　　山东通风管道板材:黑铁皮与白铁皮

　　Shandong Ventilation Pipeline Plate: Black Iron and White Iron暖通空调系统主要包括通风工程和空调工程两大局部。通风工程普通包括送风和排气、除尘和工程。空调工程普通包括空调、恒温恒湿和空气净化工程。

　　HVAC system mainly includes two parts: ventilation engineering and air conditioning engineering. Ventilation engineering generally includes air supply and exhaust, dust removal and detoxification engineering. Air conditioning engineering generally includes air conditioning, constant temperature and humidity and air purification engineering.

　　通风工程与空调空调系统需求经过风道衔接，完成2F黑铁皮普通酸洗钢板(黑铁皮)的设计功用:由碳钢经热轧或冷轧制成。热轧钢过程的,由于很容易突破和空调用于冷轧,模型普通有Q195、Q215 Q235,有两品种型的表和线圈,常用的厚度为0.5 ~ 2毫米,黑色板近年来在暖通空调工程运用纯黑色单少,黑铁和锡的区别不是黑钢板外表处置,容易氧化和生锈。

　　Ventilation works and air conditioning systems need to be connected through air ducts to complete the design function of 2F black iron sheet common pickling steel sheet (black iron sheet): made of carbon steel by hot or cold rolling. Hot rolled steel process, because it is easy to break through and air conditioning is used for cold rolling, the model generally has Q195, Q215 Q235, there are two types of surface and coil, the commonly used thickness is 0.5-2 mm, black sheet in recent years in HVAC engineering using pure black sheet, black iron and tin is not the difference between the surface treatment of black steel plate, easy oxidation and rust.

　　锡

　　tin

　　镀锌钢板(铁皮):由镀锌黑铁皮制成，俗称铁皮。常用厚度0.5~1.5mm，规格尺寸与普通薄钢板(黑铁皮)相同。镀锌层厚度不小于0.02mm。镀锌铁的优点:外表具有防腐作用，所以普通不需求刷油防腐，普通用于保送酸雾作用的湿润环境通风系统和空调系统及配件。

　　Galvanized steel sheet (iron sheet): Made of galvanized black iron sheet, commonly known as iron sheet. Commonly used thickness is 0.5-1.5 mm, the size is the same as that of ordinary thin steel plate (black iron sheet). The thickness of galvanized layer is not less than 0.02mm. Advantages of galvanized iron: The appearance has anti-corrosion effect, so it is not required to brush oil and anti-corrosion. It is commonly used for humid environment ventilation system and air-conditioning system and accessories to protect acid fog.
