Precast concrete step

• Square or stooled end built into wall 
• Support wall 
• Cantilever step 
• Precast concrete cantilever steps built into wall forming stairs 
• Delivery of precast concrete stairs should be arranged so that they can be lifted , positioned and fixed direct from the delivery vehicle , thus avoiding double handling . 
• Precast components are usually designed for 2 conditions :-

1. Lifting and transporting 
2. Final fixed condition 

• Flights are lifted from the correct lifting points , which may be in the form of loops or hooks projecting from or recessed into the concrete member .

1. TO avoid damage due to unacceptable stresses during lifting . 

• Balustrade and handrail requirements , and the various methods of fixing , are as described for in-situ RC stairs . 
• ANy tread finish that is acceptable for an in-situ RC stair will also be suitable for the precast concrete stair .
