HS 7604 HS 7604 — aluminium bars, rods and profiles (7604.21 hollow / 7604.29 other alloy profiles); heading follows closed chambers on the die
A greenhouse frame is a family of sections, not a single bar: the glazing bead holds the pane, the gutter takes the rain, the ridge closes the roof, the sash moves, the base rail sits on the ground, the cover hides the joint. We supply the family as Turkish-origin extruded aluminium — mill, anodised or powder-coated — cut to your list. Send a drawing or a full bill of materials; mass per metre is quoted from the die, not guessed on this page.
