金属风管加工的常用材料。
Common materials for metal air duct processing.
在通风空调工程中，常用的主材有板材、型钢；常用辅材有垫料、螺栓和螺母、铆钉；耗材有氧气、乙炔、锯条、焊条等。
In ventilation and air conditioning engineering, the main materials commonly used are plate and section steel; Common auxiliary materials include padding, bolts, nuts and rivets; Consumables include oxygen, acetylene, saw blade, welding rod, etc.
首先，我们来学习金属风管主材，板材。在金属风管的加工中，金属板材可以分为普通薄钢板、镀锌薄钢板、铝及铝合金板、不锈钢板、塑料复合钢板等。下面通过的对比认识每一种钢板的特点：
First, let's learn the main material of metal air duct, plate. In the processing of metal air duct, metal sheet can be divided into ordinary sheet steel, galvanized sheet steel, aluminum and aluminum alloy plate, stainless steel plate, plastic composite steel plate, etc. The characteristics of each steel plate are recognized through the following comparison:
1．普通薄钢板——厚度0.5-2.0mm，价格便宜，易加工，易生锈
1. Ordinary steel sheet - 0.5-2.0mm thick, cheap, easy to process and rust
2．镀锌薄钢板——厚度0.25-2.0mm，具有良好耐腐蚀性能
2. Galvanized steel sheet - 0.25-2.0mm thick, with good corrosion resistance
3．铝及铝合金板——耐腐定州苗木  保定网站建设 保定电动门 保定空压机 化粪池模具 微型蠕动泵 上海起帆电缆蚀，易加工，常用于防爆系统
3. Aluminum and aluminum alloy plate - corrosion resistant, easy to process, commonly used in explosion-proof system
4．不锈钢板——高强度，高耐腐蚀性，常用于化学工业通风系统
4. Stainless steel plate - high strength, high corrosion resistance, commonly used in chemical industry ventilation system
5．塑料复合钢板——强度高，耐腐蚀，常用于防尘要求较高的系统空调和耐腐蚀的风管。
5. Plastic composite steel plate - high strength, corrosion resistance, commonly used in air conditioning systems with high dust requirements and corrosion-resistant air ducts.
