Sandwich Metal Siding Panel
the Sandwich Metal Siding Panel adopts high-density polyurethane foam with a density of ≥ 40kg/m ³ as the sandwich material, and the thermal conductivity is as low as 0.022 W/(m · K), which increases the thermal insulation efficiency by about 45% compared with the traditional rock wool board. Whether in hot summer or cold winter, it can effectively reduce indoor temperature fluctuations and lower air conditioning energy consumption by more than 30%.

01
High strength structural characteristics
Its panels are made of aluminum zinc coated steel plates or stainless steel materials, with a tensile strength of over 280MPa and a unit area weight of only 15-20kg/m ², far lower than concrete walls. This feature not only reduces building loads but also supports large-span installation, making it particularly suitable for large factories, storage facilities, and sports venues.
02
Environmental Protection and Durability
Polyurethane materials do not contain CFCs or HCFCs foaming agents, have zero ozone depletion potential (ODP), and the board can be 100% recycled. The surface coating adopts PVDF fluorocarbon paint, which has good weather resistance for many years and strong resistance to salt spray corrosion. It is suitable for corrosive environments such as coastal areas and chemical industries.
03
Aesthetics and functionality
The Sandwich Metal Siding Panel offers multiple colors, with over 100 standard color cards to choose from. Embossed textures such as wood grain, stone, etc. can be selected with over 100 color cards, and customized sizes are also supported. The hidden fastening system gives the exterior wall a seamless overall feel, while also providing waterproof and windproof functions.
04
Performance in cold regions
In extremely low temperature environments, Sandwich Metal Siding Panel exhibit comprehensive performance beyond traditional materials and become the preferred exterior wall for buildings in cold regions
Ultra low temperature insulation stability
The polyurethane sandwich layer maintains elasticity in an environment of -40 ℃, with small fluctuations in thermal conductivity. Effectively block the cold bridge effect. After installing this product, the indoor temperature difference increases by 25 ℃ compared to the outside, significantly reducing heating energy consumption.
Moisture resistance and anti condensation ability
The closed cell rate of the interlayer is as high as 92%, and the water vapor permeability is only 2.5ng/(Pa · m · s), far lower than that of rock wool. Avoid internal condensation during sudden temperature changes, protect the steel structure keel from freeze-thaw corrosion, and extend the service life of the building.
Extreme climate adaptability
The panel has passed low-temperature impact testing and has no risk of embrittlement or cracking. The connection part adopts a triple sealing design, which maintains airtightness in blizzard environments and meets the building certification standards for cold regions.
Detailed installation plan
The Sandwich Metal Siding Panel adopts a modular design, providing a "dry operation" installation system, greatly shortening the construction period and reducing labor costs
1. Basic preparation and measurement
Firstly, the flatness of the steel structure keel should be verified with a tolerance of ≤ 3mm/2m, and then the layout and positioning should be carried out according to the architectural drawings. It is recommended to use a total station to ensure the accuracy of the baseline and avoid cumulative errors.
2. Board installation process
Step 1: Fix the base
Install an L-shaped aluminum alloy bottom rail with a thickness of 2.5mm on the ground elevation line, fixed with stainless steel expansion bolts with a spacing of ≤ 600mm, and reserve a 5mm expansion gap at the joint.
Step 2: Vertical board splicing
Insert the wall panel vertically into the bottom rail, and use hidden male and female groove locks to ensure that the bite depth is ≥ 15mm to complete the horizontal connection. Vertically, self tapping screws are used to fix the C-shaped steel keel with a spacing of 400mm, and the screw torque is controlled at 0.6-0.8N · m.
Step 3: Node Processing
The internal and external corners are equipped with integrated corner boards with a length of 2.5m each. Special waterproof flashing boards are used around the window, and polyurethane sealant is filled at the joints to make the width ≥ 10mm.
3. Mechanized installation options
For walls with a height of ≥ 8m, it is recommended to use a vacuum suction cup lifting system to ensure a suction force of ≥ 25kPa. This, when combined with a gantry frame, can achieve a daily installation volume of 500-800 square meters, which is three times more efficient than manual installation.
Why is it corrosion-resistant?
The corrosion resistance of Sandwich Metal Siding Panel is attributed to the collaborative innovation of materials and structural design. Through a multi-layer composite protection system, the product can maintain long-term stability in extreme environments such as high temperature, high humidity, and high salt spray.
Substrate reinforcement
The panel is made of aluminum zinc coated steel plate with a coating amount of ≥ 275g/m ². Its zinc aluminum silicon alloy coating provides a dual mechanism of cathodic protection and barrier protection. Zinc sacrifices the anode to protect the steel substrate, while aluminum forms a dense oxide film of Al ₂ O3, which blocks the penetration of chloride ions.
Surface coating technology
The nickel plating layer utilizes the passivation ability of metallic nickel to generate a 2-3nm Cr ₂ O Ⅲ passivation film on the surface, which resists acid and alkali corrosion.
PVDF fluorocarbon coating
A coating system with high content of PVDF resin, which provides super strong chemical inertness through C-F bonds in the molecular chain with a bond energy of 485kJ/mol, and its UV aging resistance is 5 times higher than that of ordinary coatings.
Anti leakage of sandwich layer
The closed cell rate of polyurethane is as high as 92%, and the water vapor permeability is only 2.5ng/(Pa · m · s), blocking the migration path of water vapor and avoiding electrochemical corrosion caused by internal condensation.
