Product Description

Product Advantages

High-strength structure, with reliable safety performance
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 and 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 resistance and 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 without fading or corroding.

Frequently Asked Questions

What ensures the high strength and safety of the aluminum profiles?
The profiles undergo precise heat treatment to enhance tensile strength, yield strength, and impact resistance. Their wall thickness is calculated through rigorous mechanical analysis to withstand extreme wind and seismic loads.
How effective is the sound insulation performance?
Equipped with a multi-chamber structure and multiple sealing designs, the profiles isolate 25-40 decibels of noise. Using them with insulating glass provides even greater noise mitigation against urban and industrial pollution.
How long do these aluminum profiles last under outdoor weather conditions?
They have a service life of over 50 years. The surface naturally forms a dense oxide film, complemented by advanced treatments like anodizing, electrophoretic coating, and powder spraying to resist UV rays, acid rain, and salt spray.
What testing standards do the surface coatings meet?
The multi-layer surface treatment processes enable the profiles to pass more than 2,000 hours of neutral salt spray testing, proving their resistance to long-term corrosion and color fading.
Can these profiles be used in prefabricated and municipal projects?
Yes, they are highly suitable for prefabricated structures (e.g., container houses) as well as municipal engineering installations like city railings, bus stops, billboards, and street lamp poles.
