Topic	Description
What is a rack profile for plasterboard?	A rack profile is a metal frame component used to support plasterboard in walls and ceilings. It"s essential for creating sturdy and straight surfaces for finishing.
Installation rules	Ensure the profiles are cut to the correct length, fixed securely to the floor and ceiling, and aligned properly. Use screws or appropriate fixings and double-check the level before attaching plasterboard.
Difficulties	Common challenges include ensuring profiles are perfectly vertical, dealing with uneven surfaces, and securely fixing profiles in place. Accurate measurement and careful handling are crucial to avoid issues.

What is the product?

The primary structural component of the supporting frame of the volumetric-planning element is a rack profile for a plasterboard partition. The profile is firmly fixed in a vertical position to the starting guides that are situated in the upper and lower portions of the floor slabs.

The purpose of the rack profile element is to guarantee the bearing capacity of the enclosing structure and to withstand external permanent and temporary loads applied to the partition during the operation of the premises.

Purposes of use

The most crucial component of the gypsum board partition’s supporting frame, the rack profile serves the following purposes:

• The load-bearing part of the partition frame, the perception of external loads with their subsequent redistribution through the starting profiles in the floor slabs.
• Formation of a cell with a certain pitch for subsequent fastening of the cladding elements of the building envelope.
• Basis for fastening horizontal imposts, lintels for strengthening window or door openings, decorative niches.
• Ensuring a vertical alignment of the structure due to reliable fastening at two extreme points to the starting guides.
• The basis for installing thermal insulation in the body of the future partition.
• Element for fastening hidden electrical cables and pipe communications, if these solutions are included in the project.

It is advised to create a thorough partition design that includes the development of the supporting frame and a thorough specification of every component when determining the quantity of a rack profile. This practice minimizes waste and eliminates material waste.

Requirements

The following regulatory documents govern the requirements for load-bearing rack profiles used in the construction of enclosed structures made of gypsum plasterboard sheets:

• GOST R 58389-2019 “Bent steel sheet profiles with trapezoidal corrugations for steel-reinforced concrete structures”.
• GOST 6266-97 “Gypsum plasterboard sheets”.
• GOST 24045-2016 “Bent steel sheet profiles with trapezoidal corrugations for construction”.
• SP 163.1325800.2014 “Structures using plasterboard and gypsum fiber sheets. Rules for design and installation".

The following requirements must be fulfilled by all rack profile elements in accordance with the points of these standards:

• Ensuring load-bearing capacity.
• Minimum deviations from the specified geometry.
• High surface quality, absence of dents, traces of mechanical damage, burrs along the entire length of the element.
• Uniform surface shade, which indicates the high quality of galvanized coating.
• Corrosion resistance – the galvanized layer must protect the products from rust along the entire length and at the ends of the shipping mark.
• The profile must have stiffening ribs with a depth of at least 2 – 3 mm.
• In the places where the rack is supposed to interface with the horizontal impost, holes are made using coordinate-punching equipment.
• Resistance against general deformations and local crushing under design loads over a span of 2.5 to 4 meters, without the need to install reinforcing elements.

A lot of manufacturing companies create their own albums of standard solutions and technical documentation (TS), which are used as a foundation for designing rack profiles as they are manufactured. Prototypes from each new batch of products are tested in a lab setting after they are released, and the results are used to create protocols, quality and conformance certificates, and certificates of sale for the products.

Markings and technical specifications

All certified products in the relevant category that are meant to be used for zoning purposes or for the installation of gypsum plasterboard interior partitions have the following technical features:

1. Marking: PS (rack profile).
