The Pruszyński Company guarantees that each individual order will be produced in the same color (shade). However, due to the complexity of the coating processes, slight variations in shade may occur between individual shipments.
Accordingly, liability for color is limited to a single shipment.
Therefore, when reordering sheet metal for a specific batch, please be sure to indicate on the order form or inform your sales representative that this is a follow-up order and to provide a color sample.
To ensure color consistency between sandwich panels and other components, such as flashings, they should be ordered from a single supplier.

For gutters made of Titan-zinc or with a titanium additive, the gutters are joined by soldering.
