Marley Alutec has added an aluminium box profile gutter and square 72mm Flush-fit downpipe
to its Alutec Evolve range
The company says the Evolve box system can deal with a maximum flow rate of seven litres per second, which the firm says reduces the number of downpipes required.
The box profile features concealed, top-fixing brackets. The box profile is compatible with the other square and circular traditional downpipes, which are available in 20 standard colours.
