1. Aluminum alloy door and window profile specifications mainly include: 35 series, 38 series, 40 series, 60 series, 70 series, 90 series, etc.
2. The so-called 35 and 38 refer to the width of the main frame of aluminum alloy profiles, which are 35mm and 38mm respectively.
3. The size of aluminum door and window profile is mainly marked by the height of profile section (the thickness of door and window frame used in aluminum alloy doors and windows), and constitutes a size series. The size series of aluminum alloy windows are smaller, while the size series of aluminum alloy doors are larger. The size series of aluminum doors and windows are the same, not necessarily the section shape and size of aluminum doors and windows are the same.

Corrosion Resistance
The density of aluminum profile is only 2.7g/cm3, which is about 1 / 3 of that of steel, copper or brass (7.83g/cm3 and 8.93g/cm3 respectively). Aluminum exhibits excellent corrosion resistance in most environmental conditions, including in air, water (or brine), petrochemical and many chemical systems.
Conductivity
Aluminum profile is often used because of its excellent conductivity. On the basis of equal weight, the conductivity of aluminum is close to half of that of copper.
Thermal Conductivity
The thermal conductivity of aluminum alloy is about 50-60% of that of copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, as well as the cylinder head and radiator of automobiles.
Non Ferromagnetism
Aluminum profile is non ferromagnetic, which is an important characteristic for electrical industry and electronic industry. Aluminum profiles are not self ignitable, which is important for applications involving handling or contacting flammable and explosive materials.
Machinability
The machinability of aluminum profile is excellent. In all kinds of wrought and cast aluminum alloys, as well as in all kinds of states of these alloys, the machining characteristics change greatly, which requires special machine tools or technology.
Formability
Specific tensile strength, yield strength, ductility and corresponding work hardening rate control the variation of allowable deformation.
Recyclability
Aluminum is highly recyclable, and there is almost no difference between recycled aluminum and primary aluminum.
1. There are many varieties and specifications. There are more than ten thousand kinds of products. In the production, except for a few special mills, most of the rolling mills are producing many kinds and specifications.
2. The shape of the section is different. In profile products, except for the simple and small difference in the shape of square, round and flat steel sections, most of the complex section profiles (such as I-beam, H-shaped steel, Z-shaped steel, channel steel, rail, etc.) are not only complex in shape, but also different from each other. The design of pass shape and rolling production of these products have their own particularity.
3. The complexity of the section shape makes the deformation of each part of metal, the temperature distribution of the cross section and the wear of the roll uneven during rolling. Therefore, the size of the rolled piece is difficult to calculate and control accurately, and the adjustment of the rolling mill and the installation of the guide guard are also complex.
4. In addition, the single type or specification of complex section profile is usually small in batch. The above factors make the development of the continuous rolling technology of complex section profile difficult.
5. There are many rolling mill structures and mill arrangement forms. In terms of structure, there are two high rolling mill, three high rolling mill, four high universal pass mill, multi roll pass mill, Y-type mill, 45 ° Rolling mill and cantilever mill, etc. In the layout of rolling mill, there are horizontal rolling mill, tandem mill, checkerboard mill, semi continuous mill and continuous rolling mill.
Q – What is the average lead time for pre production samples?
A – Our average lead time is normally 7 days for making new samples and 7 days for testing , totally need about 14days.
Q – What is the average lead time for mass production?
A – Our average lead time is delivery within 20-30 days after receive deposit and and moulds/samples are passed.
Q – What is CAD?
A – CAD stands for “computer assisted design” and it is a 3-D program that is used by our clients to provide our technicians with a three-dimensional example of the custom shape that they want made at GUANGDONG YONGLONG ALUMINUM.
Q – What is a die?
A – A die is a tool that is used to help forge a custom shape during the extrusion process. The die is made from durable steel so that it can be used again and again to fill the client’s order.
Q – What does extrusion mean?
A – Extrusion is the process that is used to create custom shapes from raw aluminum materials according to a client’s specifications. The raw materials are heated and are then forced through a die to create the desired shape using extreme pressure.
