Interior Stairs
Description
- Work scopes in this area may include: installing new concrete or metal stairs and treads, replacing and/or repairing railings and balustrades, and installing new low-voltage and IT infrastructure in stairwells. Note that for stair halls and lobby stairs, as well as exterior rails at stairs and ramps, a finish of field-painted steel tube rails will not be sufficient. The primer and paint layers will wear down to the bare metal on the handrail portion, and it is difficult to maintain. It is preferable to specify a handrail either without an applied finish such as stainless steel or aluminum, a factory-applied powder-coated finish, or for interior applications a heavy-duty flame-resistant textured PVC rail cover such as those used in hospitals, anchored to the rails with tamper-proof screws. This also applies to Newel post caps.
