Two look at processing. The pattern aluminum plates produced by the regular large factories are fastidious in materials, bright and bright in surface, clear and orderly in patterns, flat in surface and free from oil stains, scratches and injuries; while the pattern aluminum plates produced by the small factories are made of waste aluminum, with dull and matte surface, unclear and irregular patterns, irregular in surface, poor performance and quality. Quantity difference.
三看价格。花纹铝镁锰板分为纯铝与合金两种,其价格天然也不一样。正规厂家生产的花纹铝镁锰板加工费一吨在几千元,合金价格要高于纯铝,正规厂家的铝镁锰板价格比起劣质铝镁锰板要高20%-30%左右。企业在采购时关键词优化,切忌不可单比价格,买到不合格产品,则悔之晚矣。
