The Characteristics Of Aluminum Alloy Doors And Windows Compared With Steel Wood Doors And Windows, Aluminum Alloy Doors And Windows Have The Following Advantages:

1) Light Weight And High Strength: The Density Is Only 1/3 Of That Of Steel. The Surface Of Aluminum Alloy Doors And Windows Has Artificial Oxide Film And Is Colored To Form A Composite Film Layer. This Composite Film Is Not Only Corrosion-resistant And Wear-resistant, But Also Has A Certain Fire Resistance And High Gloss. Due To Its Light Weight, The Processing And Assembly Are Precise And Accurate. Therefore, The Opening And Closing Are Light And Flexible, And There Is No Noise.

2) Good Sealing Performance: The Sealing Performance Directly Affects The Use Function And Energy Of Doors And Windows. The Sealing Performance Includes Four Aspects: Air Tightness, Water Tightness, Heat Insulation And Sound Insulation.

3) Good Durability, Easy To Use And Maintain: Aluminum Alloy Doors And Windows Do Not Rust, Fade, Or Fall Off, Almost No Maintenance Is Required, And The Service Life Of Spare Parts Is Extremely Long.

4) Elegant Decoration Effect: The Surface Of Aluminum Alloy Doors And Windows Has Artificial Oxide Film And Is Colored To Form A Composite Film Layer. This Composite Film Is Not Only Corrosion-resistant And Wear-resistant, But Also Has A Certain Fire Resistance And High Gloss. Due To The Light Weight Of Aluminum Alloy Doors And Windows, The Processing And Assembly Are Precise And Accurate, So The Opening And Closing Are Light And Flexible, And There Is No Noise.

Consumers Should Pay Attention To The Following Points When Purchasing:

1) Thickness: Aluminum Alloy Sliding Doors Are Available In 70 Series, 90 Series, Etc. The Series Number Indicates The Thickness Of The Door Frame In Millimeters Of The Construction Dimension. Aluminum Alloy Sliding Window Has 70 Series, 90 Series And So On. The Selection Of The Series Should Be Determined According To The Size Of The Window Opening And The Local Wind Pressure Value. Aluminum Alloy Sliding Windows Used As Enclosed Balconies Shall Be No Less Than 70 Series.

2) Strength: The Tensile Strength Should Reach 157 Newtons Per Square Millimeter, And The Yield Strength Should Reach 108 Newtons Per Square Millimeter. When Purchasing, You Can Bend The Profile Moderately With Your Hands, And It Should Be Able To Return To Its Original Shape After Letting Go.

3) Chromaticity: The Color Of The Same Aluminum Alloy Profile Should Be The Same. If The Color Difference Is Obvious, It Is Not Suitable For Purchase. The Broken Bridge Aluminum Doors And Windows Are Tightly Closed, With Excellent Air-tightness And Water-tightness, And Excellent Thermal Insulation Performance; The Window Sash Adopts An Insulating Glass Structure, Which Makes The Window Truly Show Sound Insulation, Heat Insulation, Thermal Insulation, And Excellent Functions, Saving A Lot Of Heating And Cooling Costs.

4) Flatness: When Inspecting The Surface Of Aluminum Alloy Profiles, There Should Be No Dents Or Bulges.

5) Gloss: Aluminum Alloy Doors And Windows Should Avoid Buying Profiles With Open Air Bubbles And Slag, As Well As Cracks, Burrs, Peeling And Other Obvious Defects. The Quality Of Aluminum Alloy Doors And Windows Can Be Roughly Judged From The Selection Of Raw Materials, The Surface Treatment And Internal Processing Quality Of Aluminum Materials, And The Price Of Aluminum Alloy Doors And Windows.

6) Degree Of Oxidation: The Thickness Of The Oxide Film Should Reach 10 Microns. When You Choose To Buy, You Can Swipe On The Surface Of The Profile To See If The Oxide Film On The Surface Can Be Wiped Off.
