The Dibaier Series boasts an unparalleled profiling design, setting a new standard in aesthetics, making these panels the most visually appealing wall solutions on the market today.
Product Parameters
1. Surface Composition: Aluminum-Zinc (Magnesium) Steel Plate
This robust aluminum-zinc steel plate boasts an intricate aluminum-zinc alloy structure. The composition includes 55% aluminum, 43.5% zinc, and 1.5% silicon and magnesium, fused at a high temperature of 600ºC. The entire structure is fortified with aluminum-iron-silicon-zinc, forming a highly durable quaternary crystal alloy.
★ The 0.25mm metal substrate becomes a sleek 0.27mm-0.28mm after the baking paint process. Pre-forming, the aluminum-zinc steel plate bears a weight of 2.0 kg/sqm, ensuring both strength and lightweight versatility.
2. Structural Characteristics:
The polyurethane material showcases a stable porosity structure, predominantly closed-cell (closed-cell ratio ≥90%). This configuration not only delivers superior thermal insulation but also offers remarkable frost resistance and effective sound absorption.
3.Specifications of Metal Carved Panels:
With a thickness of 14/16/20mm, these panels offer a panel width of 415mm, translating to an effective width of approximately 383mm (actual effective width ranges from 360-380mm,The narrowest Great Wall panel measures about 360mm, while the widest flat panel reaches approximately 390mm in width. Seamlessly designed for adaptable length specifications, these panels can be tailored from 2 to 6 meters, facilitating smooth transportation and installation.
Product Structure
Our cutting-edge product is meticulously engineered, consisting of an innovative tri-layer composition:
(1) The surface material boasts a color-coated aluminum-zinc-magnesium steel plate. Enhanced with advanced nano-antifouling technology, it possesses a remarkable self-repairing function that ensures longevity and pristine appearance,
(2) The core of the panel is a robust high-density polyurethane foam insulation layer. This middle layer is not only excellent for maintaining temperature but is also fortified with a specialized fireproof treatment for unparalleled protection,
(3) The bottom material features a durable aluminum foil anti-corrosion layer, designed to effectively prevent degradation and enhance the overall resilience of the panel.
