1.04 SYSTEM DESCRIPTION
Structural Performance of Guardrail and HandRail Systems: Engineer, fabricate and install handrails and railing systems to withstand the following structural loads without exceeding the allowable design working stress of the materials for handrails, railing systems, anchors and connections. Apply each load to produce the maximum stress, by applying a multiplying factor of 2.5 to the required design load, in each of the respective components comprising handrails and railing systems. All Rail Systems have been test to the AC-174 Accept Criteria for Deck Span and Guard Rail Systems.
Top Rail of Guardrail Systems: Capable of withstanding the following loads applied as indicated:
Concentrated load of 500 lbs applied at mid point and in horizontal direction. Uniform load of 125 plf applied at quarter points in a horizontal direction and concurrently with a uniform load of 125 plf applied vertically downward. Concentrated and uniform loads shall not be applied simultaneously.
Handrails Not Serving as Top Rails: Capable of withstanding the following loads applied as indicated:
Concentrated load of 125 lb applied in a horizontal direction.
Concentrated and uniform loads shall not be applied simultaneously.
Infill Area of Guardrail Systems: Capable of withstanding a horizontal concentrated load of 125 lb applied to a 1 sq ft (976 kg/m2) area at any point in the system, including panels, intermediate rails, balusters or other elements composing the infill area.
Above load need not be assumed to act concurrently with loads on top rails of railing systems in determining stress on guardrail.
Infill loads shall be recalculated after flexural testing is completed from materials property testing.

PART 2 – PRODUCTS
2.01 RAILING SYSTEM
Specifier Note: Alternative material handrails are becoming popular choices for architects and builders on residential and light commercial projects of many types. Alternative material railing products are intended to provide safe, decorative and low maintenance components for use as a railing on steps, porches and decks. Melton Classics’ vinyl and composite products will not rot, rust, chip, flake or corrode. They are low maintenance and will withstand harsh weather conditions, including temperature changes and intense ultraviolet light
Specifier Note: Melton Classics’ vinyl products are manufactured from 100% new vinyl. The base ingredient is rigid PVC (polyvinyl chloride) homopolymer compound with a high level of titanium dioxide pigment for long-term UV resistance and impact modifiers for strength. The formulation is similar to that of vinyl siding and windows, which have more than 20 years of proven long-term durability and structural integrity. The profiles are free from visible cracks, holes, foreign inclusions or other defects. They are uniform in color, capacity and density. Cost: The initial material cost of vinyl is slightly higher than wood. However, due to virtually no maintenance or replacement cost, enhanced property value and the manufacturer’s transferable warranty, the life cycle cost can be much lower than alternative materials. Budget cost information may be obtained from Melton Classics Inc. at 800-963-3060.

Site Visits: [Specify number and duration of periodic site visits.].
Specifier Note: PVC fencing, deck and rail materials offer very low maintenance. They never need painting and are not subject to deterioration. These assemblies will get dirty just as any other product exposed to atmospheric conditions. An occasional pressure washing or cleaning with a long-handled soft-bristle brush of the type used to wash cars may be all that is necessary. If dirt is hard to remove, wipe down the PVC with a solution of 1 cup Simple Green to 1 gallon of water. Tide, Spic ’n Span or other household detergent may also be used. For stubborn stains, consult the manufacturer’s literature.
Cleaning: Remove temporary coverings and protection of adjacent work areas. Repair or replace products that have been installed and are damaged. Clean installed products in accordance with manufacturer’s instructions prior to Owner’s acceptance. Remove construction debris from project site and legally dispose of debris.
