Calculation Tools for Metal Gratings and Panels

Validation of Products and Processes

Validation is a systematic process that demonstrates that a product, process, or system meets established standards and specifications. This involves steps such as testing, inspecting, calibrating, and documenting. Validation is crucial for the reliability and safety of products. For example, the Eurocode provides guidelines for cold-formed profiles, but not for specific products like gratings.

Specific Standards for Stair Treads in the Eurocode

The Eurocode sets various standards to ensure the safety and durability of stair treads:

1. Dimensions: Minimum width and maximum rise height.
2. Anti-slip: Requirements for slip resistance to prevent slipping.
3. Handrails and balustrades: Mandatory presence and minimum height for safety.
4. Lighting: Adequate lighting for visibility.
5. Fire safety: Requirements for the fire resistance of stairs and stairwells.
6. Strength and stiffness: Stair treads must have sufficient load-bearing capacity and not bend excessively under load.
