Welded roof protective guardrail is a safety device manufactured by welding technology to protect the roof structure and prevent people from falling. These guardrails are usually made of steel and are designed to be durable enough to withstand the impact of weight and wind to ensure the safety of roofing workers.
### Production Process:
1. **Design and planning**: First of all, design the size, height, spacing and other parameters of the guardrail according to the actual situation of the roof (such as height, width, slope, etc.) and safety specifications.
2. **Material Selection**: Choose the right steel as the raw material, the common ones are angle steel, round pipe or square pipe, etc., and its strength, corrosion resistance and other factors should be considered.
3. **Cutting & Processing**: Use a metal cutting machine or hand tool to cut the steel into parts of the desired shape and size, such as columns, crossbars, etc., and carry out the necessary grinding treatment to remove burrs and ensure the flatness when welding.
4. **Welding**: Arc welding, gas shielded welding and other methods are used to connect the components. During the welding process, it is necessary to pay attention to maintaining the firmness and aesthetics of the welding point to avoid cracks or poor welding.
5. **Anti-corrosion treatment**: In order to prolong the service life of the guardrail, the guardrail after welding should be treated with anti-corrosion, such as anti-rust paint, hot-dip galvanizing, etc.
6. **Installation**: Fix the guardrail on the roof according to the position of the design drawings to ensure that each connection point is stable and reliable.
7. **Inspection and acceptance**: After completing the installation, conduct a comprehensive inspection to ensure that the guardrail is not loose, broken and other problems, and meets the safety standards.
### Notes:
- Ensure that all welding operations comply with relevant safety regulations and that appropriate personal protective equipment is used.
- Anti-corrosion treatment is a key step to effectively extend the service life of the guardrail.
- Regularly check the condition of the guardrail and repair the damaged parts in time to maintain their safety performance.
Welded roof guardrails not only provide physical protection, but also reflect the importance of worker safety, which is one of the indispensable safety measures in building construction.
