.019'' (0.48mm) Thick Grey Color Coating Aliuminium Trim Coil for Aluminum Siding

.019'' (0.48mm) Thick Grey Color Coating Aliuminium Trim Coil for Aluminum Siding

Product Introduction

Aluminum alloy 3105 is essentially a 98% aluminum alloy with minor additions to increase strength over that of alloy 1100 and 3003. 

It is not hardenable by heat treatment and it has good corrosion resistance, formability and weldability.

PPAL are made of 3105 or equivalent aluminum alloy and H-16 or equivalent hardness.

then exterior PE paint or  PVdF paint are optional. This is our paint finish pre-coated aluminium that has the ability to be folded during fabrication 

without anydetriment to the surface.

Pre-painted (Color Coated) aluminum alloys coil is firstly painted on the surface of the aluminum plate with good color 

difference control and uniform paint film. It has the ability to be folded during fabrication without any detriment to the 

surface. For example, PVDF paint has high weather resistance, can be guaranteed 15 - 20 years color warranty.

All our pre-coat aluminium finishes are tough and hardwearing.

Product Processing

Production Process

unwiding---skimming(remove the oil and aluminum coil and aluminum debris)---cleaning---neutralization

(neutralize the residue inside the degreasing tank)---cleaning---chromizing(form chelete film to enhance adhesion 

between aluminum plate and coating)---drying---baking---cooling(by blowing, soaking and circulating water guiding system)---winding

T & D

Testing & Quality Control

A. From raw materials to process treatment, we cooperate with well-known brands with stable quality and reputation of the industry.
B. Adopting the German technology, through the three-times coating and baking, 12 testing procedures to ensure that no paint shedding,

bumps, coating voids.
C. The advanced colorimeter and error-detecting facility on thickness to ensure the quality.
D. The introduction of 8 advanced production lines from Germany, including four color layer lines, two cutting lines, two embossing lines, 

and a new production line of the protective film.
E. Full sets quality inspection: include the control of raw materials, the measurement of thickness and color difference during production, 

as well as the measurement of thickness and bending of products before packing.


Aluminum provides excellent insulating properties, especially the heavier-gauge metal. In fact, aluminum siding insulates 

a home better than vinyl siding and can save the homeowner a considerable amount on heating and cooling costs over the lifetime 

of the product. ... Unlike steel siding, aluminum does not rust. Aluminum siding is a very sturdy material that is less likely 

to crack or break than vinyl.

It can be repainted if you decide you don’t like the original colour later on. Vinyl siding can’t hold paint very well, and once 

you decide on a colour you can’t change it unless you are prepared to replace the siding.
