Aluminum is rustproof, with a good appearance, and the life of aluminum alloy is the longest.
However, aluminum alloy must also be carefully selected, choose a brand of good quality, and there is also a guarantee after sale.
If it is a mixed brand, they will add different amounts of waste aluminum at the time of production to offset some pure aluminum ingots, so that the whole cost price will be lower, but the quality can be imagined.
