To work with drywall, you must purchase the required type of profile. The master must understand exactly what kind of guides he will need. The profile allows you to create structures of varying complexity. From drywall, you can mount them on the wall or ceiling. The frame element, selected correctly, allows you to get a solid structure. What is the starting profile for drywall, what are its features, will be discussed later.
Definition
The profile on the wall under the drywall is made using special technology. Structural elements of this type are made of galvanized sheet metal. It is processed in a cold-rolled manner. The result is strong and durable products that are used in the construction process at various sites.
Galvanization allows you to give the metal structures the necessary strength, protecting them from corrosion. As a result, the durability of drywall profiles is greatly increased.
Two groups of profiles are available. The first category includes load-bearing (rack-mount) structures. All profiles that will be mounted horizontally are called start or guides. They have a specific marking. If the rack profile is used to create ceilings, it has a CD index. For partitions, structural elements of this group with the mark CW are used.
What to consider when choosing?
Choosing the dimensions of the starting profile, you need to consider a number of points. On sale are structural elements with different dimensions. They are always indicated in millimeters. When choosing, it is important to consider the size of the drywall sheets. Most often they have a thickness of 12.5 to 95 mm. For wall decoration, sheets of 12.5 mm are most often purchased. The thicker the drywall, the larger the size of the starting profile should be used when creating the structure.
The complexity and overall weight of the structure are also taken into account. The higher these indicators, the more powerful the profile should be. This is necessary in order to create a tough, durable frame. Additional jumpers are also added. They are needed for sustainability.
When choosing a profile, the degree of load on the frame must be calculated. If you intend to create complex structures, shaped elements on which heavy objects will be installed during the operation of walls or ceilings, you need to purchase a large profile.
Feature List
To understand what profiles are, you need to consider their technical characteristics. They may be as follows:
- product depth - 4 cm;
- width - 5-10 cm;
- guide profile section - 28x27 mm;
- weight - 600-840 g;
- form - a section in the shape of the letter "P";
- length - 2.75-4.5 m.
If there is a corrugated coating on the surface of the profile, this further enhances the rigidity of the frame. Holes can be made in the structural elements. This greatly facilitates the assembly process.
Destination
Starting profile for drywall performs the function of guide elements of the frame. They are guided by them, creating additional or main products from drywall. You can mount the starter profile to the ceiling or floor, as well as to the walls. Guides are also installed around the perimeter of the entire working surface.
The scope of the presented products is as follows:
- alignment of walls with drywall;
- creation of a false ceiling;
- installation of arched structures, partitions, other similar elements.
The rack profile can be used as additional stiffeners. This is extremely necessary when mounting thin sheets of drywall up to 18 mm thick. For thin materials, additional clips are provided in the frame itself. They are designed to increase the rigidity of the structure.
Not a single drywall object can do without a rack profile. It is used for all varieties of profile systems. The start profile can perform the function of both the main and auxiliary elements.
Varieties
There are two main varieties of the start profile for drywall. They may have different markings. The first of the starting profiles is used to create ceiling structures. It may be called CD or PP. This is the most popular type of guides.
If you correctly select the dimensions of the profiles of this group, you can rationally plan the space in the room. In this case, when using structural elements such as PP (CD), a minimum amount of waste remains.
For the installation of piers, the CW or PS profile is used. It is worth noting that the quality of the product can be determined by notching. It is needed to facilitate the laying of communications inside the frame. Responsible manufacturers create similar notches in the start profile. Some products have an additional stiffener that looks like a bent edge.
Mounting
Creating a frame from a profile for drywall, you need to properly attach each element of the system. To do this, create a drawing. It indicates all the elements of the future design. This avoids errors.
During the creation of the drawing, the space under the working surface is determined. According to the created scheme, you need to make markup on the basis. In this case, you need to use the construction level. Only the exact installation of each element allows you to get a frame of sufficient rigidity, and the finish of the walls or ceiling will be even.
A profile is attached along the created lines. It is mounted to the walls, ceiling with dowels or anchor bolts (if the weight of the system is significant). Holes create a perforator. If the profile does not have holes for fastening, you need to attach a metal bar to the surface. In appropriate places, serifs are made using a hammer drill. Then the profile is removed. Holes are drilled at predetermined locations. They install dowels or anchors, with which the profile is fixed to the base.
Having considered how to choose and install a start profile for drywall, you can build the required high-quality ceiling or wall structure.
