Patent attributes
The present invention relates to the field of railing and fencing systems. More particularly, embodiments of the present invention relate to modular railing/fencing systems comprising extruded aluminum railings with cellular polyvinyl chloride (PVC) panel inserts having an impact resistance of up to about 350 lb/ft2, which combined provide a system capable of withstanding significant external forces. Particular embodiments of the invention include modular fencing systems comprising: a) one or more upright vertical post members; b) upper and lower horizontal guardrails with a longitudinal panel-receiving channel; c) one or more cellular polyvinyl chloride (PVC) panel inserts operably configured for insertion in the panel-receiving channels of the upper and lower guardrails; d) wherein, upon installation, the system is capable of receiving a load normal to the panel ranging from about 180 to about 360 lb/ft2 without failure. Cellular PVC panels for use in such systems are also included.
