Preparation of channel steel before use
During production, processing, storage and transportation, channel steel may be affected by many different environments, such as oxidation and corrosion. In order to protect the surface of the steel and prevent it from continuing to be damaged, it is necessary to clean and paint the channel steel.
Cleaning: By cleaning the surface of channel steel, the surface dirt and rust can be effectively removed, thus reducing the degree of corrosion. Commonly used cleaning methods are water washing, mechanical rinsing, chemical cleaning and electrolytic cleaning.
Paint: channel steel paint is a way to protect steel from corrosion, enhance adhesion, beautify the surface. Before painting, it is necessary to select the appropriate paint, coating process, and coating and drying treatment.
When carrying out the installation, commissioning, maintenance and other operations of channel steel, you need to pay attention to the safety protection measures.
1. Wear safety protection equipment: including safety shoes, safety helmets, protective gloves, etc.
2. Use suitable tools: use tools that meet the standard, avoid using tools that are corroded and badly worn.
3. Pay attention to the construction environment: the construction environment should be dry, clean and ventilated, and ensure that there are no open flames, flammable materials and other dangerous things.
4. Reasonable placement: in the process of using channel steel, you need to reasonably placed to deal with the remaining steel, to prevent the steel from slipping, resulting in safety accidents.
5. Reasonable maintenance: steel should not be arbitrarily disassembled, destroyed, to avoid leaving hidden danger to the subsequent use.
Transportation and installation are also the preparatory work to be carried out before using channel steel.
1. Choose the appropriate mode of transportation: steel transportation needs to choose the appropriate means of transportation, and proper bundling and tightening.
2. The loading and unloading of channel steel needs to be carried by professional equipment or manpower: professional equipment should be used for loading and unloading installation, or to avoid accidental injury caused by manpower handling.
3. In the process of installation, it is necessary to pay attention to the siting of the foundation and the verticality of the steel and other issues: make sure that the verticality of the foundation meets the specification requirements, avoiding the steel to cause skewing. And measure the hole position and installation site of channel steel to ensure that it meets the specification requirements.
