RAILING DESIGN

General Information

  1. This catalog provides general guardrail configurations and components to the requirements of the latest Ontario Building Code (1997).
  2. The ability of supporting floor and wall structures to resist the effects of the loads of these components either singly or in combination with other loads and effects remain the sole responsibility of the project architect/engineer.
  3. 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 guardrailand shall be the manufacturers responsibility that the design requirements are met. (see standards on next page).
  4. The manufacture and installation of guardrails and their components shall be in strict accordance with shop drawings and specifications prepared by Greco Aluminum Railings.
  5. Greco's shop drawings are sealed by a qualified Professional Engineer who specializes in our welded aluminum railing system. Shop drawings prepared for projects in other jurisdictions will comply with their respective building code.
