Mela dRain 540 - Technical specifications

profiling and installation


The continuous metal roofing system Mela_dRain 540 produces sheets of a length equal to the entire slope length.
The on-site direct profiling allows the production of sheets with a length that is not transportable:

• on the ground: the profiling machine, housed in a container, is brought to the construction site for the production of roofing sheets.

• at height: the container, equipped with a chain system, is hoisted alongside the slope for aerial profiling. This avoids difficult, dangerous, and costly handling for the high-altitude pulling of long roofing sheets.


Installation is simple, intuitive and quick:

Positioning of the first Mela_dRain 540 sheet with the ‘female’ profile facing outward.

Positioning and fastening of the dRain_Fix fixing bracket (on wooden batten or metal support).

Overlapping and interlocking the next sheet with a step.

Scientific safety

The choice of the Mela dRain 540 roofing system represents durability of the roofing membrane, low maintenance, and performance certainty. The performance guarantee of the Melathron roof is supported by tests, certifications, and technical reports that certify its complete safety.


Flooding tests of the roofing have been conducted at accredited certification authorities.
The results show total impermeability of the continuous membrane and drainage of infiltrations through the double overlying drainage channel.

Resistance to upward forces

The wind force has been tested with tests conducted using airbags on the intrados. The dRain_Fix steel bracket with its exclusive multiple attachment ensures exceptional resistance to depression (18 kN). Mela_dRain 540 has no rivals in terms of resistance to the force exerted by the wind.

Resistance to downward forces

Solicited by point and distributed loads, the Mela_dRain 540 roofing system reacts with extraordinary results, thanks also to the exclusive fastening system that provides total support of the roofing membrane to the supporting battens and insulation.
