As a professional foreign trade manufacturer specializing in cold roll forming equipment, we supply high-performance automatic C purlin forming machines tailored for global steel structure factories, construction material manufacturers, and engineering contractors. This C section steel forming equipment can automatically complete continuous feeding, leveling, multi-pass rolling forming, hydraulic punching, online stamping, and fixed-length flying cutting in one fully automated process. Designed for producing high-strength C-shaped steel purlins widely used in factory warehouses, large workshops, logistics parks, agricultural greenhouses, and commercial building roofing & wall supporting systems, our C purlin machine is the most cost-effective core equipment for medium and large steel structure production lines worldwide.

Many overseas buyers face common production pain points: traditional C purlin machines have low forming precision, easy deformation, slow production speed, unstable hole position accuracy, and frequent downtime. Poor equipment quality leads to unqualified purlin products, delayed project delivery, and increased after-sales maintenance costs. Our upgraded heavy-duty C purlin forming machine adopts integral thickened frame, high-precision alloy rollers, and intelligent PLC synchronous control system. It runs stably 24/7 with low noise, high yield, and ultra-low failure rate, helping customers produce standard C purlins that fully meet international steel structure engineering acceptance standards.

Main Application & Production Range

Our automatic C purlin forming machine can produce various standard and non-standard C-shaped steel profiles with smooth surface, accurate size, and excellent mechanical strength:

Standard C purlin: 80mm–300mm web height, fully adjustable width and thickness without roller replacement

Thickened load-bearing C steel: for high-rise steel structure main force-bearing support beams

Perforated C purlin: automatic online punching for installation holes, connecting holes, and process holes

Custom special C profile: non-standard size, special hole spacing, reinforced rib customized according to drawings

Raw material compatibility: galvanized steel coil, hot-rolled carbon steel, cold-rolled steel strip, aluzinc steel strip

Core Strengths Why Global Steel Structure Buyers Choose Our C Purlin Forming Machine

Heavy-Duty Integral Welded Frame, No Deformation for Decades

The whole machine base adopts large thick H-beam and solid steel plate full integral welding. After high-temperature stress relief annealing treatment, the frame has no welding internal stress. During long-term high-speed and heavy-load continuous operation, the machine body will not shake, tilt or deform. Compared with ordinary light-duty machines on the market, our industrial-grade frame has stronger rigidity, better stability, and longer service life, perfectly adapting to harsh factory environments such as high temperature, heavy dust, and high humidity in overseas regions.

High-Precision Alloy Forming Rollers, Wear-Resistant & Long Lifespan

All forming rollers are made of high-quality high-hardness alloy steel, processed by vacuum quenching and precision mirror grinding. The hardness reaches HRC 58–62 degrees. The rollers are anti-wear, anti-pressure, and anti-corrosion. No scratches, no burrs on the surface of finished C purlins. The dimensional consistency of each batch of profiles is extremely high. The roller service life is more than 3 times that of ordinary cast iron rollers, greatly reducing later replacement costs and production downtime losses for customers.

Intelligent PLC Automatic Size Adjustment, Save Labor & Time

Equipped with Siemens or Delta brand industrial PLC control system and multi-language touch screen panel, supporting English, Spanish, Arabic, Russian, French and other languages. Workers only need to input target C purlin height, width, thickness, and length on the screen. The machine automatically adjusts parameters and switches specifications without manual roller disassembly and alignment. One-key switching of hundreds of stored production formulas, simple operation, low dependence on skilled workers, effectively saving labor costs.

High-Speed Flying Cutting System, Burr-Free & High Precision

Adopt hydraulic follow-up non-stop flying saw cutting technology. No need to stop the machine during cutting, realizing continuous high-speed production. The cutting section is flat, no burr, no deformation. The fixed-length tolerance is controlled within ±0.2mm. The produced C purlin has good straightness, uniform radian, stable assembly, fully meeting the strict requirements of large steel structure engineering bidding and on-site construction.

Low Energy Consumption & Low Failure Rate, Reduce Operating Costs

Equipped with energy-saving frequency conversion driving system, effectively reducing power consumption by 15%–20%. All electrical components are original international brand parts, with stable performance, waterproof and dustproof design. The whole machine adopts fully sealed transmission structure, not easy to be damaged in harsh environments. Standardized wearing parts are easy to purchase locally overseas, greatly reducing daily maintenance difficulty and after-sales cost.

Full Process Quality Inspection, Strict Factory Testing

Every C purlin forming machine undergoes strict multi-process inspection before delivery, including frame structural test, roller precision detection, electrical aging test, 24-hour full-load continuous running test, and real material trial production test. Only fully qualified equipment can be packaged and shipped, ensuring zero quality problems after arriving at the customer’s factory.
