Pine Knot Grain Flat Panels with Double Straight Grooves are pastoral-style insulated integrated exterior wall siding with cost-effective performance. The flat panel surface is designed with two full-length neat straight grooves. The lifelike pine knot texture printed on the panel restores primitive rustic wood aesthetic at a much lower cost than real solid wood.
This panel adopts a 3-layer composite structure: weather-resistant aluzinc steel sheet on surface, high-density PU foam core in the middle and moisture-proof aluminum foil backing at bottom. It integrates thermal insulation, waterproofing, Class B fire retardancy, noise reduction and exterior decoration functions, serving as a perfect replacement for solid wood, exterior tiles, real stone paint and ordinary color steel plates.
The reinforced double straight groove structure enhances bending strength and wind resistance, resisting warpage and deformation under extreme outdoor climate. Interlocking buckle joints realize seamless splicing to stop rain infiltration, wall dampness and mildew growth efficiently. The weather-resistant coating resists yellowing, fading and cracking with self-cleaning property, offering an outdoor service life up to 30 years.
Lightweight design reduces wall load, and mortar-free dry installation shortens construction cycle and labor cost significantly. Custom sizes, grain shades and colors are available to match different architectural designs.
It is widely applied to farm inns, rural villas, scenic buildings, factories, container houses and old building renovation projects. Complete export documents are provided for bulk shipment to Southeast and Central Asian countries like Indonesia and Kazakhstan, with flexible trade terms including EXW, FOB and FCA.
