1.3 PERFORMANCE REQUIREMENTS
A. Structural Performance: Engineer, fabricate, and install handrails, guardrails, and railing systems to withstand the structural loading required by applicable codes.
B. Thermal and Corrosion Control:
1. Allow for thermal action resulting from the maximum range (change) in ambient temperature in the design, fabrication, and installation of rail systems, to prevent opening of joints, buckling, and other detrimental effects, including overstressing of connections and components.
2. Prevent galvanic action and other forms of corrosion by isolating dissimilar metals, preventing direct contact with each other.
1.4 SUBMITTALS
A. Submit under provisions of Section 01300.
B. Product Data: Manufacturer's specifications and installation instructions for all components of each product type specified.
C. Shop Drawings: Prepared specifically for this project.
1. Show complete layout; plan views, elevations, connections, details for fabrication and attachment to other elements, and other installation details.
2. Include calculations signed and sealed by the registered engineer responsible for structural design of system.
1.5 QUALITY ASSURANCE
A. Manufacturer/Installer Qualifications: Provide handrails, guardrails, and railing systems from one source, produced by a manufacturer and craftsmen having resources to provide consistent quality in appearance and physical properties, without delaying the work.
1.6 DELIVERY, STORAGE, AND HANDLING
A. Deliver handrails, guardrails, railing systems, and related components in protective packaging. Inspect materials to ensure that specified products have been received.
B. Store components to avoid damage from moisture, abrasion, and other construction activities.
PART 2 PRODUCTS

2. Anchors and inserts as required to support work specified, in accord with approved shop drawings.
D. Fittings and Fasteners: Same basic material and alloy as parts being joined, unless otherwise indicated. Do not use metals that will be corrosive or incompatible with materials being fastened; do not utilize pop-rivets, sheet metal screws, adhesives, or cast fittings.
1. Fasteners: Series 300 stainless steel.
2. Component Fittings: Machined from solid 6063 alloy incorporating expanding internal tines.
2.3 MANUFACTURED UNITS
A. Railing System: "WESRAIL II" aluminum pipe component railing system and all related items, as supplied by Moultrie Manufacturing Company.
2.4 FABRICATION
A. Fabricate handrails and railing systems to comply with manufacturer's printed requirements, project design requirements, details, dimensions, finish and member sizes, including post spacing and anchorage, but not less than the structural requirements to support loading.
1. Clearly mark component units for site assembly and installation.
2. Use connections that maintain structural capacity of joined members.
B. Provide weep holes or other means to exit entrapped water from hollow sections of railing members exposed to exterior, condensation, or moisture from other sources.

3. Black Anodized.
4. Mil Finish Anodized (215R1).
B. Powder Coat Painted: Factory-applied, color selected by architect from manufacturer's standard colors.
PART 3 EXECUTION
3.1 EXAMINATION
A. Examine system components, substrate, and conditions where railing systems are to be installed.
B. Notify architect in writing of unsatisfactory conditions. Do not proceed with the work until unsatisfactory conditions have been corrected.
3.2 PREPARATION
A. Prepare surrounding construction to receive railing system installations to comply with manufacturer's requirements.
B. Review and coordinate setting drawings, shop drawings, templates, and instructions for assembly and installation of railing system and related items to be embedded in concrete and masonry.
3.3 INSTALLATION
A. Install railing system and related components in strict accordance with manufacturer's printed installation instructions and project shop drawings.
B. Preassemble railing system, including posts, in easy to lift sections whenever possible.
1. Align rails so that variations from level for horizontal members, and from parallel with rake of steps and ramps for sloping members, do not exceed 1/4 inch in 12 feet (6.3 mm in 3.657 m).
2. Separate aluminum which might contact concrete, masonry, or other metals, by means of asphaltic paint or other approved method to prevent electrolytic action.
C. Adjust, level, and securely install railing system components.
1. Avoid springing assembled components of system into place.
D. Install posts in concrete with pipe sleeves preset and anchored into concrete whenever possible, or by core drilling.
1. After posts are inserted, solidly fill the remaining space between post and side of sleeve or hole, with nonshrink nonmetallic grout to approximately 1/2 inch (13 mm) below exposed surface.
2. Install appropriate waterproof sealant as recommended by the manufacturer; slightly taper away from posts.
E. Provide for thermal expansion and contraction by use of expansion joints/gaps in top rails, 20 foot (6.096 m) maximum intervals.
1. Strictly adhere to manufacturer's instructions for locations of expansion joints and fastening of expansion sleeves.
2. Attach top rail to posts located at maximum 5 foot (1.524 m) on center spacings.
3. Install bottom rails in unspliced lengths between posts.
4. Install posts of continuous sections from mounting base to top rail.
F. Provide for water to drain from the railing system hollow sections by drilling weep holes at bottom locations or other approved methods.
3.4 CLEANING
A. Immediately upon completion of installation, clean all railing system surfaces using clean water and mild soap or detergent.
B. Do not use abrasive agent or harsh chemicals.
3.5 PROTECTION
A. Provide adequate protection for all surfaces of completed installations to prevent damage during remainder of construction activities.
