Horizontal/Vertical Outdoor Heavy Bamboo Wall Decoration Panel Suppliers

How do horizontal and vertical outdoor heavy bamboo wall panels differ in installation and joint treatment?

1. Core differences in installation process: mechanical logic and construction process

The installation process of the Horizontal Outdoor Heavy Bamboo Wall Decoration Panel is characterized by “horizontal support + quick splicing”. The keel layout uses horizontal aluminum alloy or galvanized steel keels, with a spacing of usually 400-600mm, perpendicular to the gravity direction of the wall panel, and mainly bears wind loads in the horizontal direction. For example, in the lateral wall panel installation scheme of Ningguo Kuntai Bamboo and Wood Co., Ltd., the keel is fixed to the base of the building by expansion bolts, and a single keel can withstand uniform loads of ≥50kg/m. Plate fixation is preferred to use snap-on or hidden screws to install: the snap-on process achieves rapid splicing through the wall panel edge design with a wall panel edge accuracy of ±0.1mm, without drilling, and the installation efficiency can reach 15-20㎡/person/day; the hidden screw drills into the keel from the edge of the wall panel at 45° obliquely, and there is no exposed nail head on the surface, which is suitable for projects with high aesthetics. This installation process is suitable for horizontally extended spaces such as low-rise buildings and long corridors. For example, the exterior wall of an open-air restaurant in a coastal resort is horizontally installed, and 800㎡ wall panel paving is completed within 72 hours, which shortens the construction period by 50% compared with traditional technology.

The installation process of Vertical Outdoor Heavy Bamboo Wall Decoration Panel focuses more on "vertical load bearing + anti-deformation design". The keel layout uses vertical keels with a spacing of ≤300mm and needs to be reliably connected to the main structure of the building to bear the self-weight of the wall panel. In the longitudinal wall panel installation standards of Ningguo Kuntai Bamboo and Wood Co., Ltd., the keel verticality error is ≤2mm/m to ensure the consistency of vertical lines. The plate fixation is mostly installed using bright nails or hanging parts: the bright nail process requires the use of stainless steel self-tapping screws (spacing 200-250mm) to be fixed vertically from the surface of the wall panel, and the screw head must be sunk into the board surface 1-2mm and filled with wood wax; the hanging type is hung on the keel through L-shaped metal hangings, which is suitable for high-rise buildings. The load bearing capacity of a single wall panel is ≥80kg. Since the longitudinal dry shrinkage rate of bamboo (0.15%) is higher than that of horizontal direction, 5-8mm expansion joints must be reserved during installation, and rubber gaskets must be installed between the keel and the wall panel to alleviate stress deformation caused by temperature difference.

2. Seam treatment technology: waterproof, beauty and durability balance

Horizontal Outdoor Heavy Bamboo Wall Decoration Panel's seam treatment centers on "concealment and drainage efficiency". The seams are mainly composed of flat seams and staggered seams: flat seams are directly spliced ​​on the edges of the wall panels, with a gap width of 3-5mm, and are filled with silicone weather-resistant glue, which is suitable for modern minimalist styles. The case of horizontal wall panel flat seams from Ningguo Kuntai Bamboo and Wood Co., Ltd. shows that the color matching degree of glue seams and bamboo patterns is ΔE≤1.0, and the visual integrity is strong; the staggered seams are staggered by the horizontal seams of adjacent wall panels, forming a "work" arrangement similar to brick walls, which can disperse stress and enhance wind resistance, and are often used in coastal projects. In terms of waterproof design, an aluminum alloy waterproof cover is added to the outside of the horizontal joint, with a slope of ≥5%, guiding rainwater downstream. After testing, it can withstand 50mm/h heavy rain erosion and no leakage.

The Vertical Outdoor Heavy Bamboo Wall Decoration Panel's seam treatment focuses more on "crack prevention and self-cleaning". The seams are mainly V-shaped seams and dense seams: V-shaped seams are milled with a 45° bevel at the edge of the wall panel, forming a V-shaped decorative seams of 8-10mm, embedded with elastic sealant, which has both decorative and telescopic functions. For example, the longitudinal wall panel of a new Chinese-style courtyard adopts a V-shaped seams, with dark brown glue seams forming a color contrast with bamboo patterns, strengthening the rhythm of the facade; dense seams are tightly spliced ​​by high-precision cutting with an error of ≤0.05mm, leaving only 1-2mm natural gaps. It is suitable for dry climate areas. Wood oil is required to be regularly injected to prevent the gaps from expanding. In terms of self-cleaning properties optimization, vertical seams are not prone to accumulation of dust due to gravity. After the surface of the longitudinal wall panel of Ningguo Kuntai Bamboo and Wood Co., Ltd. is treated with nanocoating, the dust adhesion is reduced by 60%. Rainwater can be washed and cleaned naturally, and the maintenance cycle is extended to 2 years/time.

3. Comparison of environmental adaptability and maintenance costs

In terms of environmental adaptability, the seams of Horizontal Outdoor Heavy Bamboo Wall Decoration Panel are parallel to the wind direction, and the wind load is evenly distributed, suitable for areas with a typhoon level ≥10; its horizontal keel can buffer the horizontal displacement of the earthquake, and the allowable displacement value is ±5mm. During maintenance, it is necessary to regularly check the aging of the waterproof glue (period 1-2 years), and the plate cutting loss rate is ≤5% (high standard size adaptability). The seams of Vertical Outdoor Heavy Bamboo Wall Decoration Panel are perpendicular to the wind direction, and additional reinforcement of keels (spacing ≤250mm) are required, suitable for wind areas of ≤8; the vertical keels need to be equipped with sliding connection nodes, with an allowable displacement value of ±3mm. During maintenance, debris in the vertical slits (period 0.5-1 year) must be cleaned to prevent plant roots from invasion, and on-site cutting and adaptation are required, with a loss rate of 8%-10%.

4. Choice logic in industry practice

In the scenario of priority construction period, commercial fast-installation projects (such as exhibition halls, temporary buildings) are more suitable for horizontal snap-on installation, with a single-day paving volume of up to 300㎡; in scenarios with high aesthetic requirements, cultural landmarks and high-end residential buildings can choose vertical V-shaped seams or dense seams, and they can be combined with carbonized bamboo to create a delicate texture; in complex climate scenarios, horizontal staggered seams + waterproof covers should be used in windy and rainy areas to strengthen waterproof and wind resistance, while in cold and dry areas, longitudinal dense seams + expansion joints should be used to reduce the risk of temperature difference deformation.

The installation process and joint treatment differences of horizontal and vertical outdoor heavy bamboo wall panels are essentially a comprehensive reflection of architectural mechanics, environmental engineering and aesthetic design. The horizontal process is known for efficiency and stability, while the vertical process is advantageous for vertical lines and cultural expression. In the future, with the popularization of prefabricated buildings, a standardized horizontal and vertical compatible installation system may become the mainstream of the industry, further improving the application breadth and reliability of outdoor heavy bamboo wall panels.
