It is noticed that the graceful forms of additional elements give the facade of metal siding a complete view. Correctly selected and installed elements are a powerful technique for conducting facing works with modern materials. The main thing is to choose the right one, to learn how to calculate the length and mount the mounts.

Makeup for the facade
To give the facade a new look and "zaderkorit" podnadoevshy and shabby look of the old helps metal siding. An obligatory element of the facade decoration can be called additional elements for metal siding.
The main purpose of the additional elements is the concealment of defects in the facade and junction joints without additional expensive repairs or upgrades. What elements exactly create the facade of metal siding neat appearance?
Let's start with the fact that the facade, lined with metal siding, is assembled from standardized elements, the sizes and area of which are calculated at the design stage. This number also includes metal additional elements intended for finishing door and window openings with minor modifications in the place of installation.
But the individual construction of private houses and the configuration of each house require solving decorative tasks in its own way. How should I select the elements?
Helpful Tips
When selecting additional elements, it is necessary to focus on the color of the main elements of the facade, lined with metal siding. In this case, the decorative component of the external facade will be complete.
What are the additional elements for the facade
For the facade of the building, faced with vinyl or metal siding, the following additional elements exist:
• the initial and final bar is simple and complex (U-shaped)
• inner and outer complex angle strips
• inner and outer corner strips of simple
• H-bar and P-lath
• Elements of contiguity
• Docking straps.
All these elements of the facade have a characteristic configuration.
material and dimensions
Elements are made of galvanized steel with subsequent coating of polymer. All the additional elements, as well as the strips, are made of steel with a thickness of 0.5 to 1.0 mm. This means that the chisel, as well as the basic elements of metal siding, are durable, strong and resistant to any negative atmospheric influences.
The dimensions of the additional elements correspond to the dimensions of the main elements, the length of which reaches 2.5 - 4.0 m.
Modern sheet-bending equipment, on which the additional equipment is manufactured, allows:
• Cut the metal to a width of 1250 mm and a thickness of 1.0 mm with a specified accuracy of 0.1 mm
• bend profiles of the required configuration according to the customer's projects from metal with a thickness of 1.0 mm.
In addition to the manufacture of additional elements for the facade or roof, the possibility of folding allows the manufacture of boxed facade elements (cassettes).
configuration
Structurally, the slats and profiles have special curved shelves to accommodate fasteners. The shelves are located along the entire length of the slats. The width of the shelves can reach 10-20 mm, which allows you to pick up the fasteners and install it in the center of the shelf.
The configuration of the bars and profiles has a complex curved appearance. A simple configuration (in the form of L) only for simple starting bars. The most "heaped" configuration in complex corner slats. This is due to the two-sided loading on the corner elements of the metal siding and the weight of the structure.
Naturally, such a metal structure must be securely fixed. For this use traditional crate and special fasteners.
Fastening or on what "hang" additional elements
In the additional elements, unlike the main metal securing fasteners, there are no special perforations that allow to correct the position during installation. Therefore, for each node of metal scoring requires its own mounting option.
The nodes of the facade, where they use additional elements
external and internal angles
For the cladding of external and internal angles, when mounting metal scoring, corner elements are used that differ in the complexity of the configuration. During installation, fastening of panels and additional elements is made in each corner.
An optional option for installation of additional elements are: slats for window slopes, ground and parapet or transition bars.
connecting rail
The connecting rail is installed in the joints. The type of installation of the rail depends on the number of floors of the facade and has several design versions.
docking strap
The docking strap is an overhead element. It is installed over the mounted metal siding, closing the joints and gaps formed during installation.
framing and filing of the frame
The simplest is the direct framing and filing of the frame, which is carried out using an internal corner with a fixed painted self-tapping.
The most technologically challenging is the framing of window openings, where in the process of facing will be involved: the angle of the window slope, aquilon and window water drainage.
Calculation of additional elements for skinning
The calculation of the main fastening elements for the lining is made according to the size of the area for the cladding.
Calculation of additional elements is made along the length of the perimeter. For example, the length of the starting and finishing bars is calculated along the perimeter of the upper and lower parts.
The outer and inner corners are calculated from the height of the building, taking into account the length of one bar. For each angle, this value is determined separately, and to determine the total amount, the obtained data is added together. The length of the connecting bars is determined in a similar way. The length of the slats is calculated according to the length of the perimeter of the window, if there are several windows, the resulting value is summed.
The joining of additional elements to the main elements of the metal siding is carried out using standard fasteners.
Elements of fasteners
For fastening of additional elements use the following fasteners:
• galvanized self-tapping screws with gasket 4,8x35 mm
• simple galvanized self-tapping screws 4,2х16 mm
• dowel nails 10x100 mm
• crutches and rivets
calculation of fasteners
For the basic fastening metal siding with a foam-type insulation, we use dish dowels, which are arranged in an amount of 5 pieces per sheet with a depth of 50 mm.
For fixing and fixing the panels on the lath used T-shaped and L-shaped profiles with a pitch of 30-60 cm.
The main function of the additional elements is to strengthen the overall fastening of the skin, so the minimum fixing step is 20 cm. Thus, to fix the three-meter bar, it will take about 15 self-tapping screws with a size of 4.2 mm.
How to implement the window frame with metal siding and additional elements, is shown here.
In exceptional cases, resort to the use of non-standard elements of the facade cladding (ebb and corners), which are manufactured according to individual orders.
