JMBS 3000 STANDING SEAM
JMBS 3000 is a double lock standing seam system using electric seamer.
Site roll forming enables single length sheet from ridge to eave without over lapping.
Movable clips fixed on purlins take care of heat expansion/contraction.
Depth 76mm achieves faster water shedding.
Two stiffening ribs at the centre give more strength to the sheet.
