How to Choose China Authentic Supplier of Aluminium Profile?

How to Choose China Authentic Supplier of Aluminium Profile?

Industrial aluminum profile processing
Industrial aluminum profile is extruded through high-temperature solution and hot extrusion, the cross-sectional shape is directly molded by extruding the die, the production process is relatively simple. The aluminum extrusion profiles can process sawing, drilling and milling, bending, welding, and various shapes of aluminum profiles can be mutually assembled. In addition, they can be produced in different grades according to the load-bearing and mechanical strength requirements.

Features of industrial aluminum profiles
Industrial aluminum profiles are broadly used, and highly versatile. They are lightweight, good heat dissipation, high productivity and environmental protection, which have become the first choice for industrial materials. Industrial aluminum profile surface can process a variety of styles treatment, such as oxidation (gray, black, sand blasting, drawing, etc.), and can also be painted, sprayed, chrome polished, which are nice and can improve product added value. Pass SGS environmental protection test.

How to choose China authentic supplier of aluminium profile? There are three principles to choose aluminum profile suppliers:

1. Do not choose the supplier whose products are very cheap
Aluminum profile cost = ingot spot price + processing cost for extruding aluminum +packaging materials + shipping fees. These are very transparent, the costs of aluminum profiles are similar, the first possibility for the significantly lower price than the market is weight per meter is less; second: aluminum ingots using recycled materials; Third: enlarge cutting losses (not sell by the actual number of meters).

2. Not choose the suppliers who only know how to sell the material
Prepare some shipment, recruit a few operators, and open by wantonly marketing online, these tend to hurt the buyers. Most operators do not understand how to use, they just know the price. How to use to meet customer demand? How to make to be cost-effective? Which connection way is the best in different places? They are unable to accurately answer. They only know to recommended the cheapest profiles and the cheapest connection way; This connection way is the lowest cost, but the most labor-consuming, but also the worst kind of connection, the convenience of aluminum profiles would not be reflected, and will bring relatively large trouble for the renovation later.

3. Choose the production-based aluminum profile supplier
The production-based aluminum profile suppliers are generally engaged in this industry for over 10 years, and they are also users themselves. They have a wealth of practical experience, and have a very good understanding and knowledge about product quality and performance, which will recommend better cost products appropriate for customer needs, and choose convenient and practical accessories.

Why are Container Houses more and more Popular?

Container house brings convenience for life
Container house is another building system striking fashion trend, which can be moved anywhere anytime, bringing more convenient comfortable life for people. The traditional housing concepts are outdated, which also inspires people's new reflect on self living space. Using containers to build a house is one of the new idea, it is green, time and effort saving, very flexible, and can provide more housing choices compared to traditional homes, personal, family, or even a community can take what they need. A house made of steel box can also be full of fashionable breath, and very environmentally friendly.

Container house can be combined into different structures
The principal part of container house is the container shaped container houses, these container houses have similar structures and dimensions are also similar, which can easily be combined into a variety of different structures, different styles of buildings. Meanwhile, the appearance of the container housing can also change, being made into different colors, different patterns of appearance models, which allows container houses to be more fashionable. In addition, the interior decoration of cheap container house can play for free, being made into a variety of different styles of interior styles in line with your requirements. The internal part of the container housing can be added with the different components to meet the needs of everyday life, and a few monomer container houses can be connected together to form a larger room.

The container house is a kind of housing gradually becoming popular in the current society, which has been extremely popular in some developed countries. Due to easy to transport and lower cost, the market prospect of container houses is very good. What are the characteristics of this housing compared with the traditional houses?

First, since container house adopts a skeleton system, its structure is very safe and reliable, solid and strong. Secondly, container house has a good anti-seismic wind proof capacity, so it can be well used in some emergencies, such as earthquakes, etc. In addition, the container house has overall transport characteristic, which can be directly transported after being processed in the factory and the internal water configuration is also very complete. The water resistance, heat resistance and sound insulation performance is very obvious, and this also explains the difference between container homes in south africa and general housing is not great, comfort is higher. More importantly, the container house has a recycling characteristic, and its life is also very long, which generally lasts 20 years, very practical.

Container houses have rugged structure, green and energy-saving, the manufacturing process does not produce construction waste, which can be recycled and reused. These features meet people's pursuit for the protection of environment, and conservation of resources, so container houses are more and more popular.

How to Calculate Power Bank Capacity?

The best tool to detect the true power bank capacity is to use our phones as the measure standard. I believe this is what we are most concerned about, which what you are most concerned about when buying power bank! First, we need to understand relationships between the power bank and the charger devices.
1. We must first know what measures the charging indicator of power bank corresponding to cell phone. It should be moving power of power bank: power = voltage * current. Cell phone batteries will usually directly be marked with it, the voltage of most phones is 3.7V, and the power will be marked on the phone battery!
2. How much is the power bank conversion rate?
The batteries of power bank are 3.7V output, first boost to a maximum of 5V through the internal circuit control, and then charge for the phone output, so there is a certain conversion rate during the product buck-boost. Generally, the qualified power bank conversion required in this process is designed about 90%. Power bank conversion rate is also related to batteries used in the production. The polymer rechargeable batteries work output conversion rate is generally 85% -95%, and 18650 lithium battery output conversion rate is 75% - 85%. In summary, the overall conversion rate of power bank, the power bank conversion rate of better batteries produced by polymer batteries is 75% - 85%, and the conversion rate of power bank produced by 1865 batteries is 65% -70%.

3. Whether the power bank capacity the seller tell you is true
Many manufacturers will label larger power bank capacity in order to drive down the price and increase the shipment volume, and some will even have a lot of difference!
4. Test conversion rate, the real capacity and charging times
After we know the real capacity of power bank, we should begin calculating the charging times of mobile phone. The current of general smart phones required at charging is dynamic, normally above 500MA-1000MA, the voltage is at 5V or so. If the battery power is marked 3Wh, then the power of a 4000 mA power bank should be 4 * 3.7 = 14.8W, calculate by our polymer batteries conversion rate of 80%, the real total power supply for charging can be 11.8W. Take a 1500mA smart phone for example, the demand power is 3.7*1.5 = 5.55W, then it can charge the phone two times. Of course, Apple 4S phone is 1400 mA, 4.2V, then it needs 1.4 * 4.2 = 5.8, which is able to charge two times.
If practical power bank can charge the phone for 2 times, you will need large-capacity power bank to charge your tablet, the power bank capacity should be more than 8000MA, and can provide high current 2A output charging requirements (dual USB power bank)!
