ALUMINUM PEDESTRIAN HAND RAILINGS.
Aluminum hand railings shall be constructed of aluminum posts supporting rails of
aluminum tubing in accordance with the contract documents and the following:
A. Materials.
Materials shall meet the following requirements:
1. Aluminum Parts.
Section 4190 shall apply.
2. Anchor Bolts, Nuts, and Washers.
Article 4153.06 shall apply unless otherwise shown in the contract documents.
B. Handling and Storage.
The aluminum posts and rails shall be carefully handled and stored at the site of the
work. Aluminum parts shall not be stored in contact with the ground or where they
may be attacked by acid or alkali. Members which are marred or damaged to the extent
that their usefulness or appearance is impaired shall be replaced at the expense of the Contractor.
C.
Installation.
Anchor bolts shall be set in the concrete curb at the correct location and
elevation. They shall be firmly held in place by suitable templates that will insure
their correct position during placing and hardening of the concrete.
Rails shall be assembled, aligned, and brought to the correct elevation by shimming, when necessary. Anchor nuts shall be tightened to hold the rail firmly in place. After the rail has been aligned, the tubular rails shall be positioned to provide the desired expansion, the setscrews tightened to hold the rails firmly in place, and the ends capped.
After erection, the rails, posts, and concrete around the post base shall be carefully cleaned of all dirt or grease by means approved by the Engineer.
