The material and construction of the aluminum veneer for building curtain walls

The aluminum sheet can be divided into two type that according to its specificationss :Aluminum Alloy Gusset Plate(Thickness <1.2mm), Aluminum Veneer(Thickness>1.5mm). Aluminum Veneer building curtain walls use the high-strength aluminum alloy plate and its commonly used thickness are 1.5mm, 2.0mm, 2.5mm and 3.0mm.That the structure of Aluminum sheet is mainly composed of panel, rib reinforcement and corner brace. The corner brace can be formed by the processing of bending and punching of the plane and it also can be riveted to the small edge of the plane. The rib reinforcement and the plane are made to a solid whole as they are connected with electric welding screw, and this processing can greatly enhances the strength and rigidity of the aluminum sheet curtain wall and ensures a good flatness and high anti-seismic and wind resistance in long-term use. If the functions of sound proof and heat preservation is necessary, that can install the eficient deadening and insulation material on the inside of the aluminum sheet.

The surface treatment of Aluminum Veneer for building curtain Walls

Aluminum sheet curtain wall surface generally use the fluorocarbon spraying treatment after chromaking and other pretreatments. Fluorocarbon coating mainly refers to KANAR500 and there are three kinds of fluorocarbon coating:primer coat, finish coat and varnish.Fluorocarbon coatings have excellent corrosion resistance and weather resistance, it can resist acid rain erosion, salt atmosphere corrosion and other air pollutants. And fluorocarbon coatings also possess excellent resistance to high temperature, fire protection, anti-aging and anti-UV properties, to meet the outdoor long-term use under harsh environmental conditions require.

Features of the aluminum veneer for building curtain walls

1.High Strength, Good Rigidity, Light in Weight 

2.Corrosion resistance:Corrosion resistant performance is good and without leg color up to 25 years of fluorocarbon paint.

3.Good manufacturability: The Aaluminum veneer of building curtain walls use the technology of processing before paint spraying, Aluminum sheet can be processed into various complex geometries such as plane, arc type and spherical surface. 

4.Resistance to staining: With the good non-adhesion function, that the sueface are difficult to attach pollutants and keep clean for a long time.

5.Convenient and efficient of Installation and construction:The Aaluminum veneer is formed in the factory, the construction site is not need processing but fix it simply.

6.Environmental:Aluminum sheet can be recycled 100%, the recycling value is higher.

7.Uniform coating, multi-colour: Advanced electrostatic spraying technology makes the attachment between the paint and the aluminum sheet with uniform thickness, smooth surface and high adhesion, and there are also have large choice space for it’s diversified color.

The installation of the aluminum veneer for building curtain walls

Tools:

Dentless saw blade cutter, electric hand drill, impact electric drill, nail gun, various specifications of drill flower, spanner, screwdriver, hammer, ink lines, nylon wire, steel tape, electric welder, Oxygen cutting equipment, injection glue gun, Pneumatic riveters, etc.

Preparatory work：

1.Material schedule

2.Construction schedule

Installation process 

Wire layout----fix the connection of the skeleton----fix the skeleton----install the aluminum veneer----Closing structure treatment----check up

1.Wire layout　

Fixed the skeleton to the main structure, please check the quality of the main structure before fix the skeleton.

2.Fix the connection of the skeleton

Welding connections on the column of the main structure to fix theskeleton.

3.Fix the skeleton

The skeleton shall make anti-corrosion treatment in advance.

Please ensure the firmness and accuracy of installation.

4.Install the aluminum veneer

The installation of aluminum plate should be firm and reliable.

The gap between the aluminum veneer should be treated internally to make it smooth and smooth.

Protect easily contaminated areas with plastic film or other materials.

Notes

1.The variety,quality, color, flower type and line shall shall conform to the design requirements and with the product qualification certificate.

2.The specifications and shape of curtain wall skeleton shall conform to the design requirements and the skeleton shall conduct rust removal and rust prevention treatment.
