All about aluminum corner profiles

The aluminum corner profile is not intended for supporting structures. Its purpose is interior doors and windows, slopes of window and door openings, plasterboard partitions and other elements of the interior arrangement of the house. The challenge is to add strength, as thin wood and plastic break from impacts.

Corner aluminum profile is suitable for creating secure corners in structures where they are important, in order to give the correct geometry of the assembly. It is also used as a guide to create a kind of arched vaults from drywall, wood and other bending and piecemeal blanks. The corner profile, due to the fact that it is made mainly of aluminum, allows you to apply not too high a load - a maximum of tens of kilograms in the place (lines, points) of its fastening. This means that it is advisable to make assemblies that include this profile hollow, without filling the entire space inside with heavy material-intensive fillers. Aluminum profile in combination with plasterboard - an easy construction and maintenance.

The plasterboard corner profile has an angle of 85 degrees. The underestimation of the angle contributes to the most complete adherence to the drywall sheets - provided that the force of gravity exerted on the sheet and corner is not lower than a certain value. This value is calculated according to the laws of physics.

The aluminum profile is easy to saw at different angles: 45, 30, 60 degrees. The cut is selected depending on the assembly not of a round, but of a piece-wise compiled arch, bend. It is easy to process, but it cannot be bent when heated over gas - at a temperature of 660 degrees, aluminum immediately melts (becomes liquid).

The most popular aluminum profile corners are 25x25, 10x10, 15x15, 20x20 mm. The thickness of the walls can reach from 1 to 2.5 mm - depending on their width. In this regard, they resemble steel corners - thick aluminum, in comparison with steel, is at least twice as light, provided that the length, width and thickness of the components are the same.

The connecting (docking) corner is produced in the form of three-meter segments. The profile is sold individually or in bulk. The main casting profiles are L-, H-, T-, P, C-, U-, Z-, S-shaped, theoretically, casting is possible in a section in a shape that resembles any number or letter, an icon of almost unlimited complexity. According to GOST, the permissible thickness deviation is up to 0.01 mm / cm, the length error is less than a millimeter per linear meter.

The herringbone profile is a modified H-shaped cross-section, in which one side (the vertical of the letter-cut) is 30 percent shorter than the other. It is used as a separator in the expansion joint, as an auxiliary (framing) element (edging) of the self-leveling floor. Can be supplied as regular (no holes) or perforated.

A corner with holes, equipped with a reinforcing mesh, is used as a reinforcing element, for example, when arranging slopes and corners in window and door openings. Its protective layer allows not to disturb the plaster, conceived for the finishing project, fits in according to its requirements in the heat-insulating structures and layers. Thanks to the mesh, the plaster is reliably held where it would experience significant temperature fluctuations when the heating system is operating. The corner, complemented by a reinforcement mesh, is used for interior and exterior work when decorating country houses and commercial one-story buildings. The mesh coating does not suffer any negative effects when exposed to alkaline and salty environments. Such a profile will not lose its properties in 20-35 years.

Overhead inner aluminum profile - a substitute for polypropylene and hemispherical steel (floor, sectional) boxes.

Angle profiles made of aluminum are used in many main and auxiliary industries of decoration, arrangement of territories and premises, as an element of furniture, and so on. Here are some specific examples.

• For glass: using rubber gaskets and / or glue-sealant, possibly wooden and composite strips between the inner and outer glass, it is just right to assemble a self-assembled glass unit, which is not inferior in characteristics or quality to its industrial counterparts.

• For panels: decorative corner made of aluminum effectively and effectively complements panel blanks made of composite, plastic and wood, chip-adhesive sawn timber, preventing the ends from chipping, abrading, protecting the cut (edge) of the board or chipboard / OSB / plywood from the penetration of mold, fungus and microbes into the wood material ... The plastic around the edges does not chip or abrade, does not get dirty with intensive use.

• For tiles: aluminum and steel corners also protect the tile from chipping, cracking, isolating its sections from external destabilizing influences. Everyday dirt in a house or apartment, which could "blacken" the side edges of light marble or porcelain stoneware, facing tile glaze, do not get into these places.

• For steps: wooden, marble, reinforced concrete (with finishing) steps are also protected by the edges of the aluminum corner from the same damage. For example, it is easy to chop off stone, brick or concrete by rolling a laden trolley up or down stairs.

This list threatens to become endless. If for some reason the aluminum profile did not suit you, you can familiarize yourself with the assortment of plastic, composite or steel.
