Material quality: When purchasing, check the material of the composite board to ensure that it meets the requirements. Composite plates are usually composed of two or more layers of steel plates of different materials, with the outer layer generally being colored coated steel plates and the inner layer being ordinary steel plates or other metal materials. When purchasing, it is important to ensure that the selected composite board has sufficient strength and durability.

加工工艺：复合板的加工工艺对其质量和使用寿命也有重要影响。在选购时，要注意检查复合板的加工工艺是否精细，边缘是否平整，是否存在毛刺、变形等问题。

Processing technology: The processing technology of composite plates also has a significant impact on their quality and service life. When purchasing, it is important to pay attention to checking whether the processing technology of the composite board is fine, whether the edges are flat, and whether there are problems such as burrs and deformation.

尺寸和厚度：根据实际需要，选择符合尺寸要求的复合板。同时，要确保所选复合板的厚度符合要求，能够满足强度和耐久性的需求。

Size and thickness: Select composite plates that meet the size requirements according to actual needs. At the same time, it is necessary to ensure that the thickness of the selected composite board meets the requirements and meets the requirements for strength and durability.

外观质量：选购时要检查复合板的外观质量，包括表面是否平整、有无气泡、划痕、裂纹等缺陷。

Appearance quality: When purchasing, the appearance quality of the composite board should be checked, including whether the surface is flat, whether there are defects such as bubbles, scratches, and cracks.

和认证：选择知名的复合板，并确保所选产品通过认证，如ISO9001、ISO14001等。这有助于保证产品质量和售后服务。

Brand and certification: Select well-known brands of composite boards and ensure that the selected products pass international certification, such as ISO9001, ISO14001, etc. This helps to ensure product quality and after-sales service.

：在考虑选购复合板时，也是一个重要的考虑因素。要结合自己的实际需求和预算，选择性价比合适的复合板。

Price: When considering purchasing composite boards, price is also an important factor to consider. To choose a cost-effective composite board based on one's actual needs and budget.

防潮性能：由于复合板由不同材料组成，其防潮性能可能会有所不同。在选购时，要注意检查复合板的防潮性能，以避免在使用过程中出现膨胀、变形等问题。

Moisture resistance: Due to the composition of different materials, the moisture resistance of composite boards may vary. When choosing, it is important to check the moisture-proof performance of the composite board to avoid problems such as expansion and deformation during use.

性：现代人在选购材料时越来越注重性。在选购复合板时，要尽量选择性较好的产品，如可回收利用的复合板或是低甲醛含量的产品。

Environmental friendliness: Modern people are increasingly paying attention to environmental friendliness when choosing materials. When choosing composite boards, it is important to choose environmentally friendly products, such as recyclable composite boards or products with low formaldehyde content.
