Forming Angle & Profile Mold Design Guidance
This C Purlin Cold Roll Forming Machine uses multi-stage gradual angle bending technology to produce precise C-shaped profiles. Instead of one-time sharp bending, the total bending angle is split into several rolling passes to prevent steel cracking, arc distortion and coating damage.
Each roller set is precisely calibrated. The flange bending angle and web vertical angle are strictly controlled, keeping the right-angle tolerance within ±0.3°. Operators can fine-tune rolling angles and feeding pressure for different steel thickness and hardness, fixing common defects like twisting, flaring and uneven bending.
All mold angles follow international steel structure standards. Smooth arc transition preserves the galvanized coating and ensures consistent geometry in mass production. Accurate forming angles guarantee easy assembly and reliable load performance for steel buildings and PV support frames.
C purlins produced by this cold roll forming machine are essential secondary load-bearing components widely used across construction and renewable energy sectors. They serve as roof and wall purlin systems for steel structure workshops, warehouses, cold storage facilities and large-span industrial buildings. In the new energy industry, these C purlins form critical parts of ground-mounted photovoltaic stations, rooftop solar mounting brackets and solar carport support frames. They are also widely applied in agricultural PV greenhouses, logistics warehouse mezzanine floors, municipal steel structure projects and industrial equipment fixing frames. With strong bending resistance and good weather resistance, the purlins can withstand wind and snow loads, making them suitable for both indoor steel buildings and long-term outdoor photovoltaic installations.
FAQ
What is the difference between cold roll forming and hot forming for purlins?
Cold roll forming processes steel coil at ambient temperature. It keeps the original strength of steel, saves heating cost and provides smoother surface. Hot forming requires high temperature heating and is rarely used for standard C purlin production.
What size of C purlins can this cold roll forming machine produce?
It can produce C purlins with web height ranging from 80mm to 300mm, material thickness from 1.2mm to 3.0mm. Customized sizes are available upon your engineering drawings.
Can this machine punch holes on C purlins during cold forming?
Yes. It is equipped with inline hydraulic punching station. The servo feeding system guarantees punching tolerance within ±0.5mm. Custom hole patterns and spacing are supported for bolt connection.
Can the machine form galvanized steel coils?
Yes. The chrome-plated rollers protect the galvanized coating from scratching during cold bending. Finished C purlins retain anti-corrosion performance and fit long-term outdoor applications.
What warranty and after-sales services do you offer?
We provide a 12-month warranty for the whole machine 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 technical support.
