Editor's Notes
July 02, 2019:
Depending on the width that you want your stairs to be, you might have to install additional stringers to prevent over-loading the step planks. The Pylex 13907 should be kept to under 41-inches unless a middle stringer is installed. Stairs of widths longer than 57 inches should be supported by 4 stringers. Some designs preclude installing additional stringers such as the Bilco SZ SL-SS. These can instead be supported by purpose-built stringers (which sort of defeats the purpose of buying pre-fabricated steel stringers).
Drilling and bolting onto masonry should be done with care to assure that the load is properly supported. You'll need specialized masonry drill bits and concrete fasteners. Ideally, you should use a hammer drill but a regular drill can also work well. Clear out the dust and a concrete screw will hold just fine.
If you are thinking about using steel stair stringers, you must first check your local building codes to make sure that they comply with regulations, particularly if they will be used in commercial settings. All installations should be performed by professional carpenters or masons to avoid injury or damage to property.
