Coil is decoiled, leveled and fed through a punch press, then through 14 to 24 roll stations, and cut to length at the end. The section becomes the roof and wall framing of a steel building.<\/p><\/details>\n        <details><summary>What is the difference between a C purlin and a Z purlin?<\/summary><p>A C purlin has a flat web with two square flanges and is used where a simple span is enough. A Z purlin has flanges bent in opposite directions, so two sections nest and overlap over a rafter. The overlap makes the run continuous and carries more load on the same steel weight.<\/p><\/details>\n        <details><summary>What thickness can a purlin line form?<\/summary><p>Standard purlin machines run 1.5 to 5.0 mm galvanized coil. A reinforced version forms up to 5.5 mm for infrastructure and heavy roof work. Below 1.5 mm the section tends to twist during forming, so light gauges are usually run on a separate light gauge mill.<\/p><\/details>\n        <details><summary>How fast does a purlin roll forming machine run?<\/summary><p>10 to 15 m\/min is normal when a hydraulic punch and shear are inline. With a servo punch and a flying saw the line runs 20 to 30 m\/min. Real output depends on hole density, because the press, not the mill, sets the cycle on a heavily punched purlin.<\/p><\/details>\n        <details><summary>Can one machine produce both C and Z purlins?<\/summary><p>Yes. A switchable C and Z mill changes section type without re-tooling every stand, and motorized web and flange adjustment sets the size from the HMI. Changeover is minutes on a cassette design and several hours on a fixed mill with manual spacers.<\/p><\/details>\n        <details><summary>How much does a purlin roll forming machine cost?<\/summary><p>A dedicated C line with manual adjustment starts near USD 55,000. A switchable C and Z line with servo punching and a flying saw runs USD 110,000 to 180,000. Multibeam machines sit above that. On any purlin roll forming machine, section range, thickness, changeover system and the number of hole patterns move the price most.<\/p><\/details>\n        <details><summary>What is the lead time for a purlin line?<\/summary><p>Build time is 45 to 90 days after the drawing and deposit are confirmed. Sea freight adds 20 to 45 days depending on the destination port. Die sets for a second hole pattern are usually built in parallel and ship with the machine.<\/p><\/details>\n      <\/div>\n    <\/div>\n  <\/section>\n\n  <section class=\"related\">\n    <div class=\"wrap\">\n      <div class=\"head\">\n        <div>\n          <span class=\"kicker\">Related reading<\/span>\n          <h2>Guides that help you specify the line<\/h2>\n        <\/div>\n        <p>Background on the purlin roll forming machine, the steel and the cutoff, written for buyers rather than engineers.<\/p>\n      <\/div>\n      <div class=\"rel-grid\">\n        <a class=\"rel\" href=\"https:\/\/believeindustry.company\/roll-forming-machine-line\/\">\n          <span class=\"lbl\">Line basics<\/span>\n          <h3>Roll Forming Machine Line: Stations, Speed and Cutoff<\/h3>\n          <p>How station count and cutoff type set the speed and the price of any line.<\/p>\n          <em>Read the guide &rarr;<\/em>\n        <\/a>\n        <a class=\"rel\" href=\"https:\/\/believeindustry.company\/how-to-select-steel-coil-roll-forming\/\">\n          <span class=\"lbl\">Material<\/span>\n          <h3>How to Select Steel Coil for Roll Forming<\/h3>\n          <p>Grade, coating and thickness tolerance, and what each one does to the finished purlin.<\/p>\n          <em>Read the guide &rarr;<\/em>\n        <\/a>\n        <a class=\"rel\" href=\"https:\/\/believeindustry.company\/what-is-flying-shear-roll-forming\/\">\n          <span class=\"lbl\">Cutoff<\/span>\n          <h3>What Is a Flying Shear in Roll Forming<\/h3>\n          <p>When a flying cut beats a stop to cut, and how it changes line output.<\/p>\n          <em>Read the guide &rarr;<\/em>\n        <\/a>\n        <a class=\"rel\" href=\"https:\/\/believeindustry.company\/roll-forming-machine-punching-die-installation\/\">\n          <span class=\"lbl\">Tooling<\/span>\n          <h3>Punching Die Installation and Alignment<\/h3>\n          <p>Clearance, alignment and the checks that keep holes in tolerance.<\/p>\n          <em>Read the guide &rarr;<\/em>\n        <\/a>\n      <\/div>\n      <p style=\"margin-top:26px;color:#5e6b72;font-size:14px\">Purlins are one family in the wider <a href=\"https:\/\/believeindustry.company\/roll-forming-machine\/\" style=\"color:#bd4e1e;text-decoration:underline\">roll forming machine<\/a> range.

The overlap makes the run continuous and carries more load on the same steel weight.\"}},{\"@type\":\"Question\",\"name\":\"What thickness can a purlin line form?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Standard purlin machines run 1.5 to 5.0 mm galvanized coil. A reinforced version forms up to 5.5 mm for infrastructure and heavy roof work. Below 1.5 mm the section tends to twist during forming, so light gauges are usually run on a separate light gauge mill.\"}},{\"@type\":\"Question\",\"name\":\"How fast does a purlin roll forming machine run?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"10 to 15 m\/min is normal when a hydraulic punch and shear are inline. With a servo punch and a flying saw the line runs 20 to 30 m\/min. Real output depends on hole density, because the press, not the mill, sets the cycle on a heavily punched purlin.\"}},{\"@type\":\"Question\",\"name\":\"Can one machine produce both C and Z purlins?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes. A switchable C and Z mill changes section type without re-tooling every stand, and motorized web and flange adjustment sets the size from the HMI. Changeover is minutes on a cassette design and several hours on a fixed mill with manual spacers.\"}},{\"@type\":\"Question\",\"name\":\"How much does a purlin roll forming machine cost?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"A dedicated C line with manual adjustment starts near USD 55,000. A switchable C and Z line with servo punching and a flying saw runs USD 110,000 to 180,000. Multibeam machines sit above that. Section range, thickness, changeover system and the number of hole patterns move the price most.\"}},{\"@type\":\"Question\",\"name\":\"What is the lead time for a purlin line?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Build time is 45 to 90 days after the drawing and deposit are confirmed. Sea freight adds 20 to 45 days depending on the destination port. Die sets for a second hole pattern are usually built in parallel and ship with the machine.\"}}]}<\/script>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Purlin roll forming machine series Purlin Roll Forming Machine for C, Z, U and Sigma Sections A purlin roll forming machine turns galvanized coil into the secondary framing of a steel building.
