Aluminium Roofing Sheet Thickness and Classification

The aluminium roofing sheet has a simple structure, and the sheet is continuously bent and formed by a green frame building material bending machine, and a decorative paint can be sprayed on the surface thereof. Because of its good plasticity, aluminium roofing sheet can better adapt to the requirements of various architectural styles with beautiful appearance, good color durability and excellent environmental effect.
　　Thickness of Aluminium Roofing Sheet:
　　Regular thickness offered by aluminium sheet suppliers are 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm and 5.0mm. These specifications are similar to those of aluminum veneers. Some purchasers order thinner sheets in pursuit of lower cost and generally buyers can customize thickness to meet varied market and application needs.

　　Classification of Aluminium Roofing Sheet:
　　Aluminium roofing sheet is usually classified according to application areas, plate type wave heights, lap joint structures and materials. The common classification methods are as below:
　　(1) According to the application part classification - divided into roofing panels, wall panels, floor panels and ceiling panels. In the use, the color coated aluminium roofing sheet is used as the wall decoration board, and the architectural decoration effect is relatively novel and unique.
　　(2) According to the wave height classification - divided into high wave plate (wave height ≥ 70mm), medium wave plate (wave height <70mm) and low wave plate (wave height <30mm)
　　(3) According to the material classification of the substrate - it is divided into hot-dip galvanized substrate, hot-dip aluminum zinc and hot-dip galvanized aluminum substrate.
　　(4) Classification according to the seam structure - divided into lap joint, undercut and buckle structure. The middle and high wave plates with undercut and buckled should be used as roof panels with high waterproof requirements; the galvanized plates with overlapping middle and high wave plates are used for floor coverings; the lapped low wave plates should be used as wall panels.

Slitting of 1mm 2mm 4mm aluminium strip

图片
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.

Embossed Aluminium Coil Patterns And Applications

图片
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

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
