Q. What are the disadvantages of steel staircase?

Answer

Here are some disadvantages of steel staircase:Conductor of heat: Poorly fireproofed steel can start fires when it becomes hot and touches combustible substances. The cost of building is increased by the necessity of fireproofing steel stairways to prevent fire tragedies.Manufacturing inconsistencies: Incorrectly removing scraps during production might introduce impurities into the steel which could cause a microcrack to open up and quickly grow into a wider crack resulting in a fracture. Limited capacity for on-site customization: A prefabricated steel staircase as opposed to one manufactured from wood is often provided in set dimensions. So if there is a problem with the measurements the installation process will be delayed until the problem is fixed.
