How to choose a suitable C purlin forming machine for solar structure used?

 

 

1. Daily Output and Line Speed

Normal Forming Speed: 15-20m/min, it is suitable for small and middle scale factory.

High forming speed: 25-35m/min, it is for big scale and quick delivery engineer project, we should consider the synchronicity of high-speed punching and cutting.

Without hole punching, the C purlin forming machine’s daily output will be 5000~15000 meters.

 

2. Line Speed with Punching Actions

Hydraulic stop punch: a short pause during punching holes, so the c purlin forming machine line speed will be slow but higher punching precision. When the hole design is complex and more higher precision, this type of punching is the first choice, but whole line producing speed will be slowly, too.

On Line Flying Punch: Online dynamic punching and cutting, it is the fast speed and high efficient line, the best choice for bigger hole distance and big scale project, the output can improve above 30% of total.

 

3. Semi-auto Type Change or Full auto PLC Type Change

Manual replacement D-spacers and adjust cutting blades, total need several hours for type change, it is suitable for only 2-4 sizes for saving machine cost. This type of C purlin machine is suitable for small processing factory andfactory has skilled opeator run the purlin forming machines.

PLC Auto Type Change Sizes c purlin forming machine is good for processing many sizes solar structure project, well savely size changing time.

 

4. Vertical Angles on C purlins

Verticality error: Generally required to be ≤±1mm, high-end equipment can control it within ±0.5mm.

Influencing factors: Roll precision, frame rigidity, shaft material, straightening device.

Metal purlin’s verticality directly affects solar structure’s installation quality, so it must be strictly controlled. So when buying the c purlin forming machine, should check with suppliers if the machine include on-line correction/straightening device.

 

5. Purlin Forming Machine’sAccuracy and Stability

Forming Stations: Normally 14-22 stations. More stations more stable forming and more complete stress release.

Roll material: Bearing steel (such as GCr15) is superior to ordinary steel. It requires quenching treatment (HRC58-62°), if you need more harder rollers, we can choose Cr12, too.

Shaft material and Diameter: 40Cr or 45# steel with quenching and tempering treatment. Larger diameter results in better rigidity.

Precision is the core value of one purlin roll forming machine and the foundation for ensuring finished product quality.

The suitable material forming rollers and shafts material are important, needs good heat treatment, so ensure well of the purlin forming machine equipment lifespan and final product precision. More forming stations c purlin forming machine, better long term stability of the producing line.

 

6. Process layout and punching method

Punching before forming: Punching holes on a flat surface is simple, but the holes may slightly deform after forming.

Forming before punching: Punching holes on a three-dimensional surface offers high precision, but the equipment is more complex.

Factory requirements: Equipment length is generally 15-25 meters; sufficient space must be reserved for operation and logistics.

Solar structure’s hole are normally on C purlin web or flange, we suggest choose three-axis multi-station punching equipment for whole punching.

 

7. Budget and Cost Control

A comprehensive evaluation is needed, but not just comparing prices:

Higher automation level purlin machine means larger initial investments, but lower labor costs and higher efficiency;

Clearly define your target production capacity and product positioning, and choose the most suitable price range;

Pay attention to the warranty period (usually 12 months), after-sales service network, and spare parts supply.

 

 

What are C purlin roles for different sizes and thickness in solar structure industry?

 

Here are the some items for solar channel processing factory consideration:

Web Size C50-100: Suitable for distributed photovoltaic systems and commercial and industrial rooftops. Used as main purlin to support solar panels, this size range is suitable for small spans and low load photovoltaic systems.

Web Size 120-200: Suitable for ground mounted power stations and agricultural-solar hybrid projects. As main support structural beam or secondary beam, this C purlin can bear larger spans heavier wind and snow loads, so they are the main supporting component of solar support system.

Steel Thickness Range 1.5-2.0mm: This steel thickness range can meet the requirements for conventional wind and snow pressure, it is good for weight reduction and cost reduction,  they are more suitable for light weight roof mounting system.

Hole Sizes and Hole Positions: round hole or slot hole? Hole distance? All the holes are for connecting solar rack’s each parts, they are good for improving onsite engineer time and quick for installation. We should leave several holes on solar structure for standby, too.

 

 

Summary and Action Recommendations

Clarify Your Business Positioning: First, clarify your business model – do you primarily handle large, standardized, high-volume orders, or focus on customized, multi-specification, small-batch production?

 

Balancing Efficiency and Flexibility:

Large Volume, Few Specifications: Prioritize speed; choose high-speed (>20m/min), online punching, and equipment with low changeover requirements.

Multiple Varieties, Multiple Specifications:Focus on rapid response; CZ integrated machines, automatic changeover (1-5 minutes), and high automation are key. Speed can be more flexible.

Maintain Precision: Regardless of the type chosen, corner perpendicularity, length accuracy, and hole position accuracy are crucial for successful product installation. On-site testing is essential when evaluating equipment.

 

Calculate Overall Costs: Consider the equipment price, expected labor savings, capacity increases, and maintenance costs when calculating the return on investment, rather than simply comparing the initial purchase price.
