Former Rolling Mill at Treforest Tinplate Works

A long rubble stone range, the eaves raised in brick and with a corrugated asbestos-cement roof with strip glazing and raised ridge ventilator. The S gable end has 3 round-headed doorways, the central having a keystone dated 1835. Above are 3 stepped bullseye vents. The E wall has round-headed openings alternating with round vents with inserted brickwork. The central bays have 4 smaller doorways between wider doorways. The N gable end has 3 stepped bullseye vents in the gable and 3 doorways below, of which the L-hand doorway has brick dressings and represents the widening of the building. The other 2 doorways and the vents have stone dressings.

The W wall, facing the feeder, is of 33 bays all now infilled, mainly of tall round-headed doorways but 7 openings have sills placed opposite sluice gates in the feeder, through which iron launders brought water into the building for the waterwheels. The wall also incorporates 3 evenly-placed wider doorways.

Not accessible at the time of inspection.
