Summary of aluminium profile uses

Aluminium profiles can be divided into 9 uses, namely: aluminium profiles for construction, aluminium profiles for radiators, aluminium profiles for industry, aluminium profiles for automotive parts, aluminium profiles for furniture, aluminium profiles for solar photovoltaics, aluminium profiles for rail vehicles, aluminium profiles for mounting and aluminium profiles for medical equipment. The sub-categories of these nine uses are as follows.

1、Aluminium profiles for construction
Aluminum profiles for construction include aluminum profiles for doors and windows and aluminum profiles for curtain walls, such as aluminum profiles for roofing in buildings. Walls. Doors and windows. Interior and exterior decoration, construction formwork, composite doors and windows, composite aluminum panels. Coloured aluminium sheets, aluminium alloy formwork, etc. Aluminium profiles for construction have beautiful colour, good corrosion resistance, good reflectivity of light and heat, and good sound absorption.

2、Heat sink aluminium profiles
Heat dissipation of various electronic equipment, heat dissipation of lighting fixtures, and hoods for heat dissipation of computer digital products.

3、Industrial aluminium profiles
Mostly used in mechanical automation industrial production industry, such as automatic machinery and equipment, assembly line workbench, equipment machine cover, equipment rack fence, non-standard aluminum profile frame, aluminum profile conveyor belt, aluminum profile whiteboard shelf, operating table, workshop partition, shelf material shelf, mobile cart, aluminum profile high walking platform stepping platform, etc.

4、Aluminium profiles for auto parts
Mostly used for auto parts, connectors, assembling external frames, etc.

5、Furniture aluminium profiles
Used for home furnishing furniture, furniture decorative frame, aluminium profile fish tank, bed, table and chair support frame, etc.

6、Solar photovoltaic aluminium profiles
Used for solar energy frame, photovoltaic bracket, solar photovoltaic fastener parts and so on.

7, rail vehicle aluminum alloy profile
Mostly used for making the body of rail vehicles.

8、Mounted aluminium alloy profiles
Decorative picture frames, exhibition framing, outer frames of decorative paintings, etc.

9、Aluminium alloy profiles for medical equipment
The main frame of medical equipment, medical instruments, medical stretcher bed frame, etc.

National standard for powder coated 6063-T5 industrial aluminium profiles

Grade and condition 6063 T5
Standard No. GB5237.4-2008
The quality of the base material should be in accordance with GB5237.1-2008 dimensional tolerance should be in accordance with GB5237.1-2008
Mechanical properties ﹑ after removing the coating should be consistent with the provisions of GB5237.1-2008 chemical composition after removing the coating should be consistent with the provisions of GB5237.1-2008.
Requirements
Colour and colour difference
The colour of the coating shall be the same as the sample agreed between the supplier and the customer. When using the colour difference meter, the colour difference between the monochrome coating and the sample shall be △Eab`≤1.5, and the colour difference between the profiles of the same batch (referring to the delivery batch) shall be △Eab`≤1.5.
Coating thickness
Minimum local thickness on the decorative surface ≥ 40u m indentation hardness
Indentation resistance of the coating ≥ 80 adhesion
The dry adhesion, wet adhesion and boiling water adhesion of the coating should reach the OO level of impact resistance
No cracking or peeling of the coating after impact testing.
If the supplier and the customer agree to use a coating with certain special properties but with a slightly lower impact resistance, a slight cracking of the coating after the impact test is allowed, but when using adhesive tape for further inspection, the surface of the coating shall be free of sticky fall. Resistance to cupping
No cracking or peeling of the coating after the cupping test.
When the supply and demand sides agree to use a coating with some special properties but slightly less resistance to cupping, the coating is allowed to crack slightly after the cupping test, but the surface of the coating should not be sticky when it is further tested with adhesive tape. Bending resistance
In the bending resistance test, the surface of the coating shall be free from cracks or peeling.
When the supply and demand sides agree to use some special properties and bending resistance of the coating is slightly less, the bending resistance test allows the coating to have a slight cracking phenomenon, but when using adhesive tape for further inspection, the coating surface should not be sticky. Appearance quality
The coating on the decorative surface of the powder-coated profile shall be smooth and even, and no wrinkles, flow marks, bulging, cracks, stickiness and other defects affecting the use are allowed. A slight orange peel is allowed, the permissible degree of which shall be indicated by the physical specimen agreed between the supplier and the demander.

What are the implementation standards for aluminium profiles?

As a modern industrial manufacturing country, made in China is a label that can be seen all over the world. The quality control of products is therefore particularly important, so there are different standards for different product categories. Domestic standards are commonly known as national standards, while European standards are commonly known as European standards. So what are the executive standards for aluminium profiles? Today we will take an inventory of.

1, the executive standard of architectural aluminum profiles: GB/T5237-2017 is the total executive standard, GB represents the national standard, T represents the recommendation. There will be GB5237.1, GB5237.2, etc., which are the specific implementation standards for different surface treatments. GB5237.3-2017 is the implementation standard for electrophoretic painted architectural aluminum profiles.

2, general industrial aluminum profiles executive standard: GB/T6892-2016, this standard is applicable to the executive standard of aluminum alloy extrusion profiles other than architectural curtain wall aluminum profiles, civil and decorative aluminum profiles, the executive standard of general industrial aluminum profiles is not as strict as architectural aluminum profiles, Hongfa non-ferrous are to architectural aluminum profiles standard to industrial aluminum profiles quality control.

3, non-building aluminum alloy decorative profiles executive standard: GB/T26014-2010, this standard is applicable to decorative-based hot extrusion profiles, the surface quality requirements are relatively high, the mechanical properties, shape and position tolerance requirements are low.

4, Aluminum and aluminum alloy profile size deviation: GB/T14846-2014, this is another implementation standard for industrial aluminum profiles, but this standard only controls the profile size of aluminum profiles, other requirements or according to GB/T6892-2016. So this implementation standard is used less.

Of course, in addition to the national standard, there are also some foreign implementation standards. European Union EN12020-26060 and 6063 aluminium and aluminium alloy precision profiles part 2: “size and shape allowable deviation”, EN755-2 “aluminium and aluminium alloy bar, tube, type – mechanical properties”, the United States ANSI H35.2 “United States aluminum material size deviation standard” and Japan JIS H4100 “Aluminium and aluminium alloy extrusion profiles” and other standards, applicable to export profiles.
