Rules for overlapping sheets

At different angles of inclination of the roof, sheets overlap to different quantities:

• The largest is 20 cm, if the angle of inclination is less than 15 degrees.
• At an angle of 30 degrees, there is enough admixture of 10-15 cm.
• With a small coal of inclination of the roof, less than 10 degrees, sheets of sheets are additionally sealed.

Roof lamp

Sheets of coating are attached to the crate (wooden slats), which are fixed to the structural elements of the roof. The distance between the bars (shap shabby) depends on the angle of inclination of the roof and the brand of professional flooring. If the roof inclination angle is more than 15 degrees, the shaft step from 35 to 50 cm. If the slope is less than 15 degrees, the brand C35 brand is used, the step is from 30 cm, and for the C44 corrugated floor - from 50 cm. For an angle of less than 20 degrees, a doomlet is made Step 33 to 40 cm. For roofing, professional flooring is used with a corrugation height of at least 50 mm.

Fasteners

The flooring is attached to the crate of roofing self-drawing, with multifaceted heads under electric devices for wrapping. Do not use nails for fastening the coating, they may not withstand strong busting winds. Self-tapping screws are covered with a polymer of the color of the cornet, so as not to stand out on the roof. Short fasteners are fixed sheets of professional flooring, long - rods of the roof. From the opposite side, the bolt is made in the form of a drill, with which the hole is performed on the sheet. There are fasteners with diameters 4.8; 5.5 or 6.3 mm, with a length of 19 to 250 mm. Self-tapping screws are used in conjunction with volcanic rubber gaskets and aluminum washers.

General recommendations for the choice of self-seases look like this:

• Buy self-tapping screws together with a professional flooring. This will reduce the danger to buy a fake.

Place the sheets so that they hide at least 3-5 cm to protect the wall of the building. Profile settled with the allen on neighboring elements.

Secure the sheets by self-drawing, adhering to the following advice:

• Self-tapping screws Out of a low-unique drill, with a delay control device. If you tighten the fastener manually, then calculate the power not to damage the insulation.
• Tightening fasteners Control over the sealing gasket, it should perform at the edges of the washers by 1-2 mm.
• Fasteners screw at right angles to the surface.
• Self-tapping screws are applied at the place of the wave deflection. 6-8 sams are usually taken to the sheet - they are screwed along the edges of the sheet, in the places of the adolescence and in the middle.
• The next row is located above the bottom with the allen vertical 10 cm.
• After mounting the skates from above, set the skates and secure long screws. Three months later pull the screws, because Fasteners on a tree can weaken.
• It is forbidden to connect the neighboring sheets of hardwood with welding and cut off the excess gas cutter.
