Forming Angle & Profile Mold Design Guidance
This Multibeam Purlin Roll Forming Machine adopts professional multi-stage gradual bending and precise angle compensation technology specially designed for multi-rib reinforced purlin profiles. Different from ordinary single-section purlin forming, this equipment divides the complex multi-angle bending process into multiple progressive rolling passes, which effectively disperses forming pressure and avoids material cracking, edge distortion or coating peeling.
Each group of forming rollers adopts independent angle calibration and symmetrical trajectory design. It precisely controls the vertical angle of the main beam, the bending angle of reinforcing ribs and the flatness of the flange surface. The machine supports fine adjustment of rolling angle and gap according to different steel thickness and tensile strength, realizing accurate springback compensation.
This scientific mold angle design ensures consistent geometric symmetry, uniform stress distribution and high straightness of finished multibeam purlins, providing stable structural load-bearing performance for large-span and heavy-duty steel construction projects.
Application Scope
Multibeam purlins manufactured by this roll forming machine feature high rigidity and excellent anti-bending performance, tailored for heavy-load and large-span structural projects that demand superior wind and snow resistance.
They are widely adopted as primary load-bearing beams and secondary supporting frames for large-span steel workshops, logistics warehouses, distribution centers and cold storage buildings. In the new energy sector, these reinforced purlins serve as main structural components for large solar carports, photovoltaic canopies and ground-mounted PV power stations, especially for projects with wide span requirements.
Besides, the profiles apply to agricultural PV complementary greenhouses, heavy mechanical equipment mounting supports, municipal large-span steel structure frameworks and stadium roof steel systems. They are also a preferred structural solution for industrial mezzanine floors and other engineering scenarios requiring outstanding long-term structural stability under harsh outdoor conditions.
FAQ
What is the difference between multibeam purlin and ordinary C/Z purlin?
Multibeam purlin has several reinforced ribs on the profile. It has higher stiffness and better anti-bending performance, suitable for large-span and heavy-load projects, while standard C/Z purlins are used for lighter load conditions.
What sizes of multibeam purlins can this machine produce?
The adjustable web height ranges from 100mm to 350mm, with applicable material thickness from 1.8mm to 3.5mm. Custom profiles can be developed according to your technical drawings.
Can the machine punch holes during forming?
Yes. It is equipped with inline hydraulic punching station. Servo feeding controls punching position within ±0.5mm. Custom hole spacing and hole types are supported.
Can it process galvanized steel coils for outdoor projects?
Yes. Polished chrome rollers protect the galvanized anti-corrosion coating. Finished multibeam purlins keep stable performance under outdoor harsh weather.
What warranty and after-sales services do you provide?
We provide 12-month whole machine warranty and lifelong online technical support. Non-human damaged spare parts are free within warranty. Overseas on-site installation, commissioning and operator training are available with 24-hour online support.
