Aluminum square 26х26 mm D16T is a standard general-purpose aluminum profile that has found application in a wide variety of industries, manufacturing, and construction. The product is an aluminum rod, the cross section of which is made in the form of a square. Products are presented in a wide variety of sizes, may differ in the type (composition) of the alloy used for the production, the presence or absence of additional processing and coating. Sometimes an aluminum square can be supplemented with an internal hole (square tubes).
Rectangular aluminum bar is a versatile material used for various purposes. Depending on the purpose, the rod can be additionally protected with an anodizing coating. Such products have an attractive appearance and are reliably protected from moisture and corrosion. By heat treatment, the aluminum square is made stronger while maintaining good elasticity and flexibility.
Sometimes aluminum squares are coated with an anodized coating, which gives an aesthetic appearance and permanently protects against the corrosive effects of the external environment, especially moisture. The heat treatment of the aluminum square gives this profile strength, leaving enough elasticity for comfortable bending. Squares AD31 are subjected to artificial aging and incomplete hardening.
An aluminum square is an all-metal bar made of aluminum or an aluminum alloy, which has a square cross section. They are produced according to GOST21488-97.
Aluminum squares are divided into:
1) according to manufacturing accuracy:
normal accuracy,
high precision,
high precision;
2) according to the condition of the material:
without heat treatment (hot-pressed),
soft (annealed),
hardened and naturally aged,
hardened and artificially aged;
3) by type of strength:
normal strength,
increased strength.
4) by length:
unmeasured - without designation;
measured - indicate the specified size.
The size of an aluminum square is determined by the diameter of the circle inscribed in it.
Choose and buy an aluminum square that are made from aluminum grades AD0, AD1, AD and aluminum alloys grades AMts, AMtsS, AMg2, AMg3, AMg5, AMg6, AD31, AD33, AD35, AB, AK4, AK4-1, AK6, AK8, 1915 , 1925 with a chemical composition according to GOST4784, aluminum alloys of AKM grades with a chemical composition according to GOST1131. By agreement between the manufacturer and the consumer, it is allowed to produce squares from aluminum of other grades of high and technical purity in accordance with GOST 11069.
The surface of the square should not have cracks, delaminations, non-metallic inclusions, stains of corrosive origin and traces of saltpeter. On the surface of the squares are allowed:
captivity, nicks, dents, scratches, risks, single bubbles, various kinds of pressing, if the depth of their occurrence does not take the bar beyond minus limit deviations in size;
tint colors, dark and light spots and stripes, including ring-shaped and spiral-shaped, which are traces of editing.
The microstructure of the square should not have cracks, choose and buy aluminum pipes at a price of low looseness, delamination and sinking. The microstructure of the hardened squares should not show signs of burnout.
On the macrostructure of squares, the following are allowed:
non-metallic inclusions in the form of dots with a size of not more than 0.5 mm or in the form of strokes with a length of not more than 3 mm, if their number does not exceed:
2 pcs. — for bars with a diameter up to 50 mm,
3 pcs. — for bars with a diameter over 50 to 300 mm,
5 pieces. — for bars with a diameter over 300 mm;
intermetallic compounds on bars of AMg5 grade alloy with a size of 0.5 mm in an amount of not more than 5 pcs., and on bars of AMg6 brand alloy with a size of not more than 0.1 mm in the form of single scattered dots;
coarse-grained rim partially or around the entire perimeter, the value of which is not limited;
surface defects with a depth within the established limit deviations.
The aluminum square has found its application in shipbuilding, aircraft and mechanical engineering. In addition, an aluminum square is used in the manufacture of furniture, in construction and interior decoration, as well as to create an interior.
What are the benefits
Before choosing a square, it is necessary to clearly understand that it is used as a fundamental element of load-bearing structures, which is due to increased strength indicators. This was made possible through the use of modern production technology.
The main advantages are considered to be:
increased corrosion resistance;
excellent mechanical characteristics;
increased level of plasticity;
excellent strength indicators during direct compressive or bending load;
high thermal conductivity;
light weight of the final structure;
availability - an aluminum square is available due to low cost.
Together, this allows us to talk about the expediency of buying aluminum squares for solving numerous problems.
Aluminum typessquares
A wide range of specialized construction profiles is presented on the domestic market. A distinctive feature is not only the dimensions, but also the varieties of the alloy used with the production method. Do not ignore the profile with an additionally applied protective coating.
Depending on the scope, in addition to solid ones, there are also specialized aluminum squares with pre-formed holes, with a round or square section.
In the presence of increased humidity indicators, an anodizing treatment is additionally performed. This allows a significant improvement in the external design and also provides maximum protection against corrosion.
Thanks to specialized heat treatment, it is possible to significantly increase the strength indicators, and without any change in the level of plasticity. As a result, this ensures the flexibility of the bar. To choose the best option for yourself, it is advisable to contact a specialized company. This will give you an excellent combination of price and quality. Numerous reviews are this confirmation.

The microstructure of the square should not have cracks, ripples, delaminations and sinkholes. The microstructure of the hardened squares should not show signs of burnout.
The aluminum square is supplied in unmeasured and measured lengths. It complies with GOST 21488-97. According to the standard for a square section of bars, the diameter of the inscribed circle is normalized, more often it is 8 - 200 mm. This diameter is proportional to the side of the square. The maximum length is 6 m.
The material is characterized by environmental friendliness, durability, corrosion resistance, lightness, machinability, good conductivity, ductility. The aluminum square is non-magnetic, available, cheap. This explains the demand for products in radio engineering, aviation, machine and instrument making.
The square can be hardened, aged, annealed; released with conventional and increased manufacturing precision and strength. The surface of square bars may include minor defects. Supplied square bars in batches. Necessary protection and marking required.
Aluminum squares are used in many industries and households, namely: construction, design, electrical engineering, electronics, used in the construction of spacecraft, etc. Uncoated squares are subject to argon arc welding. Due to the elasticity of the AD31 alloy, bending an aluminum square on special equipment is easy and fast. Such rods can be machined without complications.
