Aluminum Extrusions

Otalum is one of the leading manufacturers of customed aluminium extrusion products in Southeast-China, Australia, South America and Southeast-Asia, offering a wide range of production capacities in aluminium extrusions, finishing and fabrication. Aluminium is a material combining the characteristics of light, strong, anti-rust, recyclable and economical, which provides the designers and manufacturers with precious choices to maintain a balance between function and cost.


Otalum’s aluminium extrusions profiles are mainly used for a wide variety of markets and applications, such as building and construction, machinery, automotive, furniture, LED, heat sink. These aluminium profile sections not only offer good functions but also perform well during actual use. All our extruded profiles can be produced with the processes of mill finish, anodizing, powder-coating, PVDF painting and wood finishing. Thermal break profiles are also available at Otalum and we also offer a full range of fabrication processes.


Types of Aluminium Extrusion

Various types of aluminum extrusion profiles can be created with different thicknesses. These extruded profiles can have a variety of complex void spaces, which are necessary for end-use applications. In order to facilitate various automation applications and meet any performance and weight requirements, a variety of internal voids can be used. The most common type of aluminum profile is hollow beam profile, which is just a variation of square profile. There are other contour types, such as triangular, single radius and L-shaped contours.


Aluminium Construction Profiles

Building & Construction is always the main market in the aluminium extrusion sections industry. In this area, Otalum offers a one-stop solution, including profiles design, die development, extrusion, finishing, fabrication and installation. We have an experienced team to arrange the whole process, ensuring the final outcome can totally meet your requirement. We also carry a wide range of dies for construction aluminium extruded products. All requests are made to order. Please, specify alloy, temper, length, quantity, surface finish, end-use and any special instructions regarding tolerance, delivery, packing and certification when ordering.


Industrial Aluminum Profile

Industrial markets are another big part of our business. We supply many big-scale manufacturing companies in the areas of machinery, equipment, electrical and automotive with first-class extrusion capacity, all kinds of surface finishing and fabrication services.


Standard Aluminum Extrusion Shapes

Standard aluminium profiles are the most basic products in the business. We offer a wide range of choices of angles, tubes, bars and U-channels with the standards of different countries, covering almost all the common use.


Aluminium Extrusion Uses

Aluminium extrusion transforms aluminum alloy into a variety of products suitable for consumers and industrial markets. Aluminum profiles have many uses in electronics, automobiles, public transportation, bridge deck paving, telecommunications, solar energy, renewable energy and other industries.


The extrusion process makes full use of the excellent ductility of aluminum. The aluminum alloy billet is heated to soften it, and then pressed into a special steel mold with a hydraulic press or a punch under high pressure to form a shape. The result is an aluminum sheet that maintains the specific shape of the mold.


Aluminum Extrusion Alloys

Different alloys in different states can make extruded aluminum profiles to meet the various needs-from household items to space vehicles. Basically, aluminum profiles can be extruded from any deformable aluminum alloy (even casting) in one way or another. However, metals need special flow characteristics to flow through the holes and cavities of the matrix under high temperature compression. Therefore, metals should: fill all the holes at the exit of the matrix at the same high speed, provide the required micro-structure, reach the predetermined strength and other characteristics and shape the best surface quality.


Therefore, special aluminum alloys specifically for pressing (extrusion) are being developed. In this way, the chemical composition of these alloys is optimized to make them most suitable for the conditions of the pressing process and to ensure the required quality of the molded products.
