Equipment mounting screws to the roof sheeting

Fixing screws to the roof sheeting comes in a special process, thereby erected a roof can last about 45 years.

Most often, the decision to choose as a roofing material profiled explains the universal characteristics of the product.

modern coating has good durability and high resistance to climatic factors, respectively, made with its use of the roof is obtained reliable and durable.

Besides proflist not require regular painting because the sun does not burn.

What screws used for fixing sheeting?

Construction trapezoidal sheet roofs is performed with the help of metal screws.By the way, these fasteners are used for fastening metal roofing.

It does not matter what material was made crate for corrugated board, as soon as the high-quality screw screws used for wood and metal for the frame structure.

They come with a rubber sealing element, as in the photo.

If during the installation of the roof to use fasteners that are not intended to fix the profiled sheet, fasteners shake loose over time and covered with corrosive coating.

recent troubles can be avoided if timely and properly seal the sealant appeared around the screw holes.

While installing decking on the roof, there is no need to pre-prepare the hole as fixings had the foresight to feature in the production of caps in the form of drills.

This anchorage sites get tightness due to the rubber seal, which is equipped with a screw.Regarding

length of fasteners, it may be different - from 19 mm to 250 mm with a diameter from 4.8 mm to 6.3 mm.

best option for fixing the sheeting to the roof can be considered 4,8h28 mm screw and screw with a length of 35 mm, 50 mm and 60 mm.

Ridge element must be mounted using the screw with 80 mm.In general, the fastening element length should be greater than the total thickness of the sheet and the batten 3 mm.

heads roofing screws must have skirting with a height that would allow are properly held metal screws when screwing in a bit screwdriver.

Features of the calculation of screws for fastening corrugated

calculation of self-tapping screws for fixing sheeting can be done in several schemes, unique and personal.Calculation of

first technique is considered more simplified, since during the calculation figures do not vary.

With minimal wind loads can be sure that the steel sheet will not vibrate.

therefore making calculation of the number of screws used 4 pcs.fasteners per square meter.

If the expected heavy and constant load on the roof structure, carry out the calculation, on the basis of figures 8 pcs.per square meter.

One example is the calculation of the number of self-tapping screws for mounting on the roof with a bevel of 50 square meters.m.

This house stands on an elevated, open to the wind space.

making payment, you must take into account the steady wind loads, resulting in a calculation carried out show that it is necessary to use the maximum number of fasteners.

The output is the following scheme: 50 m 2 x8 plus 5% is equal to 420 pieces of screws.Where, 5% - is a deviation, without which the payment is not made.

Although the calculation of the number of fasteners and will be carried out properly, with the purchase of screws is better to take them a little longer.

Calculation screws on personal technology is much more complex, since the calculation takes into account not only the load on the roof of the future, but especially crates, corrugated board and the appointment of the surface.

For example, when installing a fence is necessary to tighten the screws in the sheet between the waves, on 2-3 levels.

If the expected heavy load, it is recommended to screw the screws 2 pcs.a list for each level between the waves.If

roofing fasteners screwed into the sheet metal lath and roof, it is usually taken at a distance of 500 mm, without the expected load distance can be increased.

In general, each situation is examined individually, but more personal method of calculation used in special cases.

Rules corrugated roof mounting

Once considered the issue which need screws for fastening corrugated roof, is familiar with the peculiarities of fastening of roofing material.

After properly conducted installation becomes a guarantee of the reliability of the design.

First and foremost, you must take into account the future destination of the roof, because the arrangement of the roof with the attic floor, as in the photo, will differ from the installation of the roof of a residential facility with a cold attic.

Perhaps Decking you need to hide the garage or outbuildings.

In any case, the object of the design depends on the destination, the area, the number of layers of the roof, as well as the amount of steel sheet and screws.

This sheet used for mounting on the roof, must have certain parameters.

As a rule, to build a roof, use a universal profile plate "H" in this case, the height and thickness of the corrugations is determined separately for each facility.

How do I calculate how much and what kind of screws you need for mounting trapezoidal sheet, we have considered above.

This will properly use screws with rubber gasket for a simple cloth, and for the installation of valleys - with a tin seal.Mounting

sheet products start from the bottom of the slope of the roof, the sheet must hang from the roof bit, which would protect the wall of the house from precipitation.

Screws screwed exactly perpendicular to the surface of the roof.Steel sheet can be mounted at 3-4 in the block, which makes it possible to speed up the workflow.

Also do not forget that the horse of the roof must be fixed to the top of the sheet wave, while trapezoidal sheet area is mounted to the roof sheathing only between waves.

waterproofing and vapor barrier roof

Correctly charting layers of steam and waterproofing of the roof gives the advantages.

insulating materials arranged between the roofing products and a crate can help to protect the attic space from moisture.

eliminates condensation - such trouble occurs when the difference in temperature inside and outside.

In this case, the condensate is a threat to the roof structure, causing it damage.

Depending on the functional purpose of the object is determined, how many protective layers will be arranged on the roof.

For example, the number of housing units they must be more because in addition to insulation and waterproofing is required fastening vapor barrier.

vapor barrier installed under the insulation in order to protect it from the steam coming from inside the room.

waterproofing layer Installation of decking under perform over the insulation.

used as waterproofing membrane film, the properties of this material make it possible to protect the insulation from moisture.

If not a profiled lay waterproofing material, the condensate in the form of moisture will not discharged from under the roof space, with the result that the service life of profiled sheet halved.

How to calculate step crates under the decking?

mainly for residential properties crate for the future of corrugated roof made of wooden beams.

The distance between the batten bars can be different, it all depends on how many degrees is the angle of the bevel of the roof, and the height of the corrugated sheet.

basic rules and options for securing crates:

• If the angle of the bevel of the roof is more than 150, making crate with a step of 35 to 50 cm;
• If the slope of the bevel is less than 150, the frame under the roofing battens profiled perform vsploshnuyu.When this sheet product should have a wave height of 20 mm.In this case, the steel sheet must be performed fastening lapped to 20 cm;
• If we take the slope of the roof 150 and profiled sheet with a wave height of 35 mm, the distance between the bars should be more than 30 cm. The material itself is laid with an overlap of 20 cm. Profiled sheet Fixing with a wave height of 44 mm is carried on a crate, laidin increments of 50 cm;
• If the angle of the roof slopes is 200, then the size of the overlap should be equal to 10-15 cm with crates of 30-40 cm step;
• small angle, for example 120, may have a different roof structures.The joints of the profiled sheets need to apply silicone sealant to the strength you can fix construction of iron rivets.

Fastening corrugated carried out correctly, but the roof leaks

happens that mount profiled sheet roof was done correctly, but the roof is leaking.This trouble can be caused due to incorrect cutting sheets.

Fit steel sheet under the desired settings recommended by conventional or electric scissors for metal.This oblique notches better cut electric jigsaw.

After cutting edge materials it is necessary to process the waterproof sealing structure that would eliminate the appearance of edge corrosion.

When mounting on corrugated metal girders, doing a hole screws in advance.

Therefore, in order to avoid leaks, without fail, each of them must be treated with sealant.

move on the roof of recommended shoes with soft soles, because the workflow is not always involves finding a roofer only crate.

In addition, you do not accidentally damage the protective layer of steel sheet, they can not put the tools, it is better for this purpose use special boxes.

If, however, the protective sheet film has been damaged, you must first place the damaged grease rust preventative and apply water-resistant paint on top of it.

After 2-3 months after installation of the roof of corrugated board is recommended to re-tightening of fasteners.

This approach would eliminate the loose, which can occur due to sudden changes in temperature air.
