What You Need to Know Before Buying a Roofing Sheet Machine from China

Are you in the market for a roofing sheet machine? If so, there are several things you should consider before making a purchase. With so many options available, it can be overwhelming to choose the right machine for your needs. In this ultimate guide, we’ll cover everything you need to know to make an informed decision when buying a roofing sheet machine from China.

 

1.Types of Roofing Sheet Machines

 

The first thing to consider is the type of roofing sheet machine you need. There are several types available, including corrugated roofing sheet machines, glazed tile roofing sheet machines, standing seam roofing sheet machines, and more. You should determine which type of machine will meet your production needs.

 

2.Production Capacity

 

Next, you need to know the maximum output of the machine to ensure that it can meet your production requirements. Make sure you choose a machine that can produce enough roofing sheets to meet your demand. Normally machine working speed is 0-15mpm. And if you need high speed machine, like 20mpm, 30mpm, it can be customized too, but the faster, the more expensive the machine will be.

 

3.Materials Compatibility

 

You should also consider the materials the roofing sheet machine can work with. Make sure the machine is compatible with the materials you plan to use for your roofing sheets, such as metal, aluminum, or steel. Most commonly used material is GI and PPGI , with thickness of 0.3-0.8mm. The smaller the thickness range, the better roll forming effect.

 

4.Power Consumption

 

It’s essential to understand the power requirements of the machine to ensure that it can be operated efficiently and cost-effectively. Make sure you choose a machine with a power consumption that fits your facility’s capabilities.

 

5.Dimensions and Weight

 

Knowing the size and weight of the machine is also important. Make sure the machine can be transported and installed in your production facility.

 

6.Lead Time

 

Make sure you have a clear understanding of the production and delivery timeline to plan for the installation and operation of the machine.

 

 

7.Quality

 

When it comes to buying a roofing sheet machine from China, quality should be a top priority. Look for manufacturers with a good reputation and a history of producing high-quality machines. Reading reviews from previous customers can also give you an idea of the quality of the machines they produce. Investing in a high-quality machine may cost more upfront, but it can save you money in the long run by reducing maintenance and repair costs.

 

8.Price

 

Price is an important factor to consider when buying a roofing sheet machine from China. However, it’s essential to balance price with quality. Comparing prices from different manufacturers can help you get the best deal, but don’t sacrifice quality for a lower price. Keep in mind that the cheapest option may not always be the best quality.

 

9.Shipping

 

Shipping is another important consideration when buying a roofing sheet machine from China. Make sure you have a clear understanding of the shipping options available to you, including the associated costs and delivery times. For the machines, it is usually shipped by sea, and with full containers. One set of normal speed trapezoidal tile machine or a corrugated tile roofing sheet machine can be put in one 20GP container, one double layer roofing sheet machine or two single layers roofing sheet machines can be put in one 40GP containers. 40GP and 40HQ container’s fee are usually same, but 40HQ container has bigger space, so 40HQ container is more used than 40GP containers when they are needed.

 

10.Payment

 

there are several payment terms available in international trade. Here are some common ones:

Advance Payment: This is when the buyer pays the full amount upfront before the goods are shipped.

Letter of Credit (L/C): This is a document issued by the buyer’s bank that guarantees payment to the seller once the goods are delivered.

Documentary Collection: This is when the buyer’s bank acts as an intermediary to facilitate payment. The seller ships the goods and sends the shipping documents to the buyer’s bank, which then forwards them to the buyer in exchange for payment.

Open Account: This is when the seller ships the goods and extends credit to the buyer. Payment is due at a later date, usually 30, 60, or 90 days after shipment.

Cash on Delivery (COD): This is when payment is made at the time of delivery.

And now 2 most commonly used in roofing sheet machines are TT advance payment and balance before shipment. Or Letter of Credit.

 

11.Support

 

Technical support and training are crucial when it comes to operating a roofing sheet machine effectively. Look for a manufacturer that offers adequate customer support, including technical assistance and training. This can help you avoid downtime and reduce the risk of machine failure.

 

12.Warranty

 

Understanding the warranty terms provided by the manufacturer is also essential. Make sure you know what is covered under the warranty and for how long. This will help you protect your investment in case of any defects or issues with the roofing sheet machine. Some manufacturers may offer extended warranties for an additional fee, so consider this option if it makes sense for your production needs.

 

In conclusion, buying a roofing sheet machine from China can be a significant investment. By considering these factors, you can make an informed decision that meets your production needs and protects your investment.

steel frame CZ purlin automatic changing size forming machine

C / Z purlin is widely used in modern steel structure buildings. As the purlin of the house, Z purlin has better bearing capacity

The internal supporting part of steel structure, high-strength galvanized steel plate, is precision processed and cold rolled into C and Z purlin.

Purlin can be divided into main purlin and secondary purlin.

The main purlin is connected and installed on the roof and exterior wall structural column beam, and the secondary purlin is used to connect the roof panel and exterior wall panel to the foundation structure. The primary and secondary purlin are the main structural components commonly used in modern steel structure architectural design.

C purlin automatically processed and formed by C purlin forming machine. C purlin forming machine can automatically complete the forming process of C purlin according to the given size of C purlin.

C purlin is processed by cold bending of hot coil plate, with thin wall, light weight, excellent section performance and high strength. Compared with traditional channel steel, the same strength can save 30% of materials.

For this machine, because of the normal thickness of the material, the C purlin machine can not run very fast, normally it can produce 4 or 6 meters C purlin within one minute.

But with the improvement of technology, now we can make high-speed steel frame purlin machine. The speed can reach 20 meters per minute.( without punching hole process )

We can also make this machine can automatic adjust the C purlin product sizes by adjust parameters on the PLC computer, which is very easy to operate.
