Crate under the metal roof
Profiled distinguished easily used in such a coating material exposes lath relatively small loads, thus saving on lathing apparatus. In addition, a small angle of inclination does not exclude the use of corrugated board - lathing, even in such circumstances will securely hold the covering in any weather. These roofs are characterized by high durability, can withstand low and high temperatures. Most often they are installed on residential homes, cottages, garages and other small buildings.
There are two types of roofing, corrugated compatible with stacking - one - and gable roofs, the inclination angle which should not exceed 60 degrees. Crate under the decking for these types of roof is made of wooden beams laid at an angle of 90 degrees to the rafters and fastened with nails. Properly designed crate will help distribute the load evenly and create a solid roof.
Crates under the decking is easy and quick to install, do not need special building materials for them - you can rack to fix the most common staples, in addition, the roof structure is easy to carry out wiring or other wired networks. The material for the crates are wooden poles or planks under the crate should be laid insulation and waterproofing. Before you choose a design for the crates, you need to carefully examine the angle of the roof of the future. Dimensions and design step are selected based on the height of the corrugations of the roofing material. If the roof slope does not exceed 15 degrees, it is necessary to use profiled C20. It will require continuous crate, and the material will be laid in two waves.
If the tilt angle exceeds 15 degrees, you need to make a crate so that its step was 350-500 mm. Installation of the supporting structure is not a difficult procedure - to strengthen enough along the eaves carrier board, which should exceed all others in size. For this it is necessary to nail the rafters are perpendicular to the rack, whereupon you can install the carrier boards according to the selected schedule.
