Profile steel is a perfect steel material

Profile steel is a perfect steel material that can be utilized to make numerous items, including welded balls. At that point everybody realizes how to utilize C-profile steel to make welded balls?c profile steel suppliers It appears that it is as yet important for specialists to present us. There are two regularly utilized techniques for making patch balls, one is hot rolling and the other is cold rolling. The welding balls showing up available are fundamentally hot rolled. To begin with, the steel plate clear is hot folded into a half of the globe, and afterward a circle is shaped by methods for stacking and emptying preparing and get together welding.

Profile steel is a perfect steel material

The welded ball delivered along these lines has a lethal shortcoming, which is anything but difficult to create uneven divider thickness. With respect to the roundness of the C-formed steel ball, it must be controlled in the state to keep away from huge blunders. Else, it won’t just influence the get together size of the ball, yet in addition aim the hub to be unpredictable, making the completed ball width littler.

On the off chance that the steel is contrasted and the steel of a similar quality, it can spare 30% of the material, and the Z-formed steel shouldn’t be handled during the trim procedure, and there is no carbon and hurtful gases. There is no contamination to our condition. The elements of the steel structure stockroom area are high accuracy, and the length of the steel structure can be planned and slice as indicated by explicit needs.

The conveyance time of Z-profile steel is exceptionally short, and it is extremely advantageous when it is utilized for development and establishment, which can adequately abbreviate our development period. Additionally, our Z-molded steel can likewise be planned by the particular generation needs of clients. In a specific range, it tends to be joined and delivered voluntarily. So now we will locate that numerous individuals will pick Z-molded steel, and Z-formed steel is gradually developing.z profile steel producer

The working guideline of the steel is for the most part to put the steel on the virus twisting machine, and in the wake of reaching the roller driven by the reducer, the squeezing handle is nourished firmly to turn over the engine oil siphon set, and the high weight oil yield by the electric oil siphon goes through the flood valve. In this procedure, the required weight can be acclimated to enter the square into the electro-water driven valve. The electro-water powered valve and the run switch control the chamber to work, the working chamber progresses, and the squeezing of the I-shaft and the three supporting rollers does not happen. At the point when the bowing distortion begins, the length of the chamber re-drive is 10mm-15mm each time. The primary engine is turned forward or switched. The primary engine drives the I-pillar to work over and again.

Like other cold-framed steels, the issue looked in the generation of steel profiles is the issue of inner pressure. Because of the enormous interior worry of the material, when it is put into utilization, it might be twisted, which may influence its utilization. Where do these burdens originate from? The worry of cold-shaped C profile steel can’t be maintained a strategic distance from. During the time spent loosening up, moving shearing, and shutting of cold-framed C-profile steel, certain interior anxieties are included, for the most part because of mechanical driving distortion.

Cold-shaped steel C profile has a specific pressure. Furthermore, if the steel structure distribution center isn’t showered with a groundwork, the rust and passivation procedure will likewise discharge its inside pressure, causing bowing and contorting. Without any approach to keep away from, the pressure must be diminished by sensible task. As producers and clients, it is additionally important to concentrate on this issue to guarantee that cool framed C-segment steel can be generally utilized.

Photovoltaic support design planning steps

Photovoltaic support design planning steps

1, Geographical location

Determine the geographical location of the mounting bracket, located in the north latitude, east longitude, etc. in order to choose the best angle.

2, climatic conditions

Understand the basic conditions of the local spring, summer, autumn and winter seasons, temperature, rainfall, wind, etc., to ensure that the design is realistic.

3, photovoltaic bracket square array design

The placement and placement angle of the PV module square matrix, azimuth and inclination angle calculation should be considered in combination with the following requirements: continuity uniformity and maximumity. The inclination and azimuth need to be consistent.

4, the calculation of stent strength

The design of the photovoltaic support requires that the support can bear various loads, and the material selection and quantity of the support should be considered, and the strength should be determined.

5, grounding lightning protection

Preventing lightning strikes and system leakage causes various safety accidents. Therefore, it is necessary to embed the grounding body in the foundation construction. In addition, lightning rods are also necessary.

Profile steel is an ideal steel material

Profile steel is an ideal steel material that can be used to make many products, including welded balls. Then everyone knows how to use C-profile steel to make welded balls? It seems that it is still necessary for experts to introduce us. There are two commonly used methods for making solder balls, one is hot rolling and the other is cold rolling. The welding balls appearing on the market are basically hot rolled. First, the steel plate blank is hot rolled into a hemisphere, and then a sphere is formed by means of loading and unloading processing and assembly welding. steel c profile manufacturer

Profile steel is an ideal steel material

The welded ball produced in this way has a fatal weakness, which is easy to produce uneven wall thickness. As for the roundness of the C-shaped steel ball, it must be controlled in the state to avoid large errors. Otherwise, it will not only affect the assembly size of the ball, but also cause the node to be eccentric, making the finished ball diameter smaller.

If the steel is compared with the steel of the same strength, it can save 30% of the material, and the Z-shaped steel does not need to be processed during the molding process, and there is no carbon and harmful gases. There is no pollution to our environment. The dimensions of the steel structure warehouse section are very high precision, and the length of the steel structure can be designed and cut according to specific needs.

The delivery time of Z-profile steel is very short, and it is very convenient when it is used for construction and installation, which can effectively shorten our construction period. Moreover, our Z-shaped steel can also be designed according to the specific production needs of customers. In a certain range, it can be combined and produced at will. So now we will find that many people will choose Z-shaped steel, and Z-shaped steel is slowly developing.z profile steel manufacturer

The working principle of the steel is mainly to place the steel on the cold bending machine, and after contacting the roller driven by the reducer, the pressing handle is fed tightly to start the motor oil pump set, and the high pressure oil output by the electric oil pump passes through the overflow valve. In this process, the required pressure can be adjusted to enter the block into the electro-hydraulic valve. The electro-hydraulic valve and the jog switch control the cylinder to work, the working cylinder advances, and the pressing of the I-beam and the three supporting rollers does not occur. When the bending deformation starts, the length of the cylinder re-propulsion is 10mm-15mm each time. The main motor is turned forward or reversed. The main motor drives the I-beam to work repeatedly.

Like other cold-formed steels, the problem faced in the production of steel profiles is the problem of internal stress. Due to the large internal stress of the material, once it is put into use, it may be deformed, which may affect its use. Where do these stresses come from? The stress of cold-formed C profile steel cannot be avoided. In the process of unwinding, rolling shearing, and closing of cold-formed C-profile steel, certain internal stresses are added, mainly due to mechanical forcing deformation.

Cold-formed steel C profile has a certain stress. In addition, if the steel structure warehouse is not sprayed with a primer, the rust and passivation process will also release its internal stress, causing bending and twisting. In the absence of any way to avoid, the stress can only be reduced by reasonable operation. As manufacturers and users, it is also necessary to focus on this issue to ensure that cold-formed C-section steel can be widely used.

Inspection and maintenance method of photovoltaic modules

Photovoltaic modules are the core components of photovoltaic power generation. In order to operate normally in photovoltaic power plants, it is necessary to inspect and maintain the components of photovoltaic power plants. Solar modules: also called solar panels, usually by solar cells, according to a certain power. z profile steel supplier,And size requirements, a set of power generation units consisting of circuit connections and packaged together by a frame. The components are the basic building blocks of a photovoltaic power generation system.

1.Actively check the ash and dirt of the components. If the ash and dirt are serious, it is necessary to arrange cleaning.

Inspection and maintenance method of photovoltaic modules

2.Fully understand the parameters of PV modules, make detailed operation and maintenance plans for targeted operation and maintenance of PV modules, and make plans according to requirements.

3.The choice of cleaning time

The cleaning of photovoltaic modules of photovoltaic power plants should be carried out in the morning, evening, night or rainy days. It is strictly forbidden to choose cleaning before or after noon or during periods of strong sunlight. Mainly consider the following two reasons: to prevent the loss of photovoltaic array power generation caused by artificial shadows, and even the hot spot effect; the surface temperature of the components is quite high at noon or when the light is good, preventing cold water from causing glass or glass surface Component damage.

At the same time, in the morning and evening cleaning, it is also necessary to select the time period when the sunlight is weak. It is also conceivable to carry out cleaning work in sometimes rainy weather. At this time, the cleaning process is relatively efficient and thorough because of the help of precipitation. The cleaning process should pay attention to personnel safety and wear safety equipment to prevent leakage and bumps. It is strictly forbidden to step on or otherwise borrow the component board and bracket during the cleaning process.

Cleaning cycle and area planning. Since large-scale photovoltaic power plants occupy a large area, the number of components is large, and the time required for cleaning operations is short every day, the cleaning of photovoltaic power plants needs to be planned according to the electrical structure of the power station to reduce the loss of power generation.

4.cleaning steps.

Conventional cleaning can be divided into general cleaning and rinsing cleaning.

One.Ordinary cleaning, use a dry small broom or rag to sweep off the surface of the PV module such as dry floating ash, leaves, etc. For hard foreign objects such as dirt, bird droppings, and viscous objects attached to the glass, scraping may be performed with a slightly hard blade or gauze, but care must be taken not to use a hard material to scratch and prevent damage to the glass surface. Whether it is necessary to perform cleaning and cleaning in terms of cleaning effect. omega profile manufacturer

Two.Rinse and clean. For objects that are close to the glass and have stains such as bird droppings, plant juice, or wet soil, which cannot be cleaned, they need to be cleaned. The cleaning process is generally carried out with clean water and with a flexible brush. If oily dirt or the like is encountered, the contaminated area may be separately cleaned with detergent or soapy water.

Note: Wipe the PV module with a dry or damp soft and clean cloth. Do not use corrosive solvents or wipe the PV module with a hard object. The PV module should be cleaned at an irradiance of less than 200W/m2. Liquid cleaning components with large temperature difference of components; it is strictly forbidden to clean PV modules under meteorological conditions with wind force greater than 4, heavy rain or heavy snow; the warning signs on the PV modules must not be lost; check the connection of the junction boxes of the components, whether there is looseness or heat , discoloration phenomenon, and timely processing.

The US solar industry is highly competitive

Today, the US solar industry is highly competitive. Wood Mackenzie Power&Renewables pointed out that “fierce competition” is one reason for the increase in customer acquisition costs, as installers “spend more money to win the bid.” Resolving competition is an essential part of most solar sales conversations.

However, talking about sales competition in a conversation with potential customers requires careful consideration steel c profile manufacturer. This is especially true given the sensitivity of the topic and the fact that potential customers may not have been sold on solar energy itself, let alone who will install it. Wood Mackenzie reports that “solar companies are more likely to lose uncertainty and doubt than other competitors.”

The US solar industry is highly competitive

Consider the challenges customers get and avoid mistakes in conversations with potential customers, especially about how you discuss sales competition.

Choose the right time to drive sales competition

NREL researcher Ben Sigrin discusses the danger of criticizing competition before customers completely sell solar energy. The researchers acknowledged the need to “oppose competitors,” but claimed that “when solar potential customers are not fully involved in solar energy, doing so will not only hurt your competitors, but also hurt you.”

He suggested that understanding the various stages of the lead customer decision process can help contractors effectively cope with competition. He described the idea of ​​awareness and interest before the assessment process, when the client weighed the contractor’s choice.

Letting customers transcend the awareness phase means avoiding intimidation tactics. As West Green admits, “There is no doubt that trying to attract customers by inciting others with some good, old-fashioned FUD is tempting. – Fear, uncertainty and doubt.” However, in Using such a strategy in your sales strategy is more likely to scare away the prospects away from solar energy.

Understand the customer’s decision-making process

Research shows the value of understanding the customer decision stage. The underlying idea is that consumers make purchases at various stages in their sales conversations. The funnel is a useful metaphor for understanding how this process happens. This is because as consumers go through various stages, the number of viable customers will decrease. Selected products that reach the bottom of the funnel have evolved to the point where they can be purchased.sino east steel group co ltd

The stages associated with solar energy include: awareness (about solar energy and what it can provide), interest (the enthusiasm and/or feelings about solar energy ideas are feasible for them), decisions (assessing various suppliers) and actions (commitment) ) buy the system). The final stage is publicity (as a solar energy ambassador).

Try to find out where your potential customers are in your solar sales conversation. This can help you and your sales team members meet their needs and avoid any mistakes. This is especially useful given that potential customers may be talking from different angles.

What is galvanized steel z profile
