ALEKVS purlin roll forming machine for sale

A purlin forming machine is a kind of cold bending forming equipment that is mainly used for the purlins required for steel structure buildings, factory buildings, storage shelves, and agricultural greenhouses.

Its working principle is to press the steel coil in the middle through the pressure and friction between the steel rollers to achieve the effect of leveling.

  • Steel structure industry: mainly used for the production of C-shaped and Z-shaped steel.
  • Construction industry: used for the production of purlins, car body panels, color steel pressed tiles, keels, and other building materials.
  • Photovoltaic bracket: used for the production of photovoltaic brackets and other equipment.

Purlin Roll Forming Machine

Equipment that continuously processes metal sheets (such as steel, aluminum, stainless steel, and aluminum alloy) into purlins of specific shapes through cold bending technology.

ALEKVS  Purlin Roll Forming Machine Factory

ALEKVS’s purlin equipment can produce various purlins, such as C-type, Z-type, U-type, etc., to meet different structural needs.

ALEKVS’s CZ switching purlin roll forming machine achieves automated production, allowing for mass production and reducing manual operation.

1.0 What Materials Can the Purlin Roll Forming Machine Process?

Steel is one of the most common materials produced by purlin roll-forming machines. C-type and Z-type steel purlins are especially lightweight, thin-walled, and have high strength.

Aluminum: Aluminum purlins are lightweight, corrosion-resistant, and suitable for construction projects that have weight requirements.

Stainless Steel: Stainless steel C and Z purlins not only have the strength and load-bearing capacity of steel purlins but also excellent corrosion resistance and long service life.

Aluminum Alloy Purlins: Ideal for industries that require aesthetics and lightweight properties.

2.0 Working Principle of the Purlin Roll Forming Machine

Working Principle of the Purlin Roll Forming Machine

Raw Material: The raw materials are typically in the form of coils or bars (such as steel, aluminum, stainless steel, or aluminum alloy) and need to be pre-cut or adjusted to the length and width suitable for machine processing.

Decoiler Feeding: The decoiler feeding device usually includes rollers, conveyor belts, or robotic arms. It feeds the raw materials into the processing area of the purlin roll-forming machine at a preset speed and position, controlled by the decompiler’s PLC system.

Cold Roll Forming Process: As the raw material passes through high-strength custom molds, the molds apply pressure and deformation forces, gradually forming the desired purlin shape.

Roll Forming: The purlin roll forming machine can also adopt roll forming methods. Sequentially arranged mold rollers continuously roll the raw material, gradually shaping it into the desired purlin form.

Correction and Adjustment: After roll forming, the purlin passes through a straightening device, ensuring the straightness and shape of the purlin.

Punching (Optional): A punching device creates holes in the purlin, facilitating subsequent installation and fixation.

Cutting: When the purlin reaches the preset length by the PLC, it is precisely cut by the cutting device.

3.0 Applications of Purlin Roll Forming Machines in the Construction Industry

Purlins are primarily used to support roofing sheets, enhancing the overall stability and safety of the building.

The framework formed by purlins, beams, and columns enhances the building’s seismic and wind resistance.

Using lightweight, high-strength purlins reduces the building’s weight while ensuring structural strength.

Prefabricated purlins can be directly installed on-site, improving construction efficiency and reducing construction time.

Purlin materials have strong corrosion resistance and durability, extending the building’s lifespan.

4.0 Difference Between C-Type Purlin Roll Forming Machine and CZ Interchangeable Purlin Roll Forming Machine

C-Type Purlin Roll Forming Machine: Specially designed for producing C-type purlins, with the purlin cross-section shaped like a “C.” It is suitable for projects with a limited budget that only require C-type purlins.

CZ Interchangeable Purlin Roll Forming Machine: By adjusting or replacing molds, it can switch between producing C-type and Z-type purlins to meet different needs. It is ideal for companies that require multiple product specifications, offering high cost-effectiveness.

CZ Interchangeable Purlin Roll Forming Machine: ALEKVS’s CZ interchangeable models are mostly equipped with a quick-switch feature to minimize downtime.
