CZ Purlin Forming Machines
Jan 31, 2024
CZ purlin forming machines are roll forming equipment used to produce C and Z shaped purlins from metal coils. Purlins are structural beams widely used in metal buildings and structures.
What Is A CZ Purlin?
A CZ Purlin is a type of structural component used in construction and building applications, particularly in the framing of roofs and walls. Purlins are horizontal beams or members that provide support to the roof covering or wall cladding and help distribute the load of the building’s roof or walls to the main structural frame, such as columns or rafters. They are commonly used in metal building construction.
The term “CZ Purlin” typically refers to two different shapes of purlins:
- C Purlin: A C-shaped purlin is formed like the letter “C” in cross-section, with two horizontal flanges and a vertical web connecting them. C purlins are commonly used for roof framing and wall girts.
- Z Purlin: A Z-shaped purlin is formed like the letter “Z” in cross-section, with a pair of vertical flanges connected by a horizontal web. Z purlins are typically used as roof purlins, and their shape provides added strength and stability compared to C purlins.
CZ Purlins are made from various materials, including steel and aluminum, and they come in different sizes and thicknesses to suit the specific load-bearing requirements of a building’s design. They are essential components in the construction of steel-framed and metal-clad buildings, providing structural support for the roof and walls while also helping to maintain the overall stability and integrity of the structure.

Working Process Of CZ Purlin Forming
The working process involves uncoiling the metal coil, feeding it through progressive forming stations to shape the C or Z profile, and cutting the beams to length:
- •The uncoiling unit feeds the metal strip into the machine through guiding rolls
- •Accumulator controls loop of material for stable feeding
- •The metal strip passes through forming stations with upper and lower forming rollers
- •Forming rollers have customized blades to bend the strip into C or Z shape through stages
- •Hydraulic system adjusts the space between rollers
- •The profiled purlin beam passes through the cutting station
- •Cutting blades slice the beam at preset length into individual purlins
- •Formed purlins are stacked on the output table
