The term "Double standing seam" describes a type of lengthwise connection between adjacent sections above the water level. Double standing seams are fabricated in 25, 35 and 38mm heights, depending on roof slope and lengths. This connection is rainproof without applying any additional measure.
The edges of the sections can be formed by roll-former or by hand. The seams can be closed either with seaming machine or by hand.
It is characterized by its sharply defined lines and by its numerous detail variations.
