REXWAY conduit boxes are custom manufactured from malleable iron. Malleable iron after casting is subjected to annealing which is a controlled heating and cooling exercise – among other reactions, this process removes carbon from the casting. It is the presence of carbon in cast iron which causes its brittleness and removing an amount makes the casting stronger or more “malleable”

Malleable and cast iron look very similar, thus the choice between malleable and cast iron is often based on economy rather than properties. In the application of conduit fittings it is important that they do not crack when faced with any external impact because it will compromise the entire cable management systems grounding conductor and EMI shielding capabilities as well as leave the encased circuit damaged or exposed.

REXWAY malleable cast iron conduit boxes have many distinct advantages:
– Fittings retain good impact resistance, even at low temperatures, and
– Fittings possess high wear resistanc

After casting, annealing and cooling, REXWAY conduit boxes are hot dipped galvanised in a molten zinc bath. HDG is widely regarded as offering the most superior of corrosion protection available because the zinc coating is very difficult to compromise.

The strictest quality control ensures REXWAY malleable cast iron conduit boxes are all precision threaded. This ensures a straight continuous conduit line. The perpendicular thread finish also facilitates minimum installation times.
