Final answer:
Skylight screens must withstand loads and forces to ensure safety and comply with building codes. They use materials like stainless steel to maintain structural integrity and appear seamless when reflecting the sky.
Step-by-step explanation:
Skylight screen grillwork or slatwork is designed to provide safety by preventing falls through the skylight, and it must be capable of withstanding certain loads and forces to be compliant with building codes and safety standards. The design and materials used, such as the stainless steel in Figure 7.8.32, must be strong and durable enough to support the weight of individuals, snow, ice, or equipment that may come in contact with the skylight. The structural integrity of the skylight screen ensures that the panels, when the light shines on them, do not distort or break, allowing them to reflect the sky and appear as one seamless piece.
