Gutters

Inner gutters are usually made of stainless steel plates and have a long service life. Generally, their thickness is 1.2-1.5mm due to welding requirements.

Suspended gutters are usually made of color steel plates. Certain architectural effect can be achieved when different colors are selected. When the outside height of Lysaght^? overflow gutters is lower than their inside height, the outward drainage of rainwater will be facilitated.

Fire partitions

The metal materials in both inner and outer sides of Lysaght^? systems are incombustible. Non-combustion-supporting thermal insulation materials are used inside the systems. For special fire prevention requirements, fire-proof cover plates, such as gypsum boards, reinforced fiber cement boards and fire-proof boards, can be set on top of thermal insulation layers to improve the fire-proof performance of buildings.

Lightning protection

The metal panel roof can be used as an air termination system. The connection between panels keeps electrical conduction. The thickness shall not be less than: 0. 5mm for stainless steel, hot-galvanized steel and copper plates, 0.65mm for aluminium plates and 0.7mm for iron-zinc plates.
