Product Description

Product Description

High-Strength Structure & Reliable Safety

The aluminum alloy undergoes precise heat treatment, featuring excellent tensile strength, yield strength and impact resistance. The wall thickness of the profiles has been calculated through rigorous mechanical analysis, enabling it to withstand extreme loads such as strong winds and earthquakes, thereby fully ensuring the safety of the building structure.

Excellent Sound Insulation & Noise Reduction

The multi-chamber structure combined with multiple sealing designs can effectively isolate 25-40 decibels of noise. When used in conjunction with insulating glass, the sound insulation effect is even better, perfectly solving the problems of urban traffic, industrial and daily noise pollution, and creating a quiet and comfortable environment indoors.

Superior Weather & Corrosion Resistance

The aluminum alloy surface naturally forms a dense oxide film. Combined with multi-layer surface treatment processes such as anodizing, electrophoretic coating, fluorocarbon spraying, and powder spraying, it can pass more than 2,000 hours of neutral salt spray tests. It has excellent resistance to ultraviolet rays, acid rain, and salt spray, and can last for more than 50 years, remaining unchanged, not fading, and not corroding over a long period of use.

Frequently Asked Questions

How does the structural design of these aluminum profiles ensure building safety?

The profiles undergo precise heat treatment for excellent tensile and impact resistance. Additionally, the wall thickness is determined through meticulous mechanical analysis, enabling the structure to withstand heavy loads from strong winds and seismic activities.

What is the noise reduction capability of these profiles?

Thanks to their multi-chamber structure and multiple sealing designs, they can isolate between 25 and 40 decibels of noise. When combined with insulating glass, they provide superior sound barrier performance against urban, traffic, and industrial noise.

How do these profiles achieve a service life of over 50 years?

They feature a naturally forming dense oxide film combined with multi-layer treatments like anodizing, electrophoresis, fluorocarbon, and powder spraying. This allows them to pass a 2,000-hour neutral salt spray test, ensuring resistance to UV rays, acid rain, and general corrosion.

What residential applications are these aluminum profiles suitable for?

They are commonly applied in residential environments for system doors and windows, balcony railings, sunrooms, security nets, and stair handrails.

Can these profiles be used in large-scale commercial and public municipal projects?

Yes, they are highly versatile and suitable for commercial glass curtain walls, prefabricated buildings, public venues (such as airports, schools, and stadiums), and municipal infrastructure like billboards, bus stops, and street lamp poles.
