What it is?

A component of the enclosing structure’s supporting frame, the galvanized wall profile for plasterboard is made of sheet steel that has been coated in a layer of zinc through the process of coordinated punching and cold deformation.

Through the mutually orthogonal arrangement of vertical and horizontal profiles, these structural elements are installed between the floors within the room, forming a cell with typical dimensions ranging from 400 x 400 to 600 x 600 mm.

How is it different from aluminum?

Galvanized profiles have several differences from aluminum ones, which are also often used in the construction of partitions from gypsum plasterboard:

• Appearance – galvanized profiles, as a rule, have an uneven shade and a rough front surface, while aluminum products have a smooth surface and an almost mirror-like shine. This feature has little effect on consumer demand, since the racks and imposts of the frame are masked in the body of the partition.
• The aluminum profile is covered with an oxide film in natural conditions, and the galvanized coating is arranged when organizing the appropriate technological process – galvanizing.
• Aluminum products are considered more difficult to install, since they are fixed exclusively with rivets placed in pre-drilled holes.
• The thermal conductivity of aluminum, as well as the coefficient of linear expansion, is significantly higher than that of galvanized steel, which often leads to deformation of the partitions if they are operated at low temperatures.

Products made of non-ferrous metals are much less in demand than galvanized ones because the primary distinction between aluminum and galvanized profile elements for the construction of partitions is their retail cost, which can vary by at least two to three times.

Features of the composition

The following parts and supplies are used in the production of galvanized profiles for plasterboard partitions in compliance with GOST 14918–80 requirements:

• Black alloy steel, consisting of iron, with the addition of carbon 1.8% – 2.0%
• Zinc, which is applied hot or cold by lowering the sheet into a bath of molten material.
• Alloying additives that increase the mechanical strength of the sheet – tin, titanium, copper, lead, no more than 0.5% – 1.0%
• Chemical elements that increase the corrosion resistance of the material – silicon, phosphorus, sulfur with a mass fraction from 0.1% to 0.4%.

The partition’s load-bearing frame’s durability, chemical resistance, mechanical strength, and dependability are all greatly impacted by the quantity and kind of alloying additives used. Every manufacturer affixes a quality passport to each batch of products it produces, detailing every component that goes into the product as well as the technical specs and mechanical and physical attributes of every profile element.

Requirements

GOST 24045-2016 and GOST R 58389-2019 set requirements for galvanized profiles for partitions. These standards govern the following required product attributes:

• Compliance with GOST requirements.
• Ensuring mechanical strength described in the quality certificate based on test results.
• Deviation from modular dimensions in length and cross-sectional dimensions is no more than 0.1% – 0.2%.
• Surface quality – there should be no foreign inclusions, dents, chips or other signs of defects on the walls and shelves of the profile.
• Anti-corrosion resistance in humid and chemically active environments.
• The minimum steel thickness for the rack profile should be from 0.5 mm.
• Profile elements should not lose stability and load-bearing capacity under the weight of plasterboard sheets, as well as when applying permanent or temporary loads.
• The cross-section of the structural element must ensure the overall strength and stability of the gypsum plasterboard partition frame.

Based on the aforementioned GOSTs, each officially recognized manufacturing company creates its own specifications. Following the manufacturing of a batch of goods, sample samples are put through extensive testing on laboratory benches. Following this, the product is given a certificate of conformity, which attests to its high quality and compliance with legal requirements.
