protection systems. All tubes have an outer diameter of Ø48.3 mm (1.9 inches) and wall thicknesses of 3.2 mm, 3.7 mm (schedule 40) or 4.0 mm, depending on the project specifications. Other diameters and wall thicknesses are available on request.

Aluminum tubes are manufactured from EN-AW 6061 T6, 6060 T66, or 6082 T6 alloys, which are known for their excellent balance of strength, corrosion resistance, and lightweight, with a tensile strength of 260–310 MPa and a yield strength of 240 MPa. Steel tubes are produced from high-strength structural steel S235GT Type 4, a low-alloy material with a tensile strength of more than 400 MPa and a yield strength of 235 MPa. Steel tubes are hot-dip galvanized (60 microns) for long-lasting corrosion protection. Each tube and coupler is 100% traceable by lot number and comes with a material test certificate in accordance with EN 10204-3.1.

Holland Scaffold Supply's right-angle and swivel couplers are designed for precision, durability and consistent performance. Each coupler consists of components made of carefully selected materials:

• Body and wedges – manufactured from EN S355MC (1.0976), a thermomechanically hot-rolled fine-grained structural steel with a minimum yield strength of 355 MPa, designed for cold forming operations such as bending and folding. This material provides superior strength, formability and impact resistance for demanding scaffolding structures.
• Wire – manufactured from EN S235JRC+C (1.0122) cold-drawn bars, providing improved dimensional accuracy, a glossy surface and a uniform microstructure. Its excellent weldability and bending performance (180° flat bending without cracking) make it ideal for the production of couplers.

Each coupler is hot-dip galvanized according to NEN-EN-ISO 1461:2009, which provides long-term protection against corrosion. This ensures that our couplers maintain their integrity and strength even under harsh environmental conditions such as coastal areas or industrial sites.
