Several influencing factors of aluminum profile selection:
1. Load-bearing: Different profile specifications represent different load-bearing requirements, so you can choose suitable profile specifications according to specific load-bearing requirements.
2. Price: For the same specifications and models, the price may be different because the weight of the rice is different. Many customers choose lightweight aluminum profiles in order to save costs.
But what I want to remind everyone is that you can't choose unsuitable profile specifications just for the cost, it will only cause breakage or bending, which will affect the later use.
3. Frame structure: The specifications of the profiles used in different frame structures are also different. For some beams or columns, the load-bearing is to increase a little.
