WESRAIL SAFETY RAIL
PART 1 – GENERAL
1..01 SECTION INCLUDES
A. (Component type) (Welded type) aluminum handrails, guardrails, and railing systems, including (connectors), fasteners and system required accessories.
1.02 SUBMITTALS
A. Product Data: submit manufacturer’s specifications and installation instructions for all components of each product type specified.
B. Shop Drawings: Show complete layout including plan views, elevations, (connections) (welds), details for fabrication and attachment to other elements, and other installation details. Include calculations signed and sealed by the registered engineer who was responsible for the structural design of the system.
1.03 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 Action 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 to prevent them from being in direct contact with each other.
1.04 QUALITY ASSURANCE
A. Manufacturer/Installing 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.
1.05 DELIVERY, STORAGE AND HANDLING
A. Deliver handrails, guardrails, and railing systems and related components in protective packaging and store components to avoid damage from moisture, abrasion and other construction activities.
PART 2 – PRODUCTS

D. Fittings and fasteners: Provide fittings and fasteners of same basic material and alloy as parts being joined, unless otherwise indicated. Provide Type 305 stainless steel blind rivets and self-tapping screws. Do not use metals that will be corrosive and incompatible with materials being fastened.
2.03 FABRICATION
A. Fabricate handrails and railing systems to comply with manufacturer’s written requirements, requirements for Project design, 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. Use connections that maintain structural capacity of joined members.
B. Provide weep holes or other means to exit entrapped water in hollow sections of railing members that are exposed to exterior or to moisture from condensation or other sources.
2.04 FINISHES
***SELECT ONE OR MORE OF THE FOLLOWING AVAILABLE FINISHES.***
A. Anodized Aluminum:
1. Clear Brushed Anodized; Aluminum Association AA M – 32, C – 22, A 41, with light circumferentially brushed finish before anodizing.
2. Dark Bronze Anodized.
3. Black Anodized
4. Mill Finish Anodized
5. Optional finish: Class I Architectural Finish – minimum 0.7 mil.
A. Powder Coat Painted, at factory. (Color to be selected by Architect from manufacturer’s standard array of colors).
PART 3 – EXECUTION
3.01 EXAMINATION / PREPARATION
A. Examine system components, substrate and conditions where railing systems are to be installed. Notify in writing of unsatisfactory conditions.
B. Prepare surrounding construction to receive railing system installations to comply with manufacturer’s requirements.
1. Review and coordinate setting drawings, shop drawings, templates, and instructions for assembly and installation of railing system, and related items that are to be embedded in concrete and masonry.
3.02 INSTALLATION
A. Install railing system and related components in strict accordance with manufacturer’s written 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 º inch in 12 feet.
2. Where aluminum might come into contact with concrete, masonry or other metals, separate materials to preventelectrolytic action by means of an asphaltic paint or other approved method.
A. Adjust, level and securely install railing system components.
1. Avoid springing assembled components of system into place.
A. Install posts into concrete with pipe sleeves preset and anchored into concrete whenever possible, or by core drilling. After posts have been inserted, solidly fill the remaining space between post and side of sleeve or hole, with nonshrink nonmetallic grout to approximately ½ inch below exposed surface. Install appropriate waterproof sealant, as recommended by manufacturer, to slightly taper away from post.
B. Provide for water to drain from the railing system’s hollow components by drilling weep holes at bottom locations or by providing other approved methods. Provide for thermal expansion / contraction by use of expansion joint / gap in top rails at maximum 20 foot intervals.
1. Adhere strictly to manufacturer’s instructions for locations of expansion joints and fastening of expansion sleeves.
***RETAIN 2 THROUGH 4 BELOW WHEN COMPONENT SYSTEM IS USED. DELETE WHEN ONLY WELDED SYSTEM IS REQUIRED***
2. Attach top rail to posts located at maximum five (5) foot on center spacing.
3. Install bottom rails in unspliced lengths between posts.
4. Install posts of continuous sections from mounting base to top rail.
3.03 CLEANING AND PROTECTION
A. Immediately upon completion of installations clean all railing system surfaces using cleanwater and mild soap or detergent. Do not use abrasive agents or harsh chemicals. Provide adequate protection for all surfaces of completed installations to prevent damage during remainder of construction activities.
