RAILING DESIGN
General Information
- This catalog provides general guardrail configurations and
components to the requirements of the latest edition of B.O.C.A.
National Building Code.
- The ability of supporting floor and wall structures to resist the
effects of loads of these components alone or in combination with other
loads and effects remains the sole responsibility of the project
architect / engineer.
- The complete design and preparation of shop drawings for the
aluminum railing system and all related items are designed for each
individual project. Posts and anchorage vary in size and quantity for
each type of guardrail and shall be the manufactures responsibility that
the design requirements are met.
- The manufacture and installation of guardrails and their components
shall be strict in accordance with shop drawings and specifications
prepared by Greco Aluminum Railings.
- Greco's shop drawings are sealed by a qualified Professional
Engineer who specializes in our welded aluminum railing systems. Shop
drawings prepared for projects in other jurisdictions will comply with
their respective building codes.

following structural loads without exceeding the allowable design
working stress of the materials for railing system, anchors and
connections.
1.05 Submittals
- Shop drawings showing Welding, Fabrication, Installation or railing
system including all plans, sections, detail of connections and
components.
