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 designs of various complexity. From drywall, you can mount them on the wall or ceiling. The frame element, chosen correctly, allows you to get a solid structure as a result. What is the starting profile for drywall, what are its features, will be discussed further.
Definition
The profile on the wall for drywall is made using a special technology. Structural elements of this type are made from galvanized sheet metal. It is cold rolled. The result is strong and durable products that are used in the construction process at various sites.
Galvanization allows you to give 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 produced. The first category includes load-bearing (rack-mount) structures. All profiles that will be mounted horizontally are called start or guides. They have certain markings. If the rack profile is used to create ceilings, it has the CD index. For partitions, structural elements of this group marked CW are used.
What to consider when choosing?
When choosing the size of the starting profile, you need to consider a number of points. Structural elements with different dimensions are on sale. They are always indicated in millimeters. When choosing, it is important to consider the size of 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 starting profile should be used when creating the structure.
Also take into account the complexity and total weight of the structure. The larger these indicators, the more powerful the profile should be. This is necessary in order to create a rigid, durable frame. Also add additional jumpers. They are needed for sustainability.
When choosing a profile, be sure to calculate the degree of load on the frame. If it is supposed to create complex structures, curly elements on which heavy objects will be installed in the processoperation of walls or ceiling, you need to purchase a large profile.
List of features
To understand what profiles are, you need to consider their technical characteristics. They can be as follows:
- product depth - 4 cm;
- width - 5-10 cm;
- section of the guide profile - 28x27 mm;
- weight - 600-840g;
- shape - 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 structural elements. This greatly simplifies the assembly process.
Purpose
The starting profile for drywall serves as the guide elements of the frame. They are guided by them, creating additional or basic drywall products. You can fix the starting profile to the ceiling or floor, as well as to the walls. Guides are also installed around the perimeter of the entire work surface.
The scope of the presented products is as follows:
- leveling walls with drywall;
- creating a false ceiling;
- installation of arched structures, partitions, other similar elements.
Rack profile can be used as additional stiffeners. This is extremely necessary when installing thin sheets of drywall up to 18 mm thick. For thin materials, additional clamps are provided in the frame itself. They are designed to improve rigidity.designs.
No drywall object can do without a rack profile. It is used for all types of profile systems. The start profile can serve as both a main and an auxiliary element.
Varieties
There are two main types of drywall start profile. They may be labeled differently. The first of the starting profiles is used when creating ceiling structures. It may be called CD or PP. This is the most requested type of guide.
If you correctly select the dimensions of the profiles of this group, you can rationally plan the space in the room. At the same time, when using structural elements of the PP (CD) type, a minimum amount of waste remains.
CW or PS profile is used for the installation of piers. It should be noted that the quality of the product can be determined by the notch. It is needed to facilitate the laying of communications inside the frame. Responsible manufacturers create similar notches in the starting profile. Some products have an additional stiffening rib that looks like a bent edge.
Installation
When creating a frame from a drywall profile, you need to properly fix each element of the system. To do this, you need to create a drawing. It indicates all the elements of the future design. This avoids mistakes.
During the creation of the drawing, the space under the work surface is determined. According to the createdthe scheme needs to be marked on the basis. In this case, you need to use the building 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 turn out to 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 are created with a perforator. If there are no holes for fastening in the profile, you need to attach a metal bar to the surface. In appropriate places, serifs are made with a perforator. The profile is then removed. Holes are drilled at predetermined locations. Dowels or anchors are installed in them, with the help of which the profile is fixed to the base.
By considering how to select and install a drywall start profile, you can build the desired high quality ceiling or wall structure.
