Traditional Aluminum Profiles for Doors and Windows | Durable & Cost-Effective

When choosing a suitable door and window frame, what is really worth paying attention to is its quality and materials. A door and window should not only look good, but also stand the test of time.

When choosing materials, we have to distinguish between primary aluminum and recycled aluminum, because primary aluminum is a brand new aluminum material that has not been recycled, with high purity, stable performance, higher strength and durability, suitable for scenes with high requirements for material performance, and better surface treatment effect; while recycled aluminum is made from recycled waste aluminum, and there may be impurities, which affect the uniformity and strength of the material. The strength and toughness are relatively poor, and it is easy to deform or damage during use. Recycled aluminum has more impurities, is more difficult to process, and has poor surface treatment effect, which is prone to color difference or uneven texture.

Shenghai insists on using primary aluminum, which has pure materials, stable structures, and a service life of more than 20 years, truly achieving one-time installation and long-term worry-free. However, the recycled aluminum on the market has many impurities and is prone to fatigue. It may deform or age after about 10 years of use, and cannot guarantee long-term safety and performance.

When choosing door and window frames, the choice of materials is the key. Shenghai Aluminum uses various types of aluminum such as 6063/6061 T5/T6, with wall thickness controlled above 1.2mm. The thickness can also be customized according to your needs. Everything is based on your plan.

We Shenghai Aluminum have a professional technical team that can customize aluminum profiles of various shapes according to your drawings. At the same time, we can also provide a variety of surface treatment processes and high-precision deep processing services according to your needs to meet the personalized requirements of your project.

When choosing door and window frames, give priority to raw aluminum. Our Shenghai Aluminum has excellent performance and can provide reliable support for your construction projects.
