When constructing a guardrail system, what should be avoided?

When constructing a guardrail system, it is crucial to avoid using materials that can bend. The integrity and effectiveness of a guardrail depend heavily on its ability to withstand forces such as impact and load without deforming. If the materials used can bend or flex under pressure, the guardrail may not provide the necessary protection or support. This could lead to failures in the system during critical situations, thereby compromising safety standards.

The other considerations, such as ensuring the proper height, installing at least two rails, and appropriately spacing vertical posts, are all important for creating a robust and safe guardrail system. These factors help in preventing falls and ensuring that the guardrail serves its purpose effectively, highlighting the importance of rigid and strong materials as a foundational element of the construction process.
