Short answer:<\/strong> A greenhouse profile roll forming machine turns galvanized steel coil into the frame sections of a greenhouse: gutters, glazing bars, crop rails, clip rails and arches. Most lines run 1.2 to 3.0 mm coil at 8 to 20 m\/min, with 12 to 24 forming stations, inline punching and a cut-off that follows the strip.<\/p>\n

Which sections hold a greenhouse together?<\/h2>\n

A greenhouse is not one profile repeated four hundred times. Four to eight sections lock together into a frame that carries glazing, wind, snow and the weight of a crop. Each section has its own coil width, its own steel thickness and its own set of bends, and one greenhouse profile roll forming machine has to cover all of them.<\/p>\n

That is why buyers should read the profile drawing before the machine tonnage. The drawing below is a set we built for a grower: four sections, four coil widths, one line.<\/p>\n

Gutter, hat section, wavy rail and clip rail from one greenhouse project. Coil widths 156, 124, 117 and 62 mm.<\/figcaption><\/figure>\n

Read the coil widths first. The 78 x 40 gutter takes 156 mm strip. The 32 x 25 hat section that clips into the gutter mouth takes 124 mm. The wavy rail takes 117 mm, and the small clip rail only 62 mm. One decoiler has to cover 62 to 156 mm without a rebuild.<\/p>\n\n\n\n\n\n\n\n\n\n

On any greenhouse profile roll forming machine the gutter decides the frame. It carries roof water and truss reaction at the same time, which is why the same drawing usually runs 2.0 to 2.5 mm rather than 1.5 mm. A thin gutter dents at the bracket hole long before the frame itself fails.<\/p>\n

What runs on the line?<\/h2>\n

A greenhouse profile roll forming machine is short compared with a cable tray or racking line. Most installations measure 18 to 25 m from decoiler to run-out table, and they run one shift a day rather than three.<\/p>\n
