C Purlins Introduction

C-shaped steel purlin is automatically processed and formed by a C purlin forming machine. The C purlin roll forming machine can automatically complete the C purlins forming process according to the given C-shaped steel size.

C Purlins Applications

C purlin is widely used in the purlins and wall beams of steel structure buildings, and can also be assembled into light-weight roof trusses, brackets, and other building components. In addition, it can also be used for columns, beams, and arms in light machinery manufacturing.

C Purlin Specification

C-shaped steel purlins are divided into five specifications of 80, 100, 120, 140, 160 according to different heights. The length can be determined according to the engineering design, but considering the conditions of transportation and installation, the total length generally does not exceed 12 meters.

Z Purlins Introduction

Z purlins manufactured by purlin roll forming machine

Z purlin is a common cold-formed thin-walled steel manufactured by a Z purlin roll forming machine with a thickness between 1.6-3.0mm and a cross-section height between 120-350mm. The processing materials are hot-rolled (painted), galvanized, and the processing standards are implemented in accordance with GB50018-2002. Z-shaped purlin is usually used in large steel structure workshops. The processing length and hole are produced according to processing requirements.

Z Purlin Applications

Cold-formed Z-shaped steel has the advantages of adjustable size and high compressive strength. Z purlin is widely used in automobiles, railway vehicles, building doors and windows, transportation, shelves, electrical cabinets, highway guardrails, building steel structures, containers, steel formwork and scaffolding, solar support shipbuilding, bridges, power transmission towers, steel sheet piles, cable trays, Agricultural machinery, furniture, storage, guide rails, keel steel, vegetable greenhouses, pipe supports, municipal construction, and other fields.
