The difference between national standard aluminum and non-standard aluminum:
1. Due to differences in thickness, raw materials, and other factors, the cost-effectiveness of the two varies. Compared to the two, the national standard of bridge breaking aluminum has a higher cost-effectiveness. The national standard of bridge breaking aluminum has higher requirements for strength, hardness, and toughness than non national standards.
2. Literally, it means the difference between meeting national standards and not meeting national standards. Non standard aluminum materials are made of recycled materials, and some impurity elements cannot be controlled within the limited range, which will exceed the standard; National standard aluminum requires the content of each element to be controlled within a limited range.
3. Quality difference: National standard aluminum is superior to non-standard aluminum in terms of hardness, compressive strength, and appearance color. National standard aluminum can meet the hardness requirements of the product, but non-standard aluminum is difficult to achieve, which is reflected in the load size and compressive strength of the greenhouse in later use, seriously affecting the quality of the greenhouse.
4. Price difference: the non-standard ones are priced according to the amount exceeding the standard, and the market price difference of some varieties is about 2000 yuan/ton; The national standard aluminum price fluctuates according to market prices, and the price difference will not be significant.
5. Differences in production standards: National standards refer to aluminum products manufactured according to national requirements, while non national standards refer to aluminum products made according to customer needs.
6. Thickness difference: Compared with non national standard bridge cutoff aluminum, the thickness of national standard bridge cutoff aluminum is more standardized, generally 1.4 centimeters or greater.
