How to Select China Aluminum Profile Suppliers

Haomei suggests that you should select China aluminum profile suppliers based on the following aspects: brand, production batch, production line, ingot quality, bridge quality of broken bridge profiles and quality prizes of national level. Brands are relatively stable, for there are only several famous brands of each type of aluminum profiles, which you can have a general idea just by surfing the internet. We will focus on the other five parts.

Production batch also refers to production factory here. Many big China aluminum profile suppliers have main workshops and branch factories. Generally speaking, a branch factory can not compete with the main workshop in management, which leads to reduction in product quality. Therefore, not all suppliers of good brands supply superior profiles. Production line refers to the advance level of equipment and process applied to produce the wanted aluminum profile. Take the surface treatment for example. Vertical treatment has better effect than electrophoresis, because it produces a more uniform surface. The importance of ingot quality is universally acknowledged. Make sure that your supplier use pure aluminium ingot rather than ingots made of recycled aluminum products. With aluminum extrusion of broken bridge series, the quality of bridge in the middle proves to be crucial. The bridge usually has a different expansion&shrinkage rate from its profile. Good bridges help extrusions last decades without breaking, and there are huge price gaps between inferior and superior bridges.
Quality prize part is worth elaborating, because most foreign purchasers learn little about this in China. Do not be excited for finding a reliable supplier when you receive a bunch of prize pictures with Chinese characters on them. The fact is, the words like “national famous brand” or “renowned commercial mark” is no big deal for any China aluminum profile supplier with a certain scale. The really valuable prize is related to quality rather than price or sales quantity. Therefore, just check what quality prizes a supplier has.

Slitting of 1mm 2mm 4mm aluminium strip

What kind of machine is used to make aluminum sheets into 1mm 2mm 4mm aluminium strip belts? Many people might think about a shearing device, but they are actually dealt with by a continuous slitting unit of a similar working principle to that of a shearing device. The difference lies in the point that there is no pause of shearing with a continuous slitting unit. Generally, the mother roll, namely, an  aluminum coil  to be slit, is placed. During the slitting process, the coil roll is divided into several belts which are further rolled into narrow aluminium strip rolls. The slitting method of both  1mm 2mm 4mm aluminium strip  or other aluminum strips can be divided into two types: a straight pull type and a loose sleeve type. The straight pull type refers to the method that aluminum strip rolls are kept in tension from being fed into the unwinding sail to being coiled by the coiling machine, and this production method is suitable for trimming and intermediate slitting. The loop

Diamond Embossed Aluminum Sheet Application

The  diamond embossed aluminum sheet  refers to aluminium sheets with diamond patterns on the surface. In addition to 1000 series, 5005 and 3003 are frequently applied alloys as well. 5005  diamond embossed aluminum sheet s can be used for conductivity materials, cookware, instrument panels, electronic shells and building ornaments. Their anodized film proves to be brighter than that of 3003, and the color matches perfectly with that of 6063 aluminum alloy products. Generally speaking,  diamond aluminum checker plate s are sold by the unit of pieces. In international business the unit of metric ton is frequently used as well. Their thickness ranges from 1.7mm to 8mm, but those between 2mm and 7.75mm prove to be the most popular. The width is from 1010 to 1500, among which 1250 and 1500 are most frequently adopted. Embossed aluminum sheet s with different patterns usually match varied application scope. Five-bar and one-bar sheets are mostly used for anti-skid purposes as tread pla

If you have ever used an escalator you might have noticed that there are partition panels respectively at the bottom and top of the escalator. These partitions are usually paved with  embossed aluminium sheet  coil that have a good pressure bearing capacity and are made of composite metals. As a matter of fact, there are various patterns and applications of embossed aluminium coil, and here we will give a simple introduction. 　　Patterns 　　Aluminum sheets with patterns on the surface is called embossed aluminum sheets or  aluminium tread plate . Pattern shapes include lentils, diamonds, round beans, and oblate mixed shapes. The market is most common in lentils. 　　Application 　　The aluminium tread plate has beautiful appearance, excellent anti-slip property, enhanced performances, and material-saving advantage in production. It is widely used in transportation, construction, decoration, equipment, floor, machinery, shipbuilding and other fields. Generally speaking, clients requi
