Pipe connectors malleable cast iron – hot-dip galvanised

Pipe connectors in malleable cast iron, hot-dip galvanised and electro-galvanised

The load-bearing range for railing construction: pipe connectors in malleable cast iron to ASTM A197, hot-dip galvanised to ASTM A153 and additionally electro-galvanised. Every fitting comes with a clamping screw in V2A stainless steel that will not seize up even after years outdoors.

Why malleable cast iron

Malleable cast iron has a tough structure: it does not fracture in a brittle way but deforms visibly under overload before it fails. In a component that holds fall protection together, that is precisely the difference between advance warning and sudden failure.

TÜV type-tested

The entire range is type-tested by TÜV Rheinland (test report no. 17704961 001). With every item you will find the permissible bending moment and the permissible dismantling force under “Technical data” – both values already include the safety factor of 2,0. Details on the page TÜV testing and material.

Available sizes

For tube outside diameters of 21,3 mm, 26,9 mm, 33,7 mm, 42,4 mm, 48,3 mm and 60,3 mm. The standard in railing construction is Ø 42,4 mm.

How this differs from the stainless steel range

Malleable cast iron is clamped – push the tube in, tighten the screw, done, and it can be dismantled again at any time. The V2A stainless steel pipe connectors, by contrast, are push-fitted and bonded and stay bright; the TÜV load values do not apply to them.
