To make orientation easier, FassadenGrün bar systems are categorised into 3 ‘series’. The second, already quite strong series with rods of 8 mm diameter is suitable for creating large-scale structures that would otherwise only be possible by lining up several finished wall grilles.
The 8 mm rod system can be used to create customised, precisely fitting arrangements and even spatial plug-in grilles. Medium to large ‘meshes’ can be created. Of course, small meshes with edge lengths of less than 0.5 m are also possible. The 8 mm series is ideal for vines and many other woody climbing plants.
8 mm rods are available in lengths from 30 to 315 cm. You can use bar clamps to build grids, either in advance on a base (‘Variant 01’) or directly on the wall (‘Variant 02’). You also need grid holders, all types up to 8 mm slot width are suitable. Bar connectors are available for very large grilles.
The 8 mm series is ideal for vines, honeysuckle, climbing trumpets and other woody climbing plants. For woody climbing plants such as akebia and pipevine, the 8 mm series is suitable if a wall clearance of 7 - 10 cm is guaranteed (suitable trellis holders) due to the expected stem diameters.
On the other hand, the 10 mm series should be selected for ‘strong climbers’ such as blue vine, knotweed and tree strangler.
In the overview below, you can see which of our 54 ‘basic rope shapes’ are also available as pole systems with 8 mm rods. You can also check whether a basic shape you have selected harmonises with the growth of certain climbing plants or whether the respective basic shape is recommended there.
Medium to very large ‘meshes’ can be formed:
- approx. 40 cm x 40 cm (medium)
- approx. 50 cm x 50 cm (large)
- approx. 60 cm x 60 cm to approx. 75 cm x 75 cm (very large)
In addition to square meshes, rectangular meshes are of course also possible. However, the mesh size should always be at least 30 cm x 30 cm or 25 cm x 40 cm, otherwise the 6 mm series would be more effective.
In theory, rods and modular trellises can come loose from their fixings and fall down. Particularly at greater heights, this can result in damage to property or personal injury, for which the system provider or installation company may be liable. FassadenGrün hereby assures that only faultless components are supplied, thus preventing faulty clamping and a safety risk. Please observe the information on the product sheets for the lattice supports, e.g. regarding the recommended installation height and clamping force.
Modular grilles can be completely assembled before wall mounting, e.g. on a table or on the floor. It is advisable to place cardboard or similar underneath to prevent scratches on the stainless steel. On the wall, individual bar clamps are then loosened again to insert the grilles exactly into the grooves of the grille holders mounted there.
A modular grille can also be assembled on the wall. To do this, the grid holders are first placed at the planned locations and individual rods are mounted in them, usually vertical rods. The bar clamps are then threaded onto the horizontal bars, after which the horizontal bars are mounted on the vertical bars or behind them.
To make the grid structure more compact, additional vertical rods can be fitted last. These are then only attached to the horizontal bars with bar clamps, so no additional grid holders are required.
The main focus here is on basic shapes such as number 8030, see below. The number of grid axes is important for reasons of economy. This is the key to minimising the number of fixing points and reducing costs! The key is to minimise the number of fixing points and reduce costs. If possible, the distance from grille bracket to grille bracket should not exceed approx. 1.50 m, both horizontally and vertically. Larger distances and thus possibly also greater economy are possible with the 10 mm series. The following recommendations apply to 8 mm grilles with (approximately) square meshes:
You can also build medium-sized to large plug-in grids with 8 mm rods, namely flat grids with 2 x 1.97 m rods and spatial grids with 3 - 4 x 1.97 m rods. The 1.97 m long rods are used for insertion, e.g. into a very large flower pot or directly into the ground. Further vertical rods, e.g. 1 m long, then complete such a grid above the surface of the ground.
(For medium-sized meshes, see above). The number of vertical axes should be a ‘multiple of four’ plus ‘one’, so the calculated number of axes would be 5, 9, 13, 17, 21 etc.. Grid holders (grey circles - see diagram) are then placed on the first and on each additional fourth axis. The number of horizontal axes should be a ‘multiple of four’ plus ‘two’, so the calculated number of axes would be 6, 10, 14, 18, 22 etc.. The grid holders (grey circles - see diagram) are placed between the lowest and the second and four axes further up.
(Large meshes see above). The number of vertical axes should be a ‘multiple of three’ plus ‘one’, so the calculated number of axes would be 4, 7, 10, 13, 16 etc.. Grid holders (grey circles - see diagram) are then placed on the first and on every further third axis. The number of horizontal axes should be a ‘multiple of three’ plus ‘two’, so the calculated number of axes would be 5, 8, 11, 14, 17 etc.. The grid holders (grey circles - see diagram) are placed between the lowest and the second and three axes further up.
(For very large meshes, see above). The number of vertical axes should be a ‘multiple of two’ plus ‘one’, so the calculated number of axes would be 3, 5, 7, 9, 11 etc.. Grid holders (grey circles - see diagram) are then placed on the first and every other axis. The number of horizontal axes should be a ‘multiple of three’ plus ‘two’, so the calculated number of axes would be 4, 6, 8, 10, 12 etc.. The grid holders (grey circles - see diagram) are placed between the lowest and the second and two axes further up.
(Red circles, see diagrams). Due to the weight of the bars and the large distances from bracket to bracket, the horizontal bars may deflect slightly. However, this is more of an aesthetic problem than a functional one. As a preventive measure, additional wall brackets can be inserted on the bottom horizontal row so that more vertical bar axes have a wall bracket at the bottom. The red circles in the sketches above represent such additional grid holders.
You can combine as many horizontal and vertical bars as you like. However, only angles of 90 degrees or rhomboid shapes of 45 / 135 degrees are possible, and a maximum of 2 rods may cross at each crossing point. For stability, EVERY crossing point should be fitted with a bar clamp. The overhang of the bars should be small to prevent injuries. We recommend an overhang of approx. 1.5 cm outside the imaginary axis. This means that with a 50 cm wide grille as shown in the photo, the imaginary axes of the two vertical edge bars are 47 cm (50 cm - 2 x 1.5 cm) apart. The grille supports are therefore 47 cm apart horizontally.
It must be determined whether the vertical bars or the horizontal bars should be ‘in front’, i.e. further away from the wall. The visible side for the rod clamps must also be specified: Tamper-proof ‘knob’ look or a more technical look with visible grub screw. Please refer to our tips on the quantity and arrangement of grid holders.
