Any product Drywall necessarily has a "backbone" - a frame made of durable parts.It profiles and guides of different shapes connected by various fasteners.The quality may be different.Alas - sometimes bought a marriage can only be known at the installation, and then using the final design.This is a problem of developers who do not have experience.By selecting the desired types of profiles for gypsum board, they do not know how to find quality products.But it can not be wrong, so consider what are the types of profiles, accessories and fasteners for gypsum board, consider the criteria for the selection of these elements.

What are plasterboard profiles: types and sizes

profile is used for the manufacture

of cold-rolled sheet metal, galvanized processed.Products are obtained strong, practical and reliable.After the galvanized surface corrosion is not dangerous, so this profile destined to a very long life.

frame of metal used for drywall, the construction is simple.It includes horizontal and vertical detail.The latter are called carriers, or blade, the elements.They are arranged perpendicular to the rails, or starting elements.Select the appropriate profile for the walls of plasterboard is not so difficult.To begin with we list all of their views.

Rack type (CD or PP profile)

Rack profiles (still referred to as the ceiling) - one of the most popular.They are, according to the marking Knauf, denoted by the letters CD.Similar products brand gypsum plasterboard called PP profiles.Thanks to their optimized dimensions rationally and sparingly used space.When the smokers waste virtually any size remains.

CD rack profile
this profile is used for the manufacture of the frame in the wall and ceilings.

Profile Size:

  • length - from 2.5 to 4 m;
  • Width - 60 cm;
  • shelves height - 2.7-2.8 cm.

guide profile for plating (UD or PPN)

UD (or PIP) profiles - guide elements of the framework.Oblitsovyvaya plasterboard wall or ceiling pitching, need around the perimeter of the plane to mount such details.Since mounting profile data auger extends right through them, it is desirable that they have been perforated.After the holes borax will enter a lot easier.

The guide profile
used as a guide into which the rack profiles.

Dimensions guides for plasterboard:

  • Length - 3 m;
  • thickness - 0.55 mm;
  • width - 2.7 cm;
  • height - 2.8 cm.

profiles to create partitions - UW or CD

guiding profiles to create partitions are marked UW or Mon.To be able to make any septum thickness, which is necessary, these parts are manufactured with a large line sizes, in particular widths.

UW Profile
used in the frame as a guide when creating partitions.

Profile Size:

  • length - from 2 to 4 m;
  • height shelves - from 3.7 to 4 cm;
  • width - 4.2, 5, 6.6, 7.5, 10, 12.5, 15 cm.

Profiles for partition - CW and PS

Rack profiles for partitions marked letters CW and PS).In width, they are matched to the starting element.Quality products always have a special notch to facilitate the construction of communications.Profile of gypsum plasterboard item PS has an additional stiffening rib, which creates a folded edge.

CW profile
used to create a frame for mounting walls.

Dimensions Profile for plasterboard:

  • length - from 3 to 4 m (special lengths made to order);
  • shelves height - 5 cm at the Knauf and 4 cm in gypsum plasterboard;
  • width - according to the profile of UW or Mon.

Arched profiles

Special curved profiles can be both convex and concave.They are used when the design to do a complex shape with curves and curved planes (for example, the arch).However, if necessary, our craftsmen learned how to do rackmount profiles.

What additional elements necessary framework

There are many ancillary components for plasterboard - they number more than a dozen.But some of them did that in the catalog can be seen as they have special meaning.And we will look at the items that are used most often - enough of them to any master.

Duplex connector LED Profile

duplex connector for CD profile is used to secure the profiles at different levels.The direction perpendicular to each other.Since this item is sold in the form of a scan before the operation Let us give it the shape of the letter "P", this arching.For installation require special screws (2 pieces - one on each end).

Crab to connect CD profile at the same level

siblings connectors for CD profile called "crabs."They are intended for fastening of parts within one level.As in the previous case, they are placed crosswise, perpendicular to each other.If the load per square meter is not more than 20 kg, the screws are not required - just snaps into profiles.Otherwise, the screw need 2 - one and the other side.

Direct suspension

Straight hanger for CD profile is used for the installation of suspended ceilings.This item is fixed directly to the ceiling surface.Before connecting to a core element of the hanger bent with the letter "P".Then screw on the edges, 2 self-tapping screws.The length of this product (standard) is 12.5 cm. Available options are also other - from 7.5 to 30 cm. A load suspension stand which is ready to be 40 kg.

Anchor hanger

Anchor suspension, also called suspension with traction also serves to connect the ceiling and CD profile.It is needed when direct suspension is not long enough.Suspension itself is inserted into a profile and its thrust must be threaded through special holes provided in the spring.Link 25 may be a length of 50 cm and 100 cm. Maximum load - 25 kg.

Extension CD Profile

extension for CD profile (otherwise, the longitudinal connector) is able to make the profiled element is longer.This piece is inserted into it at the end face, with projections similar to the horn should be directed upward.As usual, the edges of the two self-tapping screws are screwed for added rigidity.


corner connector for CD profile may replace a member of the "crab" when installing suspended ceilings, with one level.

Fastening for plasterboard systems

Screws TN 25


to securely fasten drywall to metal surfaces, use screws with the common thread type TN25 (25 mm).If the sheathing in several layers, taking screws 35 - 40 mm long.To attach to the GCR crate of wood, using screws with wide pitch thread length of 35 mm.

Screws LB 9, 11, 16, and LN 9, 11, 16


Attach a straight suspension, extending and linking different types of profiles for gypsum board should be boring screws type LB 9, 11, 16. Suit and piercing screwsLN 9, 11, 16. The numerals indicate the length of the screw in millimeters.The smallest piercing screw LB 9 has a length of 9 mm.All fasteners have a small disadvantage - they are difficult to spin.A hat heavily favored and prevents from fitting drywall.

screws to press the puck


More practical use universal screws to press the puck, which can work with any surfaces.They do and piercing, and boring type.Length ranging from 9 to 100 mm and sometimes more.The most popular sizes - 16 and 14 mm, which can be used almost anywhere.

Self nylon dowels


for wall mounting rail profiles for drywall or UD UW type is best to use plastic dowels.

Anchor wedge-


direct or anchor suspensions conveniently secured to the ceiling by means of special fasteners, wedge anchor.It takes no corrosion, it is not subject to fissuring and therefore is impressively long.In the manufacture of the ceiling is not worth saving.Fasteners must necessarily be metallic and durable.In addition, you can use the ceiling anchor.

dowel - nail


If we attach frame (suspensions and guide profiles) to the bearing elements of concrete, bricks or blocks, then take a special dowels.Suitable plastic fasteners, mushroom-head with a diameter of 6 mm and a length of 40 - 60 mm.They can be driven directly with a hammer.Before the work you need to stock various types of fasteners, to be able to connect any of the items, such as hollow.When used with suspensions anchor rods take TDN or equivalent.

Tips for choosing a quality fasteners and profiles

Before buying, check that the profile elements are equal, have the appropriate size and intact zinc coating.Curious about how to select a profile for drywall, remember that the thickness is less than 0.55 mm is not permitted.Do not forget that not everything that is sold in the market and in-store compliance.

There are the following types of marriage:

# 1. Metal has insufficient thickness - it is a big disadvantage.Back then, when the screws are scrolled as quickly thread breaks.Check the thickness of the easiest with a tool (caliper).If it is not at hand, then as an option, you can compare the profiles from different manufacturers.

# 2. rust definitely should alert you.Since the corrosion process has begun, it will continue to go on.And even if a pack of profiles glitters abundant lubrication, it is a good sign.Most likely, the seller so he tried to disguise the fact that the coating is poor quality.

# 3. Incorrect rolling visible almost immediately - enough to pull out a single item from the pack.If you look at it along, it can be seen that the profile of the whole twisted, and the shape of it, to put it mildly, is far from ideal.Definitely have to give up the purchase, and the torment exhibit profiles.By the way, when stored properly, too, there are such problems - parts bend and deform.

# 4.Inaccurate size - one of the most harmful forms of marriage.Especially if you start the profile height of the shelf is less than necessary.And work is inconvenient, and the frame will turn so-so.For smooth parts such as CW height shelves must be exactly 5 cm, and for corrugated SS Gyproc-Ultra may be a little less important.And even if the size of the profile for drywall slightly less than necessary (2.48 m instead of 2.5 m, as some manufacturers), we should not allow this.

# 5.If incision is made too rare or too weak, it will be hard to screw screws.They dance on the surface for a long time, refusing to go to the right place.And if at the edges of shelves CD profile is too high, the screws too hard to screw LN.Their sting is always on inclined planes.

# 6. When buying fasteners check the edge - it can even try a couple of screws screwed into the metal.Visually check whether there is a pack of fasteners, whose tip is broken or there are the remains of the metal.Heads also check - they must have a clear slots, slotted well.Otherwise, the bit will not hold on screws.Marriage slots can be cast in poor quality or a metal, its zabivshem.No trace of rust should not be.

# 7. profile with burrs never take - all hands will be cut up.A very dangerous and urgent thing.

# 8.At check dowels Plastic plugs.If there are a lot of sagging, then push the plug into the hole are difficult.Stopper loosely held in the hole and poorly disclosed.
